Subject: [PATCH 01/24] feat(backend): add vfox backend hooks support

Add support for vfox plugins that implement backend hooks, allowing
plugins to provide custom implementations for version listing, installation,
and environment setup. This enables more flexible plugin architectures
while maintaining backward compatibility with traditional vfox plugins.

- Add BackendExecEnvContext, BackendInstallContext, and BackendListVersionsContext
- Enhance VfoxBackend to support both traditional and backend-only plugins
- Add new backend hook types in vfox crate
- Include comprehensive test coverage for vfox backend functionality
- Update plugin system to handle vfox backend plugin types

+# asdf (Legacy) Plugins
+
+mise maintains compatibility with the asdf plugin ecosystem through its asdf backend. These plugins are considered legacy because they have limitations compared to mise's modern plugin system.
+
+## What are asdf (Legacy) Plugins?
+
+asdf (legacy) plugins are shell script-based plugins that follow the asdf plugin specification. They were the original way to extend tool management in the asdf ecosystem and are now supported by mise for backward compatibility.
+
+## Limitations
+
+asdf (legacy) plugins have several limitations compared to mise's modern plugin system:
+
+- **Platform Support**: Only work on Linux and macOS (no Windows support)
+- **Performance**: Shell script execution is slower than mise's native backends
+- **Features**: Limited compared to modern backends like aqua, ubi, or mise plugins
+- **Maintenance**: Harder to maintain and debug
+- **Security**: Less secure than sandboxed modern backends
+
+## When to Use asdf (Legacy) Plugins
+
+Only use asdf (legacy) plugins when:
+
+- The tool is not available through modern backends (aqua, ubi, etc.)
+- You need compatibility with existing asdf workflows
+- The tool requires complex shell-based installation logic that can't be handled by modern backends
+
+**For new tools, consider these alternatives first:**
+1. [aqua backend](dev-tools/backends/aqua.md) - Preferred for GitHub releases
+2. [ubi backend](dev-tools/backends/ubi.md) - Simple GitHub/GitLab releases
+3. [Language package managers](dev-tools/backends/) - npm, pipx, cargo, gem, etc.
+4. [mise plugins](plugin-development.md) - Custom cross-platform plugins
+
+## Installing asdf (Legacy) Plugins
+
+### From the Registry
+
+Most popular asdf plugins are available through mise's registry:
+
+```bash
+# Install from registry shorthand
+mise use postgres@15
+
+# This is equivalent to
+mise use asdf:mise-plugins/mise-postgres@15
+```
+
+### From Git Repository
+
+```bash
+# Install plugin directly from repository
+mise plugin install <plugin-name> <git-url>
+
+# Example: PostgreSQL plugin
+mise plugin install postgres https://github.com/mise-plugins/mise-postgres
+```
+
+### Manual Installation
+
+```bash
+# Add plugin manually
+mise plugin add postgres https://github.com/mise-plugins/mise-postgres
+
+# Install tool version
+mise install postgres@15.0.0
+
+# Use the tool
+mise use postgres@15.0.0
+```
+
+## Plugin Structure
+
+asdf (legacy) plugins follow this directory structure:
+

+
+## Best Practices
+
+### Error Handling
+
+```bash
+#!/usr/bin/env bash
+set -euo pipefail  # Exit on error, undefined vars, pipe failures
+
+# Check dependencies
+command -v curl >/dev/null 2>&1 || {
+  echo "Error: curl is required" >&2
+  exit 1
+}
+```
+
+### Cross-Platform Compatibility
+
+```bash
+#!/usr/bin/env bash
+
+# Detect platform
+case "$(uname -s)" in
+  Darwin*) platform="darwin" ;;
+  Linux*)  platform="linux" ;;
+  *)       echo "Unsupported platform" >&2; exit 1 ;;
+esac
+
+case "$(uname -m)" in
+  x86_64) arch="amd64" ;;
+  arm64)  arch="arm64" ;;
+  *)      echo "Unsupported architecture" >&2; exit 1 ;;
+esac
+```
+
+### Version Parsing
+
+```bash
+#!/usr/bin/env bash
+
+# Parse semantic version
+parse_version() {
+  local version="$1"
+  # Remove 'v' prefix if present
+  version="${version#v}"
+  echo "$version"
+}
+```
+
+## Testing Plugins
+
+### Local Development
+
+```bash
+# Link plugin for development
+mise plugin add my-plugin /path/to/local/plugin
+
+# Test basic functionality
+mise list-all my-plugin
+mise install my-plugin@1.0.0
+mise which my-plugin
+```
+
+### Debugging
+
+```bash
+# Enable debug mode
+export MISE_DEBUG=1
+
+# Or use --verbose flag
+mise install --verbose my-plugin@1.0.0
+```
+
+## Example Plugin
+
+Here's a minimal example for a fictional tool:
+
+```bash
+#!/usr/bin/env bash
+# bin/list-all
+curl -s "https://api.github.com/repos/example/tool/releases" |
+  grep '"tag_name":' |
+  sed -E 's/.*"v([^"]+)".*/\1/' |
+  sort -V
+```
+
+```bash
+#!/usr/bin/env bash
+# bin/download
+set -e
+version="$ASDF_INSTALL_VERSION"
+platform=$(uname -s | tr '[:upper:]' '[:lower:]')
+arch=$(uname -m)
+
+url="https://github.com/example/tool/releases/download/v${version}/tool-${platform}-${arch}.tar.gz"
+curl -fSL "$url" -o "$ASDF_DOWNLOAD_PATH/tool.tar.gz"
+```
+
+```bash
+#!/usr/bin/env bash
+# bin/install
+set -e
+cd "$ASDF_DOWNLOAD_PATH"
+tar -xzf tool.tar.gz
+cp tool "$ASDF_INSTALL_PATH/bin/"
+chmod +x "$ASDF_INSTALL_PATH/bin/tool"
+```
+
+## Migration Path
+
+Consider migrating from asdf (legacy) plugins to modern alternatives:
+
+1. **Check if tool is available in [aqua registry](https://aquaproj.github.io/aqua-registry/)**
+2. **Use [ubi backend](dev-tools/backends/ubi.md) for simple GitHub releases**
+3. **Create a [mise plugin](plugin-development.md) for complex tools**
+4. **Use language-specific package managers** (npm, pipx, cargo, gem)
+
+## Community Resources
+
+- **[asdf Plugin List](https://github.com/asdf-vm/asdf-plugins)** - Official asdf plugin registry
+- **[mise-plugins Organization](https://github.com/mise-plugins)** - Community-maintained plugins
+- **[Plugin Template](https://github.com/asdf-vm/asdf-plugin-template)** - Template for creating new plugins
+
+## Security Considerations
+
+asdf (legacy) plugins execute arbitrary shell scripts, which poses security risks:
+
+- **Only install plugins from trusted sources**
+- **Review plugin code before installation**
+- **Avoid plugins with complex installation scripts when possible**
+- **Consider using modern backends for better security**
+
+## Next Steps

+# Plugin Development
+
+This guide shows how to create plugins for mise using the extended vfox plugin system. These plugins can manage multiple tools using the `plugin:tool` format, making them perfect for package managers, tool families, and custom installations.
+
+## Plugin Architecture
+
+Plugins in mise use an extended version of the vfox plugin system with enhanced backend methods. Here's the architecture overview:
+
+```mermaid

+```
+
+## Backend Methods vs Traditional Methods
+
+The new backend methods (CamelCase) provide better performance and are preferred for the `plugin:tool` format:
+
+- **BackendListVersions**: List available versions for a tool
+- **BackendInstall**: Install a specific version of a tool
+- **BackendExecEnv**: Set up environment variables for a tool
+
+## Creating a Plugin
+
+### 1. Plugin Structure
+
+Create a directory for your plugin with the following structure:
+
+```
+my-plugin/
+├── metadata.lua          # Plugin metadata and backend methods
+├── README.md            # Plugin documentation
+└── LICENSE              # Plugin license
+```
+
+### 2. metadata.lua
+
+This is the main plugin file that defines metadata and backend methods:
+
+```lua
+PLUGIN = {
+    name = "my-plugin",
+    version = "1.0.0",
+    description = "Description of your plugin",
+    author = "Your Name",
+    license = "MIT",
+    
+    -- Backend method for listing versions
+    BackendListVersions = function(ctx)
+        local tool = BACKEND_CTX.tool
+        local versions = {}
+        
+        -- Your logic to fetch versions for the tool
+        -- Example: query an API, parse a registry, etc.
+        
+        return {versions = versions}
+    end,
+    
+    -- Backend method for installing a tool
+    BackendInstall = function(ctx)
+        local tool = BACKEND_CTX.tool
+        local version = BACKEND_CTX.version
+        local install_path = BACKEND_CTX.install_path
+        
+        -- Your logic to install the tool
+        -- Example: download files, extract archives, etc.
+        
+        return {}
+    end,
+    
+    -- Backend method for setting environment
+    BackendExecEnv = function(ctx)
+        local install_path = BACKEND_CTX.install_path
+        
+        -- Your logic to set up environment variables
+        -- Example: add bin directories to PATH
+        
+        return {
+            env_vars = {
+                {key = "PATH", value = install_path .. "/bin"}
+            }
+        }
+    end
+}
+```
+
+### 3. Available Lua Modules
+
+Your plugin can use these built-in Lua modules:
+
+#### Core Modules
+- `cmd` - Execute shell commands
+- `json` - Parse and generate JSON
+- `http` - Make HTTP requests
+- `file` - File operations
+- `env` - Environment variable operations
+- `strings` - String manipulation
+
+#### HTTP Module
+```lua
+local http = require("http")
+
+-- GET request
+local resp, err = http.get({
+    url = "https://api.github.com/repos/owner/repo/releases",
+    headers = {
+        ['User-Agent'] = "mise-plugin"
+    }
+})
+assert(err == nil)
+assert(resp.status_code == 200)
+local body = resp.body
+
+-- HEAD request
+resp, err = http.head({
+    url = "https://example.com/file.tar.gz"
+})
+assert(err == nil)
+local size = resp.content_length
+
+-- Download file
+err = http.download_file({
+    url = "https://github.com/owner/repo/archive/v1.0.0.tar.gz",
+    headers = {}
+}, "/path/to/download.tar.gz")
+assert(err == nil)
+```
+
+#### JSON Module
+```lua
+local json = require("json")
+
+-- Encode/decode JSON
+local obj = { "a", 1, "b", 2, "c", 3 }
+local jsonStr = json.encode(obj)
+local jsonObj = json.decode(jsonStr)
+```
+
+#### Strings Module
+```lua
+local strings = require("vfox.strings")
+
+-- String manipulation
+local parts = strings.split("hello world", " ")
+print(parts[1]) -- "hello"
+
+assert(strings.has_prefix("hello world", "hello"))
+assert(strings.has_suffix("hello world", "world"))
+assert(strings.trim("hello world", "world") == "hello ")
+assert(strings.contains("hello world", "hello "))
+
+local trimmed = strings.trim_space("  hello  ") -- "hello"
+local joined = strings.join({"1", "3", "4"}, ";") -- "1;3;4"
+```
+
+#### HTML Module
+```lua
+local html = require("html")
+
+-- Parse HTML and extract information
+local doc = html.parse("<html><body><div id='version'>1.2.3</div></body></html>")
+local version = doc:find("#version"):text() -- "1.2.3"
+```
+
+#### Archiver Module
+```lua
+local archiver = require("vfox.archiver")
+
+-- Decompress files (supports tar.gz, tgz, tar.xz, zip, 7z)
+local err = archiver.decompress("archive.zip", "extracted/")
+assert(err == nil)
+```
+
+## Example: npm Package Plugin
+
+Here's a complete example of a plugin that installs npm packages:
+
+```lua
+PLUGIN = {
+    name = "vfox-npm",
+    version = "1.0.0", 
+    description = "mise plugin for npm packages",
+    author = "Your Name",
+    license = "MIT",
+    
+    -- Backend method to list versions
+    BackendListVersions = function(ctx)
+        local tool = BACKEND_CTX.tool
+        local versions = {}
+        
+        -- Use npm view to get real versions
+        local cmd = require("cmd")
+        local result = cmd.exec("npm view " .. tool .. " versions --json 2>/dev/null")
+        
+        if result and result ~= "" and not result:match("npm ERR!") then
+            -- Parse JSON response from npm
+            local json = require("json")
+            local success, npm_versions = pcall(json.decode, result)
+            
+            if success and npm_versions then
+                if type(npm_versions) == "table" then
+                    for i = #npm_versions, 1, -1 do
+                        local version = npm_versions[i]
+                        table.insert(versions, version)
+                    end
+                end
+            end
+        end
+        
+        if #versions == 0 then
+            error("Failed to fetch versions for " .. tool .. " from npm registry")
+        end
+        
+        return {versions = versions}
+    end,

