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 | $0.00292 | $0.00292 |
| Opus 5.5 | $0.00117 | $0.00117 |
| Sonnet 5.5 | $0.00058 | $0.00058 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
nodejs-starter CLAUDE.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 1mo 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
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

About This Repository
A minimal Node.js library and CLI starter template. Its only application code is a placeholder Fibonacci implementation in src/ — real logic is added by projects derived from it.
Gotchas
lefthook run pre-commitskips every job when nothing is staged, even ones that ignore the staged file list — pass--all-filesto run it outside an actual commit.- The pre-commit hook fixes files in place, and the run fails if any file changes. Report that failure and leave the fixes for the user to review and re-stage before committing again.
- Vitest's 100% coverage threshold applies to the whole run, not per file — a single test file can fail on source that other tests cover, so run the full suite (
pnpm vitest run). tsconfig.jsonis for type checking, tests included;tsconfig.build.jsononly builds the package duringprepack..gitignoreignores every dotfile and dotdir (.*) — a new one needs an explicit!exception there or it silently won't be tracked.
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.
