javascript-typescript-code-style

A set of coding rules for JavaScript and TypeScript, including modern language features, functional programming patterns, and clear names.

In plain words
What is it for?
Guiding how JavaScript and TypeScript files are written, especially variable naming, class usage, and functional code patterns.
Why use it?
It gives code written in these languages a consistent style that is easier to read and maintain.

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.

Security

Grade A, and why

javascript-typescript-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.

Origin

This is a copy

100% identical to javascript-typescript-code-style — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says


description: Rules for JavaScript and TypeScript code style, including modern features, functional patterns, and descriptive naming conventions. globs: **/*.{js,ts}

  • Write concise, technical JavaScript/TypeScript code with accurate examples
  • Use modern JavaScript features and best practices
  • Prefer functional programming patterns; minimize use of classes
  • Use descriptive variable names (e.g., isExtensionEnabled, hasPermission)

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.