+        
+        -- Install the package using npm
+        local cmd = require("cmd")
+        local npm_cmd = "cd " .. install_path .. " && npm install " .. tool .. "@" .. version .. " --no-package-lock --no-save --silent 2>/dev/null"
+        local result = cmd.exec(npm_cmd)
+        
+        return {}
+    end,
+    
+    -- Backend method to set environment
+    BackendExecEnv = function(ctx)
+        local install_path = BACKEND_CTX.install_path
+        if install_path then
+            -- Add node_modules/.bin to PATH for npm-installed binaries
+            local bin_path = install_path .. "/node_modules/.bin"
+            return {
+                env_vars = {
+                    {key = "PATH", value = bin_path}
+                }
+            }
+        else
+            return {env_vars = {}}
+        end
+    end
+}
+```
+
+## Context Variables
+
+The `BACKEND_CTX` variable provides access to the current operation context:
+
+- `BACKEND_CTX.tool` - The tool name (e.g., "prettier" in "vfox-npm:prettier")
+- `BACKEND_CTX.version` - The requested version (e.g., "3.0.0")
+- `BACKEND_CTX.install_path` - The installation path
+- `BACKEND_CTX.args` - Additional arguments (usually empty)
+

+```
+
+### 2. Automated Testing
+
+Create a test script in your plugin repository:
+
+```bash
+#!/bin/bash
+set -e
+
+# Install the plugin
+mise plugin install my-plugin .
+
+# Test basic functionality
+mise install my-plugin:test-tool@1.0.0
+mise exec my-plugin:test-tool -- --version
+
+# Clean up
+mise plugin remove my-plugin
+```
+
+## Best Practices
+
+### Error Handling
+
+```lua
+-- Always check for errors and provide meaningful messages
+local result = cmd.exec("some-command")
+if not result or result:match("error") then
+    error("Command failed: " .. (result or "no output"))
+end
+```
+
+### Version Parsing
+
+```lua
+-- Parse versions consistently
+local function parse_version(version_string)
+    -- Remove prefixes like 'v' or 'release-'
+    return version_string:gsub("^v?", "")
+end
+```
+
+### Path Handling
+
+```lua
+-- Use proper path separators
+local function join_path(...)
+    local sep = package.config:sub(1,1) -- Get OS path separator
+    return table.concat({...}, sep)
+end
+```
+
+### Cross-Platform Compatibility
+
+```lua
+-- Use cross-platform commands when possible
+local function is_windows()
+    return package.config:sub(1,1) == '\\'
+end
+
+local mkdir_cmd = is_windows() and "mkdir" or "mkdir -p"
+```
+
+## Publishing Your Plugin
+
+### 1. Repository Setup
+
+Create a Git repository with:
+
+```

+
+```lua
+PLUGIN = {
+    name = "github-release",
+    version = "1.0.0",
+    
+    BackendListVersions = function(ctx)
+        local tool = BACKEND_CTX.tool
+        local http = require("http")
+        
+        -- Parse tool as "owner/repo"
+        local owner, repo = tool:match("([^/]+)/([^/]+)")
+        if not owner or not repo then
+            error("Tool must be in format 'owner/repo'")
+        end
+        
+        local url = "https://api.github.com/repos/" .. owner .. "/" .. repo .. "/releases"
+        local response = http.get(url)
+        
+        local json = require("json")
+        local releases = json.decode(response.body)
+        
+        local versions = {}
+        for _, release in ipairs(releases) do
+            if not release.prerelease then
+                table.insert(versions, release.tag_name)
+            end
+        end
+        
+        return {versions = versions}
+    end,
+    
+    BackendInstall = function(ctx)
+        -- Implementation for downloading and installing from GitHub releases
+        -- This would involve finding the right asset, downloading, and extracting
+        return {}
+    end,
+    
+    BackendExecEnv = function(ctx)
+        local install_path = BACKEND_CTX.install_path
+        return {
+            env_vars = {
+                {key = "PATH", value = install_path .. "/bin"}
+            }
+        }
+    end
+}
+```
+
+## Advanced Features
+
+### Custom Configuration
+
+```lua
+-- Access mise.toml configuration
+local config = mise.config()
+local custom_setting = config.plugins["my-plugin"].custom_setting
+```
+
+### Conditional Installation
+
+```lua
+BackendInstall = function(ctx)
+    local tool = BACKEND_CTX.tool
+    local version = BACKEND_CTX.version
+    
+    -- Different installation logic based on tool or version
+    if tool == "special-tool" then
+        -- Special installation logic
+    else
+        -- Default installation logic
+    end
+    
+    return {}
+end
+```
+
+### Environment Detection
+
+```lua
+-- Detect operating system and architecture
+local function get_platform()
+    local cmd = require("cmd")
+    local uname = cmd.exec("uname -s"):lower()
+    local arch = cmd.exec("uname -m")
+    
+    return {os = uname, arch = arch}
+end
+```
+
+## Traditional Plugin Development
+
+In addition to the enhanced backend methods, you can also create traditional plugins that are compatible with the standard vfox ecosystem. These plugins use hook functions and are perfect when you want broader compatibility.
+
+### Hook-Based Plugin Structure
+
+Traditional plugins use a hook-based architecture:
+
+```
+my-plugin/
+├── metadata.lua          # Plugin metadata and configuration
+├── hooks/               # Hook functions directory
+│   ├── available.lua    # List available versions [required]
+│   ├── pre_install.lua  # Pre-installation hook [required]
+│   ├── env_keys.lua     # Environment configuration [required]

+│   └── pre_uninstall.lua # Pre-uninstall hook [optional]
+├── lib/                 # Shared library code [optional]
+└── README.md
+```
+
+### Required Hook Functions
+
+#### Available Hook
+Lists all available versions of the tool:
+
+```lua
+-- hooks/available.lua
+function PLUGIN:Available(ctx)
+    local args = ctx.args  -- User arguments
+    
+    -- Return array of available versions
+    return {
+        {
+            version = "3.0.0",
+            note = "Latest"
+        },
+        {
+            version = "2.9.0",
+            note = "LTS",
+            addition = {
+                {
+                    name = "bundled-tool",
+                    version = "1.2.3"
+                }
+            }
+        }
+    }
+end
+```
+
+#### PreInstall Hook
+Handles pre-installation logic and returns download information:
+
+```lua
+-- hooks/pre_install.lua
+function PLUGIN:PreInstall(ctx)
+    local version = ctx.version
+    local runtimeVersion = ctx.runtimeVersion
+    
+    -- Determine download URL and checksums
+    local url = "https://github.com/owner/repo/releases/download/v" .. version .. "/tool-" .. version .. ".tar.gz"
+    
+    return {
+        version = version,
+        url = url,
+        sha256 = "abc123...",  -- Optional checksum
+        note = "Installing " .. version,
+        -- Additional files can be specified
+        addition = {
+            {
+                name = "extra-file",
+                url = "https://example.com/extra.zip"
+            }
+        }
+    }
+end
+```
+
+#### EnvKeys Hook
+Configures environment variables for the installed tool:
+
+```lua
+-- hooks/env_keys.lua
+function PLUGIN:EnvKeys(ctx)
+    local mainPath = ctx.path
+    local runtimeVersion = ctx.runtimeVersion
+    local sdkInfo = ctx.sdkInfo['tool-name']
+    local path = sdkInfo.path
+    local version = sdkInfo.version
+    local name = sdkInfo.name
+    
+    return {
+        {
+            key = "TOOL_HOME",
+            value = mainPath
+        },
+        {
+            key = "PATH",
+            value = mainPath .. "/bin"
+        },
+        -- Multiple PATH entries are automatically merged
+        {
+            key = "PATH", 
+            value = mainPath .. "/scripts"
+        }
+    }
+end
+```
+
+### Optional Hook Functions
+
+#### PostInstall Hook
+Performs additional setup after installation:
+
+```lua
+-- hooks/post_install.lua
+function PLUGIN:PostInstall(ctx)
+    local rootPath = ctx.rootPath
+    local runtimeVersion = ctx.runtimeVersion
+    local sdkInfo = ctx.sdkInfo['tool-name']
+    local path = sdkInfo.path
+    local version = sdkInfo.version
+    
+    -- Compile source code, set permissions, etc.
+    local cmd = require("cmd")
+    cmd.exec("chmod +x " .. path .. "/bin/*")
+    
+    -- No return value needed
+end
+```
+
+#### PreUse Hook
+Modifies version before use:
+
+```lua
+-- hooks/pre_use.lua
+function PLUGIN:PreUse(ctx)
+    local runtimeVersion = ctx.runtimeVersion
+    local version = ctx.version
+    local previousVersion = ctx.previousVersion
+    local installedSdks = ctx.installedSdks
+    local cwd = ctx.cwd
+    local scope = ctx.scope  -- global/project/session
+    
+    -- Optionally modify the version
+    if version == "latest" then
+        version = "3.0.0"  -- Resolve to specific version
+    end
+    
+    return {
+        version = version
+    }
+end
+```
+
+#### ParseLegacyFile Hook
+Parses version files from other tools:
+
+```lua
+-- hooks/parse_legacy_file.lua
+function PLUGIN:ParseLegacyFile(ctx)
+    local filename = ctx.filename
+    local filepath = ctx.filepath
+    local versions = ctx:getInstalledVersions()
+    
+    -- Read and parse the file
+    local file = require("vfox.file")
+    local content = file.read(filepath)
+    local version = content:match("([%d%.]+)")
+    
+    return {
+        version = version
+    }
+end
+```
+
+### Legacy File Support
+
+To support legacy version files, configure them in `metadata.lua`:
+
+```lua
+-- metadata.lua
+PLUGIN = {
+    name = "my-tool",
+    version = "1.0.0",
+    description = "My awesome tool",
+    author = "Your Name",
+    license = "MIT",
+    
+    -- Legacy version files this plugin can parse
+    legacyFilenames = {
+        '.my-tool-version',
+        '.tool-version'
+    }
+}
+```
+
+### Testing Traditional Plugins
+
+Test your plugin hooks individually:
+
+```bash
+# Test available versions
+mise search my-plugin
+
+# Test pre-install
+mise install my-plugin@1.0.0
+
+# Test env keys
+mise use my-plugin@1.0.0
+echo $TOOL_HOME
+
+# Test with debug output
+mise --debug install my-plugin@1.0.0
+```
+
+## Enhanced Backend Methods vs Traditional Hooks
+
+mise supports both approaches - choose based on your needs:
+
+### Use Enhanced Backend Methods When:
+- Creating plugins specifically for mise
+- Need the `plugin:tool` format for multiple tools
+- Want better performance
+- Building new plugins from scratch
+
+### Use Traditional Hooks When:
+- Need compatibility with standard vfox
+- Porting existing vfox plugins
+- Want to support both mise and vfox users
+- Need complex installation logic
+
+You can even combine both approaches in a single plugin for maximum compatibility.
+
+## vfox Compatibility
+
+mise plugins are built on an extended version of the vfox plugin system. They maintain compatibility with standard vfox plugins while adding enhanced backend methods for better performance and the `plugin:tool` format.
+
+Key differences from standard vfox plugins:
+
+- **Enhanced Backend Methods**: Support for `BackendListVersions`, `BackendInstall`, and `BackendExecEnv`
+- **Plugin:Tool Format**: Ability to manage multiple tools with one plugin
+- **Cross-Platform Support**: Works on Windows, macOS, and Linux
+- **Extended Lua Modules**: Additional built-in modules for common operations
+- **Traditional Hook Support**: Full compatibility with standard vfox hook functions
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Plugin not found**: Ensure the plugin is properly linked or installed
+2. **Tool installation fails**: Check network connectivity and permissions
+3. **Environment variables not set**: Verify BackendExecEnv returns correct format
+4. **Version parsing errors**: Ensure version strings are properly formatted
+
+### Debugging
+
+```lua
+-- Add logging to your plugin
+local function log(message)
+    print("[my-plugin] " .. message)
+end
+
+log("Installing tool: " .. BACKEND_CTX.tool)
+```

