Interview the user to decide what a skill's eval should test, then build the spec and iterate until the skill ships. Use when the user wants help designing a skill's eval, has a skill with no eval, or wants to find what an existing eval misses.
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
# Grill Skill Interview the user to design a skill's eval, then loop run → diagnose → improve until it ships. Requires `caliper` (`pipx install caliper-eval` if missing). Commands, spec skeleton, and task-writing rules: [REFERENCE.md](REFERENCE.md). An eval answers four questions, and the interview covers each: - **Fires**: does the agent reach for the skill when it should, and only then? Tested with `activates:` and trigger probes. Fixed in the `description`. - **Works**: once it fires, does it do the job? Tested with `expect:` / `assert:`. Fixed in the body. - **Earns**: does it beat the agent without it? Tested against the control: the declared neighbourhood with this skill removed. A task the control passes too is fixed in the task. - **Holds**: does it stay good across edits? Tested by comparing each new full run against the previous one. ## Entry point `/grill-skill [path]`: optional path to a `SKILL.md`. - **Path given**: use it. - **No path**: look for `SKILL.md` in the cwd; if found, confirm before proceeding, else ask where it is. ## Phase 1 — Understand …

How to install
mdr add edonadei/caliper/grill-skill@sha256:1b6c839e49a27950The line at the top of this page pins the label git:20261009.dff52c2, 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.
