Skill Creator

Skill Creator

This skill wraps Anthropic's official skill-creator with local context.

Skill Types

User skills (~/.claude/skills/<name>/):

• Portable across all projects
• General-purpose utilities (file-nav, code-search, github, etc.)
• NOT tied to any specific repository

Project skills (.claude/skills/<name>/ in repo root):

• Repository-specific knowledge and workflows
• Codebase conventions, testing patterns, deployment procedures
• Only available within that project

Workflow

1. Determine Skill Type

Before creating a skill, clarify with the user:

• User skill: "Should this skill be available across all your projects?"
• Project skill: "Is this specific to the current repository?"

If unclear, ask using AskUserQuestion.

2. Fetch Upstream Guidance

For skill creation best practices, fetch Anthropic's skill-creator:

WebFetch: https://raw.githubusercontent.com/anthropics/skills/main/skills/skill-creator/SKILL.md

For specific patterns:

• Workflows: https://raw.githubusercontent.com/anthropics/skills/main/skills/skill-creator/references/workflows.md
• Output patterns: https://raw.githubusercontent.com/anthropics/skills/main/skills/skill-creator/references/output-patterns.md

3. Create the Skill

Apply upstream guidance with these local defaults:

4. Key Reminders

From upstream skill-creator (fetch for full details):

• Concise is key: Context window is shared; only add what Claude doesn't know
• Progressive disclosure: SKILL.md body < 500 lines; use references/ for details
• Frontmatter description: Must include "when to use" - body loads AFTER triggering
• No extra docs: No README.md, CHANGELOG.md, etc.