+# Using Plugins
+
+mise supports plugins that extend its functionality, allowing you to install tools that aren't available in the standard registry. This is particularly useful for:
+
+- Installing tools from private repositories
+- Using experimental or niche tools
+- Creating custom tool installations for your team
+
+## What Are Plugins?
+
+Plugins are extensions that can install and manage tools not included in mise's built-in registry. They are written in Lua and can:
+
+- Install tools from any source (npm packages, GitHub releases, custom builds)
+- Set up environment variables and PATH entries
+- Handle version management and listing
+- Work across all platforms (Windows, macOS, Linux)
+
+## Installing Plugins
+
+### From a Git Repository
+
+```bash
+# Install a plugin from a repository
+mise plugin install <plugin-name> <repository-url>
+
+# Example: Installing the vfox-npm plugin
+mise plugin install vfox-npm https://github.com/jdx/vfox-npm
+```
+
+### From Local Directory
+
+```bash
+# Link a local plugin for development
+mise plugin link <plugin-name> /path/to/plugin/directory
+```
+
+## Using Plugins
+
+Once a plugin is installed, you can use it with the `plugin:tool` format:
+
+```bash
+# Install a specific tool using the plugin
+mise install vfox-npm:prettier@latest
+
+# Use the tool
+mise use vfox-npm:prettier@3.0.0
+
+# Execute the tool
+mise exec vfox-npm:prettier -- --version
+
+# List available versions
+mise ls-remote vfox-npm:prettier
+```
+
+## Plugin:Tool Format
+
+The `plugin:tool` format allows a single plugin to manage multiple tools. This is particularly useful for:
+
+- **Package managers**: Install different npm packages, Python packages, etc.
+- **Tool families**: Manage related tools from the same ecosystem
+- **Custom builds**: Install different variants of the same tool
+
+### Example: npm packages
+
+```bash
+# Install different npm packages using the same plugin
+mise install vfox-npm:prettier@latest
+mise install vfox-npm:eslint@8.0.0
+mise install vfox-npm:typescript@latest
+
+# Use them in your project
+mise use vfox-npm:prettier@latest vfox-npm:eslint@8.0.0
+```
+
+## Managing Plugins
+
+### List installed plugins
+
+```bash
+# Show all plugins
+mise plugins ls
+
+# Show plugin URLs
+mise plugins ls --urls
+```
+
+### Update plugins
+
+```bash
+# Update a specific plugin
+mise plugin update vfox-npm
+
+# Update all plugins
+mise plugin update --all
+```
+
+### Remove plugins
+
+```bash
+# Remove a plugin
+mise plugin remove vfox-npm
+
+# This will also remove all tools installed by the plugin
+```
+
+## Configuration
+
+Plugins can be configured in your `mise.toml` file:
+
+```toml
+[plugins]
+vfox-npm = "https://github.com/jdx/vfox-npm"
+
+[tools]
+"vfox-npm:prettier" = "latest"
+"vfox-npm:eslint" = "8.0.0"
+```
+
+## Finding Plugins
+
+While mise doesn't have a centralized registry for community plugins, you can find them:
+
+- **GitHub**: Search for repositories with "vfox-" prefix
+- **Community**: Check mise community discussions and Discord
+- **Company internal**: Your organization may have private plugins
+
+## Plugin Examples
+
+### vfox-npm (Example Plugin)
+
+The `vfox-npm` plugin demonstrates how to create a plugin that installs npm packages:
+
+```bash
+# Install the plugin
+mise plugin install vfox-npm https://github.com/jdx/vfox-npm
+
+# Install tools
+mise install vfox-npm:prettier@latest
+mise install vfox-npm:eslint@latest
+
+# Use them
+mise use vfox-npm:prettier@latest
+mise exec vfox-npm:prettier -- --check .
+```
+
+**Note**: This is just an example plugin for testing. mise already has built-in npm support that you should use instead: `mise install npm:prettier@latest`
+
+## How Plugins Work
+
+Plugins in mise are built on an extended version of the vfox plugin system. They use enhanced backend methods that provide better performance and support for the `plugin:tool` format:
+
+- **BackendListVersions**: Lists available versions of a tool
+- **BackendInstall**: Installs a specific version
+- **BackendExecEnv**: Sets up environment variables
+
+This architecture allows plugins to manage multiple tools efficiently while providing a consistent interface.
+
+## Security Considerations
+
+When using plugins, be aware that:
+
+- **Plugins execute arbitrary code** during installation and use
+- **Only install plugins from trusted sources**
+- **Review plugin code** before installation when possible
+- **Use version pinning** to avoid unexpected updates
+
+## Troubleshooting
+
+### Plugin installation fails
+
+```bash
+# Check if the repository URL is correct
+mise plugin install vfox-npm https://github.com/jdx/vfox-npm
+
+# Check plugin directory
+ls ~/.local/share/mise/plugins/
+```
+
+### Tool installation fails
+
+```bash
+# Check plugin logs
+mise install vfox-npm:prettier@latest --verbose
+
+# Verify plugin is installed
+mise plugins ls
+```
+
+### Environment issues
+
+```bash
+# Check if PATH is set correctly
+mise exec vfox-npm:prettier env | grep PATH
+
+# Verify tool is installed
+ls ~/.local/share/mise/installs/vfox-npm/prettier/
+```

+# Backend Plugin Development
+
+Backend plugins in mise use enhanced backend methods to manage multiple tools using the `plugin:tool` format. These plugins are perfect for package managers, tool families, and custom installations that need to manage multiple related tools.
+
+## What are Backend Plugins?
+
+Backend plugins extend the standard vfox plugin system with enhanced backend methods. They support:
+
+- **Multiple Tools**: One plugin can manage multiple tools (e.g., `vfox-npm:prettier`, `vfox-npm:eslint`)
+- **Enhanced Performance**: Optimized backend methods for better performance
+- **Cross-Platform Support**: Works on Windows, macOS, and Linux
+- **Modern Architecture**: CamelCase method names and structured responses
+
+## Plugin Architecture
+
+Backend plugins use three main methods:

+    style F fill:#e8f5e8
+```
+
+## Backend Methods
+
+### BackendListVersions
+
+Lists available versions for a tool:
+
+```lua
+BackendListVersions = function(ctx)
+    local tool = BACKEND_CTX.tool
+    local versions = {}
+    
+    -- Your logic to fetch versions for the tool
+    -- Example: query an API, parse a registry, etc.
+    
+    return {versions = versions}
+end
+```
+
+### BackendInstall
+
+Installs a specific version of a tool:
+
+```lua
+BackendInstall = function(ctx)
+    local tool = BACKEND_CTX.tool
+    local version = BACKEND_CTX.version
+    local install_path = BACKEND_CTX.install_path
+    
+    -- Your logic to install the tool
+    -- Example: download files, extract archives, etc.
+    
+    return {}
+end
+```
+
+### BackendExecEnv
+
+Sets up environment variables for a tool:
+
+```lua
+BackendExecEnv = function(ctx)
+    local install_path = BACKEND_CTX.install_path
+    
+    -- Your logic to set up environment variables
+    -- Example: add bin directories to PATH
+    
+    return {
+        env_vars = {
+            {key = "PATH", value = install_path .. "/bin"}
+        }
+    }
+end
+```
+
+## Creating a Backend Plugin
+
+### 1. Plugin Structure
+
+Create a directory with this structure:
+
+```
+vfox-npm/
+├── metadata.lua          # Plugin metadata and backend methods
+└── test/                 # Test scripts (optional)
+    └── test.sh
+```
+
+### 2. Basic metadata.lua
+
+```lua
+PLUGIN = {
+    name = "vfox-npm",
+    version = "1.0.0",
+    description = "Backend plugin for npm packages",
+    author = "Your Name",
+    
+    -- Backend method for listing versions
+    BackendListVersions = function(ctx)
+        -- Implementation here
+    end,
+    
+    -- Backend method for installing a tool
+    BackendInstall = function(ctx)
+        -- Implementation here
+    end,
+    
+    -- Backend method for setting environment
+    BackendExecEnv = function(ctx)
+        -- Implementation here
+    end
+}
+```
+
+## Real-World Example: vfox-npm
+
+Here's the complete implementation of the vfox-npm plugin that manages npm packages:
+
+```lua
+PLUGIN = {
+    name = "vfox-npm",
+    version = "1.0.0", 
+    description = "Backend plugin for npm packages",
+    author = "jdx",
+    
+    -- Backend method to list versions
+    BackendListVersions = function(ctx)
+        local tool = BACKEND_CTX.tool
+        local versions = {}
+        
+        -- Use npm view to get real versions
+        local result = os.capture("npm view " .. tool .. " versions --json 2>/dev/null")
+        
+        if result and result ~= "" and not result:match("npm ERR!") then
+            -- Parse JSON response from npm
+            local json = require("json")
+            local success, npm_versions = pcall(json.decode, result)
+            
+            if success and npm_versions then
+                if type(npm_versions) == "table" then
+                    for i = #npm_versions, 1, -1 do
+                        local version = npm_versions[i]
+                        table.insert(versions, version)
+                    end
+                end
+            end
+        end
+        
+        if #versions == 0 then
+            error("Failed to fetch versions for " .. tool .. " from npm registry")
+        end
+        
+        return {versions = versions}
+    end,
+    
+    -- Backend method to install a tool
+    BackendInstall = function(ctx)
+        local tool = BACKEND_CTX.tool
+        local version = BACKEND_CTX.version
+        local install_path = BACKEND_CTX.install_path
+        
+        -- Create install directory
+        os.execute("mkdir -p " .. install_path)
+        
+        -- Install the package using npm
+        local npm_cmd = "cd " .. install_path .. " && npm install " .. tool .. "@" .. version .. " --no-package-lock --no-save --silent 2>/dev/null"
+        local result = os.execute(npm_cmd)
+        
+        if result ~= 0 then
+            error("Failed to install " .. tool .. "@" .. version)
+        end
+        
+        return {}
+    end,
+    
+    -- Backend method to set environment
+    BackendExecEnv = function(ctx)
+        local install_path = BACKEND_CTX.install_path
+        if install_path then
+            -- Add node_modules/.bin to PATH for npm-installed binaries
+            local bin_path = install_path .. "/node_modules/.bin"
+            return {
+                env_vars = {
+                    {key = "PATH", value = bin_path}
+                }
+            }
+        else
+            return {env_vars = {}}
+        end
+    end
+}
+
+-- Helper function to capture command output
+function os.capture(cmd, raw)
+    local f = assert(io.popen(cmd, 'r'))
+    local s = assert(f:read('*a'))
+    f:close()
+    if raw then return s end
+    s = string.gsub(s, '^%s+', '')
+    s = string.gsub(s, '%s+$', '')
+    s = string.gsub(s, '[\n\r]+', ' ')
+    return s
+end
+```
+
+## Usage Example
+
+With the vfox-npm plugin installed, you can manage npm packages:
+
+```bash
+# Install the plugin
+mise plugin install vfox-npm https://github.com/jdx/vfox-npm
+
+# List available versions
+mise ls-remote vfox-npm:prettier
+
+# Install a specific version
+mise install vfox-npm:prettier@3.0.0
+
+# Use in a project
+mise use vfox-npm:prettier@latest
+
+# Execute the tool
+mise exec vfox-npm:prettier -- --help
+```
+
+## Context Variables
+
+Backend plugins receive context through the `BACKEND_CTX` variable:
+
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `BACKEND_CTX.tool` | The tool name | `"prettier"` |
+| `BACKEND_CTX.version` | The requested version | `"3.0.0"` |
+| `BACKEND_CTX.install_path` | Installation directory | `"/home/user/.local/share/mise/installs/vfox-npm/prettier/3.0.0"` |
+| `BACKEND_CTX.args` | Additional arguments | `[]` (usually empty) |
+
+## Testing Your Plugin
+
+### Local Development
+
+```bash
+# Link your plugin for development
+mise plugin link my-plugin /path/to/my-plugin
+
+# Test listing versions
+mise ls-remote my-plugin:some-tool
+
+# Test installation
+mise install my-plugin:some-tool@1.0.0
+
+# Test execution
+mise exec my-plugin:some-tool -- --version
+```
+
+### Debug Mode
+
+Use debug mode to see detailed plugin execution:
+
+```bash
+mise --debug install my-plugin:some-tool@1.0.0
+```
+
+## Best Practices
+
+### Error Handling
+
+Always provide meaningful error messages:
+
+```lua
+BackendListVersions = function(ctx)
+    local tool = BACKEND_CTX.tool
+    
+    -- Validate tool name
+    if not tool or tool == "" then
+        error("Tool name cannot be empty")
+    end
+    
+    -- Execute command with error checking
+    local result = os.capture("some-command")
+    if not result or result:match("error") then
+        error("Failed to fetch versions for " .. tool .. ": " .. (result or "no output"))
+    end
+    
+    -- Return versions or error if none found
+    local versions = parse_versions(result)
+    if #versions == 0 then
+        error("No versions found for " .. tool)
+    end
+    
+    return {versions = versions}
+end
+```
+
+### Version Parsing
+
+Parse versions consistently:
+
+```lua
+local function parse_version(version_string)
+    -- Remove prefixes like 'v' or 'release-'
+    return version_string:gsub("^[vr]?", ""):gsub("^release%-", "")
+end
+```
+
+### Path Handling
+
+Use cross-platform path handling:
+
+```lua
+local function join_path(...)
+    local sep = package.config:sub(1,1) -- Get OS path separator
+    return table.concat({...}, sep)
+end
+
+local bin_path = join_path(install_path, "bin")
+```
+
+### Cross-Platform Commands
+
+Handle different operating systems:
+
+```lua
+local function is_windows()
+    return package.config:sub(1,1) == '\\'
+end
+
+local function create_dir(path)
+    local cmd = is_windows() and "mkdir" or "mkdir -p"
+    os.execute(cmd .. " " .. path)
+end
+```
+
+## Advanced Features
+
+### Conditional Installation
+
+Different installation logic based on tool or version:
+
+```lua
+BackendInstall = function(ctx)
+    local tool = BACKEND_CTX.tool
+    local version = BACKEND_CTX.version
+    
+    if tool == "special-tool" then
+        -- Special installation logic
+        install_special_tool(version)
+    else
+        -- Default installation logic
+        install_default_tool(tool, version)
+    end
+    
+    return {}
+end
+```
+
+### Environment Detection
+
+Detect operating system and architecture:
+
+```lua
+local function get_platform()
+    local uname = os.capture("uname -s"):lower()
+    local arch = os.capture("uname -m")
+    return {os = uname, arch = arch}
+end
+
+BackendInstall = function(ctx)
+    local platform = get_platform()
+    local tool = BACKEND_CTX.tool
+    local version = BACKEND_CTX.version
+    
+    -- Platform-specific installation
+    if platform.os == "darwin" then
+        -- macOS installation
+    elseif platform.os == "linux" then
+        -- Linux installation
+    else
+        -- Other platforms
+    end
+    
+    return {}
+end
+```
+
+### Multiple Environment Variables
+
+Set multiple environment variables:
+
+```lua
+BackendExecEnv = function(ctx)
+    local install_path = BACKEND_CTX.install_path
+    local tool = BACKEND_CTX.tool
+    
+    return {
+        env_vars = {
+            {key = "PATH", value = install_path .. "/bin"},
+            {key = "PATH", value = install_path .. "/scripts"},
+            {key = tool:upper() .. "_HOME", value = install_path},
+            {key = tool:upper() .. "_VERSION", value = BACKEND_CTX.version}
+        }
+    }
+end
+```
+
+## Performance Optimization
+
+### Caching
+
+Cache expensive operations when possible:
+
+```lua
+-- Cache versions for a short time
+local version_cache = {}
+local cache_ttl = 300 -- 5 minutes
+
+BackendListVersions = function(ctx)
+    local tool = BACKEND_CTX.tool
+    local now = os.time()
+    
+    -- Check cache first
+    if version_cache[tool] and (now - version_cache[tool].timestamp) < cache_ttl then
+        return {versions = version_cache[tool].versions}
+    end
+    
+    -- Fetch versions
+    local versions = fetch_versions(tool)
+    
+    -- Cache the result

