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.

Security

Grade A, and why

deploy-vercel scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Deploy on Vercel

Overview

Ship this project to Vercel with correct env vars, build settings, and production checks. Applies to Next.js App Router and Express API boilerplates in this catalog.

Pre-deploy Checklist

  • npm run build passes locally
  • npm test passes
  • Secrets are in Vercel project settings, not in git
  • No debug logging of tokens or PII
  • Production URL and env documented in README

Next.js App Router

  1. Connect the Git repo in the Vercel dashboard (or vercel link + vercel deploy).
  2. Framework preset: Next.js (auto-detected).
  3. Set server-only env vars in Vercel — never prefix secrets with NEXT_PUBLIC_.
  4. Use Server Components and Route Handlers for privileged logic.
  5. After deploy, smoke-test critical routes and API handlers.

Common issues:

  • Build fails on server/client boundary — find "use client" leaks of server modules.
  • Missing env at build time — set vars for Production and Preview if needed.

Express API (serverless)

  1. This boilerplate ships vercel.json routing to the Express app.
  2. Set NODE_ENV=production and API secrets in Vercel env settings.
  3. Keep handlers stateless — no in-memory session stores across invocations.
  4. Run integration tests against vercel dev before promoting to production.

Common issues:

  • Cold starts — keep startup lean; lazy-load heavy deps.
  • Body size / timeout — respect Vercel function limits; return 413/504 gracefully.

Environment Variables

Kind Where
Secrets (API keys, DB URLs) Vercel → Settings → Environment Variables (Production)
Public config (analytics ID) NEXT_PUBLIC_* only when safe for browsers
Local dev .env.local (gitignored) — never commit

Post-deploy

  1. Hit health or home route; confirm expected status.
  2. Check Vercel function logs for startup errors.
  3. Run bwai scan-project on the deployed repo clone if skills changed.

Rollback

Use Vercel instant rollback to the previous production deployment if smoke tests fail. Fix forward only after identifying root cause.

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.
