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 | $0.00100 | $0.00472 |
| Opus 5 | $0.00050 | $0.00236 |
| Sonnet 5 | $0.00020 | $0.00094 |
| Haiku 4.5 | $0.00010 | $0.00047 |
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 10d 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:
- Confirm parameters:
project_name,project_slug(kebab-case),db_name,api_port, ORM choice (default Prisma), include flags for BullMQ / auth / OTel. - Read
backend/nestjs/PROMPT.md— full directory tree, deps, key files (package.json, env schema, app.module, prisma service, users module). - Read deep-dives as needed:
01-project-layout.md— module structure, DI, when to use repositories02-prisma-and-migrations.md— schema design, migrations03-validation-and-dtos.md— class-validator + class-transformer04-auth-jwt-passport.md(if include_auth) — global guards, RBAC05-bullmq-queues.md(if include_bullmq)06-testing-jest-supertest.md
- Generate: scaffold tree,
package.jsonwith 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. - Verify:
pnpm install,pnpm prisma generate && pnpm prisma migrate dev --name init,pnpm test,pnpm lint— clean. - 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.
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.

scaffold-nestjs is a skill published in the GitHub repository arunanksharan/claude-forge (2 stars, last pushed 4mo ago), licensed Unlicense.
