Grade a Skill
A skill is graded by running it, not by reading it.
Rubric (10 points)
- Trigger clarity (2): does the description say exactly WHEN to invoke it? Would an agent fire it on the right prompts and not on the wrong ones?
- Actionability (2): are steps executable as written — real commands, real paths, decision rules — or vague advice ("check the logs")?
- Round-trip economy (2): can an agent follow it with minimal tool calls? No steps that force re-discovery of things the skill could state.
- Failure handling (2): does it say what to do when a step fails (auth missing, empty result, flaky env)?
- Scope discipline (2): covers its one job; no bloat, no duplicated general knowledge the model already has; under ~100 lines or split into references.
Process
- Read the SKILL.md and any bundled scripts/references.
- Write 3 realistic task prompts the skill should handle + 1 it should NOT trigger on.
- Dispatch a fresh agent per prompt with only the skill as guidance; observe where it stalls, guesses, or asks avoidable questions.
- Score each rubric line with one sentence of evidence from the runs.
Report
score/10, per-criterion breakdown, then the 3 highest-impact concrete edits (quote the line to change and the replacement).
- A 10/10 requires all 4 test runs to succeed without the agent needing knowledge the skill omitted.
