Pulser — Skill Diagnostics & Testing
Run pulser to diagnose and test Claude Code skills, then present results conversationally.
How to Run
pulser --format json ~/.claude/skills/
If pulser is not installed globally, use:
npx pulser-cli --format json ~/.claude/skills/
For a single skill:
pulser --format json --skill <name> ~/.claude/skills/
How to Present Results
- Run the command above and capture JSON output
- Parse the JSON result
- Present a conversational summary:
- Total skills, score, healthy/warning/error counts
- Top issues (max 5) with skill name + issue
- "Fix these issues?" prompt
- If user says yes, apply prescriptions one by one:
- Show the before/after diff
- Ask for confirmation
- Apply via Edit tool (NOT via --fix flag — you have more context than the CLI)
Summary Format
스킬 진단 완료:
📊 30개 스킬 스캔 | Score: 76/100

주요 이슈:
1. cardnews — Gotchas 없음, allowed-tools 미설정
2. geo-audit — 338줄 단일파일, Gotchas 없음
3. detailpage — Gotchas 없음, allowed-tools 미설정

When Fixing
Use the prescription data from JSON. For each fix:
- Read the actual SKILL.md file
- Apply the suggested change using Edit tool
- Verify the change makes sense in context
- You can improve on the template prescriptions — you understand the skill's purpose
Eval — Skill Testing
Run pulser eval to test skills that have eval.yaml files:
pulser eval --format json
For a single skill:
pulser eval --format json --skill <name>
Present eval results conversationally:
- Total tests, passed, failed, regressions
- Failed test details with assertion info
- Regression warnings (previously passing tests that now fail)
Gotchas
- Do not dump raw JSON to the user — always summarize conversationally
- If pulser is not installed, suggest
npm install -g pulser-clifirst - For --fix operations, use Edit tool directly rather than CLI --fix (you have better context)
- Score below 50 is critical — highlight urgently
- Don't fix all skills at once — group by priority, confirm with user
- Eval only works for text-output skills (analysis, research, generation, reference) — execution-type skills cannot be tested this way
- Eval requires Claude Code CLI installed (
claude -pmust be available)
