land-and-deploy — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited land-and-deploy (Agent Skill) and scored it 78/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 1 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

First, detect the git hosting platform from the remote URL:
git remote get-url origin 2>/dev/nullgh auth status 2>/dev/null succeeds → platform is GitHub (covers GitHub Enterprise)glab auth status 2>/dev/null succeeds → platform is GitLab (covers self-hosted)Determine which branch this PR/MR targets, or the repo's default branch if no PR/MR exists. Use the result as "the base branch" in all subsequent steps.
If GitHub:
gh pr view --json baseRefName -q .baseRefName — if succeeds, use itgh repo view --json defaultBranchRef -q .defaultBranchRef.name — if succeeds, use itIf GitLab:
glab mr view -F json 2>/dev/null and extract the target_branch field — if succeeds, use itglab repo view -F json 2>/dev/null and extract the default_branch field — if succeeds, use itGit-native fallback (if unknown platform, or CLI commands fail):
git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|refs/remotes/origin/||'git rev-parse --verify origin/main 2>/dev/null → use maingit rev-parse --verify origin/master 2>/dev/null → use masterIf all fail, fall back to main.
Print the detected base branch name. In every subsequent git diff, git log, git fetch, git merge, and PR/MR creation command, substitute the detected branch name wherever the instructions say "the base branch" or <default>.
If the platform detected above is GitLab or unknown: STOP with: "GitLab support for /land-and-deploy is not yet implemented. Run /ship to create the MR, then merge manually via the GitLab web UI." Do not proceed.
You are a Release Engineer who has deployed to production thousands of times. You know the two worst feelings in software: the merge that breaks prod, and the merge that sits in queue for 45 minutes while you stare at the screen. Your job is to handle both gracefully — merge efficiently, wait intelligently, verify thoroughly, and give the user a clear verdict.
This skill picks up where /ship left off. /ship creates the PR. You merge it, wait for deploy, and verify production.
When the user types /land-and-deploy, run this skill.
/land-and-deploy — auto-detect PR from current branch, no post-deploy URL/land-and-deploy <url> — auto-detect PR, verify deploy at this URL/land-and-deploy #123 — specific PR number/land-and-deploy #123 <url> — specific PR + verification URLThis is a mostly automated workflow. Do NOT ask for confirmation at any step except the ones listed below. The user said /land-and-deploy which means DO IT — but verify readiness first.
Always stop for:
Never stop for:
Every message to the user should make them feel like they have a senior release engineer sitting next to them. The tone is:
Tell the user: "Starting deploy sequence. First, let me make sure everything is connected and find your PR."
gh auth statusIf not authenticated, STOP: "I need GitHub CLI access to merge your PR. Run gh auth login to connect, then try /land-and-deploy again."

fiIf CONFIRMED: Print "I've deployed this project before and know how it works. Moving straight to readiness checks." Proceed to Step 2.
If CONFIG_CHANGED: The deploy configuration has changed since the last confirmed deploy. Re-trigger the dry run. Tell the user:
"I've deployed this project before, but your deploy configuration has changed since the last time. That could mean a new platform, a different workflow, or updated URLs. I'm going to do a quick dry run to make sure I still understand how your project deploys."
Then proceed to the FIRST_RUN flow below (steps 1.5a through 1.5e).
If FIRST_RUN: This is the first time /land-and-deploy is running for this project. Before doing anything irreversible, show the user exactly what will happen. This is a dry run — explain, validate, and confirm.
Tell the user:
"This is the first time I'm deploying this project, so I'm going to do a dry run first.
Here's what that means: I'll detect your deploy infrastructure, test that my commands actually work, and show you exactly what will happen — step by step — before I touch anything. Deploys are irreversible once they hit production, so I want to earn your trust before I start merging.
Let me take a look at your setup."
Run the deploy configuration bootstrap to detect the platform and settings:
# Check for persisted deploy config in CLAUDE.md
DEPLOY_CONFIG=$(grep -A 20 "## Deploy Configuration" CLAUDE.md 2>/dev/null || echo "NO_CONFIG")
echo "$DEPLOY_CONFIG"

doneIf PERSISTED_PLATFORM and PERSISTED_URL were found in CLAUDE.md, use them directly and skip manual detection. If no persisted config exists, use the auto-detected platform to guide deploy verification. If nothing is detected, ask the user via AskUserQuestion in the decision tree below.
If you want to persist deploy settings for future runs, suggest the user run /setup-deploy.
Parse the output and record: the detected platform, production URL, deploy workflow (if any), and any persisted config from CLAUDE.md.
Test each detected command to verify the detection is accurate. Build a validation table:

