- Line 101: Update the state-isolation guidance in the getting-started
documentation to remove the claim that --state is a general state-root option
for server start, workspace mutations, or server stop. Explain that --session
selects a session rather than a separate state root, document the supported
state mechanism, and require consistent --session, --socket, or socket
environment settings across commands.

| Put the product name and an instance discriminator in the session name, for example `firstmate-a1b2c3`. Two installations of one product then coexist on one machine without cross-matching each other's workspaces. Address every call with `--session <name>` or the exact `--socket` path, and store the typed resource IDs a mutation returns instead of resolving by display name later. | ||

| The default config path is shared with the person's own cmux-tui and can enable a machine provider or key remaps the product does not expect. Point `CMUX_TUI_CONFIG` at a product-owned config file. Sessions already keep separate state subtrees under the platform state directory; pass `--state <path>` only when the product must keep its state out of the shared root entirely. |

💡 Result:
CMUX_TUI_CONFIG is an environment variable used by cmux-tui to locate its configuration file [1][2]. When cmux-tui starts, it resolves its configuration path using the following order of precedence: 1. The path specified by the CMUX_TUI_CONFIG environment variable [1][3]. 2. The legacy CMUX_MUX_CONFIG environment variable [1][2]. 3. The default configuration file location at $XDG_CONFIG_HOME/cmux/cmux-tui.json or /.config/cmux/cmux-tui.json [1]. 4. A legacy mux.json file (if cmux-tui.json is absent) [1][3]. The expression CMUX_TUI_CONFIG --state cmux-tui does not appear to be a standard or valid command-line invocation for the cmux-tui binary. Based on technical documentation, CMUX_TUI_CONFIG is exclusively an environment variable [1][2], and --state is not listed as a supported top-level flag for the cmux-tui CLI [4]. If you are attempting to configure the tool, you should set the environment variable to point to your configuration file (e.g., export CMUX_TUI_CONFIG=/.config/cmux/cmux-tui.json) [1]. If you are looking for information regarding TUI state, the cmux-tui control protocol uses specific commands and events to handle state, such as reload-config [3] or initial --state events in the communication stream [5].

💡 Result:
cmux-tui is a terminal multiplexer that manages durable sessions, workspaces, and terminal resources [1][2]. Its server-based architecture allows for detached sessions and persistent workspaces [1][3]. Server Lifecycle Management The cmux-tui server manages a durable session, which includes the backend process and control socket [1][4]. You can control this lifecycle using the following canonical commands: server start: Initializes the local durable server for a named session [5][1]. server stop: Performs a graceful shutdown of the local server, its owner, and all associated workspaces [5][6]. This operation is idempotent (succeeding even if the server is already absent) and preserves the durable workspace topology [5][6]. server status: Checks the status of a specific named session [5][1]. server reload-config: Reloads the server configuration [5][6]. Commands can be targeted to specific sessions using the --session flag, which can also precede the command scope (e.g., cmux --session agents server status) [5][1][6]. Workspace and Session State State persistence is handled as follows: Session State: A session is defined by one mux backend and its control socket [4]. Default sockets are stored in $TMPDIR/cmux-tui-/.sock, though this can be overridden with --socket [1][7]. Workspace State: Workspace identity, mutation results, and frontend projections are stored in a SQLite database [7]. The default location for this state is in the platform-specific application support directory (e.g., ~/Library/Application Support/cmux-tui/sessions on macOS), or as specified by the --state flag [7]. Durability: Because state is persisted in this SQLite database, restarting the server or stopping it via server stop does not destroy the workspace topology; it is preserved for future sessions [6][7]. You can manage workspaces using the noun-first CLI, such as cmux workspace create --name [1]. If you need to stop a session's execution, session current stop is an alias for the same operation as server stop [5][6].

