linters

linters is a skill for Claude Code, Codex from luisalima/agent-policy-kit. It costs 54 tokens per session (544 once invoked), scanned A, original, MIT.

A skill for adding or improving linters, which are automated checks that find common code problems and style issues. It first examines the repository's existing languages, tools, and commands.

In plain words
What is it for?
Use it to add lint commands or CI checks for JavaScript, TypeScript, Python, Go, Rust, Ruby, or shell code, while fitting the project's current setup.
Why use it?
It prevents projects from accumulating inconsistent or unnecessary checks and helps catch problems before code is merged or released.

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

linters 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 5d 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.

Linters

Add or improve static checks that match the repository's languages, package managers, and existing conventions.

Workflow

  1. Inspect the project before choosing tools:
    • Existing scripts: package.json, pyproject.toml, Cargo.toml, go.mod, Makefile, CI files, pre-commit config.
    • Existing formatters, test commands, and dependency managers.
    • Languages touched by the current task.
  2. Prefer existing tooling:
    • If a lint command exists, run it and improve configuration only when needed.
    • If a nearby package/module already has a linter, mirror that pattern.
  3. Add the smallest relevant lint setup:
    • JavaScript/TypeScript: ESLint or the repo's existing framework lint command.
    • Python: Ruff by default, unless the repo already uses Flake8, Pylint, Black, or mypy.
    • Go: gofmt/go vet, and golangci-lint only when the repo already expects it or asks for it.
    • Rust: cargo fmt and cargo clippy.
    • Ruby: RuboCop when the repo uses Bundler/Ruby conventions.
    • Shell: ShellCheck when shell scripts are part of the repo.
  4. Wire the linter into the project:
    • Add or update a lint script, Make target, task runner entry, or CI step that matches existing conventions.
    • Document the command in AGENTS.md only if agents need to run it regularly.
  5. Verify:
    • Run the new or updated lint command.
    • Fix reported issues only when in scope.
    • If lint failures are pre-existing and broad, report them and avoid mixing a large cleanup into unrelated work.

Rules

  • Do not add a linter just because one exists for the language. Add it when it protects changed code or a missing project check.
  • Do not introduce a new package manager or build system for linting.
  • Do not replace an established linter without an explicit reason.
  • Do not weaken lint rules to make the current change pass unless the rule is clearly wrong for the project.
  • Keep formatter and linter responsibilities separate unless the chosen tool intentionally covers both.
  • Prefer a focused follow-up task over broad lint cleanup when failures are unrelated.

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.
