typescript-coding-style

A set of rules for keeping TypeScript code consistent and readable. It applies to `.ts` files and checks project settings such as ESLint, Prettier, and EditorConfig.

In plain words
What is it for?
Use it when writing or reviewing TypeScript files, especially in a project that already defines formatting and editing rules.
Why use it?
It reduces style differences and helps prevent overly long or complicated code. It also sets limits on function size, parameter count, and line length.

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

typescript-coding-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 2d 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.

Origin

This is a copy

100% identical to typescript-coding-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: Enforces code style and best practices for TypeScript files. globs: **/*.ts

  • Code should obey the rules defined in the .eslintrc.json, .prettierrc, and .editorconfig files.
  • Lines should not be more than 80 characters.
  • Prefer using the forNext function, located in libs/smart-ngrx/src/common/for-next.function.ts instead of for(let i;i < length;i++), forEach or for(x of y).
  • Functions and methods should not have more than 4 parameters.
  • Functions should not have more than 50 executable lines.

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.
