Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, keyword triggers, hook mechanisms (UserPromptSubmit), session tracking, and the 500-line rule.\n---\n\n# Skill Developer Guide\n\n## Purpose\n\nComprehensive guide for creating and managing skills in Claude Code with auto-activation system, following Anthropic's official best practices including the 500-line rule and progressive disclosure pattern.\n\n## Domain Skill for Skill System\n\nThis is a domain skill for the skills system itself. It's automatically loaded when you work with skills.\n\n**This skill covers:**\n\n- The 500-line rule (max 5 files > 500 lines, none > 600 lines)\n- TOC and line number prohibition (never add these to skills)\n- When skills need updates (new dirs, patterns, docs, triggers)\n- Self-healing mechanisms (pre-commit hook, /wrap checklist)\n- Progressive disclosure patterns (main file → resource files)\n\n**Use this skill explicitly when:**\n\n- Creating or modifying any skill\n- Debugging skill activation issues\n- Understanding the skills system architecture\n\n## When to Use This Skill\n\nAutomatically activates when you mention:\n\n- Creating or adding skills\n- Modifying skill triggers or rules\n- Understanding how skill activation works\n- Debugging skill activation issues\n- Working with skill-rules.json\n- Hook system mechanics\n- Claude Code best practices\n- Progressive disclosure\n- YAML frontmatter\n- 500-line rule\n\n## Related Skills\n\nThis skill helps create and manage all other skills. When building skills, reference:\n\n- **testing-strategy** - Skills should be tested with real scenarios before extensive documentation\n\n## Relationship to CLAUDE.md\n\n**Division of Responsibilities:**\n\n- **CLAUDE.md**: Global project context, high-level architecture, universal style rules\n- **Skills**: Domain-specific detailed guidance, patterns, procedures (triggered by context)\n- **skill-developer**: Domain skill that guides the skills system and explains its relationship to CLAUDE.md\n\n**When to Update:**\n\n- Global style rules (numpy docstrings, no emojis, use venv) → Update CLAUDE.md\n- Domain patterns/practices (test patterns, architecture design) → Update relevant skill\n- Skill system mechanics (triggers, hooks, 500-line rule) → Update skill-developer\n\n**Integration:**\n\n- CLAUDE.md references skills for detailed guidance (1-line pointers)\n- Skills don't reference CLAUDE.md (avoid circular dependencies)\n- skill-developer explains the complete hierarchy (this section)\n\n**Progressive Disclosure Hierarchy:**\n\n```\nCLAUDE.md (Global Context)\n    ↓ references\nSkills (Domain Guidance)\n    ↓ maintained by\nskill-developer (Domain Skill)\n```\n\n______________________________________________________________________\n\n## System Overview\n\nThe skills system uses **automatic injection** to seamlessly provide domain-specific context when you need it.\n\n**Key concepts:**\n\n- **Domain skills** (e.g., python-best-practices, skill-developer): Automatically injected when detected based on prompt keywords and AI intent analysis (autoInject: true)\n- **Guardrail skills** (e.g., api-security): Enforce critical best practices, automatically injected when detected\n- **Automatic detection & injection**: Skills detected via AI-powered intent analysis and immediately loaded into context - no manual intervention needed\n\n**For complete details**, see [two-tier-system.md](resources/two-tier-system.md):\n\n- Skill detection mechanism\n- Automatic skill detection and injection\n- Hook architecture and flow\n- Workflow examples and scenarios\n- Session state management\n\n______________________________________________________________________\n\n## Skill Types\n\n### 1. Guardrail Skills\n\n**Purpose:** Enforce critical best practices that prevent errors\n\n**Characteristics:**\n\n- Type: `\"guardrail\"`\n- Automatically injected when detected (autoInject: true)\n- Prevent common mistakes (column names, critical errors)\n- Session-aware (only inject once per conversation)\n\n**Examples:**\n\n- `database-verification` - Verify