+# Documentation Automation
+
+This directory contains automated pipelines for keeping goose documentation synchronized with code changes.
+
+## Overview
+
+Each automation project tracks specific types of changes and updates corresponding documentation:
+
+| Project | Status | Tracks | Updates |
+|---------|--------|--------|---------|
+| [recipe-schema-tracking](./recipe-schema-tracking/) | ✅ Active | Recipe schema & validation rules | Recipe Reference Guide |
+| cli-command-tracking | 🔮 Planned | CLI commands & options | CLI documentation |
+| provider-tracking | 🔮 Planned | Supported AI providers | Provider documentation |
+| extension-tracking | 🔮 Planned | Built-in extensions | Extension documentation |
+
+## Architecture
+
+Each automation project follows a consistent pattern:
+
+```
+project-name/
+├── README.md             # Project-specific documentation
+├── TESTING.md            # How to test this automation
+├── config/               # Configuration files
+├── scripts/              # Deterministic extraction/diff scripts
+└── recipes/              # AI-powered synthesis/update recipes
+```
+
+### Design Principles
+
+1. **Modular**: Each project is self-contained
+2. **Testable**: Clear inputs/outputs at each stage
+3. **Transparent**: Intermediate files can be inspected
+4. **Reusable**: Common patterns across projects
+
+### Hybrid Approach
+
+- **Shell scripts**: Deterministic extraction and comparison
+- **AI recipes**: Synthesis and documentation updates
+
+## GitHub Actions Integration
+
+Automation projects can be triggered via GitHub Actions workflows in `.github/workflows/`.
+
+See individual project TESTING.md files for workflow usage.
+
+## Adding New Automations
+
+When creating a new automation project:
+
+1. Create a subdirectory: `documentation/automation/your-project/`
+2. Follow the standard structure (README, TESTING, config, scripts, recipes)
+3. Create corresponding GitHub Actions workflow (if needed)
+4. Update this README with the new project
+
+## Questions?
+
+For project-specific questions, see the README in each project directory.

+# Recipe Schema Tracking
+
+Automated pipeline for detecting and documenting Recipe schema and validation rule changes between goose releases.
+
+## Overview
+
+This automation keeps the [Recipe Reference Guide](https://block.github.io/goose/docs/guides/recipes/recipe-reference) synchronized with code changes by:
+
+1. **Extracting** schema and validation rules from source code (deterministic)
+2. **Detecting** changes between versions (deterministic diff)
+3. **Synthesizing** human-readable change documentation (AI-powered)
+4. **Updating** the Core Recipe Schema, Field Specifications, and Validation Rule sections in the Recipe Reference Guide (AI-powered)
+
+The automation runs automatically on new releases via GitHub Actions, or can be run manually for testing.
+
+## Quick Start
+
+### Automated (GitHub Actions)
+
+The automation runs automatically when a new release is published. See [TESTING.md](./TESTING.md) for testing instructions.
+
+### Manual (Local Testing)
+
+```bash
+# Run the complete pipeline
+./scripts/run-pipeline.sh v1.14.0 v1.15.0
+
+# Or run individual steps:
+# 1. Extract validation structures
+./scripts/extract-validation-structure.sh v1.14.0 > output/old-validation-structure.json
+./scripts/extract-validation-structure.sh v1.15.0 > output/new-validation-structure.json
+
+# 2. Extract schemas
+./scripts/extract-schema.sh v1.15.0 > output/new-schema.json
+
+# 3. Detect changes
+./scripts/diff-validation-structures.sh output/old-validation-structure.json \
+                                        output/new-validation-structure.json \
+                                        > output/validation-changes.json
+
+# 4. Generate human-readable change documentation
+cd output && goose run --recipe ../recipes/synthesize-validation-changes.yaml
+
+# 5. Update recipe-reference.md
+export RECIPE_REF_PATH=/path/to/recipe-reference.md
+goose run --recipe ../recipes/update-recipe-reference.yaml
+```
+
+## Architecture
+
+### Modular Pipeline Design
+
+The automation uses a **hybrid approach**: deterministic shell scripts for data extraction/diffing, AI recipes for analysis and documentation updates.

+
+### Why This Design?
