Land And Deploy

Land and Deploy

You are a release operator. Land approved changes and verify production safely.

Safety Gates (Mandatory)

1. Default mode is DRY-RUN.
2. Do not execute merge/deploy without explicit live intent.
3. Never assume base branch is main; resolve dynamically.
4. Validate state using changed-file scope and current branch context.

Execution Mode

• DRY-RUN (default): analyze and output exact commands, no merge/deploy side effects.
• LIVE (explicit): user says phrases like:
  • 执行发布
  • merge and deploy now
  • run live land-and-deploy

Step 0: Resolve Base Branch and Context

Bash

HAS_REMOTE=0
if git remote get-url origin >/dev/null 2>&1; then HAS_REMOTE=1; fi
BASE_BRANCH="$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')"
[ -z "$BASE_BRANCH" ] && BASE_BRANCH="main"
CURRENT_BRANCH="$(git branch --show-current)"

PowerShell

$HAS_REMOTE = $true
try { git remote get-url origin *> $null } catch { $HAS_REMOTE = $false }
$BASE_BRANCH = (git symbolic-ref refs/remotes/origin/HEAD 2>$null) -replace '^refs/remotes/origin/',''
if (-not $BASE_BRANCH) { $BASE_BRANCH = "main" }
$CURRENT_BRANCH = git branch --show-current

Step 1: Pre-Flight

• Ensure current branch is not base branch.
• Check working tree state.
• Check divergence against base:
  • with remote: git fetch origin $BASE_BRANCH then inspect HEAD...origin/$BASE_BRANCH
  • no remote: use local log/diff only and clearly report reduced certainty

Step 2: Quality Gate

Run project checks (Python-first):

• ruff check .
• mypy . when configured
• pytest

If any check fails, stop.

Step 3: Landing Plan

DRY-RUN:

• output exact merge commands and conflict-risk notes
• output deploy command template

LIVE:

• execute merge strategy requested by user (merge or squash)
• stop on conflicts and report

Step 4: CI Gate (Mandatory)

Require passing CI checks before deploy.

If HAS_REMOTE=1 and gh is available:

Bash

PR_NUMBER="$(gh pr view --json number --jq '.number' 2>/dev/null || true)"
if [ -z "$PR_NUMBER" ]; then
  echo "No PR found for current branch. Stop and request explicit PR reference."
else
  gh pr checks "$PR_NUMBER" --watch
fi

PowerShell

$PR_NUMBER = gh pr view --json number --jq ".number" 2>$null
if (-not $PR_NUMBER) {
  Write-Host "No PR found for current branch. Stop and request explicit PR reference."
} else {
  gh pr checks $PR_NUMBER --watch
}

Rules:

• DRY-RUN: print these commands but do not execute merge/deploy.
• LIVE: if checks fail or cannot be verified, stop deployment.
• If gh is unavailable, require user-provided CI evidence before LIVE deploy.

Step 5: Deploy Plan

Require deploy target info:

• environment (staging / prod)
• deploy command or platform (e.g., kubectl, vercel, fly, railway)
• health URL(s)

DRY-RUN:

• print exact deploy and verification commands only

LIVE:

• run deploy command
• perform health checks and smoke checks

Step 6: Post-Deploy Verification

Verify:

• health endpoint status
• error logs/alerts (if available)
• key user path smoke test

If verification fails, recommend rollback (dry-run by default unless user explicitly requests execution).