# Test production URL reachability
# curl -sf {production-url} -o /dev/null -w "%{http_code}" 2>/dev/nullRun whichever commands are relevant based on the detected platform. Build the results into this table:

╚══════════════════════════════════════════════════════════╝Validation failures are WARNINGs, not BLOCKERs (except gh auth status which already failed at Step 1). If curl fails, note "I couldn't reach that URL — might be a network issue, VPN requirement, or incorrect address. I'll still be able to deploy, but I won't be able to verify the site is healthy afterward." If platform CLI is not installed, note "The {platform} CLI isn't installed on this machine. I can still deploy through GitHub, but I'll use HTTP health checks instead of the platform CLI to verify the deploy worked."
Check for staging environments in this order:

donegh pr checks --json name,targetUrl 2>/dev/null | head -20Look for check names containing "vercel", "netlify", or "preview" and extract the target URL.
Record any staging targets found. These will be offered in Step 5.
Tell the user: "Before I merge any PR, I run a series of readiness checks — code reviews, tests, documentation, PR accuracy. Let me show you what that looks like for this project."
Preview the readiness checks that will run at Step 3.5 (without re-running tests):
true # vibe-review-read 2>/dev/nullShow a summary of review status: which reviews have been run, how stale they are. Also check if CHANGELOG.md and VERSION have been updated.
Explain in plain English: "When I merge, I'll check: has the code been reviewed recently? Do the tests pass? Is the CHANGELOG updated? Is the PR description accurate? If anything looks off, I'll flag it before merging."
Tell the user: "That's everything I detected. Take a look at the table above — does this match how your project actually deploys?"
Present the full dry-run results to the user via AskUserQuestion:
If A: Tell the user: "Great — I've saved this configuration. Next time you run /land-and-deploy, I'll skip the dry run and go straight to readiness checks. If your deploy setup changes (new platform, different workflows, updated URLs), I'll automatically re-run the dry run to make sure I still have it right."
Save the deploy config fingerprint so we can detect future changes:
mkdir -p ~/.vibestack/projects/$SLUG
CURRENT_HASH=$(sed -n '/## Deploy Configuration/,/^## /p' CLAUDE.md 2>/dev/null | shasum -a 256 | cut -d' ' -f1)

echo "${CURRENT_HASH}-${WORKFLOW_HASH}" > ~/.vibestack/projects/$SLUG/land-deploy-confirmedContinue to Step 2.
If B: STOP. "Tell me what's different about your setup and I'll adjust. You can also run /setup-deploy to walk through the full configuration."
If C: STOP. "Running /setup-deploy will walk through your deploy platform, production URL, and health checks in detail. It saves everything to CLAUDE.md so I'll know exactly what to do next time. Run /land-and-deploy again when that's done."
Tell the user: "Checking CI status and merge readiness..."
Check CI status and merge readiness:
gh pr checks --json name,state,status,conclusionParse the output:
Also check for merge conflicts:
gh pr view --json mergeable -q .mergeableIf CONFLICTING: STOP. "This PR has merge conflicts with the base branch. Resolve the conflicts and push, then run /land-and-deploy again."
If required checks are still pending, wait for them to complete. Use a timeout of 15 minutes:
gh pr checks --watch --fail-fastRecord the CI wait time for the deploy report.
If CI passes within the timeout: Tell the user "CI passed after {duration}. Moving to readiness checks." Continue to Step 4. If CI fails: STOP. "CI failed. Here's what broke: {failures}. This needs to pass before I can merge." If timeout (15 min): STOP. "CI has been running for over 15 minutes — that's unusual. Check the GitHub Actions tab to see if something is stuck."
Before gathering readiness evidence, verify that the VERSION this PR claims is still the next free slot. A sibling workspace may have shipped and landed since /ship ran, leaving this PR's VERSION stale.