+
+**Scripts handle deterministic tasks:**
+- Version-specific code extraction using `git show`
+- JSON schema parsing and comparison
+- No interpretation or inference - direct text extraction
+
+**AI recipes handle synthesis and updates:**
+- Analyzing changes and explaining implications
+- Generating migration guidance and examples
+- Updating documentation with proper formatting and context
+
+**Benefits:**
+- **Reliability**: Extraction is deterministic and reproducible
+- **Testability**: Each stage has clear inputs/outputs
+- **Maintainability**: Easy to update individual components
+- **Transparency**: Intermediate files can be inspected
+
+### Data Flow
+
+All stages communicate via JSON/Markdown files in the `output/` directory:
+
+| File | Producer | Consumer | Purpose |
+|------|----------|----------|---------|
+| `old-schema.json` | `extract-schema.sh` | `synthesize-validation-changes.yaml` | Previous version OpenAPI schema |
+| `new-schema.json` | `extract-schema.sh` | `synthesize-validation-changes.yaml` | Current version OpenAPI schema |
+| `old-validation-structure.json` | `extract-validation-structure.sh` | `diff-validation-structures.sh` | Previous version struct fields + validation functions |
+| `new-validation-structure.json` | `extract-validation-structure.sh` | `diff-validation-structures.sh` | Current version struct fields + validation functions |
+| `validation-changes.json` | `diff-validation-structures.sh` | `synthesize-validation-changes.yaml` | Detected changes (structured) |
+| `validation-changes.md` | `synthesize-validation-changes.yaml` | `update-recipe-reference.yaml` | Human-readable change documentation |
+| `update-summary.md` | `update-recipe-reference.yaml` | Human review | Summary of documentation updates |
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| `RECIPE_REF_PATH` | No | - | Full path to `recipe-reference.md` file (overrides `GOOSE_REPO` construction) |
+| `GOOSE_REPO` | No | Auto-detect | Path to goose repository root |
+
+**Example (for local testing):**
+```bash
+export RECIPE_REF_PATH=/path/to/local/goose/documentation/docs/guides/recipes/recipe-reference.md
+# OR
+export GOOSE_REPO=/path/to/local/goose
+```
+
+### Configuration Files
+
+#### `config/serde-attributes.json`
+
+Defines Serde attribute meanings for parsing struct fields:
+
+```json
+{
+  "skip_serializing_if": "Field is optional and skipped when value matches condition",
+  "default": "Field uses default value when missing during deserialization",
+  "flatten": "Field's contents are flattened into parent struct",
+  "rename": "Field is serialized with a different name"
+}
+```
+
+**When to update:** When new Serde attributes are introduced in Recipe struct definitions.
+
+#### `config/known-validation-files.json`
+
+Lists source files containing recipe validation logic:
+
+```json
+{
+  "validation_files": [
+    "crates/goose/src/recipe/validate_recipe.rs",
+    "crates/goose/src/agents/types.rs"
+  ]
+}
+```
+
+**When to update:** When validation logic is added to new files or moved to different locations.
+
+### Scope and Exclusions
+
+#### In Scope
+- Top-level Recipe struct fields (all fields in `Recipe` struct)
+- Validation functions in `validate_recipe.rs`
+- Field types, optionality, and default values
+- Validation error messages and requirements
+- Enum value changes (e.g., new input types)
+
+#### Excluded (By Design)
+- **Extension schema deep-dives**: Extensions use a dual-purpose type (`ExtensionConfig`) shared across recipes, CLI, and runtime with mismatched validation requirements. The automation documents basic structure only. Extension-specific validation is documented separately.
+
+**Why extensions are excluded:** The `ExtensionConfig` type serves multiple contexts with different validation needs:
+- **Recipe context**: Looser validation for user-authored configurations
+- **CLI context**: Stricter validation for command-line arguments
+- **Runtime context**: Additional validation for server connections
+
+Attempting to document all extension validation rules in the Recipe Reference would create confusion about which rules apply when. Extension documentation is maintained separately.
+
+## Scripts
+
+### `extract-schema.sh`
+
+Extracts OpenAPI schema from the goose codebase.
+
+**Usage:**
+```bash
+./scripts/extract-schema.sh [version] > output/new-schema.json
+```
+
+**Arguments:**
+- `version` (optional): Git tag or commit to extract from (default: current working directory)
+
+**Output:** JSON schema with field descriptions, types, and constraints
+
+**Example:**
+```bash
+# Extract from current code
+./scripts/extract-schema.sh > output/new-schema.json
+
+# Extract from specific version
+./scripts/extract-schema.sh v1.15.0 > output/old-schema.json
+```
+
+### `extract-validation-structure.sh`
+
+Extracts Recipe struct fields and validation functions from source code.
+
+**Usage:**
+```bash

+```
+
+**Arguments:**
+- `version` (optional): Git tag or commit to extract from (default: current working directory)
+
+**Output:** JSON with struct fields (name, type, optionality, comments) and validation functions (signature, error messages)
+
+**Example:**
+```bash
+# Extract from current code
+./scripts/extract-validation-structure.sh > output/new-validation-structure.json
+
+# Extract from v1.15.0
+./scripts/extract-validation-structure.sh v1.15.0 > output/old-validation-structure.json
+```
+
+### `diff-validation-structures.sh`
+
+Compares two validation structure files and outputs detected changes.