table/column names before Prisma queries\n- `frontend-dev-guidelines` - Enforce React/TypeScript patterns\n\n**When to Use:**\n\n- Mistakes that cause runtime errors\n- Data integrity concerns\n- Critical compatibility issues\n\n### 2. Domain Skills\n\n**Purpose:** Provide comprehensive guidance for specific areas\n\n**Characteristics:**\n\n- Type: `\"domain\"`\n- Advisory, not mandatory\n- Topic or domain-specific\n- Comprehensive documentation\n- Automatically injected when detected (autoInject: true)\n\n**Examples:**\n\n- `backend-dev-guidelines` - Node.js/Express/TypeScript patterns\n- `frontend-dev-guidelines` - React/TypeScript best practices\n- `error-tracking` - Sentry integration guidance\n\n**When to Use:**\n\n- Complex systems requiring deep knowledge\n- Best practices documentation\n- Architectural patterns\n- How-to guides\n\n______________________________________________________________________\n\n## Creating New Skills\n\n**5-step process:**\n\n1. Create SKILL.md with YAML frontmatter\n1. Add to skill-rules.json with triggers\n1. Test detection (UserPromptSubmit hook)\n1. Refine patterns based on results\n1. Keep under 500 lines with progressive disclosure\n\n**For complete step-by-step guide**, see [skill-creation-guide.md](resources/skill-creation-guide.md):\n\n- File templates and naming conventions\n- skill-rules.json configuration\n- Trigger testing commands\n- Pattern refinement strategies\n- Best practices and common mistakes\n\n______________________________________________________________________\n\n## CRITICAL: The 500-Line Rule\n\n**Absolute Limits for ALL Skill Markdown Files:**\n\n- ✅ **Target**: ALL skill files under 500 lines\n- ⚠️ **Warning Zone**: Only **5 files maximum** can breach 500 lines across entire skills system (~50 files)\n- 🚫 **HARD LIMIT**: **NO file should EVER breach 600 lines**\n\n**Why This Matters:**\n\n- Agents process files linearly - long files waste tokens and context\n- 500 lines is the sweet spot for focused, scannable content\n- Progressive disclosure (main file → resource files) is more effective than one giant file\n\n**Enforcement Strategy:**\n\n- If approaching 500 lines → **STOP** and extract content to resource files\n- If already > 500 lines → Refactor immediately unless you can justify it's in the top 5 most important files\n- If approaching 600 lines → **MANDATORY** refactor, no exceptions\n\n**How to Stay Under 500:**\n\n1. Move detailed examples to `resources/` subdirectory\n1. Extract deep-dive content to topic-specific resource files\n1. Use concise summaries in main SKILL.md, point to resources for details\n1. Remove redundancy and wordiness\n\n______________________________________________________________________\n\n## FORBIDDEN: TOCs and Line Number References\n\n**NEVER include in skill markdown files:**\n\n- ❌ **Table of Contents (TOC)** - Bloat for agents, not useful for scanning\n- ❌ **Line number references** (e.g., \"see line 42\") - Change too frequently, create maintenance burden\n- ❌ **Heading navigation links** - Agents can scan headings natively\n\n**Why TOCs Are Harmful:**\n\n- Add 10-50 lines of noise\n- Agents don't benefit from them (they scan headings natively)\n- Become stale when structure changes\n- Waste precious lines toward 500-line limit\n\n**Instead:**\n\n- ✅ Use clear, descriptive section headings\n- ✅ Use anchor text for cross-references (e.g., \"See patterns-library.md\")\n- ✅ Keep files under 500 lines so navigation is unnecessary\n- ✅ Use progressive disclosure (link to resource files for deep dives)\n\n______________________________________________________________________\n\n______________________________________________________________________\n\n## Session State & Deduplication\n\n**Automatic session tracking prevents duplicate injection:**\n\n1. **Session tracking**: Skills are injected once per conversation; subsequent detections reuse already-loaded skills\n1. **State file**: `.claude/hooks/state/{conversation_id}-skills-suggested.json` tracks loaded skills\n1. **Manual loading**: If `autoInject: false` (meta-skills), use `Skill(\"skill-name\")` tool manually\n\n______________________________________________________________________\n\n## Testing & Validation\n\nTest your skills with multiple real-world scenarios before extensive documentation. Verify triggers activate correctly and content provides useful guidance.