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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 5.1 | $0.00000 | $0.00676 |
| Opus 5.5 | $0.00000 | $0.00270 |
| Sonnet 5.5 | $0.00000 | $0.00135 |
| Haiku 4.5 | $0.00000 | $0.00068 |
Grade A, and why
biome 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.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quick Start
Biome is a high-performance toolchain written in Rust that completely replaces ESLint and Prettier. It formats and lints code in milliseconds.
npm install --save-dev --save-exact @biomejs/biome
npx @biomejs/biome init
Production Patterns
CI Pipeline Integration
Replace slow npm run lint and npm run format:check steps in your GitHub Actions with npx @biomejs/biome ci .. It runs both formatting and linting concurrently in a fraction of a second.
Architecture & Scaling
Rust Native
Because Biome is a compiled Rust binary, it completely bypasses the V8 Node.js runtime overhead, resulting in 35x faster execution times compared to standard JS-based tooling.
Error Recovery
If Biome conflicts with your IDE's built-in TypeScript formatter, ensure you have the official Biome extension installed and set it as the default formatter in .vscode/settings.json.
Security Notes
Biome does not execute third-party plugins (unlike ESLint). This eliminates the supply chain attack vector of malicious linting rules stealing environment variables during the build process.
What ships with it
2 files 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.

biome is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 676 tokens. 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 2026-08-30.