+
+**Usage:**
+```bash
+./scripts/diff-validation-structures.sh <old-file> <new-file> > output/validation-changes.json
+```
+
+**Arguments:**
+- `old-file`: Path to old validation structure JSON
+- `new-file`: Path to new validation structure JSON
+
+**Output:** JSON with categorized changes:

+- `struct_fields.comment_changed`: Comment updates
+- `validation_functions.added`: New validation rules
+- `validation_functions.removed`: Deleted validation rules
+
+**Example:**
+```bash
+./scripts/diff-validation-structures.sh \
+  output/old-validation-structure.json \

+goose run --recipe ../recipes/synthesize-validation-changes.yaml
+```
+
+**What it does:**
+- Compares old and new schemas to detect enum changes and required field changes
+- Analyzes struct field changes (additions, removals, type changes)
+- Explains validation rule changes with examples

+
+## GitHub Actions Workflow
+
+The automation runs via `.github/workflows/docs-update-recipe-ref.yml`:
+
+- **Trigger**: Automatically on new releases, or manually for testing
+- **Process**: Extracts schemas, detects changes, updates documentation
+- **Output**: Creates a PR with updated `recipe-reference.md` if changes detected
+- **Testing**: See [TESTING.md](./TESTING.md) for detailed testing instructions
+
+## What Gets Tracked
+
+### Struct Fields (6 structs)
+- `Recipe` - Top-level recipe structure
+- `Author` - Recipe author information  
+- `Settings` - Recipe settings (model, provider, etc.)
+- `Response` - Structured output schema
+- `SubRecipe` - Sub-recipe definitions
+- `RecipeParameter` - Parameter definitions
+
+### Changes Detected
+- ✅ Fields added/removed
+- ✅ Field type changes (e.g., `Option<T>` → `T`)
+- ✅ Comment changes (inline documentation)
+- ✅ Validation functions added/removed/modified
+- ✅ Error messages changed
+- ✅ Enum value changes
+
+## Maintenance
+
+When modifying the automation:
+
+1. **Test locally first**: Run `./scripts/run-pipeline.sh` with test versions
+2. **Verify outputs**: Check generated files against source code
+3. **Update configuration**: If validation files move or new attributes added
+4. **Test in fork**: Use GitHub Actions workflow with dry-run mode
+5. **Document changes**: Update this README with design decisions

+# Testing Recipe Schema Tracking Automation
+
+This guide covers how to test the recipe schema tracking automation both locally and via GitHub Actions.
+
+## Local Testing
+
+### Prerequisites
+
+- goose CLI installed
+- jq installed (for JSON processing)
+- Git repository with goose source code
+
+### Manual Pipeline Execution
+
+Test the complete pipeline locally:
+
+```bash
+cd documentation/automation/recipe-schema-tracking
+
+# Test with no changes expected
+./scripts/run-pipeline.sh v1.14.0 v1.15.0
+
+# Test with changes expected
+./scripts/run-pipeline.sh v1.9.0 v1.15.0
+```
+
+### Individual Script Testing
+
+Test each script independently:
+
+```bash
+# Extract schema from a version
+./scripts/extract-schema.sh v1.15.0 > output/test-schema.json
+
+# Extract validation structure
+./scripts/extract-validation-structure.sh v1.15.0 > output/test-validation.json
+
+# Compare two validation structures
+./scripts/diff-validation-structures.sh output/old.json output/new.json > output/test-changes.json
+```
+
+### Recipe Testing
+
+Test the AI recipes:
+
+```bash
+# Generate change documentation
+cd output
+goose run --recipe ../recipes/synthesize-validation-changes.yaml
+
+# Update recipe-reference.md
+export RECIPE_REF_PATH=/path/to/recipe-reference.md
+goose run --recipe ../recipes/update-recipe-reference.yaml
+```
+
+## GitHub Actions Testing
+
+### Test in Your Fork
+
+The workflow can be tested in your fork without affecting the upstream repository.
+
+#### Step 1: Push Branch to Fork
+
+```bash
+git push origin your-branch-name
+```
+
+#### Step 2: Enable GitHub Actions
+
+1. Go to your fork on GitHub
+2. Click "Actions" tab
+3. Enable workflows if prompted
+
+#### Step 3: Run Workflow Manually
+
+1. Click "Update Recipe Documentation" workflow (docs-update-recipe-ref.yml)
+2. Click "Run workflow" button
+3. Select your branch
+4. Configure inputs (see test scenarios below)
+5. Click "Run workflow"
+
+### Test Scenarios
+
+#### Scenario 1: Dry-Run with No Changes
+
+**Purpose**: Verify the workflow runs successfully when no changes are detected.
+
+**Inputs**:
+- `old_version`: `v1.14.0`
+- `new_version`: `v1.15.0`
+- `dry_run`: `true`
+
+**Expected Results**:
+- ✅ Workflow completes successfully
+- ✅ "No changes detected" message in summary
+- ✅ Artifacts uploaded with extraction results
+- ✅ No PR created
+
+#### Scenario 2: Dry-Run with Changes
+
+**Purpose**: Test change detection and documentation generation without creating a PR.