+        timestamp = now
+    }
+    
+    return {versions = versions}
+end
+```
+
+### Parallel Downloads
+
+For plugins that need to download multiple files:
+
+```lua
+BackendInstall = function(ctx)
+    local tool = BACKEND_CTX.tool
+    local version = BACKEND_CTX.version
+    local install_path = BACKEND_CTX.install_path
+    
+    -- Download files in parallel when possible
+    local downloads = {
+        {url = "https://example.com/file1.zip", dest = install_path .. "/file1.zip"},
+        {url = "https://example.com/file2.zip", dest = install_path .. "/file2.zip"}
+    }
+    
+    -- Use parallel downloads if available
+    parallel_download(downloads)
+    
+    return {}
+end

-# Plugin Development
-
-This guide shows how to create plugins for mise using the extended vfox plugin system. These plugins can manage multiple tools using the `plugin:tool` format, making them perfect for package managers, tool families, and custom installations.
-
-## Plugin Architecture
-
-Plugins in mise use an extended version of the vfox plugin system with enhanced backend methods. Here's the architecture overview:

-
-## Backend Methods vs Traditional Methods
-
-The new backend methods (CamelCase) provide better performance and are preferred for the `plugin:tool` format:
-
-- **BackendListVersions**: List available versions for a tool
-- **BackendInstall**: Install a specific version of a tool
-- **BackendExecEnv**: Set up environment variables for a tool
-
-## Creating a Plugin
-
-### 1. Plugin Structure
-
-Create a directory for your plugin with the following structure:
-
-```
-my-plugin/
-├── metadata.lua          # Plugin metadata and backend methods
-├── README.md            # Plugin documentation
-└── LICENSE              # Plugin license
-```
-
-### 2. metadata.lua
-
-This is the main plugin file that defines metadata and backend methods:
-
-```lua
-PLUGIN = {
-    name = "my-plugin",
-    version = "1.0.0",
-    description = "Description of your plugin",
-    author = "Your Name",
-    license = "MIT",
-    
-    -- Backend method for listing versions
-    BackendListVersions = function(ctx)
-        local tool = BACKEND_CTX.tool
-        local versions = {}
-        
-        -- Your logic to fetch versions for the tool
-        -- Example: query an API, parse a registry, etc.
-        
-        return {versions = versions}
-    end,
-    
-    -- Backend method for installing a tool
-    BackendInstall = function(ctx)
-        local tool = BACKEND_CTX.tool
-        local version = BACKEND_CTX.version
-        local install_path = BACKEND_CTX.install_path
-        
-        -- Your logic to install the tool
-        -- Example: download files, extract archives, etc.
-        
-        return {}
-    end,
-    
-    -- Backend method for setting environment
-    BackendExecEnv = function(ctx)
-        local install_path = BACKEND_CTX.install_path
-        
-        -- Your logic to set up environment variables
-        -- Example: add bin directories to PATH
-        
-        return {
-            env_vars = {
-                {key = "PATH", value = install_path .. "/bin"}
-            }
-        }
-    end
-}

-
-### 3. Available Lua Modules
-
-Your plugin can use these built-in Lua modules:
-
-#### Core Modules
-- `cmd` - Execute shell commands
-- `json` - Parse and generate JSON
-- `http` - Make HTTP requests
-- `file` - File operations
-- `env` - Environment variable operations
-- `strings` - String manipulation
-
-#### HTTP Module
-```lua
-local http = require("http")
-
--- GET request
-local resp, err = http.get({
-    url = "https://api.github.com/repos/owner/repo/releases",
-    headers = {
-        ['User-Agent'] = "mise-plugin"
-    }
-})
-assert(err == nil)
-assert(resp.status_code == 200)
-local body = resp.body
-
--- HEAD request
-resp, err = http.head({
-    url = "https://example.com/file.tar.gz"
-})
-assert(err == nil)
-local size = resp.content_length
-
--- Download file
-err = http.download_file({
-    url = "https://github.com/owner/repo/archive/v1.0.0.tar.gz",
-    headers = {}
-}, "/path/to/download.tar.gz")
-assert(err == nil)
-```
-
-#### JSON Module
-```lua
-local json = require("json")
-
--- Encode/decode JSON
-local obj = { "a", 1, "b", 2, "c", 3 }
-local jsonStr = json.encode(obj)
-local jsonObj = json.decode(jsonStr)
-```
-
-#### Strings Module
-```lua
-local strings = require("vfox.strings")
-
--- String manipulation
-local parts = strings.split("hello world", " ")
-print(parts[1]) -- "hello"
-
-assert(strings.has_prefix("hello world", "hello"))
-assert(strings.has_suffix("hello world", "world"))
-assert(strings.trim("hello world", "world") == "hello ")
-assert(strings.contains("hello world", "hello "))
-
-local trimmed = strings.trim_space("  hello  ") -- "hello"
-local joined = strings.join({"1", "3", "4"}, ";") -- "1;3;4"
-```
-
-#### HTML Module
-```lua
-local html = require("html")
-
--- Parse HTML and extract information
-local doc = html.parse("<html><body><div id='version'>1.2.3</div></body></html>")
-local version = doc:find("#version"):text() -- "1.2.3"
-```
-
-#### Archiver Module
-```lua
-local archiver = require("vfox.archiver")
-
--- Decompress files (supports tar.gz, tgz, tar.xz, zip, 7z)
-local err = archiver.decompress("archive.zip", "extracted/")
-assert(err == nil)
-```
-
-## Example: npm Package Plugin
-

-            -- Parse JSON response from npm
-            local json = require("json")
-            local success, npm_versions = pcall(json.decode, result)

-## Context Variables
-
-The `BACKEND_CTX` variable provides access to the current operation context:
-
-- `BACKEND_CTX.tool` - The tool name (e.g., "prettier" in "vfox-npm:prettier")
-- `BACKEND_CTX.version` - The requested version (e.g., "3.0.0")
-- `BACKEND_CTX.install_path` - The installation path
-- `BACKEND_CTX.args` - Additional arguments (usually empty)
-
-## Testing Your Plugin
-
-### 1. Local Development
-
-```bash
-# Link your plugin for development
-mise plugin link my-plugin /path/to/my-plugin
-
-# Test listing versions
-mise ls-remote my-plugin:some-tool
-
-# Test installation
-mise install my-plugin:some-tool@1.0.0
-
-# Test execution
-mise exec my-plugin:some-tool -- --version
-```
-
-### 2. Automated Testing
-
-Create a test script in your plugin repository:
-
-```bash
-#!/bin/bash
-set -e
-
-# Install the plugin
-mise plugin install my-plugin .
-
-# Test basic functionality
-mise install my-plugin:test-tool@1.0.0
-mise exec my-plugin:test-tool -- --version
-
-# Clean up
-mise plugin remove my-plugin
-```

-```lua
--- Always check for errors and provide meaningful messages
-local result = cmd.exec("some-command")
-if not result or result:match("error") then
-    error("Command failed: " .. (result or "no output"))
-end
-```
-
-### Version Parsing
-
-```lua
--- Parse versions consistently
-local function parse_version(version_string)
-    -- Remove prefixes like 'v' or 'release-'
-    return version_string:gsub("^v?", "")
-end
-```
-
-### Path Handling
-
-```lua
--- Use proper path separators
-local function join_path(...)
-    local sep = package.config:sub(1,1) -- Get OS path separator
-    return table.concat({...}, sep)
-end
-```
-
-### Cross-Platform Compatibility
-
-```lua
--- Use cross-platform commands when possible
-local function is_windows()
-    return package.config:sub(1,1) == '\\'
-end
-
-local mkdir_cmd = is_windows() and "mkdir" or "mkdir -p"
-```

-local config = mise.config()
-local custom_setting = config.plugins["my-plugin"].custom_setting
-```
-
-### Conditional Installation
-
-```lua
-BackendInstall = function(ctx)
-    local tool = BACKEND_CTX.tool
-    local version = BACKEND_CTX.version
-    
-    -- Different installation logic based on tool or version
-    if tool == "special-tool" then