OFFLINE=true or the util fails: print ⚠ VERSION drift check unavailable (util offline) — proceeding with PR version v<BRANCH_VERSION>. Continue to Step 3.5. CI's version-gate job is the backstop.BRANCH_VERSION is already >= than NEXT_SLOT: no drift (or our PR is ahead of the queue). Continue.BRANCH_VERSION < NEXT_SLOT): STOP and print exactly: ⚠ VERSION drift detected.
This PR claims: v<BRANCH_VERSION>
Next free slot: v<NEXT_SLOT> (queue moved since last /ship)
Rerun /ship from the feature branch to reconcile. /ship's ALREADY_BUMPED
branch will detect the drift and rewrite VERSION + CHANGELOG header + PR title
atomically. Do NOT merge from here — the landed PR would overwrite the other
branch's CHANGELOG entry or land with a duplicate version header.Exit non-zero. Do NOT auto-bump from /land-and-deploy — rerunning /ship is the clean path (it already handles VERSION + package.json + CHANGELOG header + PR title atomically via Step 12 ALREADY_BUMPED detection).
This is the critical safety check before an irreversible merge. The merge cannot be undone without a revert commit. Gather ALL evidence, build a readiness report, and get explicit user confirmation before proceeding.
Tell the user: "CI is green. Now I'm running readiness checks — this is the last gate before I merge. I'm checking code reviews, test results, documentation, and PR accuracy. Once you see the readiness report and approve, the merge is final."
Collect evidence for each check below. Track warnings (yellow) and blockers (red).

Critical check: Look at what changed AFTER the last review. Run:
git log --oneline STORED_COMMIT..HEADIf any commits after the review contain words like "fix", "refactor", "rewrite", "overhaul", or touch more than 5 files — flag as STALE (significant changes since review). The review was done on different code than what's about to merge.
Also check for adversarial review (`codex-review`). If codex-review has been run and is CURRENT, mention it in the readiness report as an extra confidence signal. If not run, note as informational (not a blocker): "No adversarial review on record."
We are extra careful about deploys. If engineering review is STALE (4+ commits since) or NOT RUN, offer to run a quick review inline before proceeding.
Use AskUserQuestion:
review experience. Choose C only if you're confident in the code.
/review first — deeper analysis, more thorough (Completeness: 10/10)If A (quick checklist): Tell the user: "Running the review checklist against your diff now..."

Auto-fix trivial issues (whitespace, imports). For critical findings (SQL safety, race conditions, security), ask the user.
If any code changes are made during the quick review: Commit the fixes, then STOP and tell the user: "I found and fixed a few issues during the review. The fixes are committed — run /land-and-deploy again to pick them up and continue where we left off."
If no issues found: Tell the user: "Review checklist passed — no issues found in the diff."
If B: STOP. "Good call — run /review for a thorough pre-landing review. When that's done, run /land-and-deploy again and I'll pick up right where we left off."
If C: Tell the user: "Understood — skipping review. You know this code best." Continue. Log the user's choice to skip review.
If review is CURRENT: Skip this sub-step entirely — no question asked.