+
+**Inputs**:
+- `old_version`: `v1.9.0`
+- `new_version`: `v1.15.0`
+- `dry_run`: `true`
+
+**Expected Results**:
+- ✅ Workflow detects changes (4 validation rules, 1 field removal)
+- ✅ Generates `validation-changes.md` with documentation
+- ✅ Updates `recipe-reference.md`
+- ✅ Artifacts uploaded with all generated files
+- ✅ No PR created (dry-run mode)
+
+**Review Artifacts**:
+1. Download artifact zip from workflow run
+2. Check `validation-changes.md` - should document all changes
+3. Check `update-summary.md` - should show what was updated
+4. Compare updated `recipe-reference.md` with original
+
+#### Scenario 3: Full Run with PR Creation
+
+**Purpose**: Test end-to-end including PR creation.
+
+**Inputs**:
+- `old_version`: `v1.9.0`
+- `new_version`: `v1.15.0`
+- `dry_run`: `false`
+
+**Expected Results**:
+- ✅ Workflow runs successfully
+- ✅ Creates PR: `docs/recipe-reference-v1.15.0`
+- ✅ PR contains updated `recipe-reference.md`
+- ✅ PR description includes change summary and checklist
+
+**Review PR**:
+1. Check only `recipe-reference.md` was modified
+2. Verify changes match dry-run artifacts
+3. Confirm no unintended modifications
+4. Test documentation renders correctly
+
+#### Scenario 4: Auto-Detection
+
+**Purpose**: Test automatic version detection (simulates production mode).
+
+**Inputs**:
+- `old_version`: *(leave empty)*
+- `new_version`: *(leave empty)*
+- `dry_run`: `true`
+
+**Expected Results**:
+- ✅ Auto-detects two most recent releases
+- ✅ Compares them automatically
+- ✅ Uploads artifacts
+
+### Reviewing Workflow Results
+
+#### Check Workflow Summary
+
+Each workflow run provides a summary with:
+- Version comparison performed
+- Whether changes were detected
+- Dry-run mode status
+- Links to artifacts
+
+#### Download and Review Artifacts
+
+Artifacts include:
+- `old-validation-structure.json` - Extracted from old version
+- `new-validation-structure.json` - Extracted from new version
+- `validation-changes.json` - Structured diff
+- `validation-changes.md` - Human-readable changes
+- `update-summary.md` - Documentation update summary
+- `pipeline.log` - Full pipeline execution log
+
+#### Check Workflow Logs
+
+For detailed debugging:
+1. Click on the workflow run
+2. Click on the "Update Recipe Documentation" job
+3. Expand each step to see detailed logs
+4. Look for error messages or unexpected behavior
+
+## Troubleshooting
+
+### Workflow doesn't appear in Actions tab
+
+- Verify workflow file is in `.github/workflows/`
+- Check file has `.yml` or `.yaml` extension
+- Ensure GitHub Actions is enabled in fork
+
+### "No changes detected" when expecting changes
+
+- Check artifact `validation-changes.json` to see what was compared
+- Verify versions exist: `git tag | grep v1.15.0`
+- Review extraction script logs
+
+### goose CLI installation fails
+
+- Workflow installs from current repository
+- Ensure `crates/goose-cli` builds successfully
+- Check Rust toolchain installation
+
+### PR creation fails
+
+- Verify workflow has required permissions
+- Check branch name doesn't already exist
+- Review workflow logs for error messages
+
+## Production Deployment
+
+Once testing is complete:
+
+1. **Merge automation to main**: Create PR for `documentation/automation/recipe-schema-tracking/`
+2. **Merge baseline docs**: Create PR for revised `recipe-reference.md`
+3. **Merge workflow**: Create PR for `.github/workflows/docs-update-recipe-ref.yml`
+4. **Enable release trigger**: Uncomment `release:` section in workflow
+
+After deployment, the workflow will automatically:
+- Trigger on new releases
+- Compare with previous release
+- Create PR if changes detected
+- Notify team for review

+title: "Synthesize Validation Changes"
+description: "Generate human-readable documentation for validation rule changes between two versions"
+
+extensions:
+  - type: builtin
+    name: developer
+
+instructions: |
+  You are a technical documentation specialist creating release notes for Recipe validation changes.
+  
+  ## Your Task
+  
+  Analyze the validation changes between two goose versions and generate clear, user-focused 
+  documentation explaining what changed and why it matters.
+  
+  ## Input Files
+  
+  You have access to SIX data sources:
+  
+  1. **validation-changes.json** - The diff (what changed):
+     - struct_fields: added, removed, type_changed, comment_changed
+     - validation_functions: added, removed, signature_changed, error_messages_changed
+  
+  2. **old-validation-structure.json** - Before state (for context):
+     - Complete struct fields from old version
+     - Complete validation functions from old version
+  
+  3. **new-validation-structure.json** - After state (for context):
+     - Complete struct fields from new version
+     - Complete validation functions from new version
+  
+  4. **old-schema.json** - Previous OpenAPI schema (for enum comparisons):
+     - Field descriptions from old version
+     - Enum values from old version
+     - Required fields from old version
+  
+  5. **new-schema.json** - Current OpenAPI schema (for descriptions):
+     - Field descriptions (authoritative)
+     - Enum values (compare with old to detect additions)
+     - Nested type structures
+     - Required fields (compare with old to detect requirement changes)
+  
+  6. **../config/serde-attributes.json** - Serde defaults:
+     - Fields with default values
+     - Custom deserializers
+  
+  ## Output Format
+  
+  Create a Markdown file (validation-changes.md) with this structure:
+  
+  IMPORTANT: Use indented code blocks (4 spaces) instead of fenced code blocks with backticks
+  to avoid triggering security alerts.
