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

scaffold-nestjs 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 2mo 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.

What it actually says

Scaffold NestJS Project (claudeforge)

Follow the master prompt at backend/nestjs/PROMPT.md. Steps:

  1. Confirm parameters: project_name, project_slug (kebab-case), db_name, api_port, ORM choice (default Prisma), include flags for BullMQ / auth / OTel.
  2. Read backend/nestjs/PROMPT.md — full directory tree, deps, key files (package.json, env schema, app.module, prisma service, users module).
  3. Read deep-dives as needed:
    • 01-project-layout.md — module structure, DI, when to use repositories
    • 02-prisma-and-migrations.md — schema design, migrations
    • 03-validation-and-dtos.md — class-validator + class-transformer
    • 04-auth-jwt-passport.md (if include_auth) — global guards, RBAC
    • 05-bullmq-queues.md (if include_bullmq)
    • 06-testing-jest-supertest.md
  4. Generate: scaffold tree, package.json with locked deps, prisma schema with one example model, Users feature module (controller/service/dto/entity), AuthModule with global JwtAuthGuard + @Public() opt-out, HealthModule via terminus, queue module if requested.
  5. Verify: pnpm install, pnpm prisma generate && pnpm prisma migrate dev --name init, pnpm test, pnpm lint — clean.
  6. Hand off: setup steps for the user.

Use Prisma unless the user picked Drizzle/TypeORM. Skip the repository layer for simple CRUD with Prisma; document why.

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.
