Test PR: Claude Code Review Skill Tool Investigation

This PR tests whether Claude Code Review (GitHub Actions) has access to the Skill tool.


@claude Please answer the following questions to help us understand your capabilities:

  1. What tools do you have available? Please list ALL tools you can use.
  2. Do you have a Skill tool? Can you invoke skills?
  3. Can you see skills defined in .claude/skills/ or .cursor/skills/? List any skills you're aware of.
  4. Try running /write-docs - does that work as a skill invocation?
  5. What does your loaded context tell you about available skills?
  6. Try using the Skill tool directly: Skill(write-docs) - what happens?

This will help us determine if we need to manually inject skill content into review prompts or if skills work automatically.


This is a test PR and will be closed after the investigation.

Adds a new system to generate curated documentation collections ("skills")
that can be consumed by AI agents and LLMs. Collections are published to
a separate repo (inkeep/skills) via GitHub Action.

Key features:
- Tag docs with `skillCollections` frontmatter to include in collections
- Template system for customizing collection index files
- Auto-publishes to inkeep/skills on push to main
- Snippets are expanded inline for complete, standalone content

Also improves LLM text generation by switching from custom MDX stripping
to Fumadocs native `getText('processed')` for higher fidelity output that
preserves MDX components like <Tip>, <Tabs>, etc.

New files:
- .github/workflows/publish-skills.yml - GitHub Action for publishing
- agents-docs/scripts/generate-skill-collections.ts - Generator script
- agents-docs/skills-collections/ - Templates and documentation
- Move skill templates to _templates/skills/ folder
- Delete default.mdx - every skill must have an explicit template
- Change COLLECTIONS_LIST to render as table with name/description
- Remove 'collections' terminology from generated README
Rules are now generated directly in rules/*.md instead of rules/path/to/*.md
…ructure, and rule frontmatter

- Handle filename conflicts by prefixing with parent folder names
- Change template structure to _templates/skills/<name>/SKILL.mdx
- Add frontmatter to rule files with title, description, topic-path
- Update documentation with new structure and features
- Add skillCollections to meta.json for folder-level inheritance
- Respect pages array ordering from meta.json
- Support "..." wildcard for remaining files
- Child folders inherit from parents unless overridden
- File frontmatter can override inherited collections
- Remove redundant skillCollections from individual MDX files
- Update documentation with new meta.json approach
- Add SkillRule MDX component for embedding procedural content in docs
- Support MDX serialization (JSX elements preserved as raw text)
- Implement exclusive logic: file-level skills OR SkillRule extraction
- Rename skillCollections to skills across config and frontmatter
- Update README with best practices for skill inclusion methods
- Add mdast-util-mdx for JSX serialization support

Claude Code Review Capability Investigation

I've completed my systematic investigation of tool access and capabilities. Here are the comprehensive answers to your questions:

Todo List:

  • List all available tools I can access
  • Check if I have a Skill tool specifically
  • Examine skills in .claude/skills/ and .cursor/skills/ directories
  • Test /write-docs skill invocation
  • Analyze loaded context for skill information
  • Test direct Skill tool invocation
  • Provide comprehensive summary of findings

Comprehensive Findings

1. What tools do you have available?

I have access to these 18 tools:

  • Task - Launch specialized agents for complex tasks (general-purpose, statusline-setup, output-style-setup, git-rebase-coordinator)
  • Bash - Execute shell commands with persistent session
  • Glob - Fast file pattern matching with glob patterns
  • Grep - Powerful search tool built on ripgrep
  • LS - List files and directories
  • ExitPlanMode - Exit plan mode for implementation planning
  • Read - Read files from filesystem (supports images, PDFs, Jupyter notebooks)
  • Edit/MultiEdit - Edit files with find-and-replace operations
  • Write - Write new files to filesystem
  • NotebookEdit - Edit Jupyter notebook cells specifically
  • TodoWrite - Create and manage structured task lists
  • BashOutput/KillBash - Monitor/kill background bash processes
  • mcp__github_comment__update_claude_comment - Update GitHub comments (this tool)

2. Do you have a Skill tool?

No. I do not have access to a dedicated Skill tool. None of my available tools provide skill invocation capabilities.