github manaflow-ai/cmux cmux-tui source config state
💡 Result:
cmux (by manaflow-ai) is a Ghostty-based macOS terminal designed for AI coding agents [1][2]. The repository contains both a native macOS app (cmux) and a Rust-based terminal multiplexer (cmux-tui) [3][4]. Configuration and State Overview: Config Files: - macOS App: cmux reads its configuration primarily from cmux.json (JSONC format) [5] and also reads existing ~/.config/ghostty/config files for terminal themes and settings [1]. It includes a unified settings utility window for managing these sources [6]. - cmux-tui: The TUI resolves configuration in the following order: CMUX_TUI_CONFIG (environment variable), ~/.config/cmux/cmux-tui.json, or $XDG_CONFIG_HOME/cmux/cmux-tui.json [7][8]. Legacy mux.json files are also supported if the newer configuration file is absent [7][8]. - Dock: Dock-specific configuration is looked for at .cmux/dock.json (project-level) or ~/.config/cmux/dock.json (global) [9]. State and Persistence: - Session Restore: cmux restores layouts and metadata across relaunches [2]. It does not checkpoint arbitrary live process states (e.g., shells like vim or tmux), but supports session resumption for compatible agent hooks [2]. - Managed Defaults: The application uses a KeyboardShortcutSettingsFileStore to manage and replay defaults, ensuring user-defined settings persist correctly without being overwritten by managed configurations [10]. - CLI Utilities: The cmux config CLI command provides tools for validating configuration files (doctor), reloading settings, and viewing paths [5]. For developers, the cmux-tui directory contains the Rust source code for the multiplexer, which manages machines, sessions, workspaces, and panes [3]. It utilizes a socket-based protocol (cmux.protocol/2) for communication [3].

🌐 Web query:
site:github.com/manaflow-ai/cmux/blob/main/cmux-tui/spec/cli.md "state" "session" "server start"
💡 Result:
The command "cmux server start" is used within the cmux (a multiplexer tool) environment to initiate a local durable mux owner for a specific session [1]. In this context, server start acts as the canonical foreground operation for starting the session server [1]. When executed, this command defers detached startup until the cmux process establishes explicit supervisor ownership, verifies readiness, manages PID and state tracking, and sets up crash and stop contracts [1]. Key behaviors of the server start command include: - It serves as an alternative to the --headless flag [1]. - It creates a local socket that accepts protocol clients even while the owner is finishing its startup sequence [1]. - It initiates a process that can only be stopped via the server stop command, which subsequently shuts down the local owner and its associated workspaces [1]. If you are using a different software or framework, the command might differ; however, "state session server start" is not a standard command in common infrastructure or web server software. If you were looking for a different tool, please verify the specific application or platform you are using.

💡 Result:
The CMUX_TUI_CONFIG environment variable is used to specify the path to your configuration file for cmux-tui [1]. It is one of the prioritized locations the application checks for its configuration, following this order [1]: 1. The file path defined by the CMUX_TUI_CONFIG environment variable [1]. 2. The file path defined by the legacy CMUX_MUX_CONFIG environment variable [1]. 3. The standard configuration file at $XDG_CONFIG_HOME/cmux/cmux-tui.json or ~/.config/cmux/cmux-tui.json [1]. 4. An existing legacy mux.json file (used if cmux-tui.json is absent) [1]. To start a server (mux backend) using cmux-tui, you can run the application in headless mode [1]. This initializes the mux backend and control socket without launching the full TUI [1]. You can perform this using the following command [1]: cargo run -p cmux-tui -- --headless --session After starting the server, you can attach a TUI to that session from another terminal using [1]: cargo run -p cmux-tui -- attach --session If you are running a standard session, the application automatically starts an in-process mux, opens the TUI, and serves the control socket [1]. You can set the CMUX_TUI_CONFIG variable in your environment before running these commands to ensure the application loads your specific configuration file [1].

"CMUX_TUI_CONFIG" "server start" cmux-tui
💡 Result:
CMUX_TUI_CONFIG is an environment variable used to specify the configuration file path for cmux-tui, a terminal-based component of the cmux project [1][2]. When launching cmux-tui, the application determines its configuration path by checking the following locations in order of precedence: 1. The file path defined by the CMUX_TUI_CONFIG environment variable [1][2]. 2. The legacy CMUX_MUX_CONFIG environment variable [1][2]. 3. The XDG-compliant path: $XDG_CONFIG_HOME/cmux/cmux-tui.json (or ~/.config/cmux/cmux-tui.json if XDG_CONFIG_HOME is not set) [1][2]. 4. Existing legacy mux.json files [1][2]. Regarding the "server start cmux-tui" part of your query, cmux-tui is a separate component from the main macOS cmux terminal application [3][4][5]. While the main cmux application is a GUI-based Ghostty-powered terminal [3][5], cmux-tui refers to the TUI-based multiplexing component within the broader cmux project repository [1][4]. If you are attempting to configure the WebSocket server within cmux-tui, you can define the server settings in the JSON configuration file referenced by CMUX_TUI_CONFIG [1]. For example: { "server": { "ws": "127.0.0.1:7681", "ws_token": "your-static-token" } } This enables the WebSocket control listener, which is used for TUI pairing or headless server interactions [1]. Note that the WebSocket listener has no TLS; the documentation recommends using an authenticated TLS reverse proxy for remote access [1].

