Skill Creator — Meta-Skill for Generating Claude Code Skills

A meta-skill that produces new skill packages. It analyzes the target domain, designs the skill structure, and generates all required files following AgenticWorkflow's DNA inheritance patterns.

When to Use

• User asks to create a new skill for a specific domain
• User wants to automate a repeatable workflow as a skill
• System needs to generate skills for thesis workflow agents

Inherited DNA

This meta-skill inherits the AgenticWorkflow genome. As a skill that generates other skills, it must itself embody the DNA it enforces.

Generation Protocol

Step 1: Domain Analysis

Analyze the target domain:

1. What is the primary output of this skill?
2. What inputs does it require?
3. What quality criteria apply?
4. Which tasks are deterministic (P1) vs. semantic (LLM)?

Ask the user a maximum of 4 questions (P4 rule), each with up to 3 choices. If the domain is clear enough, proceed without questions.

Step 2: Skill Architecture Design

Design the skill structure:

.claude/skills/{skill-name}/
├── SKILL.md              ← Main skill file (WHY + HOW)
└── references/           ← Supporting documents (WHAT/VERIFY)
    ├── {domain}-guide.md      ← Domain-specific guidance
    ├── {domain}-checklist.md  ← Quality checklist
    └── {domain}-examples.md   ← Before/after examples (if applicable)

Step 3: Generate SKILL.md

The generated SKILL.md must follow this template:

---
name: {skill-name}
description: {one-line description for skill matching}
# Optional — context isolation and agent type (see Selection Criteria below)
# context: fork          # omit for inline (default), add for isolated execution
# agent: general-purpose # only with context: fork — Explore | Plan | general-purpose | <custom-agent>
---

# {Skill Title}

{Brief description of what the skill does.}

## Inherited DNA
{Absolute criteria contextualized for this domain}

## Protocol
{Step-by-step execution protocol}

## Quality Gates
{Domain-specific quality criteria}

## P1 Enforcement
{List of deterministic validations, if any}

context: fork + agent Selection Criteria

These optional frontmatter fields control where and how the skill executes. Default is inline (no field needed).

Constraints — fork MUST NOT be used when:

• Skill writes to SOT directly (violates Absolute Criteria 2 single-writer)
• Skill requires sequential quality gate passage (L0→L1→L1.5→L2) with main context visibility
• Skill needs Bash but the specified agent lacks Bash tool access
• Skill is part of the main orchestration flow (router, resume, HITL gates)

agent field specifies which agent type runs the forked context. Only meaningful with context: fork:

• Explore — read-only codebase search (haiku model)
• Plan — architecture research, read-only
• general-purpose — full tool access, multi-step tasks
• {custom-agent} — any agent defined in .claude/agents/ (inherits that agent's model, tools, behavior)

Step 4: Generate Reference Files

Create supporting documents in references/:

• Domain guide: Detailed domain knowledge and best practices
• Checklist: Verification items for quality assurance
• Examples: Concrete examples of good/bad outputs (when applicable)

Step 5: Validate Generated Skill

Verify the generated skill:

• SKILL.md has valid frontmatter (name, description; optional: context, agent)
• Inherited DNA section present with all applicable genome components
• Protocol has clear, numbered steps
• Quality gates defined
• References directory populated
• No hardcoded paths (uses relative references)
• Language: internal instructions in English, user-facing in Korean
• Fork Safety P1 Validation (if context: fork in frontmatter): Run python3 .claude/hooks/scripts/validate_fork_safety.py --file <generated-SKILL.md> --project-dir <project-root> Must PASS all 5 rules (FS-1~FS-5). FAIL → fix violations before proceeding to Step 6.

Step 6: Register Skill

Inform the user:

1. Skill location: .claude/skills/{skill-name}/
2. How to trigger it (matching patterns from description)
3. Any required setup (dependencies, configuration)

Language Rules

• SKILL.md internal instructions: English (for AI performance)
• SKILL.md description (frontmatter): Korean (for user-facing matching)
• Reference files: English (domain knowledge for AI consumption)
• Generated output for users: Korean (user-facing reports)

Quality Checklist

• Generated skill follows AgenticWorkflow conventions
• DNA inheritance is complete (not just referenced)
• Steps are concrete and actionable
• P1 tasks identified and separated from LLM tasks
• No placeholder content — all sections are substantive
