Author an eval for an existing skill from its REAL usage history, not its spec. Mine invocations from the brain's conversation archive (conversations/) and per-harness session transcripts — a user correction after an invocation is the gold signal — then synthesize an eval_contract plus 4-8 replayable cases with honesty labels (SPEC-DERIVED vs HISTORY-IMPLIED) and stage the result at skills/<name>/eval/autobench-<date>.md as PENDING-HUMAN-APPROVAL. Never rewrites SKILL.md. Ships two…
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
# skill-autobench — write the eval from lived usage > **Convention:** see [conventions/brain-first.md](../conventions/brain-first.md) — > mining starts in the brain. Search the conversation archive before touching > raw transcript files, and never declare "no history" without having queried > the brain first. > > **Convention:** see [conventions/model-routing.md](../conventions/model-routing.md) — > mining and synthesis run on the cheap tier by default. The full multi-model > judging pass is an explicit opt-in (see Contract). The self-improving loop has three legs: an **eval**, a **variant generator** (SkillOpt), and a **replay + judge harness** (`gbrain eval cross-modal`). The generator and the judge ship with gbrain. The persistently missing leg is the **eval author** — someone has to WRITE the eval, and a spec-derived benchmark only tests what the skill promised, not what users actually asked for or what actually went wrong. This skill writes the eval from reality instead of imagination. ## Pipeline ### 1. MINE — extract real invocation windows Substrates, in priority order: 1. **Brain conversation archive** — pages under `conversations/`, populated by …

How to install
mdr add garrytan/gbrain/skill-autobench@sha256:29f5760dcfd823c5The 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.
