Ship prod

Ship Prod

Deploys COMMITTED HEAD only, to the correct Vercel project, then proves the deploy landed. git push to main does not reliably auto-deploy; this skill is the deploy path.

Fixed facts

• Project: qaskills.sh, project ID prj_rDKli4AyhHoXZXV8NHrs92Ncbf4f, org team_DGM6VSs6vhASlhktmHkSqPwn, account luckydutta96
• A decoy project qaskills exists WITHOUT the domain. Never deploy there. Never accept interactive "link this directory?" defaults.
• Build command lives in root vercel.json (shared build && web build); Node must stay 20.x (Neon driver breaks on 24)
• vercel --prod uploads the WORKING TREE, not git HEAD
• .vercel/project.json is gitignored, so fresh worktrees are unlinked: explicit env IDs required there

Preflight

cd /Users/promode/qaskills
vercel whoami                              # must be luckydutta96; else STOP, user must vercel login
git status --short                         # empty => clean path; anything => worktree path
git log -1 --oneline --stat | head -15     # confirm HEAD is exactly what you intend to ship
pnpm --filter @qaskills/shared build && pnpm --filter @qaskills/web build   # never ship a red build

Deploy

Clean tree (no modified or untracked files that could ship):

cd /Users/promode/qaskills && npx vercel --prod --yes

Dirty tree (default assumption; the working tree here usually carries WIP):

DEPLOY_DIR=$(mktemp -d)/qaskills-deploy
git -C /Users/promode/qaskills worktree add "$DEPLOY_DIR" HEAD
cd "$DEPLOY_DIR"
VERCEL_ORG_ID=team_DGM6VSs6vhASlhktmHkSqPwn \
VERCEL_PROJECT_ID=prj_rDKli4AyhHoXZXV8NHrs92Ncbf4f \
npx vercel --prod --yes
cd /Users/promode/qaskills
git worktree remove "$DEPLOY_DIR" --force

Capture the deployment URL the CLI prints; it goes in the final summary.

Verify (required, every deploy)

npx vercel ls | head -5                                         # newest deployment: Ready, Production
curl -s -o /dev/null -w '%{http_code}\n' https://qaskills.sh    # 200
# The specific change, visible live. Examples:
curl -s -o /dev/null -w '%{http_code}\n' https://qaskills.sh/blog/<new-slug>   # new article: 200
curl -s https://qaskills.sh/<changed-page> | grep -c '<expected-marker>'       # code change: >= 1

All three must pass before saying "deployed". If the domain still serves old content while the new deployment is Ready, the alias did not move: npx vercel promote <deployment-url>.

Rollback

npx vercel ls                       # find the previous Ready production deployment
npx vercel promote <previous-url>   # fast path: point the domain back

For a code-level revert, git revert <sha> on main, then run this skill again.

Failure modes

Symptom	Cause	Fix
CLI asks to link / offers project qaskills	Unlinked dir, interactive defaults	Abort; re-run with both VERCEL_* env vars set
Error: not authorized / wrong scope	Logged into another account	vercel whoami; user runs vercel login as luckydutta96
Vercel build fails, local build green	Env-dependent code at import time	Lazy-init pattern (see CLAUDE.md); no secrets required at build
Deploy Ready but site unchanged	Domain alias on older deployment, or you shipped stale HEAD	vercel promote; confirm intended commit was in HEAD
WIP appeared on prod	Deployed dirty working tree directly	Roll back via promote, then redeploy via worktree

Red flags

• "The push probably triggered a deploy"
• Deploying from a dirty root without the worktree
• Answering Vercel's interactive prompts with defaults
• Declaring success without the three verification commands' output
• Touching Vercel project settings (Node version, env vars, domains) without user approval