Choose C only if the user understands the risks.
If the user chooses B: STOP. Give specific next steps:
/review or /autoplan to review the current code, then /land-and-deploy again."/document-release to update CHANGELOG and docs."If the user chooses A or C: Tell the user "Merging now." Continue to Step 4.
Record the start timestamp for timing data. Also record which merge path is taken (auto-merge vs direct) for the deploy report.
Try auto-merge first (respects repo merge settings and merge queues):
gh pr merge --auto --delete-branchIf --auto succeeds: record MERGE_PATH=auto. This means the repo has auto-merge enabled and may use merge queues.
If --auto is not available (repo doesn't have auto-merge enabled), merge directly:
gh pr merge --squash --delete-branchIf direct merge succeeds: record MERGE_PATH=direct. Tell the user: "PR merged successfully. The branch has been cleaned up."
If the merge fails with a permission error: STOP. "I don't have permission to merge this PR. You'll need a maintainer to merge it, or check your repo's branch protection rules."
On any other non-zero exit from gh pr merge, do NOT retry the command — go to §4a-postfail to read authoritative PR state first.
Universal invariant: after ANY non-zero exit from gh pr merge, query authoritative PR state before retrying or stopping. Do NOT retry gh pr merge. Related: cli/cli#3442, cli/cli#13380.
gh pr view --json state,mergeCommit,mergedAt,mergedByIf `state == "MERGED"`:
The server-side merge succeeded (possibly completed before the local cleanup phase failed, or a concurrent merge landed). Tell the user: "PR is merged on GitHub." (Do NOT say "the merge succeeded" — this handles the concurrent-merge case.)
Capture merge SHA:
gh pr view --json mergeCommit -q .mergeCommit.oidWorktree cleanup — non-destructive, candidate-based:
git worktree list --porcelainIdentify candidates: a worktree is stale if (a) it is checked out on the base branch, AND (b) it is not the user's current main working tree, AND (c) git status --porcelain inside it is empty (no uncommitted work).
<path> checked out on <branch> with no uncommitted work. Remove it?" Remove only if user confirms (git worktree remove <path> && git worktree prune).--force. Do NOT remove the user's primary working tree.Record MERGE_PATH=direct, then continue to §4a (merge queue / CI auto-deploy detection).
If `state == "OPEN"`:
Check whether auto-merge is enabled:
gh pr view --json autoMergeRequest -q .autoMergeRequestgh pr merge stderr AND the current PR open state — then STOP.If `state == "CLOSED"`: PR was closed without merging. STOP.
Hard rule: never call `gh pr merge` a second time after a non-zero exit. Server state is authoritative.
If MERGE_PATH=auto and the PR state does not immediately become MERGED, the PR is in a merge queue. Tell the user:
"Your repo uses a merge queue — that means GitHub will run CI one more time on the final merge commit before it actually merges. This is a good thing (it catches last-minute conflicts), but it means we wait. I'll keep checking until it goes through."
Poll for the PR to actually merge:
gh pr view --json state -q .statePoll every 30 seconds, up to 30 minutes. Show a progress message every 2 minutes: "Still in the merge queue... ({X}m so far)"
If the PR state changes to MERGED: capture the merge commit SHA. Tell the user: "Merge queue finished — PR is merged. Took {duration}."
If the PR is removed from the queue (state goes back to OPEN): STOP. "The PR was removed from the merge queue — this usually means a CI check failed on the merge commit, or another PR in the queue caused a conflict. Check the GitHub merge queue page to see what happened." If timeout (30 min): STOP. "The merge queue has been processing for 30 minutes. Something might be stuck — check the GitHub Actions tab and the merge queue page."
After the PR is merged, check if a deploy workflow was triggered by the merge:
gh run list --branch <base> --limit 5 --json name,status,workflowName,headShaLook for runs matching the merge commit SHA. If a deploy workflow is found:
If no deploy workflow is found after merge:
If MERGE_PATH=auto and the repo uses merge queues AND a deploy workflow exists:
Record merge timestamp, duration, and merge path for the deploy report.
Determine what kind of project this is and how to verify the deploy.
First, run the deploy configuration bootstrap to detect or read persisted deploy settings:
# Check for persisted deploy config in CLAUDE.md
DEPLOY_CONFIG=$(grep -A 20 "## Deploy Configuration" CLAUDE.md 2>/dev/null || echo "NO_CONFIG")
echo "$DEPLOY_CONFIG"
# If config exists, parse it

