node-typescript-boilerplate is a starter repository for Node.js projects written in TypeScript, with configurations and tools for modules, testing, linting, formatting, continuous integration, and local tool versions. Developers use it as a foundation for backend services, command-line tools, workers, APIs, and libraries. Its catalogue instructions guide coding agents working in projects based on the template.

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 | $0.00064 | $0.00064 |
| Opus 5.5 | $0.00026 | $0.00026 |
| Sonnet 5.5 | $0.00013 | $0.00013 |
| Haiku 4.5 | $0.00006 | $0.00006 |
Grade A, and why
node-typescript-boilerplate AGENTS.md 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
AGENTS.md
- Follow the repository's existing conventions, configuration, runtime, package manager, and tooling. Do not introduce alternatives without a justified reason.
- Preserve type safety. Do not introduce
any, unsafe assertions, or suppress TypeScript/lint errors just to bypass problems. Narrowly justify necessary exceptions.
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.
