What is code-style-javascript?

A style guide for JavaScript and TypeScript code, covering imports, names, file names, comments, formatting, ESLint, and Prettier.

Use it when creating or reviewing JavaScript or TypeScript files, especially imports, naming, comments, and line length.

It reduces inconsistent code and makes project files easier to read and maintain.

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.

Clone the repo

git clone --depth 1 https://github.com/diegomarino/awesomic-cursor-rules

Per session 0 Nothing until a file matches its globs; then the whole rule loads.

When invoked 251 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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	$0.00000	$0.00251
Opus 5	$0.00000	$0.00125
Sonnet 5	$0.00000	$0.00050
Haiku 4.5	$0.00000	$0.00025

Security

Grade A, and why

code-style-javascript 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.

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.