\n\n______________________________________________________________________\n\n## Reference Files\n\nFor detailed information on specific topics, see:\n\n### [trigger-types.md](resources/trigger-types.md)\n\nComplete guide to keyword triggers:\n\n- Keyword triggers (explicit topic matching)\n- Best practices and examples\n- Common pitfalls and testing strategies\n\n### [skill-rules-reference.md](resources/skill-rules-reference.md)\n\nComplete skill-rules.json schema:\n\n- Full TypeScript interface definitions\n- Field-by-field explanations\n- Complete guardrail skill example\n- Complete domain skill example\n- Validation guide and common errors\n\n### [hook-mechanisms.md](resources/hook-mechanisms.md)\n\nDeep dive into hook internals:\n\n- UserPromptSubmit flow (detailed)\n- Exit code behavior table (CRITICAL)\n- Session state management\n- Performance considerations\n\n### [patterns-library.md](resources/patterns-library.md)\n\nReady-to-use pattern collection:\n\n- Keyword pattern library\n- Organized by use case\n- Copy-paste ready\n\n### [two-tier-system.md](resources/two-tier-system.md)\n\nComplete two-tier architecture guide:\n\n- Meta-skills vs domain skills\n- Automatic skill detection\n- Hook flow and enforcement\n- Workflow examples\n- Session state management\n\n### [skill-creation-guide.md](resources/skill-creation-guide.md)\n\nStep-by-step skill creation:\n\n- File templates and structure\n- skill-rules.json configuration\n- Trigger testing\n- Pattern refinement\n- Best practices and common mistakes\n\n______________________________________________________________________\n\n## Quick Reference\n\n**Create New Skill:**\n\n1. Create SKILL.md with frontmatter → 2. Add to skill-rules.json → 3. Test triggers → 4. Refine → 5. Keep < 500 lines\n\n**Critical Rules:**\n\n- ✅ 500-line limit (max 5 files can breach, none > 600)\n- ✅ Progressive disclosure (use resource files)\n- ✅ NO TOCs or line numbers (forbidden)\n- ✅ Test before documenting (3+ scenarios)\n\n**For Details:** See [trigger-types.md](resources/trigger-types.md), [hook-mechanisms.md](resources/hook-mechanisms.md)\n\n______________________________________________________________________\n\n## Self-Healing & Skill Maintenance\n\n### Automated Skill Health Checks\n\nThe skills system includes automated maintenance to prevent skill drift:\n\n**1. Pre-commit Hook - Skill Reference Validator**\n\n- **Script**: `scripts/pre-commit/validate_skill_references.py`\n- **Runs on**: Changes to skills, internal docs, or src/ files\n- **Validates**:\n  - All file links in SKILL.md point to existing files (prevents broken refs)\n  - New internal docs not yet referenced by skills (suggestions)\n- **Exit behavior**: Fails on broken links, warns on missing references\n\n**2. Manual Checklist - /wrap Command**\n\nWhen wrapping up work, the `/wrap` command includes a skill update checklist:\n\n- New constants/utilities in shared modules → Update code-reuse patterns\n- New docs in project documentation → Update skill resource file links\n- New patterns/features → Update promptTriggers keywords\n\n### Skill Update Workflow\n\n**When code changes:**\n\n1. Pre-commit hook catches broken skill references (automatic)\n1. Pre-commit hook suggests new patterns to add (informational)\n1. `/wrap` command reminds you to check skills (manual)\n1. Review `.claude/skills/` for affected skills\n1. Update skill-rules.json or SKILL.md as needed\n\n**Common updates:**\n\n- **New constants/utilities in shared modules**: Update skill references and patterns\n- **New doc**: Add link to relevant skill's resource","tagline":"Create and manage Claude Code skills following Anthropic best practices.
