Claude Code Project

Claude Code Project Manager

Manage and maintain Claude Code project configuration files. This skill provides three invokable workflows for keeping your Claude Code setup optimized and in sync with your project.

When to Use Each Command

Prerequisites

Before running any command, understand the current project state:

1. Check if .claude/ directory or CLAUDE.md exists in the project root
2. Check if AGENTS.md exists (may be imported by CLAUDE.md)
3. Identify the project stack (language, framework, build tools) by examining:
   • package.json, Cargo.toml, pyproject.toml, go.mod, etc.
   • Dockerfile, docker-compose.yml, Makefile, justfile
   • CI/CD configs (.github/workflows/, .gitlab-ci.yml)
   • Test runner configs (vitest.config.*, jest.config.*, pytest.ini)
4. Run ls -la .claude/ or check for .claude/ directory structure

/update-project: Update CLAUDE.md and AGENTS.md

Review the current project state and update documentation to reflect reality.

Workflow

1. Read existing files: Read current CLAUDE.md, AGENTS.md, and .claude/ contents
2. Analyze project: Detect the actual stack, tools, commands, and conventions currently in use
3. Identify gaps: Compare actual state vs documented state using the checklist in references/update-project-checklist.md
4. Update CLAUDE.md: Rewrite or patch to reflect current reality. Follow the template in assets/claude-md-template.md
5. Update AGENTS.md: If used, ensure it imports correctly and covers agent conventions
6. Summarize changes: Report what changed and why

CLAUDE.md Best Practices (from code.claude.com/docs)

• Be comprehensive but concise. Every line should earn its place — prefer specific rules over vague ones, but do not omit important conventions just to stay short
• Target under 200 lines as a guideline. If you need more, use .claude/rules/ for path-scoped instructions and @imports for detailed guides
• Load every session — only include broadly-applicable rules
• List all commands: build, test, lint, format, dev, db commands Claude should know
• Be specific: "Use 2-space indentation" not "Format code properly"
• Use @imports: Pull in README, package.json with @README, @package.json
• Keep personal prefs in CLAUDE.local.md (gitignored, not committed)
• Use .claude/rules/ for path-scoped instructions that load only when needed
• Place at project root or .claude/CLAUDE.md — both work

CLAUDE.md Required Sections

A high-quality CLAUDE.md should cover these categories. Adapt to the project's stack:

Commands (always include):

• Dev server, build, start (production)
• Test (once + watch mode if available)
• Lint, format (write + check modes)
• Type check
• Database commands (generate, migrate, seed, studio)
• Any other frequently-used scripts

Stack (always include):

• Language + version + strict mode status
• Framework + version + key features (e.g., App Router)
• Database / ORM
• Key libraries (validation, styling, testing)
• Build tool / bundler

Code Style:

• Indentation (spaces/tabs, count)
• Naming conventions (files, components, functions, variables)
• Import/export style (ES modules vs CommonJS, named vs default)

Rules (specific and verifiable):

• File organization (directory structure, test colocation)
• Component patterns (Server Components vs Client Components)
• API conventions (request/response shapes, error handling)
• Validation rules (input validation library, schemas)
• Git workflow (branch naming, commit style, pre-commit checks)
• Security rules (secrets handling, auth patterns)

Testing:

• Test runner and location
• Mocking policy (what to mock, what not to mock)
• Coverage expectations

AGENTS.md Notes

• Claude Code reads CLAUDE.md, not AGENTS.md directly
• If AGENTS.md exists for other agents, import it from CLAUDE.md: @AGENTS.md
• Add Claude-specific instructions after the import
• AGENTS.md is optional — only create if other tools need it too

What to Check

Read references/update-project-checklist.md for the full checklist.

/verify-project: End-to-End Verification

Run a comprehensive audit of the entire Claude Code project setup.

