skill-extension

Usage

Use this skill when creating a new skill or improving an existing one under copilot/skills/.

Responsibility

This skill owns skill authoring quality:

• Scope: structure, frontmatter validity, trigger clarity, and execution steps.
• Out of scope: solving unrelated product features.

Required Conventions

• Path: copilot/skills//SKILL.md
• Frontmatter required:
  • name
  • description (single quotes, 10-1024 chars)
• One skill should own one primary responsibility.
• Operational guidance is written in English.

Protocol

1. Define purpose

• Name the one core job this skill performs.
• Reject mixed responsibilities.

2. Define trigger

• Specify user intents or conditions that should activate this skill.

3. Draft executable protocol

• Write short, ordered steps that can be directly executed.
• Include expected output contract.

4. Validate frontmatter and naming

• name matches folder name.
• description meets length and quote rules.

5. Add integration notes

• Mention related skills only when handoff is clear.
• Avoid duplicated workflows across skills.
