Sensei

"A true master teaches not by telling, but by refining." - The Skill Sensei

Automates skill frontmatter improvement using the Ralph loop pattern - iteratively improving skills until they reach Medium-High compliance with passing tests, then checking token usage and prompting for action.

When to Use

• Improving a skill's frontmatter compliance score
• Adding trigger phrases and anti-triggers to skill descriptions
• Batch-improving multiple skills at once
• Auditing and fixing Low-adherence skills

Invocation Modes

Single Skill

Run sensei on azure-deploy

Multiple Skills

Run sensei on azure-security, azure-networking, azure-observability

By Adherence Level

Run sensei on all Low-adherence skills

All Skills

Run sensei on all skills

The Ralph Loop

For each skill, execute this loop until score >= Medium-High AND tests pass:

1. READ - Load plugin/skills/{skill-name}/SKILL.md, tests, and token count
2. SCORE - Run rule-based compliance check (see SCORING.md)
3. CHECK - If score >= Medium-High AND tests pass → go to TOKENS step
4. SCAFFOLD - If tests/{skill-name}/ doesn't exist, create from tests/_template/
5. IMPROVE FRONTMATTER - Add triggers, anti-triggers, compatibility (stay under 1024 chars)
6. IMPROVE TESTS - Update shouldTriggerPrompts and shouldNotTriggerPrompts to match
7. VERIFY - Run cd tests && npm test -- --testPathPattern={skill-name}
8. TOKENS - Check token budget, gather optimization suggestions
9. SUMMARY - Display before/after comparison with unimplemented suggestions
10. PROMPT - Ask user: Commit, Create Issue, or Skip?
11. REPEAT - Go to step 2 (max 5 iterations per skill)

Scoring Criteria (Quick Reference)

Target: Medium-High (triggers + anti-triggers present)

Frontmatter Template

---
name: skill-name
description: |
  [1-2 sentence description of what the skill does]
  USE FOR: [trigger phrase 1], [trigger phrase 2], [trigger phrase 3]
  DO NOT USE FOR: [scenario] (use other-skill), [scenario] (use another-skill)
---

IMPORTANT: Always use multi-line YAML format (|) for descriptions over 200 characters. Single-line descriptions become difficult to read, review, and maintain. See azure-ai, azure-functions for examples.

Keep total description under 1024 characters.

Test Scaffolding

When tests don't exist, scaffold from tests/_template/:

cp -r tests/_template tests/{skill-name}

Then update:

1. SKILL_NAME constant in all test files
2. shouldTriggerPrompts - 5+ prompts matching new frontmatter triggers
3. shouldNotTriggerPrompts - 5+ prompts matching anti-triggers

Commit Messages:

sensei: improve {skill-name} frontmatter

Constraints

• Only modify plugin/skills/ - these are the Azure skills used by Copilot
• .github/skills/ contains meta-skills like sensei for developer tooling
• Max 5 iterations per skill before moving on
• Description must stay under 1024 characters
• SKILL.md should stay under 500 tokens (soft limit)
• Tests must pass before prompting for action
• User chooses: Commit, Create Issue, or Skip after each skill

Flags

⚠️ Skipping integration tests speeds up the loop but may miss runtime issues. Consider running full tests before final commit.