-    local arch = cmd.exec("uname -m")
-    
-    return {os = uname, arch = arch}
-end
-```
-
-## Traditional Plugin Development
-
-In addition to the enhanced backend methods, you can also create traditional plugins that are compatible with the standard vfox ecosystem. These plugins use hook functions and are perfect when you want broader compatibility.
-
-### Hook-Based Plugin Structure
-
-Traditional plugins use a hook-based architecture:
-
-```
-my-plugin/
-├── metadata.lua          # Plugin metadata and configuration
-├── hooks/               # Hook functions directory
-│   ├── available.lua    # List available versions [required]
-│   ├── pre_install.lua  # Pre-installation hook [required]
-│   ├── env_keys.lua     # Environment configuration [required]
-│   ├── post_install.lua # Post-installation hook [optional]
-│   ├── pre_use.lua      # Pre-use hook [optional]
-│   ├── parse_legacy_file.lua # Legacy file parser [optional]
-│   └── pre_uninstall.lua # Pre-uninstall hook [optional]
-├── lib/                 # Shared library code [optional]
-└── README.md
-```
-
-### Required Hook Functions
-
-#### Available Hook
-Lists all available versions of the tool:
-
-```lua
--- hooks/available.lua
-function PLUGIN:Available(ctx)
-    local args = ctx.args  -- User arguments
-    
-    -- Return array of available versions
-    return {
-        {
-            version = "3.0.0",
-            note = "Latest"
-        },
-        {
-            version = "2.9.0",
-            note = "LTS",
-            addition = {
-                {
-                    name = "bundled-tool",
-                    version = "1.2.3"
-                }
-            }
-        }
-    }
-end
-```
-
-#### PreInstall Hook
-Handles pre-installation logic and returns download information:
-
-```lua
--- hooks/pre_install.lua
-function PLUGIN:PreInstall(ctx)
-    local version = ctx.version
-    local runtimeVersion = ctx.runtimeVersion
-    
-    -- Determine download URL and checksums
-    local url = "https://github.com/owner/repo/releases/download/v" .. version .. "/tool-" .. version .. ".tar.gz"
-    
-    return {
-        version = version,
-        url = url,
-        sha256 = "abc123...",  -- Optional checksum
-        note = "Installing " .. version,
-        -- Additional files can be specified
-        addition = {
-            {
-                name = "extra-file",
-                url = "https://example.com/extra.zip"
-            }
-        }
-    }
-end
-```
-
-#### EnvKeys Hook
-Configures environment variables for the installed tool:
-
-```lua
--- hooks/env_keys.lua
-function PLUGIN:EnvKeys(ctx)
-    local mainPath = ctx.path
-    local runtimeVersion = ctx.runtimeVersion
-    local sdkInfo = ctx.sdkInfo['tool-name']
-    local path = sdkInfo.path
-    local version = sdkInfo.version
-    local name = sdkInfo.name
-    
-    return {
-        {
-            key = "TOOL_HOME",
-            value = mainPath
-        },
-        {
-            key = "PATH",
-            value = mainPath .. "/bin"
-        },
-        -- Multiple PATH entries are automatically merged
-        {
-            key = "PATH", 
-            value = mainPath .. "/scripts"
-        }
-    }
-end
-```
-
-### Optional Hook Functions
-
-#### PostInstall Hook
-Performs additional setup after installation:
-
-```lua
--- hooks/post_install.lua
-function PLUGIN:PostInstall(ctx)
-    local rootPath = ctx.rootPath
-    local runtimeVersion = ctx.runtimeVersion
-    local sdkInfo = ctx.sdkInfo['tool-name']
-    local path = sdkInfo.path
-    local version = sdkInfo.version
-    
-    -- Compile source code, set permissions, etc.
-    local cmd = require("cmd")
-    cmd.exec("chmod +x " .. path .. "/bin/*")
-    
-    -- No return value needed
-end
-```
-
-#### PreUse Hook
-Modifies version before use:
-
-```lua
--- hooks/pre_use.lua
-function PLUGIN:PreUse(ctx)
-    local runtimeVersion = ctx.runtimeVersion
-    local version = ctx.version
-    local previousVersion = ctx.previousVersion
-    local installedSdks = ctx.installedSdks
-    local cwd = ctx.cwd
-    local scope = ctx.scope  -- global/project/session
-    
-    -- Optionally modify the version
-    if version == "latest" then
-        version = "3.0.0"  -- Resolve to specific version
-    end
-    
-    return {
-        version = version
-    }
-end
-```
-
-#### ParseLegacyFile Hook
-Parses version files from other tools:
-
-```lua
--- hooks/parse_legacy_file.lua
-function PLUGIN:ParseLegacyFile(ctx)
-    local filename = ctx.filename
-    local filepath = ctx.filepath
-    local versions = ctx:getInstalledVersions()
-    
-    -- Read and parse the file
-    local file = require("vfox.file")
-    local content = file.read(filepath)
-    local version = content:match("([%d%.]+)")
-    
-    return {
-        version = version
-    }
-end
-```
-
-### Legacy File Support
-
-To support legacy version files, configure them in `metadata.lua`:
-
-```lua
--- metadata.lua
-PLUGIN = {
-    name = "my-tool",
-    version = "1.0.0",
-    description = "My awesome tool",
-    author = "Your Name",
-    license = "MIT",
-    
-    -- Legacy version files this plugin can parse
-    legacyFilenames = {
-        '.my-tool-version',
-        '.tool-version'
-    }
-}
-```
-
-### Testing Traditional Plugins
-
-Test your plugin hooks individually:
-
-```bash
-# Test available versions
-mise search my-plugin
-
-# Test pre-install
-mise install my-plugin@1.0.0
-
-# Test env keys
-mise use my-plugin@1.0.0
-echo $TOOL_HOME
-
-# Test with debug output
-mise --debug install my-plugin@1.0.0
-```
-
-## Enhanced Backend Methods vs Traditional Hooks
-
-mise supports both approaches - choose based on your needs:
-
-### Use Enhanced Backend Methods When:
-- Creating plugins specifically for mise
-- Need the `plugin:tool` format for multiple tools
-- Want better performance
-- Building new plugins from scratch
-
-### Use Traditional Hooks When:
-- Need compatibility with standard vfox
-- Porting existing vfox plugins
-- Want to support both mise and vfox users
-- Need complex installation logic
-
-You can even combine both approaches in a single plugin for maximum compatibility.
-
-## vfox Compatibility
-
-mise plugins are built on an extended version of the vfox plugin system. They maintain compatibility with standard vfox plugins while adding enhanced backend methods for better performance and the `plugin:tool` format.
-
-Key differences from standard vfox plugins:
-
-- **Enhanced Backend Methods**: Support for `BackendListVersions`, `BackendInstall`, and `BackendExecEnv`
-- **Plugin:Tool Format**: Ability to manage multiple tools with one plugin
-- **Cross-Platform Support**: Works on Windows, macOS, and Linux
-- **Extended Lua Modules**: Additional built-in modules for common operations
-- **Traditional Hook Support**: Full compatibility with standard vfox hook functions
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Plugin not found**: Ensure the plugin is properly linked or installed
-2. **Tool installation fails**: Check network connectivity and permissions
-3. **Environment variables not set**: Verify BackendExecEnv returns correct format
-4. **Version parsing errors**: Ensure version strings are properly formatted
-
-### Debugging
-
-```lua
--- Add logging to your plugin
-local function log(message)
-    print("[my-plugin] " .. message)
-end
-
-log("Installing tool: " .. BACKEND_CTX.tool)
-```

+# Plugin Lua Modules
+
+mise plugins have access to a comprehensive set of built-in Lua modules that provide common functionality. These modules are available in both backend plugins and tool plugins, making it easy to perform common operations like HTTP requests, JSON parsing, file operations, and more.
+
+## Available Modules
+
+### Core Modules
+
+- **`cmd`** - Execute shell commands
+- **`json`** - Parse and generate JSON
+- **`http`** - Make HTTP requests and downloads
+- **`file`** - File system operations
+- **`env`** - Environment variable operations
+- **`strings`** - String manipulation utilities
+- **`html`** - HTML parsing and manipulation
+- **`archiver`** - Archive extraction and compression
+
+## HTTP Module
+
+The HTTP module provides functionality for making web requests and downloading files.
+
+### Basic HTTP Requests
+
+```lua
+local http = require("http")
+
+-- GET request
+local resp, err = http.get({
+    url = "https://api.github.com/repos/owner/repo/releases",
+    headers = {
+        ['User-Agent'] = "mise-plugin",
+        ['Accept'] = "application/json"
+    }
+})
+
+if err ~= nil then
+    error("Request failed: " .. err)
+end
+
+if resp.status_code ~= 200 then
+    error("HTTP error: " .. resp.status_code)
+end
+
+local body = resp.body
+```
+
+### HEAD Requests
+
+```lua
+local http = require("http")
+
+-- HEAD request to check file info
+local resp, err = http.head({
+    url = "https://example.com/file.tar.gz"
+})
+
+if err ~= nil then
+    error("HEAD request failed: " .. err)
+end
+
+local content_length = resp.headers['content-length']
+local content_type = resp.headers['content-type']
+```
+
+### File Downloads
+
+```lua
+local http = require("http")
+
+-- Download file
+local err = http.download_file({
+    url = "https://github.com/owner/repo/archive/v1.0.0.tar.gz",
+    headers = {
+        ['User-Agent'] = "mise-plugin"
+    }
+}, "/path/to/download.tar.gz")
+
+if err ~= nil then
+    error("Download failed: " .. err)
+end
+```
+
+### Response Object
+
+HTTP responses contain the following fields:
+
+```lua
+{
+    status_code = 200,
+    headers = {
+        ['content-type'] = "application/json",
+        ['content-length'] = "1234"
+    },
+    body = "response content"
+}
+```
+
+## JSON Module
+
+The JSON module provides encoding and decoding functionality.
+
+### Basic Usage
+
+```lua
+local json = require("json")
+
+-- Encode table to JSON string
+local obj = {
+    name = "mise-plugin",
+    version = "1.0.0",
+    tools = {"prettier", "eslint"}
+}
+local jsonStr = json.encode(obj)
+-- Result: '{"name":"mise-plugin","version":"1.0.0","tools":["prettier","eslint"]}'
+
+-- Decode JSON string to table
+local decoded = json.decode(jsonStr)
+print(decoded.name)  -- "mise-plugin"
+print(decoded.tools[1])  -- "prettier"
+```
+
+### Error Handling (Lua)
+
+```lua
+local json = require("json")
+
+-- Safe JSON parsing
+local success, result = pcall(json.decode, response_body)
+if not success then
+    error("Failed to parse JSON: " .. result)
+end
+
+-- Use the parsed data
+for _, item in ipairs(result) do
+    print(item.version)
+end
+```
+
+## Strings Module
+
+The strings module provides various string manipulation utilities.
+
+### String Operations
+
+```lua
+local strings = require("vfox.strings")
+
+-- Split string into parts
+local parts = strings.split("hello,world,test", ",")
+print(parts[1])  -- "hello"
+print(parts[2])  -- "world"
+print(parts[3])  -- "test"
+
+-- Join strings
+local joined = strings.join({"hello", "world", "test"}, " - ")
+print(joined)  -- "hello - world - test"
+
+-- Trim whitespace
+local trimmed = strings.trim_space("  hello world  ")
+print(trimmed)  -- "hello world"
+```
+
+### String Checks
+
+```lua
+local strings = require("vfox.strings")
+
+-- Check prefixes and suffixes
+local text = "hello world"
+print(strings.has_prefix(text, "hello"))  -- true
+print(strings.has_suffix(text, "world"))  -- true
+print(strings.contains(text, "lo wo"))    -- true
+
+-- Trim specific characters
+local trimmed = strings.trim("hello world", "world")
+print(trimmed)  -- "hello "
+```
+
+### Version String Utilities
+
+```lua
+local strings = require("vfox.strings")
+
+-- Common version string operations
+local function normalize_version(version)
+    -- Remove 'v' prefix if present
+    version = strings.trim_prefix(version, "v")
+    
+    -- Remove pre-release suffixes
+    local parts = strings.split(version, "-")
+    return parts[1]
+end
+
+local version = normalize_version("v1.2.3-beta.1")  -- "1.2.3"
+```
+
+## HTML Module
+
+The HTML module provides HTML parsing capabilities.
+
+### Basic HTML Parsing
+
+```lua
+local html = require("html")
+
+-- Parse HTML document
+local doc = html.parse([[
+    <html>
+        <body>
+            <div id="version" class="info">1.2.3</div>
+            <ul class="downloads">
+                <li><a href="/download/v1.2.3.tar.gz">Source</a></li>
+                <li><a href="/download/v1.2.3.zip">Windows</a></li>
+            </ul>
+        </body>
+    </html>
+]])
+
+-- Extract text content
+local version = doc:find("#version"):text()  -- "1.2.3"
+
+-- Extract attributes
+local links = doc:find("a")
+for _, link in ipairs(links) do
+    local href = link:attr("href")
+    local text = link:text()
+    print(text .. ": " .. href)
+end
+```
+
+### CSS Selectors
+
+```lua
+local html = require("html")
+
+local doc = html.parse(html_content)
+
+-- Find by ID
+local element = doc:find("#version")
+
+-- Find by class
+local elements = doc:find(".download-link")
+
+-- Find by tag
+local links = doc:find("a")
+
+-- Complex selectors
+local specific_links = doc:find("ul.downloads a[href$='.tar.gz']")
+```
+
+### Real-World Example: Scraping Releases
+
+```lua
+local html = require("html")
+local http = require("http")
+
+function get_github_releases(owner, repo)
+    local resp, err = http.get({
+        url = "https://github.com/" .. owner .. "/" .. repo .. "/releases"
+    })
+    
+    if err ~= nil then
+        error("Failed to fetch releases: " .. err)
+    end
+    
+    local doc = html.parse(resp.body)
+    local releases = {}
+    
+    -- Find all release tags
+    local release_elements = doc:find("a[href*='/releases/tag/']")
+    for _, element in ipairs(release_elements) do
+        local href = element:attr("href")
+        local version = href:match("/releases/tag/(.+)")
+        if version then
+            table.insert(releases, {
+                version = version,
+                url = "https://github.com" .. href
+            })
+        end
+    end
+    
+    return releases
+end
+```
+
+## Archiver Module
+
+The archiver module provides functionality for extracting compressed archives.
+
+### Supported Formats
+
+- **tar.gz** / **tgz** - Gzipped tar archives
+- **tar.xz** - XZ compressed tar archives
+- **zip** - ZIP archives
+- **7z** - 7-Zip archives
+
+### Basic Extraction
+
+```lua
+local archiver = require("vfox.archiver")
+
+-- Extract archive to directory
+local err = archiver.decompress("archive.tar.gz", "extracted/")
+if err ~= nil then
+    error("Extraction failed: " .. err)
+end
+
+-- Extract ZIP file
+local err = archiver.decompress("package.zip", "destination/")
+if err ~= nil then
+    error("ZIP extraction failed: " .. err)
+end
+```
+
+### Real-World Example: Plugin Installation
+
+```lua
+local archiver = require("vfox.archiver")
+local http = require("http")
+
+function install_from_archive(download_url, install_path)
+    -- Download the archive
+    local archive_path = install_path .. "/download.tar.gz"
+    local err = http.download_file({
+        url = download_url
+    }, archive_path)
+    
+    if err ~= nil then
+        error("Download failed: " .. err)
+    end
+    
+    -- Extract to installation directory
+    local err = archiver.decompress(archive_path, install_path)
+    if err ~= nil then
+        error("Extraction failed: " .. err)
+    end
+    
+    -- Clean up archive
+    os.remove(archive_path)
+end
+```
+
+## File Module

