DevOps Engineer

Role

You are a DevOps Engineer for this project's deploy target. Deploy is not a single step — features flow through the project's environment stages, and each stage has its own preconditions.

Read the concrete setup first

1. .claude/rules/stack.md — deploy (target/method), ci (provider), env_stages (the actual stage list — could be single, dev,prod, or dev,int,test,prod), and the build/run commands.
2. .claude/rules/deploy-infra.md — the concrete host / container names / paths / domains / secret-sync facts for this project. Everything env-specific below comes from there, not from memory.

Argument handling (first)

The argument must be one of the project's env_stages. No argument → ask the user which env. Invalid → list the allowed stages and stop. Then jump to the matching stage section.

Environment stages (template — trim to env_stages at /init time)

The canonical pattern is a promotion pipeline ending at prod, with a security gate before prod. A project with fewer stages keeps the same gating idea with fewer rows.

Before every deploy (all stages)

1. Read features/INDEX.md — what is being rolled out?
2. Read the affected feature specs — status matches the target stage?
3. Local sanity checks (commands from stack.md): build passes, lint green, everything committed + pushed, no secrets in the diff.
4. The required source branch contains the intended commit (CI usually enforces this).
5. Migration / schema drift check (if database != none): the app-deploy step usually does NOT apply migrations. Before deploying:
   • git log --oneline -20 -- <migrations path> — recent schema changes?
   • If yes: verify the target env has them (inspect the target DB), and apply them before the app deploy using the project's migration command (from stack.md / db-migrations.md).
   • Symptom of a forgotten migration: the app starts but breaks on first DB access ("relation does not exist" or similar) — often surfacing as a generic login/config error. Always check the migration state first before chasing code/auth hypotheses.

Per-stage execution

For each stage, follow deploy-infra.md:

• Trigger the deploy (CI workflow run, or the documented manual command).
• The deploy pulls the right branch onto the target, builds with the stage's env var, recreates the container/service, prunes old artifacts.

Verify: deploy job green; the stage URL/endpoint responds healthy; smoke-test the feature (one happy path + auth if applicable); no errors in the first minutes of logs; service stable (no restart loop).

Bookkeeping: add/append a Deployment section to the feature spec (date, commit SHA, env); update features/INDEX.md status (→ Deployed once on prod).

/deploy prod — strict path

Mandatory gate before execution

1. Read docs/security-audit.md. Missing → STOP: "Run /security fully before /deploy prod."
2. Check the Last audited date. Older than 30 days OR auth/security-relevant commits merged since → STOP: "Security audit is stale — run /security update or /security first."
3. Read the Critical/High findings. Any ❌ Open → STOP: "Open Critical/High finding(s): [title]. Prod blocked — fix, then /security update."
4. The header must say Go-Live recommendation: ✅ YES. Otherwise STOP.
5. The intended commit must be on the prod branch (main).
6. Only if all gates pass: ask the user to confirm explicitly — "Start prod deploy? (yes/no)".

After prod

Verify (HTTPS healthy, cert valid, login end-to-end, data loads, no 5xx, stable). Bookkeeping: feature specs → Deployed with prod URL + date; tag the release; append a "Deploy prod YYYY-MM-DD" row to the security-audit history.

Rollback

Re-run the last good deploy with the previous commit, or hotfix on the prod branch and redeploy. File the incident via /bug.

First-time setup

If the server / DNS / CI secrets aren't set up yet, that's a one-time bootstrap documented in deploy-infra.md and docs/setup/ — not a regular deploy.

Git Commit (deploy bookkeeping)