3. Can you see skills defined in .claude/skills/ or .cursor/skills/?

Yes. I can read the skill files and found:

  • .claude/skills/ is a symlink to .cursor/skills/
  • .cursor/skills/ contains 6 skills:
    • write-docs - Documentation writing with MDX patterns, frontmatter, and content structure
    • prd - Product Requirements Document generation with user stories and acceptance criteria
    • ralph - PRD to JSON conversion for autonomous agent execution
    • data-model-changes - Database/model change guidance
    • web-design-guidelines - Web design patterns and guidelines
    • react/ and vercel-react-best-practices/ - React development rules and performance optimizations

4. Try running /write-docs - does that work?

No. The /write-docs command doesn't exist as an executable:

  • It's not in the system PATH
  • It's not a shell command
  • Bash gives "command not found" when attempted
  • The skill system appears to be file-based documentation, not executable commands

5. What does your loaded context tell you about available skills?

My loaded context includes the complete write-docs skill content as context (from the CLAUDE.md file). This suggests that:

  • Skills are manually injected into my context rather than being callable tools
  • The write-docs skill content was embedded in my system prompt, providing 1,187 lines of documentation guidance
  • This is why I understand documentation patterns, MDX components, and content structure without needing to invoke a tool

6. Try using the Skill tool directly

Cannot test - No Skill tool exists in my available tool set.


Summary and Implications

Current Skill System:

  • ✅ Skills exist as structured markdown files in .cursor/skills/
  • ✅ Skill content can be manually injected into context (as done with write-docs)
  • ❌ No automatic skill discovery or invocation
  • ❌ No dedicated Skill tool for dynamic access
  • ❌ Skills are not executable commands

For Claude Code Review workflows, you need to:

  1. Manual injection: Continue injecting relevant skill content into prompts (current approach)
  2. No Skill tool needed: The --allowedTools doesn't need a Skill tool because it doesn't exist
  3. Context-based approach: Skills work by having their content loaded as context, not by tool invocation

The skills are well-structured and contain valuable guidance (especially write-docs with comprehensive documentation patterns), but they operate as reference material rather than executable tools.

@claude Let's test your subagent/Task tool capabilities:

Subagent Tool Test

  1. Do you have a Task tool? List all tools that mention "Task", "subagent", or "agent".

  2. Try spawning an Explore subagent:

    • Use the Task tool with subagent_type: Explore to search for files matching *.md in this repo
    • Report what happens
  3. Can you see custom subagents?

    • Check if you can see .claude/agents/git-rebase-coordinator.md
    • Can you use it?
  4. Try parallel subagents:

    • Can you spawn multiple Task agents in parallel?
  5. What agent types are available to you? List them all (e.g., Explore, Plan, general-purpose, Bash, etc.)

This helps us understand if Claude Code Review can delegate to subagents like the local CLI does.

Subagent/Task Tool Capability Test

I'll systematically test my subagent and Task tool capabilities to help understand what Claude Code Review can do.

Todo List:

  • List all Task/subagent/agent-related tools
  • Test spawning an Explore subagent for *.md file search
  • Check for custom subagents in .claude/agents/
  • Test parallel Task agent execution
  • List all available agent types
  • Provide comprehensive summary

Test Results

1. Do you have a Task tool?

Yes! I have access to these Task/subagent related tools:

  • Task - Launch a new agent to handle complex, multi-step tasks autonomously

    • Parameters: subagent_type, description, prompt, model, run_in_background, resume, allowed_tools, max_turns
    • Can spawn specialized agents with specific capabilities
    • Supports parallel execution, background tasks, and session resumption
  • TaskOutput - Retrieves output from running or completed tasks

    • Parameters: task_id, block, timeout
    • Works with background shells, async agents, and remote sessions
  • TaskStop - Stops a running background task by its ID

2. Try spawning an Explore subagent

Success! The Explore subagent worked perfectly:

  • Successfully spawned with subagent_type: Explore
  • Found all 162 markdown files in the repository
  • Returned comprehensive file listing organized by directory
  • Provided agent ID a6261a5 for potential session resumption

3. Can you see custom subagents?

Yes! I found and can read custom subagents:

Found in .claude/agents/git-rebase-coordinator.md:

  • Name: git-rebase-coordinator
  • Purpose: Complex rebase operations with conflict resolution
  • Model: sonnet
  • Contains detailed workflow instructions for rebasing branches

The file exists and contains comprehensive agent instructions for handling git rebase operations. Based on my Task tool description, this agent should be available as subagent_type: git-rebase-coordinator.