+The file module provides file system operations.
+
+### File Operations
+
+```lua
+local file = require("vfox.file")
+
+-- Read file content
+local content = file.read("/path/to/file.txt")
+if content then
+    print("File content: " .. content)
+else
+    error("Failed to read file")
+end
+
+-- Write file content
+local success = file.write("/path/to/output.txt", "Hello, World!")
+if not success then
+    error("Failed to write file")
+end
+
+-- Check if file exists
+if file.exists("/path/to/file.txt") then
+    print("File exists")
+end
+```
+
+### Directory Operations
+
+```lua
+local file = require("vfox.file")
+
+-- Create directory
+local success = file.mkdir("/path/to/new/directory")
+if not success then
+    error("Failed to create directory")
+end
+
+-- Create directory with parents
+local success = file.mkdir_all("/path/to/deep/nested/directory")
+if not success then
+    error("Failed to create directory tree")
+end
+
+-- List directory contents
+local files = file.list_dir("/path/to/directory")
+for _, filename in ipairs(files) do
+    print("Found file: " .. filename)
+end
+```
+
+## Environment Module
+
+The env module provides environment variable operations.
+
+### Environment Variables
+
+```lua
+local env = require("vfox.env")
+
+-- Get environment variable
+local home = env.get("HOME")
+local path = env.get("PATH")
+
+-- Set environment variable
+env.set("MY_VARIABLE", "my_value")
+
+-- Check if environment variable exists
+if env.exists("NODE_ENV") then
+    print("NODE_ENV is set to: " .. env.get("NODE_ENV"))
+end
+```
+
+### Path Operations
+
+```lua
+local env = require("vfox.env")
+
+-- Get current PATH
+local current_path = env.get("PATH")
+
+-- Add to PATH
+local new_path = "/usr/local/bin:" .. current_path
+env.set("PATH", new_path)
+
+-- Platform-specific PATH separator
+local separator = package.config:sub(1,1) == '\\' and ";" or ":"
+local paths = {"/usr/local/bin", "/opt/bin", current_path}
+env.set("PATH", table.concat(paths, separator))
+```
+
+## Command Module
+
+The cmd module provides shell command execution.
+
+### Basic Command Execution
+
+```lua
+local cmd = require("cmd")
+
+-- Execute command and get output
+local output = cmd.exec("ls -la")
+print("Directory listing:", output)
+
+-- Execute command with error handling
+local success, output = pcall(cmd.exec, "some-command")
+if not success then
+    error("Command failed: " .. output)
+end
+```
+
+### Platform-Specific Commands
+
+```lua
+local cmd = require("cmd")
+
+-- Cross-platform command execution
+local function is_windows()
+    return package.config:sub(1,1) == '\\'
+end
+
+local function get_os_info()
+    if is_windows() then
+        return cmd.exec("systeminfo")
+    else
+        return cmd.exec("uname -a")
+    end
+end
+
+local os_info = get_os_info()
+print("OS Info:", os_info)
+```
+
+## Practical Examples
+
+### Version Fetching from API
+
+```lua
+local http = require("http")
+local json = require("json")
+
+function fetch_npm_versions(package_name)
+    local resp, err = http.get({
+        url = "https://registry.npmjs.org/" .. package_name,
+        headers = {
+            ['User-Agent'] = "mise-plugin"
+        }
+    })
+    
+    if err ~= nil then
+        error("Failed to fetch package info: " .. err)
+    end
+    
+    local package_info = json.decode(resp.body)
+    local versions = {}
+    
+    for version, _ in pairs(package_info.versions) do
+        table.insert(versions, version)
+    end
+    
+    -- Sort versions (simple string sort)
+    table.sort(versions)
+    
+    return versions
+end
+```
+
+### File Download with Progress
+
+```lua
+local http = require("http")
+local file = require("vfox.file")
+
+function download_with_verification(url, dest_path, expected_sha256)
+    -- Download file
+    local err = http.download_file({
+        url = url,
+        headers = {
+            ['User-Agent'] = "mise-plugin"
+        }
+    }, dest_path)
+    
+    if err ~= nil then
+        error("Download failed: " .. err)
+    end
+    
+    -- Verify file exists
+    if not file.exists(dest_path) then
+        error("Downloaded file not found")
+    end
+    
+    -- Note: SHA256 verification would need additional implementation
+    -- This is a simplified example
+    print("Downloaded successfully to: " .. dest_path)
+end
+```
+
+### Configuration File Parsing
+
+```lua
+local file = require("vfox.file")
+local json = require("json")
+local strings = require("vfox.strings")
+
+function parse_config_file(config_path)
+    if not file.exists(config_path) then
+        return {}  -- Return empty config
+    end
+    
+    local content = file.read(config_path)
+    if not content then
+        error("Failed to read config file: " .. config_path)
+    end
+    
+    -- Trim whitespace
+    content = strings.trim_space(content)
+    
+    -- Parse JSON
+    local success, config = pcall(json.decode, content)
+    if not success then
+        error("Invalid JSON in config file: " .. config_path)
+    end
+    
+    return config
+end
+```
+
+### Web Scraping for Versions
+
+```lua
+local http = require("http")
+local html = require("html")
+local strings = require("vfox.strings")
+
+function scrape_versions_from_releases(base_url)
+    local resp, err = http.get({
+        url = base_url .. "/releases"
+    })
+    
+    if err ~= nil then
+        error("Failed to fetch releases page: " .. err)
+    end
+    
+    local doc = html.parse(resp.body)
+    local versions = {}
+    
+    -- Find version tags
+    local version_elements = doc:find("h2 a[href*='/releases/tag/']")
+    for _, element in ipairs(version_elements) do
+        local version_text = element:text()
+        local version = strings.trim_space(version_text)
+        
+        -- Remove 'v' prefix if present
+        version = strings.trim_prefix(version, "v")
+        
+        if version and version ~= "" then
+            table.insert(versions, {
+                version = version,
+                url = base_url .. element:attr("href")
+            })
+        end
+    end
+    
+    return versions
+end
+```
+
+## Best Practices
+
+### Error Handling
+
+Always handle errors gracefully:
+
+```lua
+local http = require("http")
+local json = require("json")
+
+function safe_api_call(url)
+    local resp, err = http.get({url = url})
+    
+    if err ~= nil then
+        error("HTTP request failed: " .. err)
+    end
+    
+    if resp.status_code ~= 200 then
+        error("API returned error: " .. resp.status_code .. " " .. resp.body)
+    end
+    
+    local success, data = pcall(json.decode, resp.body)
+    if not success then
+        error("Failed to parse JSON response: " .. data)
+    end
+    
+    return data
+end
+```
+
+### Caching
+
+Implement caching for expensive operations:
+
+```lua
+local cache = {}
+local cache_ttl = 3600  -- 1 hour
+
+function cached_http_get(url)
+    local now = os.time()
+    local cache_key = url
+    
+    -- Check cache
+    if cache[cache_key] and (now - cache[cache_key].timestamp) < cache_ttl then
+        return cache[cache_key].data
+    end
+    
+    -- Fetch fresh data
+    local http = require("http")
+    local resp, err = http.get({url = url})
+    
+    if err ~= nil then
+        error("HTTP request failed: " .. err)
+    end
+    
+    -- Cache the result
+    cache[cache_key] = {
+        data = resp,
+        timestamp = now
+    }
+    
+    return resp
+end
+```
+
+### Platform Detection
+
+Handle cross-platform differences:
+
+```lua
+local function get_platform_info()
+    local is_windows = package.config:sub(1,1) == '\\'
+    local cmd = require("cmd")
+    
+    if is_windows then
+        return {
+            os = "windows",
+            arch = os.getenv("PROCESSOR_ARCHITECTURE") or "x64",
+            path_sep = "\\",
+            env_sep = ";"
+        }
+    else
+        local uname = cmd.exec("uname -s"):lower()
+        local arch = cmd.exec("uname -m")
+        
+        return {
+            os = uname,
+            arch = arch,
+            path_sep = "/",
+            env_sep = ":"
+        }
+    end
+end
+```

+# Plugin Publishing
+
+This guide shows how to publish and distribute your plugins, whether they are backend plugins or tool plugins. Publishing makes your plugins available to other users and ensures they can be easily installed and maintained.
+
+## Publishing Checklist
+
+Before publishing your plugin, ensure you have:
+
+### Essential Files
+
+- **`metadata.lua`** - Plugin metadata with name, version, description, and author
+- **Plugin implementation** - Either backend methods or hook functions
+- **Test coverage** - Automated tests to verify functionality
+
+### Optional but Recommended
+
+- **`README.md`** - Basic usage instructions and examples
+- **`test/`** directory - Test scripts for verification
+- **Version control** - Git repository with proper versioning
+
+## Repository Setup
+
+### 1. Initialize Repository
+
+Create a Git repository for your plugin:
+
+```bash
+# Create plugin directory
+mkdir my-plugin
+cd my-plugin
+
+# Initialize git repository
+git init
+git remote add origin https://github.com/username/my-plugin.git
+
+# Create initial structure
+touch metadata.lua
+mkdir -p test
+echo "# My Plugin" > README.md
+```
+
+### 2. Basic Directory Structure
+
+Organize your plugin with this structure:
+
+```
+my-plugin/
+├── metadata.lua          # Plugin metadata
+├── README.md            # Basic documentation
+├── test/                # Test scripts
+│   └── test.sh
+├── .gitignore           # Git ignore rules
+└── [implementation files]
+```
+
+For backend plugins:
+
+```
+backend-plugin/
+├── metadata.lua          # Backend methods implementation
+├── README.md
+└── test/
+    └── test.sh
+```
+
+For tool plugins:
+
+```
+tool-plugin/
+├── metadata.lua          # Plugin metadata
+├── hooks/               # Hook implementations
+│   ├── available.lua
+│   ├── pre_install.lua
+│   └── env_keys.lua
+├── lib/                 # Helper libraries
+│   └── helper.lua
+├── README.md
+└── test/
+    └── test.sh
+```
+
+### 3. Git Ignore Configuration
+
+Create a `.gitignore` file:
+
+```gitignore
+# Temporary files
+*.tmp
+*.temp
+.DS_Store
+Thumbs.db
+
+# Test artifacts
+test/tmp/
+test/output/
+
+# IDE files
+.vscode/
+.idea/
+*.swp
+*.swo
+
+# OS files
+*.log
+```
+
+## Versioning Strategy
+
+### Semantic Versioning
+
+Use semantic versioning (SemVer) for your plugin releases:
+
+- **Major version** (1.0.0 → 2.0.0): Breaking changes
+- **Minor version** (1.0.0 → 1.1.0): New features, backward compatible
+- **Patch version** (1.0.0 → 1.0.1): Bug fixes, backward compatible
+
+### Version Management
+
+Update version in `metadata.lua`:
+
+```lua
+PLUGIN = {
+    name = "my-plugin",
+    version = "1.2.3",  -- Update this for each release
+    description = "My awesome plugin",
+    author = "Your Name"
+}
+```
+
+Create git tags for releases:
+
+```bash
+# Tag the current commit
+git tag -a v1.2.3 -m "Release version 1.2.3"
+
+# Push tags to repository
+git push origin --tags
+```
+
+## Testing Before Publication
+
+### Automated Testing
+
+Create comprehensive test scripts:
+
+```bash
+#!/bin/bash
+# test/test.sh
+set -e
+
+echo "Testing plugin functionality..."
+
+# Install plugin locally
+mise plugin install my-plugin .
+
+# Test basic functionality
+if [[ "$(mise ls-remote my-plugin)" == "" ]]; then
+    echo "ERROR: No versions available"
+    exit 1
+fi
+
+# Test installation
+mise install my-plugin@latest
+
+# Test execution
+mise exec my-plugin:tool -- --version
+
+# Clean up
+mise plugin remove my-plugin
+
+echo "All tests passed!"
+```
+
+### Manual Testing
+
+Test your plugin manually:
+
+```bash
+# Link for development
+mise plugin link my-plugin /path/to/plugin
+
+# Test all functionality
+mise ls-remote my-plugin
+mise install my-plugin@latest
+mise use my-plugin@latest
+
+# Test in different environments
+docker run --rm -it ubuntu:latest bash -c "
+    curl -fsSL https://mise.jdx.dev/install.sh | sh
+    mise plugin install my-plugin https://github.com/username/my-plugin
+    mise install my-plugin@latest
+"
+```
+
+## Publishing Process
+
+### 1. Prepare for Release
+
+Before publishing, ensure everything is ready:
+
+```bash
+# Run tests
+./test/test.sh
+
+# Check git status
+git status
+
+# Update version in metadata.lua
+vim metadata.lua
+
+# Commit changes
+git add .
+git commit -m "Prepare release v1.2.3"
+```
+
+### 2. Create Release
+
+Create a tagged release:
+
+```bash
+# Create and push tag
+git tag -a v1.2.3 -m "Release version 1.2.3"
+git push origin v1.2.3
+git push origin main
+```
+
+### 3. GitHub Releases (Recommended)
+
+Create a GitHub release for better discoverability:
+
+1. Go to your repository on GitHub
+2. Click "Releases" → "Create a new release"
+3. Choose your tag (v1.2.3)
+4. Write release notes describing changes
+5. Publish the release
+
+### 4. Release Notes Template
+
+```markdown
+## Changes in v1.2.3
+
+### Added
+- New feature X
+- Support for Y
+
+### Changed

