keel from broomva/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Measure whether a codebase's verification actually touches the world, or whether it is checking itself. Keel gathers the verification edges it can read in a target (GitHub Actions, CircleCI, GitLab CI, Travis, package scripts, Makefile, Rakefile, pyproject and a dozen tool configs) — and reports the surfaces it recognised but could not parse, so blindness never passes for absence. It classifies each edge as anchored, self-referential, or unknown by asking whether the actor being verified can…
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
# Keel A ship's keel is the reference line everything else is measured from. It is also what keeps the ship from capsizing — an even keel is a stability property, not a decoration. Keel measures one thing: > **A check is only a check if the signal it reads comes from somewhere the > thing being checked cannot write to.** Most verification in an agent-maintained codebase fails this. An LLM reviews what an LLM wrote. A doc is validated against another doc. A status field says "passed" because something set it to "passed". The pipeline is green and nothing has been verified. ## Where the predicate comes from Silver & Sutton (*Welcome to the Era of Experience*, 2025) argue that agents must replace human-prejudged reward with **grounded** signals, "that arise from the environment itself", because a human rater imposes "an impenetrable ceiling on the agent's performance" and, ungrounded, an agent "will become an echo chamber of existing human knowledge." Grounded and independent are not the same property, and the paper only asks for the first. Its own signal inventory — "cost, error rates … profit, sales … …

How to install
mdr add broomva/skills/keel@sha256:91c91ad46017c8daThe line at the top of this page pins the label v1.0.0, 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.
