lint

A project command that checks and formats source code using the linter and formatting tools configured in the repository.

In plain words
What is it for?
Use it to check all or changed files, fix lint problems, format code, or process one specified file.
Why use it?
It catches style and code-quality problems before they reach a commit or continuous integration (CI), the automated checks that run for changes. It can also fix supported issues automatically.

Made for: Claude Code.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 256 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 and format code: $ARGUMENTS

Instructions

Uses {{LINTER}} for linting/formatting. Config: {{LINTER_CONFIG_FILE}} at repo root. Style: {{STYLE_RULES}}

Determine scope from arguments:

Argument Action
check or all {{LINT_CHECK_CMD}} (report only)
fix or write {{LINT_FIX_CMD}} (auto-fix)
format {{FORMAT_CMD}} (format only)
<file-path> {{LINT_FIX_CMD}} <file-path> (single file)
changed Lint only files changed vs main

Common workflows:

  1. Before commit: {{LINT_FIX_CMD}} <changed-files>
  2. CI equivalent: {{LINT_CHECK_CMD}}

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.