"state" "cmux-tui" "server stop" SQLite
💡 Result:
To stop the cmux-tui server, use the command: cmux-tui server stop [1][2] This command is the canonical way to shut down a running cmux-tui server [1]. It triggers a graceful shutdown process that stops the embedded listener, the local owner, and active workspaces, while also performing idempotent cleanup of stale socket connections [1][2]. Important considerations when stopping the server: - Process Termination: Stopping the server will exit all associated pane processes [2]. - Idempotency: The stop command is idempotent, meaning it will handle cases where the server is already absent without error [1]. - Context: If you are encountering issues attaching to a session, it is standard practice to run cmux-tui server status first to check the state, followed by cmux-tui server stop, before attempting to restart the binary [2]. Regarding SQLite, cmux-tui uses internal persistence mechanisms, but the stop command operates on the server's lifecycle rather than requiring direct interaction with underlying SQLite database files [1][2][3]. The server manages its own state and resources internally [1][4].

💡 Result:
The query you provided, CMUX_TUI_CONFIG workspace create, combines an environment variable configuration with a command-line interface (CLI) operation used for the cmux terminal [1][2]. CMUX_TUI_CONFIG is an environment variable used to specify the path to the cmux configuration file (typically cmux-tui.json) [3][4][1]. It allows you to override the default configuration path [4][1]. workspace create is a CLI command used to programmatically create a new workspace within cmux [2][5]. It is part of the cmux CLI and socket API, which allows for automation, scripting, and integration with other tools [2][5]. For example, to create a workspace while specifying a configuration file, you might use the following pattern in a terminal: CMUX_TUI_CONFIG=/path/to/your/cmux-tui.json cmux workspace create [options] The cmux CLI allows for various options when creating workspaces, such as defining names or backing the workspace with remote environments like SSH or containers [5][6]. You can refer to the official cmux CLI reference or run cmux workspace --help for a complete list of flags and options supported by your installed version [2].

💡 Result:
There is no single command named "CMUX_TUI_CONFIG server stop". Instead, CMUX_TUI_CONFIG is an environment variable used to specify the location of your configuration file [1][2]. To stop a server, you should use the cmux CLI command [3][4]. To stop a cmux-tui server, use the following command in your terminal: cmux server stop [--session ] [--socket ] [--force] [3] Key details regarding this command: - It is used for managing a named local durable session [3][4]. - The command is idempotent; if no server is running (or the socket is absent), it reports success [3][4]. - It performs a graceful shutdown by sending a process identity and generation-fenced operation [3]. - It stops the local owner and its workspaces, but it does not delete the durable topology [3][4]. Regarding the CMUX_TUI_CONFIG variable: - It is used to override the default configuration file location (which is typically ~/.config/cmux/cmux-tui.json or $XDG_CONFIG_HOME/cmux/cmux-tui.json) [1][2]. - If you need to stop a server that was started with a specific custom configuration, you generally do not need to reference that configuration file in the stop command itself, as the command targets the running session via the socket or session name [3].

🌐 Web query:
site:github.com/manaflow-ai/cmux "CMUX_TUI_CONFIG" "server start"
💡 Result:
CMUX_TUI_CONFIG is an environment variable used to specify the file path for the cmux-tui configuration, rather than a command to start a server [1][2]. To start a server in cmux-tui, you configure the server settings within your configuration file (e.g., cmux-tui.json). Specifically, you can set the server.ws key to a socket address string (such as 127.0.0.1:7681) to enable the WebSocket control listener [1]. The application resolves its configuration by checking the following locations in order [1][2]: 1. The path specified by the CMUX_TUI_CONFIG environment variable. 2. The path specified by the legacy CMUX_MUX_CONFIG environment variable (used as a fallback). 3. The default path: $XDG_CONFIG_HOME/cmux/cmux-tui.json or ~/.config/cmux/cmux-tui.json. 4. Legacy mux.json files are used if a cmux-tui.json file is absent. If you are attempting to configure the WebSocket server, ensure that the listener is bound to loopback unless you specifically use the --ws-insecure-bind flag [1]. Note that the listener does not support TLS natively; the documentation recommends using an authenticated TLS reverse proxy for remote access [1].

