Troubleshoot extensions, hooks, and unexpected behavior.
# Enable debug mode
claude --debug
# Check loaded extensions
/hooks # View registered hooks
/agents # View available agents
/memory # View loaded memory files
/config # View current configuration
| Symptom | Quick Check |
|---|---|
| Skill not activating | Verify description has trigger keywords |
| Hook not running | Check chmod +x, run /hooks |
| Agent not delegating | Add "Use proactively" to description |
| MCP connection fails | Test server manually with npx |
| Permission denied | Check settings.json allow rules |
claude --debug
# Shows:
# - Hook execution and errors
# - Skill loading status
# - Subagent invocations
# - Tool permission decisions
# - MCP server connections
# Check structure
ls -la .claude/skills/my-skill/
# Must have: SKILL.md
# Verify YAML frontmatter
head -10 .claude/skills/my-skill/SKILL.md
# Must start/end with ---
# Check name matches directory
grep "^name:" .claude/skills/my-skill/SKILL.md
# Make executable
chmod +x .claude/hooks/my-hook.sh
# Test manually
echo '{"tool_name":"Bash"}' | .claude/hooks/my-hook.sh
echo $? # Check exit code
# Verify JSON syntax
jq '.' ~/.claude/settings.json
# Check file location
ls ~/.claude/agents/
ls .claude/agents/
# Verify description includes "Use for:" or "Use proactively"
grep -i "use" agents/my-agent.md | head -5
# Explicitly request
# "Use the my-agent agent to analyze this"
# Run all validations
just test
# YAML validation only
just validate-yaml
# Name matching only
just validate-names

Use this skill when the user explicitly asks to map, document, or onboard into an existing codebase. Trigger for prompts like "map this codebase", "document this architecture", "onboard me to this repo", or "create codebase docs". Do not trigger for routine feature implementation, bug fixes, or narrow code edits unless the user asks for repository-level discovery.

Patterns and techniques for adding governance, safety, and trust controls to AI agent systems. Use this skill when: - Building AI agents that call external tools (APIs, databases, file systems) - Implementing policy-based access controls for agent tool usage - Adding semantic intent classification to detect dangerous prompts - Creating trust scoring systems for multi-agent workflows - Building audit trails for agent actions and decisions - Enforcing rate limits, content filters, or tool restrictions on agents - Working with any agent framework (PydanticAI, CrewAI, OpenAI Agents, LangChain, AutoGen)