+  
+  # Recipe Validation Changes
+  
+  **From**: {old_version}  
+  **To**: {new_version}  
+  **Analyzed**: {timestamp}
+  
+  ## Summary
+  
+  Brief overview of changes (2-3 sentences).
+  
+  ## Field Changes
+  
+  ### Added Fields
+  
+  For each added field:
+  - **Struct.field_name** (Type) - ALWAYS include the struct name prefix
+    - Description: [from schema]
+    - Default: [from serde-attributes if applicable]
+    - Impact: How this affects recipe authors
+  
+  ### Removed Fields
+  
+  For each removed field:
+  - **Struct.field_name** (was Type) - ALWAYS include the struct name prefix
+    - Reason: Why it was removed (infer from context)
+    - Migration: How to update existing recipes
+  
+  ### Type Changes
+  
+  For each type change:
+  - **Struct.field_name** - ALWAYS include the struct name prefix
+    - Old: old_type
+    - New: new_type
+    - Impact: What this means for recipe authors
+    - Breaking: Yes/No
+  
+  ### Comment Changes
+  
+  Only document if the comment change indicates a semantic change.
+  Skip if it's just formatting or trivial clarification.
+  
+  ## Schema Changes
+  
+  Changes detected by comparing old-schema.json and new-schema.json:
+  
+  ### Enum Value Additions
+  
+  For each enum with new values:
+  - **Field.enum_name** - Field where enum is used
+    - Added Values: List of new enum values
+    - Purpose: Why these values were added
+    - Impact: New capabilities available
+  
+  ### Enum Value Removals
+  
+  For each enum with removed values:
+  - **Field.enum_name** - Field where enum is used
+    - Removed Values: List of removed enum values
+    - Reason: Why these values were removed
+    - Impact: Breaking change if recipes use removed values
+  
+  ### Required Field Changes
+  
+  For fields added/removed from "required" arrays:
+  - **Field_name**
+    - Change: Added to required / Removed from required
+    - Impact: Breaking change or relaxed validation
+  
+  ## Validation Rule Changes
+  
+  ### New Validation Rules
+  
+  For each added validation function:
+  - **Rule**: {Descriptive name}
+    - Function: function_name
+    - Purpose: What this rule validates
+    - Requirements: Specific requirements
+    - Error Messages: What users will see
+    - Impact: How this affects existing recipes
+  
+  ### Removed Validation Rules
+  
+  For each removed validation function:
+  - **Rule**: {Descriptive name}
+    - Function: function_name
+    - Reason: Why it was removed
+    - Impact: What recipes are now allowed
+  
+  ### Changed Validation Rules
+  
+  For signature or error message changes:
+  - **Rule**: {Descriptive name}
+    - Function: function_name
+    - What Changed: Specific changes
+    - Impact: How this affects recipe authors
+  
+  ## Breaking Changes
+  
+  List all breaking changes with migration guidance:
+  - Change description
+  - How to update recipes
+  - Example before/after (use indented code blocks)
+  
+  ## Non-Breaking Changes
+  
+  List all non-breaking changes (new optional fields, relaxed validation, etc.)
