es-module-nodejs-guidelines-cursorrules-prompt-fil

A set of coding rules for Node.js projects that use ES modules, JavaScript's standard module system. It covers code structure, current Node.js features, comments, and response style.

In plain words
What is it for?
Use it when creating or reviewing ES module code, planning implementation steps, suggesting refactors, documenting unclear operations, and controlling answer length with V0–V3 settings.
Why use it?
It gives consistent guidance for building modular, maintainable, readable, and secure Node.js code instead of making those choices repeatedly.

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.

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

es-module-nodejs-guidelines-cursorrules-prompt-fil 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.

What it actually says

General

  • Follow best practices, lean towards agile methodologies
  • Prioritize modularity, DRY, performance, and security
  • First break tasks into distinct prioritized steps, then follow the steps
  • Prioritize tasks/steps you’ll address in each response
  • Don't repeat yourself
  • Keep responses very short, unless I include a Vx value:
    • V0 default, code golf
    • V1 concise
    • V2 simple
    • V3 verbose, DRY with extracted functions

Code

  • Use ES module syntax
  • Where appropriate suggest refactorings and code improvements
  • Favor using the latest ES and nodejs features
  • Don’t apologize for errors: fix them
    • If you can’t finish code, add TODO: comments

Comments

  • Comments should be created where the operation isn't clear from the code, or where uncommon libraries are used
  • Code must start with path/filename as a one-line comment
  • Comments should describe purpose, not effect
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.
