lint

lint is a skill for Claude Code from PMDevSolutions/Aurelius. It costs 54 tokens per session (458 once invoked), scanned A, original, MIT.

A project cleanup command that runs ESLint to find code-quality problems, Prettier to standardise formatting, and TypeScript to check types. It can fix some issues automatically or only report them.

In plain words
What is it for?
Use it to lint, format, type-check, and clean up JavaScript or TypeScript projects before sharing changes.
Why use it?
It removes the need to run several code checks by hand and shows which problems still need manual work.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is Bash(./scripts/lint-and-format.sh *), Bash(pnpm eslint *), Bash(pnpm prettier *), Bash(pnpm tsc *).

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

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.

Security

Grade A, and why

lint 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 2d 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

Lint & Format

Run ESLint and Prettier across the project.

Purpose

This command checks and fixes code quality and formatting issues using ESLint and Prettier.

Usage

/lint            # fix what can be fixed, report the rest
/lint --check    # report only, change nothing

What this command does

  1. Runs ESLint to check for code quality issues
  2. Runs Prettier to check formatting
  3. Auto-fixes where possible
  4. Reports remaining issues that need manual attention

Steps

1. Check if tools are installed

pnpm eslint --version && pnpm prettier --version

2. Run ESLint with auto-fix

pnpm eslint . --fix --ext .ts,.tsx,.js,.jsx

3. Run Prettier

pnpm prettier --write "src/**/*.{ts,tsx,js,jsx,css,json,md}"

4. Type check

pnpm tsc --noEmit

Or use the project script

./scripts/lint-and-format.sh $ARGUMENTS

With --check the script reports without changing files, as CI runs it.

Common Issues

  • Missing ESLint config: Copy templates/shared/eslint.config.js to project root
  • Missing Prettier config: Copy templates/shared/prettier.config.js to project root
  • Conflicting rules: Ensure eslint-config-prettier is installed to disable formatting rules in ESLint
Changes

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.
