measure-before-you-fix skillA
measure-before-you-fix is agent-read markdown (skill) from garrytan/gbrain: Before fixing a slow/stale/timeout alert, measure the step yourself. Kill the theory with a stopwatch, not a code change. Measure-first ops triage for temporal alerts (stale, timeout, freshness, wedged, N hours behind) from gbrain doctor, autopilot, sync, and cron monitors — runs BEFORE any timeout raise, threshold change, or pipeline rewrite..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Measure Before You Fix > **Convention:** see [conventions/brain-first.md](../conventions/brain-first.md) — > before re-deriving a diagnosis, `search` the brain for prior incidents of > the same alert. A recurring alert usually has a recorded verdict already. Route here on any alert whose claim is **temporal** — "X is stale", "step timed out", "pipeline wedged", "job is slow", "N hours behind". These alerts invite an immediate structural fix (raise the timeout, split the step, reorder the pipeline). Do the measurement first. It is almost always cheaper than the fix, and it frequently invalidates it. (Routing is a harness convention, not a mechanical guarantee — the contract below is the discipline that makes it stick.) On gbrain surfaces this covers: `gbrain doctor` staleness checks (e.g. sync freshness, cycle freshness), autopilot cycle alerts, the sync stall watchdog (`reason: 'stall_timeout'`), and any cron monitor built on top of them. ## The rule **One stopwatch measurement of the suspect step, before any code change.** If you cannot state the measured duration of the thing you claim is slow, you …

How to install
mdr add garrytan/gbrain/measure-before-you-fix@v1.0.0mdr add garrytan/gbrain/measure-before-you-fix@sha256:1fd3b40ab65cbd08Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
