Missing README / runbook docs
Part of the Engineering practices check · fix arrives as a guide
What it is
The repository has no README covering how to run the project, or no runbook describing what to do when the production service misbehaves.
Why it matters
The cost lands on the worst day — a new engineer onboarding, or whoever is on call at 3am for a service they did not build. Undocumented knowledge is also single-person knowledge.
How to fix it
Write down how to run it locally, what environment variables it needs, and how to deploy it. For the runbook, one page per recurring alert with the first three things to check beats a comprehensive document nobody finishes.
