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 | $0.00268 | $0.00268 |
| Opus 5 | $0.00134 | $0.00134 |
| Sonnet 5 | $0.00054 | $0.00054 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
cotlib 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 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.

slogpackage for logging following the examples inCONTRIBUTING.md. - Validate all input and avoid logging sensitive data.
Testing
- Write tests for all new features and maintain coverage.
- Integration tests belong in
integration_test.go. - Internal tests belong in
internal/internal_test.go. - Examples go in
examples_test.go. - Run
go test -v ./...andgo test -bench .(when benchmarking) before submitting a PR.
Documentation
- Update
README.mdand other docs for significant changes. - Include examples for new functionality.
Commit Messages
- Use the format
type(scope): Brief description. - Provide a detailed explanation if necessary.
- Allowed types:

Pull Requests
- Ensure code is formatted and all tests pass.
- Provide a clear description of changes and reference related issues.
- List notable changes and any breaking changes.
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.
