Skill Creator Enhanced

Skill Creator Enhanced

Create production-grade skills that extend Claude's capabilities.

How This Skill Works

User: "Create a skill for X"
       ↓
Claude Code uses this meta-skill as guidance
       ↓
Follow Domain Discovery → Ask user clarifying questions → Create skill

Generated skill with embedded domain expertise

This skill provides guidance and structure for creating skills. Claude Code:

1. Uses this skill's framework to discover domain knowledge
2. Asks user for clarifications about THEIR specific requirements
3. Decides how to structure the generated skill based on domain needs

What This Skill Does

• Guides creation of new skills from scratch
• Helps improve existing skills to production quality
• Provides patterns for 5 skill types (Builder, Guide, Automation, Analyzer, Validator)
• Ensures skills encode procedural knowledge + domain expertise

What This Skill Does NOT Do

• Test skills in production environments
• Deploy or distribute skills
• Handle skill versioning/updates after creation
• Create requirement-specific skills (always create reusable intelligence)

Domain Discovery Framework

Key Principle: Users want domain expertise IN the skill. They may not BE domain experts.

Phase 1: Automatic Discovery (No User Input)

Proactively research the domain before asking anything:

Sources priority: Official docs → Library docs (Context7) → GitHub → Community → WebSearch

Phase 2: Knowledge Sufficiency Check

Before asking user anything, verify internally:

- [ ] Core concepts understood?
- [ ] Best practices identified?
- [ ] Anti-patterns known?
- [ ] Security considerations covered?
- [ ] Official sources found?

If ANY gap → Research more (don't ask user for domain knowledge)
Only if CANNOT discover (proprietary/internal) → Ask user

Phase 3: User Requirements (NOT Domain Knowledge)

Only ask about user's SPECIFIC context:

The skill contains domain expertise. User provides requirements.

Required Clarifications

Ask about SKILL METADATA and USER REQUIREMENTS (not domain knowledge):

Skill Metadata

1. Skill Type - "What type of skill?"

2. Domain - "What domain or technology?"

User Requirements (After Domain Discovery)

3. Use Case - "What's YOUR specific use case?"

• Not "what can it do" but "what do YOU need"

4. Tech Stack - "What's YOUR environment?"

• Languages, frameworks, existing infrastructure

5. Existing Resources - "Any scripts, templates, configs to include?"

6. Constraints - "Any specific requirements or limitations?"

• Performance, security, compliance specific to user's context

Note

• Questions 1-2: Ask immediately
• Domain Discovery: Research automatically after knowing domain
• Questions 3-6: Ask after discovery, informed by domain knowledge
• Question pacing: Avoid asking too many questions in a single message. Start with most important, follow up as needed.

Core Principles

Reusable Intelligence, Not Requirement-Specific

Skills must handle VARIATIONS, not single requirements:

❌ Bad: "Create bar chart with sales data using Recharts"
✅ Good: "Create visualizations - adaptable to data shape, chart type, library"

❌ Bad: "Deploy to AWS EKS with Helm"
✅ Good: "Deploy applications - adaptable to platform, orchestration, environment"

Identify what VARIES vs what's CONSTANT in the domain. See references/reusability-patterns.md.

Concise is Key

Context window is a public good (~1,500+ tokens per skill activation). Challenge each piece:

• "Does Claude really need this explanation?"
• "Does this paragraph justify its token cost?"

Prefer concise examples over verbose explanations.

Appropriate Freedom

Match specificity to task fragility:

Progressive Disclosure

Three-level loading system:

1. Metadata (~100 tokens) - Always in context (description ≤1024 chars)
2. SKILL.md body (<500 lines) - When skill triggers
3. References (unlimited) - Loaded as needed by Claude

Anatomy of a Skill

Generated skills are zero-shot domain experts with embedded knowledge.

skill-name/
├── SKILL.md (required)
│   ├── YAML frontmatter (name, description, allowed-tools?, model?)
│   └── Procedural knowledge (workflows, steps, decision trees)
└── Bundled Resources
    ├── references/   - Domain expertise (structure based on domain needs)
    ├── scripts/      - Executable code (tested, reliable)
    └── assets/       - Templates, boilerplate, images

SKILL.md Requirements

What Goes in references/

Embed domain knowledge gathered during discovery:

Structure references/ based on what the domain needs.

Large files: If references >10k words, include grep search patterns in SKILL.md for efficient discovery.

When to Generate scripts/

Generate scripts when domain requires deterministic, executable procedures:

Decision: If procedure is complex, error-prone, or needs to be exactly repeatable → create script. Otherwise → document in SKILL.md or references/.

When to Generate assets/

Generate assets when domain requires exact templates or boilerplate:

What NOT to Include

• README.md (SKILL.md IS the readme)
• CHANGELOG.md
• LICENSE (inherited from repo)
• Duplicate information

What Generated Skill Does at Runtime

User invokes skill → Gather context from:
  1. Codebase (if existing project)
  2. Conversation (user's requirements)
  3. Own references/ (embedded domain expertise)
  4. User-specific guidelines
→ Ensure all information gathered → Implement ZERO-SHOT

Include in Generated Skills

Every generated skill should include:

## Before Implementation

Gather context to ensure successful implementation:

| Source | Gather |
|--------|--------|
| **Codebase** | Existing structure, patterns, conventions to integrate with |
| **Conversation** | User's specific requirements, constraints, preferences |
| **Skill References** | Domain patterns from `references/` (library docs, best practices, examples) |
| **User Guidelines** | Project-specific conventions, team standards |

Ensure all required context is gathered before implementing.
Only ask user for THEIR specific requirements (domain expertise is in this skill).

Type-Aware Creation

After determining skill type, follow type-specific patterns:

Skill Creation Process

Metadata → Discovery → Requirements → Analyze → Embed → Structure → Implement → Validate

See references/creation-workflow.md for detailed steps.

Quick Steps

1. Metadata: Ask skill type + domain (Questions 1-2)
2. Discovery: Research domain automatically (Phase 1-2 above)
3. Requirements: Ask user's specific needs (Questions 3-6)
4. Analyze: Identify procedural (HOW) + domain (WHAT) knowledge
5. Embed: Put gathered domain expertise into references/
6. Structure: Initialize skill directory
7. Implement: Write SKILL.md + resources following type patterns
8. Validate: Run scripts/package_skill.py and test

SKILL.md Template

---
name: skill-name                    # lowercase, hyphens, ≤64 chars
description: |                      # ≤1024 chars
  [What] Capability statement.
  [When] Use when users ask to <triggers>.
allowed-tools: Read, Grep, Glob     # optional: restrict tools
