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 5.1 | $0.00225 | $0.00225 |
| Opus 5.5 | $0.00090 | $0.00090 |
| Sonnet 5.5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
typescript-coding-rule 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
Common
- Use English for all comments
Comments and documentation
JSDoc tags
It allows a subset of JSDoc tags. Most tags must occupy their own line, with the tag at the beginning of the line.
/**
* The "param" tag must occupy its own line and may not be combined.
* @param left A description of the left param.
* @param right A description of the right param.
*/
function add(left: number, right: number) { ... }
Document all top-level exports of modules
Use /** JSDoc */ comments to communicate information to the users of your code. Avoid merely restating the property or parameter name. You should also document all properties and methods (exported/public or not) whose purpose is not immediately obvious from their name, as judged by your reviewer.
Exception: Symbols that are only exported to be consumed by tooling, such as @NgModule classes, do not require comments.
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.

typescript-coding-rule is a cursor rule published in the GitHub repository sotayamashita/openapi-mcp-server (7 stars, last pushed 2d ago), licensed MIT. It adds 225 tokens to every session, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 0 findings.