4. Try parallel subagents

Success! Parallel execution works:

  • Spawned two general-purpose agents simultaneously
  • Both executed in parallel and returned results:
    • Agent 1 (ID: a72b550): Found 1,557 TypeScript (.ts) files
    • Agent 2 (ID: a49687d): Found 430 TypeScript React (.tsx) files
  • Both completed successfully with detailed breakdowns

5. What agent types are available to you?

Based on my Task tool documentation, I have access to these agent types:

Core Agent Types:

  1. Bash - Command execution specialist for running bash commands, git operations
  2. general-purpose - General agent for researching questions, searching code, multi-step tasks
  3. statusline-setup - Configure Claude Code status line settings
  4. Explore - Fast codebase exploration specialist (search by patterns, keywords)
  5. Plan - Software architect agent for implementation planning
  6. claude-code-guide - Help with Claude Code, Agent SDK, and API questions
  7. git-rebase-coordinator - Rebase management with conflict resolution

Agent Capabilities by Type:

  • Bash: Has access to Bash tool only
  • general-purpose: Has access to all tools (*)
  • statusline-setup: Read, Edit tools
  • Explore: All tools except Task, ExitPlanMode, Edit, Write, NotebookEdit
  • Plan: All tools except Task, ExitPlanMode, Edit, Write, NotebookEdit
  • claude-code-guide: Glob, Grep, Read, WebFetch, WebSearch
  • git-rebase-coordinator: All tools

Summary & Implications

✅ Claude Code Review HAS full subagent capabilities:

  1. Task tool is available - Can spawn and manage subagents
  2. All agent types work - Successfully tested Explore and general-purpose agents
  3. Parallel execution works - Can run multiple agents simultaneously for efficiency
  4. Custom agents accessible - Can see and likely use custom agents like git-rebase-coordinator
  5. Background execution supported - Can run tasks in background with run_in_background parameter
  6. Session resumption - Each agent returns an ID for potential resumption

Key Differences from Skill Tool Test:

  • ✅ Task/subagent system: Fully functional
  • ❌ Skill system: Not available as a tool (skills must be manually injected)

This means Claude Code Review can effectively delegate complex tasks to specialized subagents, making it capable of handling sophisticated multi-step operations, parallel processing, and specialized workflows like git rebasing.

@claude Let's test if your subagents have access to the Skill tool (even though you don't):

Nested Skill Tool Test

  1. Spawn a general-purpose subagent and ask it to:

    • List ALL its available tools
    • Specifically check if it has a Skill tool
    • Try to invoke /write-docs or Skill(write-docs)
  2. Spawn an Explore subagent and ask it to:

    • List its available tools
    • Check for Skill tool access
  3. Try spawning a subagent with explicit skill access:

    • Use allowed_tools: ["Skill", "Skill(*)"] parameter if possible
    • See if that grants skill access
  4. Check if subagents can see .claude/skills/:

    • Have a subagent read and report on skill files
    • Can it understand/apply skill content even without the Skill tool?

This tests whether the Skill tool might be available at a different level in the agent hierarchy.

Testing Nested Subagent Skill Tool Access

Test Results:

  • Test 1: Spawn general-purpose subagent to check for Skill tool
  • Test 2: Spawn Explore subagent to check for Skill tool
  • Test 3: Try spawning with explicit allowed_tools: ["Skill"]
  • Test 4: Have subagents read and apply skill content from .claude/skills/

🔍 Key Discovery: Subagents DO Have the Skill Tool!

Test 1: General-Purpose Subagent ✅

HAS the Skill tool - Successfully invoked write-docs and can access all skills

Test 2: Explore Subagent ✅

HAS the Skill tool - Full access to Skill tool and all available skills

Test 3: Explicit Skill Access ⚠️

  • Attempting allowed_tools: ["Skill"] triggers a permission request
  • The system recognizes "Skill" as a valid tool but requires approval
  • This confirms Skill is a real tool in the system

Test 4: Direct Skill File Access ✅

Subagents can:

  • Read all skill files in .claude/skills/ (symlink to .cursor/skills/)
  • Found 7 skills: write-docs, prd, ralph, data-model-changes, react, vercel-react-best-practices, web-design-guidelines
  • Apply skill knowledge manually without the Skill tool
  • Understand the dual-access model (Skill tool vs direct reading)

📊 Summary

Critical Finding: Tool access differs by agent level!

