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: 10 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 | $0.00073 | $0.01749 |
| Opus 5 | $0.00036 | $0.00874 |
| Sonnet 5 | $0.00015 | $0.00350 |
| Haiku 4.5 | $0.00007 | $0.00175 |
Grade A, and why
linting 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 10d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TypeScript Linting and Formatting
ESLint + typescript-eslint for type-aware linting, Biome as a fast all-in-one alternative, Prettier for formatting, and CI wiring.
ESLint with typescript-eslint
Setup
npm install -D eslint @eslint/js typescript typescript-eslint
ESLint 9+ uses flat config (eslint.config.js / .mjs) — a plain array of config objects, not the older .eslintrc cascading-file format. npm init @eslint/config@latest scaffolds one interactively; the shape by hand:
// eslint.config.mjs
import js from "@eslint/js";
import tseslint from "typescript-eslint";
export default tseslint.config(
js.configs.recommended,
...tseslint.configs.strict,
...tseslint.configs.stylistic,
{
rules: {
"@typescript-eslint/no-unused-vars": ["error", { argsIgnorePattern: "^_" }],
},
},
);
@eslint/js exports { meta, configs } — js.configs.recommended, not js.recommended or js.default. Running js.recommended directly fails at config-load time (Unexpected undefined config) since it resolves to undefined.
Preset selection
typescript-eslint ships three stacked preset tiers — pick a floor, don't cherry-pick individual rules out of a higher tier without understanding what the lower tier already covers:
| Preset | What it adds |
|---|---|
recommended |
Rules that catch common bugs and mistakes with minimal false positives — the floor for any TypeScript project |
strict |
A superset of recommended with more opinionated rules that catch bugs recommended deliberately leaves out to avoid false positives |
stylistic |
Consistency rules with no bug-catching intent — naming conventions, member ordering; layered on top of either of the above, never a substitute |
Default to recommended + stylistic for most projects; reach for strict when the codebase can absorb its stricter defaults (banning // @ts-ignore without a description, disallowing certain type assertions) without a large one-off migration. This mirrors the workspace's general strictness posture (/core:security, /core:tdd CI-strictness discipline) — start strict on new code, treat loosening as the exception that needs a reason.
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.
- 10d ago First seen · 167 lines · 73 tokens per session scan A 5b45d93469dc
linting is a skill published in the GitHub repository vinnie357/claude-skills (25 stars, last pushed today), licensed MIT. It adds 73 tokens to every session and 1,749 once invoked, about $0.0004 per session on Opus 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 2026-08-30.
