Discipline for shipping changes reversibly, decouple deploy (code reaches production) from release (users see it) with feature flags, roll out progressively, and define the automated rollback trigger before shipping, not during the incident. Use when the user asks how to deploy a risky change, choose between canary/blue-green/rolling deployment, ship behind a feature flag, plan a rollback strategy, or asks "how do we ship this safely.".
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
# Safe Deployment Every deploy is reversible **before** it becomes visible. That means treating "code reaches production" and "users see the new behaviour" as two separate, independently controllable events, rolling exposure out in steps instead of all at once, and deciding what "unhealthy, roll back" means while writing the deploy plan, not while paged at 3am reading dashboards for the first time. ## Phase 1: Decouple deploy from release Before choosing a rollout strategy, decide whether this change needs a **feature flag**: - If the change is risky, user-visible, or its blast radius is unclear; put it behind a flag. The code ships to production dark (compiled in, disabled), and "release" becomes flipping a config value, not another deploy. - A flagged change can be enabled for an internal allowlist first, then a percentage of traffic, then everyone; all without a redeploy, and all instantly reversible by flipping the flag back off. - Flags accumulate cost (branches to test, config to reason about); remove a flag once the change has fully rolled out and stabilized; a flag left in forever is dead code with a stated deadline that got ignored. …

How to install
mdr add aethrox/doctrine/safe-deployment@sha256:7e0f19316a29a693The line at the top of this page pins the label git:20260809.2a45dbb, 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.
