run-lint

run-lint is a skill for Claude Code, Codex from tmj-90/gaffer. It costs 56 tokens per session (408 once invoked), scanned A, original, Apache-2.0.

A code-quality check that runs the repository's existing linter or formatter and fixes the problems it finds.

In plain words
What is it for?
Run lint checks, fix reported violations in changed files, and record proof that the check passes.
Why use it?
It catches style and formatting failures before code review or submission, without weakening the project's rules.

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

run-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 6d 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

Run the linter

Run the repo's existing lint/format check, fix what it flags, and evidence a clean run. Respect the project's config files — do not loosen rules to pass.

Steps

  1. Find the lint command from the context packet's verification commands (e.g. pnpm lint, eslint ., ruff check, golangci-lint run, mvn checkstyle:check). If silent, detect from config (eslint.config.*, .ruff.toml, .golangci.yml).
  2. Run it and capture the exact command plus the result (clean, or the list of violations with file/line).
  3. Fix violations in the files the ticket touched. Prefer the project's autofix (--fix) where it exists, then resolve the rest by hand. Do not edit unrelated files.
  4. Do not disable rules or edit config to silence errors unless the ticket explicitly asks for a rule change — fix the code instead.
  5. Re-run until clean. Evidence the exact command and its clean summary, then use the record-evidence skill to record test_output (or a lint log) against the AC and submit for review.

Rules

  • Respect existing lint/format config; never relax rules to force a pass.
  • Only touch files in the ticket's scope; don't reformat the whole repo.
  • Match the repo's linter; don't add a new one.
  • Run on a branch (the create-branch skill), never a protected branch.

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.
