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.

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 | $0.00008 | $0.00335 |
| Opus 5 | $0.00004 | $0.00168 |
| Sonnet 5 | $0.00002 | $0.00067 |
| Haiku 4.5 | $0.00001 | $0.00034 |
Grade A, and why
Cursor rules for ES Module development with Node 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 11d 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.

When to use this skill
Cursor rules for ES Module development with Node.js guidelines.
Source
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
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
