Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00025 | $0.00378 |
| Opus 5 | $0.00013 | $0.00189 |
| Sonnet 5 | $0.00005 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
scaffold-nestjs-api 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 5d 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 API
Project name: $ARGUMENTS (default to "my-nestjs-api" if not provided)
Delegate to the nestjs-api skill for all patterns, templates, and reference files.
Steps
- Create
.gitignorefirst — before any other file. Include:node_modules/,.env,*.pem,*.key,dist/,coverage/,.turbo/,.DS_Store - Read the
nestjs-apiskill and its reference files for exact code templates - Create NestJS project —
npx @nestjs/cli new <name> --package-manager npm --strict --skip-git - Install dependencies (Fastify adapter, Prisma, config, swagger, terminus, throttler, validators, helmet) per skill conventions
- Replace Jest with Vitest (remove jest packages, add vitest + @swc/core + unplugin-swc)
- Replace Express with Fastify adapter in
src/main.ts - Set up directory structure, config, Prisma 7.x (driver adapter pattern), and modules using skill reference templates
- Add global exception filter (RFC 9457), validation pipe, logging interceptor, health module, and security middleware
- Add infrastructure (Dockerfile, docker-compose.dev.yml, .env via Bash)
- Run
npm audit --audit-level=high— fix or document any critical/high CVEs before proceeding - Verify —
npx tsc --noEmit
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-api is a command published in the GitHub repository kumaran-is/claude-code-onboarding (35 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 378 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
