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 | $0.00016 | $0.00173 |
| Opus 5.5 | $0.00006 | $0.00069 |
| Sonnet 5.5 | $0.00003 | $0.00035 |
| Haiku 4.5 | $0.00002 | $0.00017 |
Grade A, and why
javascript-code 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 1mo 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
JavaScript/TypeScript Code Skill
This skill manages JavaScript and TypeScript specific development practices across Node.js, browsers, and edge runtimes.
When to use this skill
- When writing or maintaining JS/TS applications.
- When dealing with asynchronous programming (Promises, async/await).
- When configuring module systems (ESM vs CommonJS).
Guidelines
- Prefer TypeScript over vanilla JavaScript for large projects to leverage static typing.
- Always use strict equality (
===) and avoid loose equality (==). - Avoid mutating state when possible; prefer functional approaches like
map,filter, andreduce. - Use
constby default,letwhen necessary, and never usevar.
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.

javascript-code is a skill published in the GitHub repository DongDuong2001/pudo-code-system (5 stars, last pushed 11d ago), licensed MIT. It adds 16 tokens to every session and 173 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