site:github.com/manaflow-ai/cmux/blob/main/cmux-tui/spec/cli.md "--state <path>" "--session <session>"
💡 Result:
The command-line arguments --state and --session are used by the cmux CLI tool [1]. In the context of cmux, these flags serve different purposes depending on the command: 1. --session : This is a routing option used to specify a particular session [1]. It helps determine which socket or instance of the tool to target when running commands like server status, stop, or reload-config [1]. 2. --state : This flag is used in specific subcommands, such as session reset-state, where it allows the user to specify a path for state-related operations [1]. Additionally, it appears in agent report commands, where it is used to define the state being reported [1]. For managing sessions, cmux uses --session to provide routing defaults, ensuring that commands are directed to the correct local socket [1]. The tool also supports an explicit --socket option, which takes precedence over --session [1].

site:github.com/manaflow-ai/cmux/blob/main/cmux-tui/spec/cli.md "workspace create" "--session"
💡 Result:
The command workspace create --session is part of the command-line interface for cmux-tui, a tool designed for managing multiplexed terminal sessions [1]. In this context, the --session flag is used to define routing defaults for the workspace being created [1]. Specifically, cmux-tui determines which local socket to target based on a hierarchy of precedence: an explicit --socket flag takes the highest priority, followed by an explicit --session flag, then inherited environment variables (CMUX_TUI_SOCKET or CMUX_MUX_SOCKET), and finally the default main session [1]. By providing --session, you ensure that the workspace creation is routed to the specified session, preventing it from inheriting a socket from a different session [1]. More generally, the workspace create command is used to initialize a new workspace, which by default starts with one terminal unless the --empty flag is specified [1]. Additionally, commands involving workspace creation support an optional --correlation-key for idempotency [1]. If a creation process is interrupted, you may need to use the session creation resolve command before attempting to create the workspace again [1].

💡 Result:
Session state refers to the data maintained by an application to track individual user interactions across multiple requests, ensuring continuity and personalization throughout a session. Application support for session state typically involves mechanisms to store, manage, and retrieve this data, often utilizing directories like the platform-specific Application Support folders on operating systems (e.g., macOS: ~/Library/Application Support/cmux-tui/sessions) or database systems like SQLite for persistence [1]. In software architecture, session state is distinct from application state; the former is user-specific and temporary, while the latter is global and shared across all users [1]. Effective session management often employs persistent storage to prevent data loss, utilizing techniques such as exclusive write leases, Write-Ahead Logging (WAL), and strict synchronization to maintain data integrity and prevent concurrency conflicts [1]. Applications may also offer options to store session data in-memory for ephemeral, non-persistent requirements, which are typically mutually exclusive with disk-based state storage [1].

Correct the state-isolation guidance.
--state <path> is not a general state-root option for server start, workspace mutations, or server stop. --session <name> routes commands to a session but does not configure a separate state root. Document the supported state mechanism and require consistent --session, --socket, or socket environment settings.

guidance in the getting-started documentation to remove the claim that --state

Greptile SummaryThis docs-only PR adds guidance for products built on cmux-tui to own dedicated, instance-specific sessions.
Confidence Score: 5/5The PR appears safe to merge because the documented session-isolation guidance and command examples agree with the current CLI and state-layout behavior. The changes affect documentation only, and investigation found no incorrect command, broken documentation contract, or misleading isolation guidance. Important Files Changed

Agents and programs that build isolated products on top of cmux-tui (agent orchestrators, test harnesses, firstmate-style crews) were given no guidance on session ownership, so the natural failure mode is squatting the shared `main` session or a person's interactive session.
This adds an "Isolated products on top of cmux-tui" section to `docs/getting-started.md`: one dedicated session per product instance, product+instance session naming, addressing by `--session`/`--socket`, storing typed IDs instead of display names, `CMUX_TUI_CONFIG` for config isolation, and when `--state` is actually needed. Also advertises the section from the docs index.