+  
+  ## Analysis Guidelines
+  
+  1. **ALWAYS Include Struct Context**: Every field change MUST include the struct name
+     - Read the "struct" field from validation-changes.json
+     - Format as **Struct.field** (e.g., **Recipe.context**, **SubRecipe.description**)
+     - This is CRITICAL because multiple structs can have fields with the same name
+     - Example: Both Recipe and SubRecipe have a "description" field
+  
+  2. **Detect Schema-Only Changes**: Compare old-schema.json and new-schema.json for:
+     - **Enum additions**: New values added to enum fields (e.g., input_type: "multiselect")
+     - **Enum removals**: Values removed from enum fields
+     - **Required field changes**: Fields added/removed from "required" arrays
+     - **Extension type changes**: New extension types in the extensions oneOf array
+     - Document these in a separate "Schema Changes" section
+  
+  3. **Focus on User Impact**: Explain changes from recipe author perspective
+  
+  4. **Prioritize Breaking Changes**: Highlight anything that breaks existing recipes
+  
+  5. **Use Context**: Use old and new structures to understand relationships
+     - Example: If "context" field removed, check if functionality moved elsewhere
+  
+  6. **Infer Intent**: Use function names, error messages, and field types to understand why changes were made
+  
+  7. **Be Specific**: Include concrete examples of what changed
+  
+  8. **Skip Noise**: Don't document trivial comment formatting changes
+  
+  9. **Use Schema Descriptions**: Prefer schema descriptions over inline comments
+  
+  10. **Document Defaults**: Note when fields have serde defaults from config
+  
+  ## Security Scanner Constraints
+  
+  CRITICAL: The security scanner flags backticks as command substitution. You MUST NEVER use them:
+  
+  1. **NO BACKTICKS ANYWHERE**:
+     - NOT in inline code: Write **field_name** instead
+     - NOT around field names: Write **context** not with backticks
+     - NOT in code blocks: Use 4-space indentation only
+     - NOT in any text: Even mentioning backticks triggers alerts
+  
+  2. **NO SHELL PATTERNS**:
+     - No "2>/dev/null", "rm -f", "rm -rf"
+     - No file deletion examples
+     - No shell redirections
+  
+  3. **Safe Alternatives**:
+     - Field names: Use **bold** (e.g., **context**, **description**)
+     - Code blocks: Use 4-space indentation
+     - Types: Write plain text (e.g., "Option of String")
+     - Functions: Use **bold** (e.g., **validate_json_schema**)
+  
+  Examples:
+  - ❌ NEVER: Any use of the backtick character
+  - ✅ ALWAYS: **bold** for emphasis, 4-space indented blocks for code
+  
+  ## Special Cases
+  
+  - **Empty changes arrays**: If a category has no changes, skip that section entirely
+  
+  - **Context field removal**: This is the "context" field we discussed - it was never documented
+  
+  - **Validation functions with no error messages**: Function likely returns early with Ok or uses inline checks
+  
+  ## File Locations
+  
+  - Input 1: ./validation-changes.json (the diff)
+  - Input 2: ./old-validation-structure.json (before state)
+  - Input 3: ./new-validation-structure.json (after state)
+  - Input 4: ./old-schema.json (previous schema for comparison)
+  - Input 5: ./new-schema.json (current schema with descriptions)
+  - Input 6: ../config/serde-attributes.json (defaults)
+  - Output: ./validation-changes.md
+  
+  Start by reading all SIX input files, then generate the validation changes documentation.
+
+prompt: |
+  Please analyze the validation changes and generate comprehensive release notes.
+  
+  Steps:
+  1. Read all SIX input files (validation-changes.json, old/new-validation-structure.json, old/new-schema.json, serde-attributes.json)
+  2. Analyze the changes
+  3. Write the documentation to ./validation-changes.md using the text_editor tool
+  
+  Focus on:
+  - User impact (how does this affect recipe authors?)
+  - Breaking vs non-breaking changes
+  - Migration guidance for breaking changes
+  - Schema-only changes (enum additions, required field changes)
+  - Clear, actionable documentation
+  
+  IMPORTANT: You MUST use the text_editor tool to write the output to ./validation-changes.md

+version: "2"
+title: "Update Recipe Reference Documentation"
+description: "Apply validation changes to recipe-reference.md based on validation-changes.md"
+
+extensions:
+  - type: builtin
+    name: developer
+
+instructions: |
+  You are a technical documentation specialist updating the Recipe Reference Guide with schema and validation rule changes.
+  
+  ## ⚠️ CRITICAL RULES
+  
+  1. **Only Update What's Documented**: If a field, rule, or section is NOT mentioned in validation-changes.md, DO NOT touch it
+  2. **Verify Before Removing**: Before removing any field or section, double-check it's explicitly listed as "removed" in validation-changes.md
+  3. **Preserve Everything Else**: All other content, formatting, examples, and sections must remain exactly as-is
+  4. **Table Updates - Use Precise str_replace**: When removing a row from a markdown table:
+     - Use old_str/new_str (NOT diff format)
+     - Include the COMPLETE row you want to remove
+     - Include 1-2 rows before and after for context
+     - Verify your old_str matches EXACTLY what's in the file
+     - Double-check you're not accidentally removing adjacent rows
+  
+  ## Your Task
+  
+  You will update THREE main areas in recipe-reference.md:
+  1. **Core Recipe Schema table** - Field additions, removals, and requirement changes
+  2. **Field Specifications sections** - Add/remove/update detailed field documentation
+  3. **Validation Rules section** - New, removed, or changed validation rules
+  4. **Maintain Consistency**
+     - Match the existing documentation style and tone
+     - Use the same formatting (bullet points, bold text, etc.)
