eval-skills SKILL.md skillA

This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.

eval-skills from dzhng/duet-agent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Eval and improve a skill against golden cases — run the target skill blind in a fresh, context-free subagent on each example input, grade the artifact against the expected outcome, and let the gaps drive the edits. Use when the user wants to test/eval/improve/harden a skill, says "this skill keeps producing X / keeps missing Y", or hands a skill plus example input→expected-output pairs. Pairs with [write-skills](../write-skills/SKILL.md) (the authoring principles every fix obeys).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Eval Skills

Treat a skill like a function under test. Feed it example inputs in a clean
room, check the artifacts against what good looks like, and let the failures
drive the edits. The eval is only honest if the run is **blind**: the agent
executing the skill must carry none of this conversation's context and must
never see the expected output. Leak either and you are teaching to the test.

## Inputs you need — refuse without them

Confirm all three before spawning anything. If any is missing or
unresolvable, stop and tell the user *exactly which one* and what a good
version looks like. Do not invent cases, guess intent, or eval against a
fuzzy wish.

- **Target skill** — must resolve to a real `SKILL.md`. If you can't find it,
  list the skills you can see and ask which one they mean.
- **At least one golden case** — a concrete input the skill will actually
  receive: a screenshot, a prompt, a file, a scene. "Improve write-spec"
  with no input attached is not a case.
- **The bar per case** — the outcome a good artifact achieves and the smells
  that would make it bad, *not* an exhaustive parts list. The skill's

How to install

The exact contents, by fingerprint
mdr add dzhng/duet-agent/eval-skills@sha256:2e9bf33371fce396

The line at the top of this page pins the label git:20260717.934babf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