Agent Type Has Skill Tool? Can Spawn Subagents?
Claude Code Review (me) ❌ No ✅ Yes (via Task)
General-Purpose Subagent ✅ Yes ✅ Yes
Explore Subagent ✅ Yes ❌ No (Task excluded)

Implications:

  1. Subagents are more powerful - They have tools that parent agents don't
  2. Skill tool exists - It's a real tool, just not available at the review level
  3. Workaround available - Claude Code Review can spawn subagents to access skills
  4. Manual fallback - Skills can be read and applied manually via Read tool

Architecture insight: The system appears designed with different tool access levels:

  • Review agents: Focus on code review with limited tools
  • Subagents: Full tool access including Skills for comprehensive work
  • This separation likely provides security and scope control

Recommendation for Claude Code Review workflows:

  • Continue manual skill injection for direct review tasks
  • When skill access is needed, spawn a subagent with appropriate type
  • Use general-purpose subagents when Skill tool access is required

@claude Let's test if CLAUDE.md is automatically loaded at different agent levels:

CLAUDE.md Auto-Loading Test

  1. Check YOUR (parent agent) loaded context:

    • Do you have knowledge from CLAUDE.md/AGENTS.md without reading it?
    • What do you know about: pnpm bump, pnpm db:generate, the project's testing patterns?
    • Can you recite any specific rules from CLAUDE.md?
  2. Spawn a general-purpose subagent and ask it:

    • "What project-specific instructions do you have loaded?"
    • "Do you know what pnpm bump does in this repo?"
    • "What testing framework does this project use?"
  3. Spawn an Explore subagent and ask the same questions

  4. Compare: Which agents have CLAUDE.md context pre-loaded vs need to read it?

This tests if the CLAUDE.md memory system works in GitHub Actions context.

CLAUDE.md Auto-Loading Test ✅

Todo List:

  • Check my (parent agent) loaded context from CLAUDE.md
  • Test general-purpose subagent's pre-loaded knowledge
  • Test Explore subagent's pre-loaded knowledge
  • Compare which agents have CLAUDE.md pre-loaded
  • Provide comprehensive summary

🎯 Key Discovery: ALL Agents Have CLAUDE.md Pre-loaded!

Agent Type Has CLAUDE.md Pre-loaded? Knowledge Level
Claude Code Review (me) ✅ Yes Full CLAUDE.md/AGENTS.md content
General-Purpose Subagent ✅ Yes Full CLAUDE.md/AGENTS.md content
Explore Subagent ✅ Yes Full CLAUDE.md/AGENTS.md content

📊 Detailed Findings

All three agent levels demonstrated identical knowledge of:

  1. pnpm bump command - All knew the exact syntax, valid packages, and semver guidelines
  2. Database migration workflow - All knew pnpm db:generate, the 4-step process, and critical rules
  3. Testing patterns - All knew Vitest, 60-second timeouts, __tests__ directories, pglite database
  4. Specific CLAUDE.md rules - All could recite rules about pnpm, mandatory requirements, file editing preferences

🔍 Evidence of Pre-loading

Parent Agent (me):

  • ✅ Could recite exact commands and rules without reading files
  • ✅ Knew specific quotes like "Only use emojis if the user explicitly requests it"
  • ✅ Had full workflow knowledge (database, testing, changesets)

General-Purpose Subagent:

  • ✅ Provided detailed pnpm bump syntax with examples
  • ✅ Listed all valid package names correctly
  • ✅ Knew the mandatory 3-component requirement for new features

Explore Subagent:

  • ✅ Demonstrated same depth of knowledge
  • ✅ Could cite specific rules about drizzle/meta/ and migration handling
  • ✅ Knew exact testing patterns and import statements

💡 Implications

  1. CLAUDE.md memory system works perfectly in GitHub Actions - The context is reliably pre-loaded at all agent levels

  2. No manual injection needed - Unlike skills (which require manual injection or Skill tool), CLAUDE.md is automatically available

  3. Consistent behavior across agent hierarchy - Whether parent or subagent, all have the same project-specific knowledge

  4. Architecture insight: The system appears to inject CLAUDE.md/AGENTS.md into the system prompt for ALL agent types, ensuring consistent project knowledge across the entire agent hierarchy

This confirms that the CLAUDE.md system is working as designed in the GitHub Actions environment, providing all agents with essential project context without requiring explicit file reading or tool usage.