+     - Keep language user-focused and actionable
+     - Maintain alphabetical or logical ordering within subsections
+
+  ## Input Files
+  
+  1. **validation-changes.md** - The change documentation from the pipeline:
+     - Located at: `./validation-changes.md`
+     - Contains: Field changes, new validation rules, breaking changes, migration guidance
+  
+  2. **recipe-reference.md** - The target documentation file:
+     - Located at: `${RECIPE_REF_PATH}` (environment variable)
+     - Default: `${GOOSE_REPO}/documentation/docs/guides/recipes/recipe-reference.md`
+     - Contains: Complete recipe reference with Validation Rules section
+  
+  3. **update-summary.md** - Output file for change summary:
+     - Located at: `./update-summary.md`
+     - You will create this file to document what was updated
+  
+  ## Target Sections
+  
+  ### Section 1: Core Recipe Schema table
+  
+  Find the **## Core Recipe Schema** section.
+  
+  This table lists all Recipe fields with:
+  - Field name
+  - Required (✅) or Optional (-)
+  - Default value
+  - Description
+  
+  **Important**: Character limits, required/optional status, and type information belong in this table, NOT in Validation Rules.
+  
+  ### Section 2: Field Specifications
+  
+  Find the **## Field Specifications** section.
+  
+  This section contains detailed documentation for complex fields (like activities, extensions, parameters, etc.).
+  
+  Each field specification typically includes:
+  - Schema table (if the field has sub-fields)
+    - Field name
+    - Type
+    - Required (✅) or Optional (-)
+    - Default value
+    - Description
+  - Description and usage notes
+  - Examples
+  - Special considerations
+  
+  ### Section 3: Validation Rules
+  
+  Find the **## Validation Rules** section.
+  
+  **Critical**: This section should ONLY document validation functions from `validate_recipe.rs`, NOT schema requirements.
+  
+  The section should:
+  - List only actual validation functions (with function names)
+  - Link to the source code
+  - Direct readers to the schema table for field requirements
+  
+  ## Update Strategy
+  
+  ### 1. Read and Analyze
+  
+  Read `validation-changes.md` completely and identify ALL changes documented.
+
+  **CRITICAL**: Only make changes that are explicitly documented in validation-changes.md. If a field/rule is not mentioned, DO NOT modify it.
+
+  ### 2. Apply Updates
+  
+  For each change documented in validation-changes.md, apply the corresponding update using this guide:
+
+  | Change Type | Where to Update | How to Update |
+  |-------------|-----------------|---------------|
+  | **Field added** | Core Schema table | Add new row with Field name, Required (✅/-), Default, Description. Maintain alphabetical order. Use information from validation-changes.md. |
+  | | Field Specifications | If complex field (objects, arrays of objects, enums): Add new section following pattern of similar fields. Include schema table, description, examples. |
+  | **Field removed** | Core Schema table | Delete the row for this field. **IMPORTANT**: Use str_replace with old_str containing the row to remove PLUS 1-2 surrounding rows for context. Verify you're only removing the intended row. |
+  | | Field Specifications (top-level) | If the removed field has its own section: Remove entire section. |
+  | | Field Specifications (nested) | If the removed field is within another field's section: Update that section's schema table to remove the field row. Review section for any other references to the removed field. |
+  | **Field renamed** | Core Schema table | Delete old name row, add new name row (appears as remove + add in validation-changes.md). |
+  | | Field Specifications | Update section header and references if section exists. |
+  | **Type changed** | Core Schema table | Update Type column. If optionality changed: update Required (✅ ↔ -) and Default columns. Update Description if the change affects field behavior. |
+  | | Field Specifications | Update section to reflect type change if section exists. |
+  | **Field description changed (if semantically significant)** | Core Schema table | Update Description column. |
+  | **Enum value added/removed** | Field Specifications | Update enum lists (e.g., Input Types list in Parameters section). |
+  | **Validation rule added** | Validation Rules | Add bullet point with description and function name in parentheses. Add to appropriate subsection (Recipe-Level or Parameter Validation). Follow existing format. |
+  | **Validation rule removed** | Validation Rules | Remove the bullet point. |
+  | **Validation rule modified** | Validation Rules | Update bullet point text to reflect new requirements. |
+
+  **Important Notes:**
+  - Simple fields (strings, booleans, simple arrays) do NOT need Field Specification sections
+  - Complex fields (objects, arrays of objects, enums with options) DO need Field Specification sections
+  - Look at existing Field Specifications to see which fields have detailed sections
+  - Match the structure and style of existing sections when adding new ones
+
+  ### 3. Verification
+
+  **Before finalizing:**
+  1. Review validation-changes.md one more time
+  2. Verify the changes you made to recipe-reference.md match the changes in validation-changes.md
+  3. Confirm you did NOT modify any field/rule that was not mentioned in validation-changes.md
+  4. Check that alphabetical ordering is maintained in tables
+
+
+  ## Output Requirements
+  
+  ### 1. Updated recipe-reference.md
+  
+  Update THREE areas as detailed in validation-changes.md:
+  - **## Core Recipe Schema** - Core Structure table (for field changes)
+  - **## Field Specifications** - Add/remove/update sections for complex fields
+  - **## Validation Rules** - All subsections (for validation rule changes)
+  
+  Do NOT change other sections. Preserve all formatting, headers, and structure.
