Instruction Creator

This skill guides the creation of effective custom instruction files that help GitHub Copilot follow project conventions and domain-specific logic.

Workflow

  1. Define Scope: Identify the purpose and the files the instructions should apply to (e.g., 
    **/*.ts
    ).
  2. Initialize: Use the 
    scripts/init_instruction.py
    script to create the boilerplate. 
    python skills/instruction-creator/scripts/init_instruction.py "my-new-instruction" --description "Description here" --applyTo "**/*.ext"
  3. Draft Content: Follow the guidelines to fill in the sections.
  4. Use Templates: Refer to templates for standard structures.
  5. Semantic Linking: Ensure you link to relevant Skills in the 
    Workflow
    section.
    • Example: 
      To perform [Task], execute the [Skill Name](skills/<skill-name>/SKILL.md).
  6. Validate: Test the instructions with Copilot to ensure they are clear and actionable.

Core Principles

  • Policy Maker: Instructions define the "What" and "How" (decision logic and standards).
  • The 5 Sections: Effective instructions include: Overview, Tech Stack, Structure, Guidelines, and Resources.
  • Concise & focused: Avoid fluff; use imperative language. Limit files to ~500 lines.
  • Actionable: Provide concrete "Good" and "Bad" code examples and clear steps.
  • Linked: Connect instructions to the skills that execute them and internal automation scripts.

Resources

  • Guidelines: Detailed rules for frontmatter, style, and linking.
  • Templates: Ready-to-use markdown structures.
  • scripts/init_instruction.py
    : Automation for creating new files.
