What is deploy-check?

A pre-deployment checklist for publishing an application to staging or production. It supports Vercel, Railway, and Docker-based servers, and can check database migrations and access rules.

It runs checks for TypeScript, linting, tests, environment variables, debug logging, migrations, and row-level security. It can also deploy to the selected platform and run a basic check after deployment.

It catches code, test, configuration, secret, migration, and database-security problems before they reach users.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.00536
Opus 5	$0.00015	$0.00268
Sonnet 5	$0.00006	$0.00107
Haiku 4.5	$0.00003	$0.00054

Security

Grade A, and why

deploy-check scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What it actually says

Arguments

env : staging | production

Étape 1 — Pre-deploy checks (script unifié)

python scripts/pre_deploy_check.py --env [staging|production]

Couvre : TypeScript, lint, tests, secrets, .env.example, console.log, migrations, RLS. Bloquer si exit 1.

Étape 2 — Plateforme de déploiement

Vercel (recommandé SaaS Next.js)

vercel --env staging      # Preview URL
vercel --prod             # Production

Variables requises dans Vercel : DATABASE_URL (pooler port 6543), DIRECT_URL (port 5432), NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY.

Railway

railway up --environment staging
railway up --environment production

Docker / VPS (Coolify, Dokku)

docker build -t app:$(git rev-parse --short HEAD) .
docker push [registry]/app:[tag]
# Puis trigger deploy via webhook ou CLI Coolify/Dokku

Étape 3 — Migrations DB (si Supabase)

python scripts/supabase_migrate.py --diff          # Voir ce qui va être appliqué
python scripts/supabase_migrate.py --env [env]     # Appliquer
python scripts/supabase_rls_check.py               # Vérifier RLS

Étape 4 — Post-deploy

Smoke test : curl https://[domain]/api/health
Logs plateforme — 0 erreur 500 dans les 2 premières minutes
Sentry — nouvelles erreurs ?
Mettre à jour .claude/memory/session.md avec la version déployée

Rollback

Vercel : vercel rollback [deployment-url] Railway : railway rollback Docker : redéployer le tag précédent DB : créer une nouvelle migration inverse (python scripts/supabase_migrate.py --new rollback-[feature])

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

deploy-check is a skill published in the GitHub repository GlamgarOnDiscord/claude-saas-blueprint (2 stars, last pushed 3mo ago), licensed MIT. It adds 30 tokens to every session and 536 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
