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 | $0.00374 | $0.00374 |
| Opus 5 | $0.00187 | $0.00187 |
| Sonnet 5 | $0.00075 | $0.00075 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
vitest-auto-spy 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 7d 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
vitest-auto-spy — instructions for AI coding agents
Read AGENTS.md. It is the single source, and it is written for you.
This file exists only because Claude Code discovers repository instructions from CLAUDE.md and
does not read AGENTS.md. Duplicating the content here would guarantee the two copies disagree
within a release, so this one is a pointer and nothing else.
Three things worth knowing before you start, because they are the ones that cost time:
- Never commit, push or tag. The maintainer does that by hand.
npm run checkis the gate —deps:check, typecheck, lint,format:check, jscpd,llms:check,docs:check, the sync checks, coverage at 100 % oversrc/lib/**andsrc/cli/**, the type tests, the type-instantiation budget (types:budget), and the shared-env, zone, Bun and Bun-Angular suites. A change is not finished until it passes.- The landing cards in
docs-site/index.mdare prose inside YAML. A:in an unquoteddetails:ortitle:value ends the value and starts a new key, and the only thing that reads that frontmatter isvitepress build— in the pages workflow, after the gate, so it fails onmasterwith the deploy already red. Write a semicolon or a dash instead, and runnpm run docs:checkafter touching any frontmatter underdocs-site/.
Repository conventions, the public API, the error catalogue and the recipes are all in AGENTS.md.
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.