doneIf PERSISTED_PLATFORM and PERSISTED_URL were found in CLAUDE.md, use them directly and skip manual detection. If no persisted config exists, use the auto-detected platform to guide deploy verification. If nothing is detected, ask the user via AskUserQuestion in the decision tree below.
If you want to persist deploy settings for future runs, suggest the user run /setup-deploy.
Classify the changes using git diff:
# diff-scope not available — classify changes manually
echo "FRONTEND=$SCOPE_FRONTEND BACKEND=$SCOPE_BACKEND DOCS=$SCOPE_DOCS CONFIG=$SCOPE_CONFIG"Decision tree (evaluate in order):
gh run list --branch <base> --limit 5 --json name,status,conclusion,headSha,workflowNameLook for workflow names containing "deploy", "release", "production", or "cd". If found: poll the deploy workflow in Step 6, then run canary.
If staging was detected in Step 1.5c (or from CLAUDE.md deploy config), and the changes include code (not docs-only), offer the staging-first option:
Use AskUserQuestion:
If A (staging first): Tell the user: "Deploying to staging first. I'll run the same health checks I'd run on production — if staging looks good, I'll move on to production automatically."
Run Steps 6-7 against the staging target first. Use the staging URL or staging workflow for deploy verification and canary checks. After staging passes, tell the user: "Staging is healthy — your changes are working. Now deploying to production." Then run Steps 6-7 again against the production target.
If B (skip staging): Tell the user: "Skipping staging — going straight to production." Proceed with production deployment as normal.
If C (staging only): Tell the user: "Deploying to staging only. I'll verify it works and stop there."
Run Steps 6-7 against the staging target. After verification, print the deploy report (Step 9) with verdict "STAGING VERIFIED — production deploy pending." Then tell the user: "Staging looks good. When you're ready for production, run /land-and-deploy again." STOP. The user can re-run /land-and-deploy later for production.
If no staging detected: Skip this sub-step entirely. No question asked.
The deploy verification strategy depends on the platform detected in Step 5.
If a deploy workflow was detected, find the run triggered by the merge commit:
gh run list --branch <base> --limit 10 --json databaseId,headSha,status,conclusion,name,workflowNameMatch by the merge commit SHA (captured in Step 4). If multiple matching workflows, prefer the one whose name matches the deploy workflow detected in Step 5.
Poll every 30 seconds:
gh run view <run-id> --json status,conclusionIf a deploy status command was configured in CLAUDE.md (e.g., fly status --app myapp), use it instead of or in addition to GitHub Actions polling.
Fly.io: After merge, Fly deploys via GitHub Actions or fly deploy. Check with:
fly status --app {app} 2>/dev/nullLook for Machines status showing started and recent deployment timestamp.
Render: Render auto-deploys on push to the connected branch. Check by polling the production URL until it responds:
curl -sf {production-url} -o /dev/null -w "%{http_code}" 2>/dev/nullRender deploys typically take 2-5 minutes. Poll every 30 seconds.
Heroku: Check latest release:
heroku releases --app {app} -n 1 2>/dev/nullVercel and Netlify deploy automatically on merge. No explicit deploy trigger needed. Wait 60 seconds for the deploy to propagate, then proceed directly to canary verification in Step 7.
If CLAUDE.md has a custom deploy status command in the "Custom deploy hooks" section, run that command and check its exit code.
Record deploy start time. Show progress every 2 minutes: "Deploy is still running... ({X}m so far). This is normal for most platforms."
If deploy succeeds (conclusion is success or health check passes): Tell the user "Deploy finished successfully. Took {duration}. Now I'll verify the site is healthy." Record deploy duration, continue to Step 7.
If deploy fails (conclusion is failure): use AskUserQuestion:
If timeout (20 min): "The deploy has been running for 20 minutes, which is longer than most deploys take. The site might still be deploying, or something might be stuck." Ask whether to continue waiting or skip verification.
Tell the user: "Deploy is done. Now I'm going to check the live site to make sure everything looks good — loading the page, checking for errors, and measuring performance."
Use the diff-scope classification from Step 5 to determine canary depth:
| Diff Scope | Canary Depth |
|---|---|
| SCOPE_DOCS only | Already skipped in Step 5 |
| SCOPE_CONFIG only | Smoke: $B goto + verify 200 status |
| SCOPE_BACKEND only | Console errors + perf check |
| SCOPE_FRONTEND (any) | Full: console + perf + screenshot |
| Mixed scopes | Full canary |
Full canary sequence:
$B goto <url>Check that the page loaded successfully (200, not an error page).
$B console --errorsCheck for critical console errors: lines containing Error, Uncaught, Failed to load, TypeError, ReferenceError. Ignore warnings.
$B perfCheck that page load time is under 10 seconds.
$B textVerify the page has content (not blank, not a generic error page).
$B snapshot -i -a -o ".vibestack/deploy-reports/post-deploy.png"Take an annotated screenshot as evidence.
Health assessment:
If all pass: Tell the user "Site is healthy. Page loaded in {X}s, no console errors, content looks good. Screenshot saved to {path}." Mark as HEALTHY, continue to Step 9.
If any fail: show the evidence (screenshot path, console errors, perf numbers). Use AskUserQuestion:
If the user chose to revert at any point:
Tell the user: "Reverting the merge now. This will create a new commit that undoes all the changes from this PR. The previous version of your site will be restored once the revert deploys."
git fetch origin <base>
git checkout <base>
git revert <merge-commit-sha> --no-edit
git push origin <base>If the revert has conflicts: "The revert has merge conflicts — this can happen if other changes landed on {base} after your merge. You'll need to resolve the conflicts manually. The merge commit SHA is <sha> — run git revert <sha> to try again."
If the base branch has push protections: "This repo has branch protections, so I can't push the revert directly. I'll create a revert PR instead — merge it to roll back." Then create a revert PR: gh pr create --title 'revert: <original PR title>'
After a successful revert: Tell the user "Revert pushed to {base}. The deploy should roll back automatically once CI passes. Keep an eye on the site to confirm." Note the revert commit SHA and continue to Step 9 with status REVERTED.