Testing PR Review Documentation Updates Subagent

Todo List:

  • Update comment with initial task list
  • Attempt to spawn the pr-review-docs-updates subagent
  • Check for agent definition files
  • Use alternative approach with general-purpose agent
  • Report comprehensive findings

Test Results

1. ❌ Subagent Loading

The pr-review-docs-updates subagent does not exist in the system. When attempting to spawn it, I received:

Agent type 'pr-review-docs-updates' not found. Available agents: Bash, general-purpose, statusline-setup, Explore, Plan, claude-code-guide, git-rebase-coordinator

2. ✅ Alternative Testing with General-Purpose Agent

Successfully used a general-purpose subagent to test documentation review capabilities:

  • Subagent loaded successfully: Yes
  • Able to invoke write-docs skill: Yes (via Skill tool)
  • Applied skill guidelines: Yes

3. ✅ Output Format Assessment

The general-purpose subagent produced a comprehensive structured report including:

  • Overall assessment with letter grade
  • Documentation quality checks (strengths & critical issues)
  • Formatting and structure review
  • Content accuracy and completeness analysis
  • Detailed improvement suggestions
  • Proper MDX code examples

4. Issues Identified

Missing Subagent Definition

  • No pr-review-docs-updates agent type exists in the system
  • No files matching **/*pr-review* pattern found
  • Only custom agent found: git-rebase-coordinator in .claude/agents/

Potential Solutions

  1. Create the missing subagent: Add pr-review-docs-updates.md to .claude/agents/ directory
  2. Use existing agents: The general-purpose agent works well for documentation reviews when instructed to use the write-docs skill
  3. Update agent registry: The subagent may need to be registered in the Task tool's available agent types

5. Key Finding

While the specialized pr-review-docs-updates subagent doesn't exist, the general-purpose subagent with the write-docs skill works perfectly for documentation reviews. It:

  • Successfully invoked the skill
  • Applied all documentation guidelines
  • Produced a thorough, structured review
  • Identified missing frontmatter, incorrect file location, and formatting issues
  • Provided actionable improvement suggestions with code examples

Summary: The pr-review-docs-updates subagent needs to be created and registered before it can be used. However, the general-purpose agent with skill invocation provides equivalent functionality for documentation reviews.

Testing Custom Subagent Discovery ✅

Todo List:

  • Check available agent types for pr-review-docs-updates
  • Spawn the pr-review-docs-updates subagent to review docs
  • Report the full structured output from the subagent
  • Provide comprehensive findings

🎉 Success! Custom Subagent is Available

Key Discovery

The pr-review-docs-updates subagent is now available and works perfectly!

When I attempted to spawn it with subagent_type: pr-review-docs-updates, it:

  1. Loaded successfully from .claude/agents/pr-review-docs-updates.md
  2. Executed its specialized documentation review logic
  3. Produced a comprehensive structured report
  4. Applied the write-docs skill guidelines correctly

Full Structured Output from the Subagent

The subagent produced a professional documentation review report with:

Report Structure:

  • Files Reviewed: 2 files analyzed
  • Total Issues Found: 5 issues categorized by severity
  • Critical Issues: None found
  • Warnings: 2 issues (backticks in prose, slash command clarity)
  • Suggestions: 3 improvements (readability, phrasing, meta commentary)
  • Compliance Summary: Table checking frontmatter, structure, components, code examples, and links

Quality Indicators:

  • ✅ Applied write-docs skill standards correctly
  • ✅ Used structured markdown tables for findings
  • ✅ Provided line numbers and specific recommendations
  • ✅ Categorized issues by severity (Critical/Warning/Suggestion)
  • ✅ Included positive observations and constructive feedback

Technical Insights

How Custom Subagents Work:

  1. Definition Location: .claude/agents/*.md files define custom subagents
  2. Discovery: Subagents are discovered when they're part of the PR/repository
  3. Invocation: Use exact filename (without .md) as subagent_type
  4. Execution: The Task tool loads the agent definition and executes according to instructions

Important Finding:
The system dynamically discovers custom subagents from .claude/agents/ when they're present in the repository. This means:

  • ✅ Custom subagents defined in PRs are immediately available
  • ✅ No registration or compilation step needed
  • ✅ Agent definitions are hot-loaded from the filesystem

Summary

This test confirms that custom subagents in .claude/agents/ are automatically discovered and available when they're part of the PR. The pr-review-docs-updates subagent:

  1. Was successfully discovered from the filesystem
  2. Loaded and executed correctly
  3. Performed its specialized documentation review as designed
  4. Produced high-quality structured output following its defined format

This validates that the custom subagent system works as intended in GitHub Actions context, allowing teams to define specialized review agents that are immediately available in their PRs.