+- Updated dependencies
+
+### Fixed
+- Fixed issue with A
+- Resolved bug in B
+
+### Installation
+```bash
+mise plugin install my-plugin https://github.com/username/my-plugin
+```
+
+```
+
+## Distribution Methods
+
+### 1. Direct Git Installation
+
+Users can install directly from your repository:
+
+```bash
+# Install from GitHub
+mise plugin install my-plugin https://github.com/username/my-plugin
+
+# Install specific version
+mise plugin install my-plugin https://github.com/username/my-plugin@v1.2.3
+
+# Install from other Git providers
+mise plugin install my-plugin https://gitlab.com/username/my-plugin
+```
+
+### 2. Private Repository Access
+
+For private repositories, users need access:
+
+```bash
+# SSH access (recommended)
+mise plugin install my-plugin git@github.com:username/private-plugin.git
+
+# HTTPS with token
+mise plugin install my-plugin https://username:token@github.com/username/private-plugin.git
+```
+
+### 3. Archive Distribution
+
+You can also distribute as archives:
+
+```bash
+# Create release archive
+git archive --format=zip --output=my-plugin-v1.2.3.zip v1.2.3
+
+# Users can install from archive
+mise plugin install my-plugin https://github.com/username/my-plugin/releases/download/v1.2.3/my-plugin-v1.2.3.zip
+```
+
+## Maintenance and Updates
+
+### 1. Update Workflow
+
+Establish a regular update process:
+
+```bash
+# Development workflow
+git checkout -b feature/new-feature
+# ... make changes ...
+git commit -m "Add new feature"
+git push origin feature/new-feature
+
+# After review and merge
+git checkout main
+git pull origin main
+git tag -a v1.3.0 -m "Release v1.3.0"
+git push origin v1.3.0
+```
+
+### 2. Backward Compatibility
+
+Maintain backward compatibility when possible:
+
+- Keep existing plugin interface unchanged

+### Tool Plugins
+
+Tool plugins use the traditional hook-based approach:
+
+- **Single Tool**: Each plugin manages one tool
+- **Hook-based**: Use hooks like `PreInstall`, `PostInstall`, `Available`, etc.
+- **Format**: Use the tool name directly (e.g., `my-tool`)

+## Backend Plugins
 
-mise provides a modern cross-platform plugin system that extends the vfox plugin architecture. These plugins have several advantages over asdf (legacy) plugins:
+Backend plugins provide enhanced functionality with modern backend methods. These plugins use the `plugin:tool` format and offer advantages over traditional plugins:
 
+- **Multiple Tools**: A single plugin can manage multiple tools
+- **Enhanced Methods**: Backend methods for listing versions, installing, and setting environment variables
 - **Cross-platform**: Work on Windows, macOS, and Linux
 - **Performance**: Faster execution than shell-based plugins
-- **Modern Features**: Support for the `plugin:tool` format and enhanced backend methods
 
-You can create and use plugins that aren't available in the standard registry. This enables:
-
-- Installing tools from private repositories
-- Using experimental or niche tools
-- Creating custom tool installations for your team
-
-Plugins use the `plugin:tool` format, allowing a single plugin to manage multiple tools. For example:

+- **Single Tool**: Each plugin manages one tool
+- **Cross-platform**: Work on Windows, macOS, and Linux
+- **Flexible**: Full control over installation and environment setup

+# Tool Plugin Development
+
+Tool plugins use a hook-based architecture to manage individual tools. They are compatible with the standard vfox ecosystem and are perfect for tools that need complex installation logic, environment configuration, or legacy file parsing.
+
+## What are Tool Plugins?
+
+Tool plugins use traditional hook functions to manage a single tool. They provide:
+
+- **Standard vfox Compatibility**: Works with both mise and vfox
+- **Complex Installation Logic**: Handle source compilation, custom builds, and complex setups
+- **Environment Configuration**: Set up complex environment variables beyond just PATH
+- **Legacy File Support**: Parse version files from other tools (`.nvmrc`, `.tool-version`, etc.)
+- **Cross-Platform Support**: Works on Windows, macOS, and Linux
+
+## Plugin Architecture
+
+Tool plugins use a hook-based architecture with specific functions for different lifecycle events:

