lint

A project-wide linting command that runs the configured code-quality checks, including checks that only work across the whole project. Linting means automatically looking for code problems and style violations.

In plain words
What is it for?
Use it to run all enabled linters, limit checks to a language or named linter, or run available automatic fixes before checking the project.
Why use it?
It avoids running only a small file-level check and includes broader checks such as security, Ruby, and Rust linters when they are configured.

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 yesterday.

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.

Lint

Run configured linters across the full project. Includes whole-project-only linters (brakeman, clippy) that don't run in the PostToolUse hook.

Usage

  • /lint — Run all enabled linters on the full project
  • /lint ruby — Run only Ruby linters
  • /lint reek — Run only the reek linter
  • /lint semgrep — Run only Semgrep (tool linter)
  • /lint --fix — Run autofix on all files first, then lint

Arguments after /lint are parsed as:

  • A language name (ruby, javascript, python, go, rust, markdown, html, shell) → filter to that language
  • A linter name (rubocop, reek, eslint, ruff, etc.) → filter to that specific linter
  • A tool linter name (semgrep) → filter to that tool linter
  • --fix → run autofix commands before linting

Step 1: Load Config

PROJECT_DIR="${CLAUDE_PROJECT_DIR:-$(pwd)}"
PROJECT_HASH=$(echo "$PROJECT_DIR" | tr '/' '-' | sed 's/^-//')
CONFIG_FILE="$HOME/.claude/code-lint/$PROJECT_HASH/config.json"

If no config exists, tell the user to run /setup-lint first.

Read and parse the config JSON.

Step 2: Determine Scope

Parse arguments to determine what to run:

  • No args → all enabled languages, all enabled linters
  • Language arg → only that language's linters
  • Linter arg → only that specific linter
  • --fix → enable autofix mode

Step 3: Run Linters

For each enabled linter in scope:

Single-file linters

Find all matching files (using file_patterns), excluding paths that match exclude_patterns. Run the linter on all matching files at once (most linters accept multiple files or directories).

cd "$PROJECT_DIR"

# If --fix mode, run autofix first
bundle exec rubocop -A --fail-level=error .

# Then run the lint check
bundle exec rubocop .

Whole-project-only linters

Run these against the project root:

cd "$PROJECT_DIR"
bundle exec brakeman -q
cargo clippy -- -D warnings

Tool linters (e.g. Semgrep)

After running per-language linters, check the tool_linters section of the config. For each enabled tool linter:

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.

lint is a skill published in the GitHub repository ericboehs/claude-plugins (2 stars, last pushed 8d ago), licensed MIT. It adds 36 tokens to every session and 1,344 once invoked, about $0.0002 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 2026-08-31.
