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 | $0.00000 | $0.00076 |
| Opus 5 | $0.00000 | $0.00038 |
| Sonnet 5 | $0.00000 | $0.00015 |
| Haiku 4.5 | $0.00000 | $0.00008 |
Grade A, and why
code-style 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 yesterday.
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
TypeScript And Code Style
Linting and formatting
- ESLint uses
@callstack/eslint-configtogether withtypescript-eslint. - Important enforced rules include
no-consoleand consistent type imports. - oxfmt is the formatter.
- Formatting defaults include single quotes and trailing commas.
Imports
- Keep imports sorted with
oxfmt.
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.

code-style is an agent published in the GitHub repository callstack/react-native-testing-library (3,414 stars, last pushed 19d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 76 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