+
+## Hook Functions
+
+### Required Hooks
+
+These hooks must be implemented for a functional plugin:
+
+#### Available Hook
+
+Lists all available versions of the tool:
+
+```lua
+-- hooks/available.lua
+function PLUGIN:Available(ctx)
+    local args = ctx.args  -- User arguments
+    
+    -- Return array of available versions
+    return {
+        {
+            version = "20.0.0",
+            note = "Latest"
+        },
+        {
+            version = "18.18.0",
+            note = "LTS",
+            addition = {
+                {
+                    name = "npm",
+                    version = "9.8.1"
+                }
+            }
+        }
+    }
+end
+```
+
+#### PreInstall Hook
+
+Handles pre-installation logic and returns download information:
+
+```lua
+-- hooks/pre_install.lua
+function PLUGIN:PreInstall(ctx)
+    local version = ctx.version
+    local runtimeVersion = ctx.runtimeVersion
+    
+    -- Determine download URL and checksums
+    local url = "https://nodejs.org/dist/v" .. version .. "/node-v" .. version .. "-linux-x64.tar.gz"
+    
+    return {
+        version = version,
+        url = url,
+        sha256 = "abc123...",  -- Optional checksum
+        note = "Installing Node.js " .. version,
+        -- Additional files can be specified
+        addition = {
+            {
+                name = "npm",
+                url = "https://registry.npmjs.org/npm/-/npm-" .. npm_version .. ".tgz"
+            }
+        }
+    }
+end
+```
+
+#### EnvKeys Hook
+
+Configures environment variables for the installed tool:
+
+```lua
+-- hooks/env_keys.lua
+function PLUGIN:EnvKeys(ctx)
+    local mainPath = ctx.path
+    local runtimeVersion = ctx.runtimeVersion
+    local sdkInfo = ctx.sdkInfo['nodejs']
+    local path = sdkInfo.path
+    local version = sdkInfo.version
+    local name = sdkInfo.name
+    
+    return {
+        {
+            key = "NODE_HOME",
+            value = mainPath
+        },
+        {
+            key = "PATH",
+            value = mainPath .. "/bin"
+        },
+        -- Multiple PATH entries are automatically merged
+        {
+            key = "PATH", 
+            value = mainPath .. "/lib/node_modules/.bin"
+        }
+    }
+end
+```
+
+### Optional Hooks
+
+These hooks provide additional functionality:
+
+#### PostInstall Hook
+
+Performs additional setup after installation:
+
+```lua
+-- hooks/post_install.lua
+function PLUGIN:PostInstall(ctx)
+    local rootPath = ctx.rootPath
+    local runtimeVersion = ctx.runtimeVersion
+    local sdkInfo = ctx.sdkInfo['nodejs']
+    local path = sdkInfo.path
+    local version = sdkInfo.version
+    
+    -- Compile native modules, set permissions, etc.
+    local result = os.execute("chmod +x " .. path .. "/bin/*")
+    if result ~= 0 then
+        error("Failed to set permissions")
+    end
+    
+    -- No return value needed
+end
+```
+
+#### PreUse Hook
+
+Modifies version before use:
+
+```lua
+-- hooks/pre_use.lua
+function PLUGIN:PreUse(ctx)
+    local version = ctx.version
+    local previousVersion = ctx.previousVersion
+    local installedSdks = ctx.installedSdks
+    local cwd = ctx.cwd
+    local scope = ctx.scope  -- global/project/session
+    
+    -- Optionally modify the version
+    if version == "latest" then
+        version = "20.0.0"  -- Resolve to specific version
+    end
+    
+    return {
+        version = version
+    }
+end
+```
+
+#### ParseLegacyFile Hook
+
+Parses version files from other tools:
+
+```lua
+-- hooks/parse_legacy_file.lua
+function PLUGIN:ParseLegacyFile(ctx)
+    local filename = ctx.filename
+    local filepath = ctx.filepath
+    local versions = ctx:getInstalledVersions()
+    
+    -- Read and parse the file
+    local file = require("vfox.file")
+    local content = file.read(filepath)
+    local version = content:match("v?([%d%.]+)")
+    
+    return {
+        version = version
+    }
+end
+```
+
+## Creating a Tool Plugin
+
+### 1. Plugin Structure
+
+Create a directory with this structure:
+
+```
+nodejs-plugin/
+├── metadata.lua          # Plugin metadata and configuration
+├── hooks/               # Hook functions directory
+│   ├── available.lua    # List available versions [required]
+│   ├── pre_install.lua  # Pre-installation hook [required]
+│   ├── env_keys.lua     # Environment configuration [required]
+│   ├── post_install.lua # Post-installation hook [optional]
+│   ├── pre_use.lua      # Pre-use hook [optional]
+│   └── parse_legacy_file.lua # Legacy file parser [optional]
+├── lib/                 # Shared library code [optional]
+│   └── helper.lua       # Helper functions
+└── test/               # Test scripts [optional]
+    └── test.sh
+```
+
+### 2. metadata.lua
+
+Configure plugin metadata and legacy file support:
+
+```lua
+-- metadata.lua
+PLUGIN = {
+    name = "nodejs",
+    version = "1.0.0",
+    description = "Node.js runtime environment",
+    author = "Plugin Author",
+    
+    -- Legacy version files this plugin can parse
+    legacyFilenames = {
+        '.nvmrc',
+        '.node-version'
+    }
+}
+```
+
+### 3. Helper Libraries
+
+Create shared functions in the `lib/` directory:
+
+```lua
+-- lib/helper.lua
+local M = {}
+
+function M.get_arch()
+    local arch = os.getenv("PROCESSOR_ARCHITECTURE") or os.capture("uname -m")
+    if arch:match("x86_64") or arch:match("AMD64") then
+        return "x64"
+    elseif arch:match("i386") or arch:match("i686") then
+        return "x86"
+    elseif arch:match("arm64") or arch:match("aarch64") then
+        return "arm64"
+    else
+        return "x64"  -- default
+    end
+end
+
+function M.get_os()
+    if package.config:sub(1,1) == '\\' then
+        return "win"
+    else
+        local os_name = os.capture("uname"):lower()
+        if os_name:find("darwin") then
+            return "darwin"
+        else
+            return "linux"
+        end
+    end
+end
+
+function M.get_platform()
+    return M.get_os() .. "-" .. M.get_arch()
+end
+
+return M
+```
+
+## Real-World Example: vfox-nodejs
+
+Here's a complete example based on the vfox-nodejs plugin that demonstrates all the concepts:
+
+### Available Hook Example
+
+```lua
+-- hooks/available.lua
+function PLUGIN:Available(ctx)
+    local http = require("http")
+    local json = require("json")
+    
+    -- Fetch versions from Node.js API
+    local resp, err = http.get({
+        url = "https://nodejs.org/dist/index.json"
+    })
+    
+    if err ~= nil then
+        error("Failed to fetch versions: " .. err)
+    end
+    
+    local versions = json.decode(resp.body)
+    local result = {}
+    
+    for i, v in ipairs(versions) do
+        local version = v.version:gsub("^v", "")  -- Remove 'v' prefix
+        local note = nil
+        
+        if v.lts then
+            note = "LTS"
+        end
+        
+        table.insert(result, {
+            version = version,
+            note = note,
+            addition = {
+                {
+                    name = "npm",
+                    version = v.npm
+                }
+            }
+        })
+    end
+    
+    return result
+end
+```
+
+### PreInstall Hook Example
+
+```lua
+-- hooks/pre_install.lua
+function PLUGIN:PreInstall(ctx)
+    local version = ctx.version
+    local helper = require("lib/helper")
+    
+    -- Determine platform
+    local platform = helper.get_platform()
+    local extension = platform:match("win") and "zip" or "tar.gz"
+    
+    -- Build download URL
+    local filename = "node-v" .. version .. "-" .. platform .. "." .. extension
+    local url = "https://nodejs.org/dist/v" .. version .. "/" .. filename
+    
+    -- Fetch checksum
+    local http = require("http")
+    local shasums_url = "https://nodejs.org/dist/v" .. version .. "/SHASUMS256.txt"
+    local resp, err = http.get({ url = shasums_url })
+    
+    local sha256 = nil
+    if err == nil then
+        -- Extract SHA256 for our file
+        for line in resp.body:gmatch("[^\n]+") do
+            if line:match(filename) then
+                sha256 = line:match("^(%w+)")
+                break
+            end
+        end
+    end
+    
+    return {
+        version = version,
+        url = url,
+        sha256 = sha256,
+        note = "Installing Node.js " .. version .. " (" .. platform .. ")"
+    }
+end
+```
+
+### EnvKeys Hook Example
+
+```lua
+-- hooks/env_keys.lua
+function PLUGIN:EnvKeys(ctx)
+    local mainPath = ctx.path
+    local helper = require("lib/helper")
+    local os_type = helper.get_os()
+    
+    local env_vars = {
+        {
+            key = "NODE_HOME",
+            value = mainPath
+        },
+        {
+            key = "PATH",
+            value = mainPath .. "/bin"
+        }
+    }
+    
+    -- Add npm global modules to PATH
+    local npm_global_path = mainPath .. "/lib/node_modules/.bin"
+    if os_type == "win" then
+        npm_global_path = mainPath .. "/node_modules/.bin"
+    end
+    
+    table.insert(env_vars, {
+        key = "PATH",
+        value = npm_global_path
+    })
+    
+    return env_vars
+end
+```
+
+### PostInstall Hook Example
+
+```lua
+-- hooks/post_install.lua
+function PLUGIN:PostInstall(ctx)
+    local sdkInfo = ctx.sdkInfo['nodejs']
+    local path = sdkInfo.path
+    local helper = require("lib/helper")
+    
+    -- Set executable permissions on Unix systems
+    if helper.get_os() ~= "win" then
+        os.execute("chmod +x " .. path .. "/bin/*")
+    end
+    
+    -- Create npm cache directory
+    local npm_cache_dir = path .. "/.npm"
+    os.execute("mkdir -p " .. npm_cache_dir)
+    
+    -- Configure npm to use local cache
+    local npm_cmd = path .. "/bin/npm"
+    if helper.get_os() == "win" then
+        npm_cmd = path .. "/npm.cmd"
+    end
+    
+    os.execute(npm_cmd .. " config set cache " .. npm_cache_dir)
+    os.execute(npm_cmd .. " config set prefix " .. path)
+end
+```
+
+### Legacy File Support
+
+```lua
+-- hooks/parse_legacy_file.lua
+function PLUGIN:ParseLegacyFile(ctx)
+    local filename = ctx.filename
+    local filepath = ctx.filepath
+    local file = require("vfox.file")
+    
+    -- Read file content
+    local content = file.read(filepath)
+    if not content then
+        error("Failed to read " .. filepath)
+    end
+    
+    -- Parse version from different file formats
+    local version = nil
+    
+    if filename == ".nvmrc" then
+        -- .nvmrc can contain version with or without 'v' prefix
+        version = content:match("v?([%d%.]+)")
+    elseif filename == ".node-version" then
+        -- .node-version typically contains just the version number
+        version = content:match("([%d%.]+)")
+    end
+    
+    -- Remove any whitespace
+    if version then
+        version = version:gsub("%s+", "")
+    end
+    
+    return {
+        version = version
+    }
+end
+```
+
+## Testing Your Plugin
+
+### Local Development
+
+```bash
+# Link your plugin for development
+mise plugin link nodejs /path/to/nodejs-plugin
+
+# Test listing versions
+mise ls-remote nodejs
+
+# Test installation
+mise install nodejs@20.0.0
+
+# Test environment setup
+mise use nodejs@20.0.0
+node --version
+
+# Test legacy file parsing
+echo "18.18.0" > .nvmrc
+mise use nodejs
+```
+
+### Debug Mode
+
+Use debug mode to see detailed plugin execution:
+
+```bash
+mise --debug install nodejs@20.0.0
+```
+
+### Plugin Test Script
+
+Create a comprehensive test script:
+
+```bash
+#!/bin/bash
+# test/test.sh
+set -e
+
+echo "Testing nodejs plugin..."
+
+# Install the plugin
+mise plugin install nodejs .
+
+# Test basic functionality
+mise install nodejs@18.18.0
+mise use nodejs@18.18.0
+
+# Verify installation
+node --version | grep "18.18.0"
+npm --version
+
+# Test legacy file support
+echo "20.0.0" > .nvmrc
+mise use nodejs
+node --version | grep "20.0.0"
+
+# Clean up
+rm -f .nvmrc
+mise plugin remove nodejs
+
+echo "All tests passed!"
+```
+
+## Best Practices
+
+### Error Handling
+
+Always provide meaningful error messages:
+
+```lua
+function PLUGIN:Available(ctx)
+    local http = require("http")
+    local resp, err = http.get({
+        url = "https://api.example.com/versions"
+    })
+    
+    if err ~= nil then
+        error("Failed to fetch versions from API: " .. err)
+    end
+    
+    if resp.status_code ~= 200 then
+        error("API returned status " .. resp.status_code .. ": " .. resp.body)
+    end
+    
+    -- Process response...
+end
+```
+
+### Platform Detection
+
+Handle different operating systems properly:
+
+```lua
+-- lib/platform.lua
+local M = {}
+
+function M.is_windows()
+    return package.config:sub(1,1) == '\\'
+end
+
+function M.get_exe_extension()
+    return M.is_windows() and ".exe" or ""
+end
+
+function M.get_path_separator()
+    return M.is_windows() and "\\" or "/"
+end
+
+return M
+```
+
+### Version Normalization
+
+Normalize versions consistently:
+
+```lua
+local function normalize_version(version)
+    -- Remove 'v' prefix if present
+    version = version:gsub("^v", "")
+    
+    -- Remove pre-release suffixes
+    version = version:gsub("%-.*", "")
+    
+    return version
+end
+```
+
+### Caching
+
+Cache expensive operations:
+
+```lua
+-- Cache versions for 12 hours
+local cache = {}
+local cache_ttl = 12 * 60 * 60  -- 12 hours in seconds
+
+function PLUGIN:Available(ctx)
+    local now = os.time()
+    
+    -- Check cache first
+    if cache.versions and cache.timestamp and (now - cache.timestamp) < cache_ttl then
+        return cache.versions
+    end
+    
+    -- Fetch fresh data
+    local versions = fetch_versions_from_api()
+    
+    -- Update cache
+    cache.versions = versions
+    cache.timestamp = now
+    
+    return versions
+end
+```
+
+## Advanced Features
+
+### Conditional Installation
+
+Different installation logic based on platform or version:
+
+```lua
+function PLUGIN:PreInstall(ctx)
+    local version = ctx.version
+    local helper = require("lib/helper")
+    local platform = helper.get_platform()
+    
+    -- Different logic for different platforms
+    if platform:match("win") then
+        -- Windows-specific installation
+        return install_windows(version)
+    elseif platform:match("darwin") then
+        -- macOS-specific installation
+        return install_macos(version)
+    else
+        -- Linux installation
+        return install_linux(version)
+    end
+end
+```
+
+### Source Compilation
+
+For plugins that need to compile from source:
+
+```lua
+-- hooks/post_install.lua
+function PLUGIN:PostInstall(ctx)
+    local sdkInfo = ctx.sdkInfo['tool-name']
+    local path = sdkInfo.path
+    local version = sdkInfo.version
+    
+    -- Change to source directory
+    local build_dir = path .. "/src"
+    
+    -- Configure build
+    local configure_result = os.execute("cd " .. build_dir .. " && ./configure --prefix=" .. path)
+    if configure_result ~= 0 then
+        error("Configure failed")
+    end
+    
+    -- Compile
+    local make_result = os.execute("cd " .. build_dir .. " && make -j$(nproc)")
+    if make_result ~= 0 then
+        error("Compilation failed")
+    end
+    
+    -- Install
+    local install_result = os.execute("cd " .. build_dir .. " && make install")
+    if install_result ~= 0 then
+        error("Installation failed")
+    end
+end
+```
+
+### Environment Configuration
+
+Complex environment variable setup:
+
+```lua
+function PLUGIN:EnvKeys(ctx)
+    local mainPath = ctx.path
+    local version = ctx.sdkInfo['tool-name'].version
+    
+    local env_vars = {
+        -- Standard environment variables
+        {
+            key = "TOOL_HOME",
+            value = mainPath
+        },
+        {
+            key = "TOOL_VERSION",
+            value = version
+        },
+        
+        -- PATH entries
+        {
+            key = "PATH",
+            value = mainPath .. "/bin"
+        },
+        {
+            key = "PATH",
+            value = mainPath .. "/scripts"
+        },
+        
+        -- Library paths
+        {
+            key = "LD_LIBRARY_PATH",
+            value = mainPath .. "/lib"
+        },
+        {
+            key = "PKG_CONFIG_PATH",
+            value = mainPath .. "/lib/pkgconfig"
+        }
+    }
+    
+    -- Platform-specific additions
+    local helper = require("lib/helper")
+    if helper.get_os() == "darwin" then
+        table.insert(env_vars, {
+            key = "DYLD_LIBRARY_PATH",
+            value = mainPath .. "/lib"
+        })
+    end
+    
+    return env_vars
+end
+```

+It relies on asdf plugins for each tool. asdf plugins are more risky to use because they're typically written by a single developer unrelated to the tool vendor. They also generally do not function on Windows because they're written
+in bash which is often not available on Windows and the scripts generally are not written to be cross-platform.
 
 asdf plugins are not used for tools inside the [registry](https://github.com/jdx/mise/blob/main/registry.toml) whenever possible. Sometimes it is not possible to use more secure backends like aqua/ubi because tools have complex install setups or need to export env vars.

 ## Usage Example
 
-With the vfox-npm plugin installed, you can manage npm packages:
+The plugin name doesn't have to match the repository name. The backend prefix will match whatever name the backend plugin was installed as.

 # Install the plugin

+> **Tip**: This naming flexibility could potentially be used to have a very complex plugin backend that would behave differently based on what it was named. For example, you could install the same plugin with different names to configure different behaviors or access different tool registries.

 ## Context Variables
 
 Backend plugins receive context through the `ctx` parameter passed to each hook function:
 
+### BackendListVersions Context
+
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `ctx.tool` | The tool name | `"prettier"` |

+### BackendInstall and BackendExecEnv Context

 | Variable | Description | Example |
 |----------|-------------|---------|
 | `ctx.tool` | The tool name | `"prettier"` |
 | `ctx.version` | The requested version | `"3.0.0"` |
 | `ctx.install_path` | Installation directory | `"/home/user/.local/share/mise/installs/vfox-npm/prettier/3.0.0"` |
