Creating Claude Skills

Knowledge for creating and maintaining Claude commands and skills.

Mechanic Skill System

This project uses a three-prefix taxonomy:

See ../../AGENTS.md for full system documentation.

Creating a New Action

To add a new action (e.g., "deploy"):

1. Create commands/c-deploy.md with explicit steps
2. Create skills/s-deploy/SKILL.md with detailed guidance
3. Add bidirectional links between them

Creating New Knowledge

To add new context (e.g., "blizzard-api"):

1. Create skills/k-blizzard-api/SKILL.md
2. No command needed - the skill IS the context loader

| Request type | Load reference |

Core Principles

1. Progressive Loading

Skills load in stages:

• Stage 1: Name + description (always loaded)
• Stage 2: SKILL.md body (when skill is relevant)
• Stage 3: References (only when explicitly needed)

Design for minimal initial context, deep references.

2. Clear Triggers

Description should include trigger words that help Claude know when to use this skill.

3. Self-Contained References

Each reference file should be independently useful without requiring other files.

4. Actionable Content

Focus on rules, patterns, and examples—not background explanation.
