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 | $0.00940 | $0.00940 |
| Opus 5.5 | $0.00376 | $0.00376 |
| Sonnet 5.5 | $0.00188 | $0.00188 |
| Haiku 4.5 | $0.00094 | $0.00094 |
Grade A, and why
react-svg 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 26d 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.
How it starts
The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Rules for coding agents that the code and config don't already state. Keep it that way: a constraint that can live in a comment next to the thing it constrains belongs there, not here.
Writing
- NZ English everywhere ("colour", "behaviour", "initialise").
- Commit subjects and PR titles are one plain capitalised sentence,
git log --onelinestyle, with no conventional-commit prefix (feat:,fix:,chore(deps):). Nothing reads a prefix: the version bump comes from the PR label. - Add a commit body whenever the change had a reason the diff does not show: what it fixes, what it rules out, what constraint forced the shape it has. Hard-wrap it at 72 columns.
- PR titles are copied verbatim into the generated release notes, so write them as the changelog line you want readers to see.
- Do not hard-wrap markdown files, PR descriptions or issue descriptions.
Build & test
npm run test:srcis the development loop.npm testis the full gate and takes minutes: it installs and runs every React version undertest/react/.npm run size,test:cjs,test:es,test:distand thepackage:*checks readdist/, so they need a currentnpm run build.- Raising a
size-limitbudget inpackage.jsonis a decision, not a fix. Find what grew first, and say why in the commit message. test/manual/is a hand-driven screen-reader harness, outsidenpm testand CI. When you change the ARIA wiring or theloadingelement's lifecycle, run it astest/manual/README.mddescribes, record the result in the PR, and update that README's recorded runs in the same commit.test/react/covers boundary versions only: the first and last minor of each supported major, plus minors that changed behaviour. For the current major the rootdevDependenciescover the newest minor, so the matrix holds only its first minor; add its last minor when the next major ships. Copy a siblingpackage.json, and seescripts/test-react.tsfor how a single version is run.
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.