+  
+  ### 2. Create update-summary.md
+  
+  Generate a summary document with this structure:
+  
+  ```markdown
+  # Recipe Reference Update Summary
+  
+  **Date**: {current_date}
+  **Source**: validation-changes.md (v1.9.0 → v1.15.0)
+  **Target**: recipe-reference.md
+  
+  ## Changes Applied
+  
+  ### Structural Requirements
+  - Added: {list new fields}
+  - Modified: {list changed fields}
+  - Removed: {list removed fields}
+  
+  ### Parameter Validation
+  - Added: {list new rules}
+  - Modified: {list changed rules}
+  - Removed: {list removed rules}
+  
+  ### [Other Subsections]
+  ...
+  
+  ## Sections Not Modified
+  
+  - {list subsections that didn't need changes}
+  
+  ## Verification Checklist
+  
+  - [ ] All new validation rules from validation-changes.md are documented
+  - [ ] Removed rules are no longer present
+  - [ ] Language matches existing documentation style
+  - [ ] Markdown formatting is valid
+  - [ ] No unintended changes to other sections
+  
+  ## Next Steps
+  
+  1. Review the updated Validation Rules section
+  2. Verify accuracy against source code if needed
+  3. Commit changes to the recipe-reference-updates branch
+  4. Create PR for review
+  ```
+  
+  ## Guidelines
+  
+  1. **Only Update What Changed**: CRITICAL - Only make changes that are documented in validation-changes.md
+     - Do NOT add "improvements" or "clarifications" not in the source
+     - Do NOT reorganize existing content
+     - Do NOT rewrite descriptions unless they changed
+     - Do NOT add validation rules that aren't in validation-changes.md
+  
+  2. **Be Precise**: Update only the specific items that changed
+     - Field added? Add one row to table
+     - Field removed? Remove one row from table
+     - Validation rule added? Add one bullet point
+     - That's it - nothing more
+  
+  3. **Preserve Everything Else**: Keep existing content exactly as-is
+     - Same section hierarchy and formatting
+     - Same wording for unchanged items
+     - Same examples and notes
+  
+  4. **Match Style**: Use the same voice, tone, and formatting as existing content
+  
+  5. **Be Complete**: Ensure all changes from validation-changes.md are reflected
+  
+  6. **Document Changes**: Create a thorough update-summary.md for review
+  
+  7. **Verify**: Double-check that your updates accurately reflect the validation changes
+  
+  ## File Locations Summary
+  
+  - Input 1: `./validation-changes.md` (change documentation)
+  - Input 2: `${RECIPE_REF_PATH}` or `${GOOSE_REPO}/documentation/docs/guides/recipes/recipe-reference.md` (target file)
+  - Output 1: Same as Input 2 (updated in place)
+  - Output 2: `./update-summary.md` (change summary)
+  
+  ## Environment Variables
+  
+  - `RECIPE_REF_PATH`: Full path to recipe-reference.md file (overrides default)
+  - `GOOSE_REPO`: Path to goose repository (used if RECIPE_REF_PATH not set)
+  
+  The recipe will check for these environment variables and construct the path accordingly.
+  
+  Start by reading both input files, then apply the updates and generate the summary.
+
+prompt: |
+  Please update the Recipe Reference Guide based on the validation changes in validation-changes.md.
+  
+  CRITICAL INSTRUCTIONS:
+  1. Only make changes that are explicitly documented in validation-changes.md
+  2. Do NOT make general improvements, reorganizations, or clarifications
+  3. Use the EXACT file path from the RECIPE_REF_PATH environment variable when editing recipe-reference.md
+     - Do NOT create shortened paths or use ~ notation
+     - The full path is provided in the RECIPE_REF_PATH environment variable
+  
+  Update THREE areas:
+  1. Core Recipe Schema table - for field additions/removals/type changes
+  2. Field Specifications sections - add/remove sections for complex fields (follow existing patterns)
+  3. Validation Rules section - for validation function changes
+  
+  For each change in validation-changes.md:
+  - Field added? Add row to schema table + Field Specification section if complex
+  - Field removed? Remove row from schema table + Field Specification section if exists
+  - Field type changed? Update type/required columns + update Field Specification if exists
+  - Enum value added? Update enum lists in Field Specifications (e.g., Input Types)
+  - Validation rule added? Add bullet point with function name
+  - Validation rule removed? Remove bullet point
+  
+  When adding Field Specification sections:
+  - Look at similar existing sections (e.g., Activities, Parameters, Settings)
+  - Match their structure: schema table, description, examples, usage notes
+  - Keep the same style and formatting
+  - Use information from validation-changes.md
+  
+  Do NOT:
+  - Rewrite existing descriptions
+  - Add validation rules not in validation-changes.md
+  - Reorganize sections
+  - Make "improvements" to existing content
+  - Add character limits unless they're new in validation-changes.md
+  
+  Generate update-summary.md documenting exactly what you changed.