Workflow

1. Read all config files: .claude/, CLAUDE.md, AGENTS.md, .mcp.json, settings.json, settings.local.json
2. Check file structure: Validate directory layout follows conventions
3. Validate syntax: Ensure all markdown frontmatter, JSON, and configs parse correctly
4. Check cross-references: Verify imports (@file) point to existing files
5. Verify hooks: Check hook scripts are executable and reference valid commands
6. Test MCP connectivity: Verify .mcp.json servers are accessible if possible
7. Check skills: Verify .claude/skills/*/SKILL.md files have valid frontmatter
8. Check subagents: Verify .claude/agents/*.md files have valid frontmatter
9. Validate rules: Ensure .claude/rules/*.md have proper globs and content
10. Report findings: Output pass/fail for each check with specific issues

Read references/verify-project-checklist.md for the full checklist.

Common Issues to Flag

• CLAUDE.md > 200 lines without path-scoped rules
• Missing build/test/format commands in CLAUDE.md
• @import references to non-existent files
• Subagents with duplicate name fields
• Hooks referencing commands not in PATH
• skills without YAML frontmatter or missing name/description
• AGENTS.md not imported in CLAUDE.md (if both exist)

/check: Discover Improvements

Audit the project setup and suggest improvements for tools, MCPs, skills, hooks, and configuration.

Workflow

1. Analyze the project: Read package.json, README, Dockerfile, CI configs, source structure
2. Check current .claude/ setup: List all existing configuration
3. Identify gaps: Compare against the improvement categories in references/check-improvements-guide.md
4. Search for skills: If skill recommendations needed, use the npx skills CLI (see Skill Discovery below)
5. Propose improvements: Deliver prioritized, actionable recommendations

Improvement Categories

1. CLAUDE.md quality: Length, specificity, command coverage, import usage
2. Missing tools: Build, test, lint, format tools not documented
3. MCP opportunities: External services (databases, APIs, cloud) that could benefit from MCP
4. Skill gaps: Workflows that could be automated with skills
5. Subagent opportunities: Tasks that would benefit from specialized subagents
6. Hook opportunities: Automated actions (format-on-save, lint checks, notifications)
7. Rules organization: Path-scoped rules for monorepos or multi-language projects
8. Settings optimization: Permission modes, model selection, context management

Skill Discovery with npx skills CLI

Use the Skills CLI for all skill operations. Do NOT browse the website — use the terminal.

Key commands:

# Search for skills by keyword
npx skills find <keyword>
# Example: npx skills find react
# Example: npx skills find testing

# Interactive search (opens fzf-style picker, no arguments)
npx skills find

# List currently installed skills (project + global)
npx skills list

# List only globally installed skills
npx skills ls -g

# Check for skill updates
npx skills check

# Update all installed skills
npx skills update

# Install a skill
npx skills add <owner/repo>
# Example: npx skills add vercel-labs/agent-skills

# Install a specific skill from a multi-skill repo
npx skills add <owner/repo> --skill <skill-name>

# Remove a skill
npx skills remove <skill-name>

# Create a new skill scaffold
npx skills init <skill-name>

How to recommend skills in /check:

1. Run npx skills list to see what the user already has installed
2. Identify gaps based on the project stack (e.g., React project missing React skills)
3. Run npx skills find <keyword> to search for relevant skills (e.g., npx skills find react)
4. Verify quality: prefer 1K+ installs, official sources (anthropics, vercel-labs, microsoft)
5. Report: skill name, purpose, install command, why it fits

Common skills by category (use npx skills find <keyword> to discover):

• React/Next.js: Search npx skills find react or npx skills find nextjs
• Testing: Search npx skills find testing or npx skills find tdd
• Design: Search npx skills find design or npx skills find frontend
• Code review: Search npx skills find review
• Architecture: Search npx skills find architecture
• Security: Search npx skills find security

Managing Installed Skills

When the user needs to manage existing skills (list, update, remove):

# See all installed skills
npx skills list

# Check which skills have updates available
npx skills check

# Update everything
npx skills update

# Remove a skill no longer needed
npx skills remove <skill-name>

# Install skill globally (available in all projects)
npx skills add <owner/repo> -g

# Install skill to project only (committed to repo)
npx skills add <owner/repo>
