release-engineering from majiayu000/spellbook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Plan and verify software releases with versioning, changelogs, release branches, feature flags, canaries, migration gates, rollback, deployment checks, and release readiness. Use when preparing a release, shipping a risky PR, coordinating app/backend/database rollout, recovering from a bad deploy, or defining release policy for a repo.

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

# Release Engineering

## Purpose

Use this skill to turn "ready to merge" into a controlled release. It connects code, data, config, deployment, monitoring, and rollback.

## Release Classification

Classify the release before choosing gates:

| Type | Extra Gates |
|---|---|
| Patch fix | focused regression test, rollback proof |
| Feature release | feature flag, docs/changelog, product acceptance |
| API or SDK change | versioning, deprecation, compatibility tests |
| Database migration | `data-contract-migrations`, backup, backfill, recovery |
| Config or secret change | `config-secrets-environments`, rotation, drift check |
| Infrastructure change | canary, health checks, capacity and rollback |

## Release Plan

For non-trivial releases, require:

1. Version or release identifier.
2. Changelog entries grouped by user impact.
3. Build artifacts and provenance.
4. Migration and config gates.
5. Canary or staged rollout plan.
6. Monitoring dashboard and alert expectations.
7. Rollback or roll-forward command.
8. Owner, decision time, and abort criteria.

## Verification

Use fresh commands from the current session. Typical gates:

```bash
git status --short
…

How to install

The exact contents, by fingerprint

mdr add majiayu000/spellbook/release-engineering@sha256:d40a3d93ef72b30a

The line at the top of this page pins the label git:20260626.97a677e, 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.
