GitHub CLI
$ gh skill install Microck/ordinary-claude-skills lint --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/Microck/ordinary-claude-skills.git skills-src && mkdir -p .claude/skills && cp -r skills-src/skills_all/lint .claude/skills/lint && rm -rf skills-src

What it does

Lint is an agent skill from Microck/ordinary-claude-skills. Run targeted linting, formatting, and code quality checks on modified files. Use this to validate code style, type safety, security, and other quality metrics before committing. Supports running all checks or targeting specific checks on specific files for efficient validation.

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Development, covering Linting and formatting and Type safety. It works with C++, Ruff and Python. The repository describes itself as: An unappealing collection of Claude Skills and resources.

When your agent uses it

  • Tasks that involve Linting and formatting
  • Tasks that involve Type safety

Example prompts

  • “/lint”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Bash, Read, Grep, Glob, TodoWrite

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Always format after editing - Use hatch run lint:fmt -- immediately after code changes
  2. Run comprehensive checks before committing - Use hatch run lint:checks before pushing
  3. Target specific files - Use -- syntax to validate only what you changed, not the entire codebase
  4. Fix auto-fixable issues - Use fmt instead of manually fixing style issues
  5. Type check after adding types - Use hatch run lint:typing -- after adding type annotations

What it can do on your machine

Read from SKILL.md and the folder at commit 1056d29. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read
    • Grep
    • Glob
    • TodoWrite

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • ruff

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lint loads about 2.2k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 824 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read, Grep, Glob, TodoWrite

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 824 words (~2,242 tokens).

“This skill helps you efficiently validate and format code using the project's comprehensive linting infrastructure.”

Questions about Lint

What does Lint do?

Run targeted linting, formatting, and code quality checks on modified files. Lint is an agent skill from Microck/ordinary-claude-skills. Run targeted linting, formatting, and code quality checks on modified files.

When should I use Lint?

Lint fits situations like: tasks that involve Linting and formatting; tasks that involve Type safety.

How do I install Lint in Claude Code?

Run `npx skills add Microck/ordinary-claude-skills --skill lint -a claude-code`. Or copy the skill folder (skills_all/lint in Microck/ordinary-claude-skills) into .claude/skills/lint in your project. Claude Code loads it when a task matches its description.

How do I install Lint in Codex?

Run `npx skills add Microck/ordinary-claude-skills --skill lint -a codex`. Or copy the skill folder (skills_all/lint in Microck/ordinary-claude-skills) into .agents/skills/lint in your project. Codex loads it when a task matches its description.

Can I use Lint in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Microck/ordinary-claude-skills --skill lint -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/lint, .gemini/skills/lint, .github/skills/lint and .opencode/skills/lint in your project.

What does Lint need to run?

Going by SKILL.md and its folder, Lint needs the command-line tools its instructions call (ruff). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Bash, Read, Grep, Glob, TodoWrite.

Does Lint access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Lint safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Lint use?

Lint has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Lint use?

About 2.2k tokens (SKILL.md is roughly 9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Lint?

Skills that share tags, products or a category with Lint: Minimizing Ty Ecosystem Changes (astral-sh/ruff, 50k stars), Kedro Babysit (kedro-org/kedro, 11k stars), Update Dependencies (alorence/django-modern-rpc, 111 stars) and Ha Code Quality (FutureTense/keymaster, 349 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Lint?

Microck (a GitHub user) maintains it in Microck/ordinary-claude-skills, which has 403 GitHub stars. The repository holds 91 skills in this directory. The repository was last updated on September 6, 2026.
