Judge a canary release against a concurrent baseline using pre-set metric gates, automatic rollback, and statistically honest windows. Use when a deploy is rolling out to a slice of production traffic and you must decide pass, hold, or revert.
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
# Canary analysis A canary sends the new version to a small slice of live traffic and compares its behavior against the old version, so a regression hits a fraction of users instead of all of them. The judgment goes wrong when the comparison is unfair, the sample is too small to mean anything, or a human eyeballs a green dashboard and ships on the first good-looking minute. Rigor here is the difference between catching a regression and blessing one. ## Method 1. **Compare against a concurrent baseline, not history.** Run the old version as a control on the same population in the same window, and diff the canary against it. Comparing to yesterday's numbers lets time-of-day, traffic mix, and weekend effects masquerade as a regression or hide a real one. 2. **Set metric gates before the deploy.** Pick error rate, latency at p50 and p99, CPU and memory, and one business metric such as checkout rate; declare the direction and threshold for each up front. Tools like Spinnaker's Kayenta score these into a single verdict. 3. **Wait for a minimum sample before scoring.** A canary on 1% of traffic for …

How to install
mdr add amey-thakur/ai-skills/canary-analysis@sha256:04ae20968fd0dce6The line at the top of this page pins the label git:20260728.fac4544, 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.
