Land and Deploy

Complete landing pipeline: merge the PR, wait for CI, verify the deployment, run a health check.

Picks up where /ship left off. /ship creates the PR. This command merges it and verifies production.

Non-interactive by default. The user said "land it" — so land it. Stop only for the critical readiness gate and hard blockers.

Instructions

Step 1: Pre-flight

# Verify GitHub CLI is authenticated
gh auth status

# Detect PR from current branch (or use argument if provided)
gh pr view --json number,state,title,url,mergeStateStatus,mergeable,baseRefName,headRefName

Stop conditions:

• GitHub CLI not authenticated → "Run gh auth login first"
• No PR exists → "No PR found for this branch. Run /ship first."
• PR already merged → "PR is already merged."
• PR is closed → "PR is closed. Reopen it first."

---

Step 2: CI Status Check

# Check current CI status
gh pr checks --json name,state,status,conclusion

# Check for merge conflicts
gh pr view --json mergeable -q .mergeable

Stop conditions:

• Required checks FAILING → show failing checks, stop
• mergeable is CONFLICTING → "PR has merge conflicts. Resolve them and push before landing."
• Required checks PENDING → proceed to Step 3 (wait for CI)
• All checks passing → skip to Step 3.5 (readiness gate)

---

Step 3: Wait for CI (if pending)

# Watch CI checks with 15-minute timeout
gh pr checks --watch --fail-fast

• CI passes → continue to Step 3.5
• CI fails → stop, show failures
• Timeout (15 min) → "CI has been running for 15 minutes. Investigate manually."

Record CI wait duration for the deploy report.

Step 3.5: Pre-Merge Readiness Gate

This is the one critical confirmation before an irreversible merge. Collect all evidence, then get explicit approval.

Review staleness check

# How many commits since the last review in this branch?
git log --oneline $(git merge-base HEAD origin/main)..HEAD | wc -l

# What changed after any review was done?
git log --oneline -10
