lint

A command that checks Python code for style, formatting, import order, and—when configured—type errors. It uses tools including flake8, pylint, Black, isort, and mypy.

In plain words
What is it for?
Use it to lint Python files, format code, sort imports, check type hints, and produce detailed linting reports.
Why use it?
It catches common code-quality problems and can correct formatting, so issues are found before review or deployment.

Made for: Claude Code.

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.

Origin

This is a copy

100% identical to lint — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Python Linter

Run Python code linting and formatting tools.

Purpose

This command helps you maintain code quality using Python's best linting and formatting tools.

Usage

/lint

What this command does

  1. Runs multiple linters (flake8, pylint, black, isort)
  2. Provides detailed feedback on code quality issues
  3. Auto-fixes formatting where possible
  4. Checks type hints if mypy is configured

Example Commands

Black (code formatting)

# Format all Python files
black .

# Check formatting without changing files
black --check .

# Format specific file
black src/main.py

flake8 (style guide enforcement)

# Check all Python files
flake8 .

# Check specific directory
flake8 src/

# Check with specific rules
flake8 --max-line-length=88 .

isort (import sorting)

# Sort imports in all files
isort .

# Check import sorting
isort --check-only .

# Sort imports in specific file
isort src/main.py

pylint (comprehensive linting)

# Run pylint on all files
pylint src/

# Run with specific score threshold
pylint --fail-under=8.0 src/

# Generate detailed report
pylint --output-format=html src/ > pylint_report.html

mypy (type checking)

# Check types in all files
mypy .

# Check specific module
mypy src/models.py

# Check with strict mode
mypy --strict src/

Configuration Files

Most projects benefit from configuration files:

.flake8

[flake8]
max-line-length = 88
exclude = .git,__pycache__,venv
ignore = E203,W503

pyproject.toml

[tool.black]
line-length = 88

[tool.isort]
profile = "black"

Best Practices

  • Run linters before committing code
  • Use consistent formatting across the project
  • Fix linting issues promptly
  • Configure linters to match your team's style
  • Use type hints for better code documentation

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.
