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.

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 | $0.00637 |
| Opus 5 | $0.00000 | $0.00318 |
| Sonnet 5 | $0.00000 | $0.00127 |
| Haiku 4.5 | $0.00000 | $0.00064 |
Grade A, and why
prettier 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 8d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quick Start
Prettier enforces a consistent code style across your entire codebase by parsing code and re-printing it with its own rules.
npm install --save-dev --save-exact prettier
Production Patterns
Formatting on Save
Do not rely on developers remembering to run the CLI. Integrate Prettier into VSCode (formatOnSave: true) and enforce it at the repository level using Husky and lint-staged.
Architecture & Scaling
Opinionated by Design
Prettier explicitly lacks configuration options. This is a feature, not a bug. It ends bikeshedding over code style in pull requests instantly.
Error Recovery
If Prettier conflicts with ESLint (causing the code to flip back and forth on save), you MUST use eslint-config-prettier to turn off all ESLint rules that are unnecessary or might conflict with Prettier.
Security Notes
Prettier has no significant security footprint as it only transforms ASTs. Ensure you are locking the exact version in package.json to prevent arbitrary formatting changes across the team.

Why use this skill
Use this when your agent works with prettier — structured patterns beat pasted docs and prevent common hallucinations.
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.

prettier is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 637 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 2026-09-03.
