What is openapi-mcp javascript.instructions.md?

A set of JavaScript coding rules covering formatting, module syntax, comments, and basic code quality. It requires Japanese JSDoc comments for functions, methods, and classes.

Writing or reviewing JavaScript with 120-character lines, single quotes, semicolons, spaces for indentation, ES modules, and Prettier-compatible formatting.

It gives JavaScript projects consistent standards for formatting and structure, and helps prevent unused code and invalid syntax.

Token cost

What it costs to keep this loaded

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	$0.00586	$0.00586
Opus 5.5	$0.00234	$0.00234
Sonnet 5.5	$0.00117	$0.00117
Haiku 4.5	$0.00059	$0.00059

Security

Grade A, and why

openapi-mcp javascript.instructions.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 2mo 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.
