npm install --save-dev prettier
brew install shellcheck
# or
npm install -g shellcheck
The format command automatically scopes to Claude files only, so it won't conflict with your project's existing formatters.
Create .markdownlint.json in your project root:
{
"default": true,
"MD013": false,
"MD033": {
"allowed_elements": ["kbd", "br"]
},
"MD041": true,
"MD031": true,
"MD032": true,
"MD040": true,
"MD022": true
}
claudelint format will automatically use this configuration.
Create .prettierrc.json in your project root:
{
"semi": true,
"singleQuote": true,
"printWidth": 100,
"tabWidth": 2,
"useTabs": false,
"arrowParens": "always",
"endOfLine": "lf",
"proseWrap": "preserve"
}
claudelint format will automatically use this configuration.
Add to package.json scripts:
{
"scripts": {
"format:claude": "claudelint format --fix",
"format:claude:check": "claudelint format --check",
"lint:claude": "claudelint check-all"
}
}
Add to pre-commit hooks:
#!/bin/sh
claudelint format --check

I do it
Interactively helps users optimize their CLAUDE.md files. Use when user asks to "optimize my CLAUDE.md", "my CLAUDE.md is too long", "improve organization", or "split my CLAUDE.md". Runs validation, explains issues conversationally, and helps create @import files to reduce size and improve structure.
Runs comprehensive claudelint validation on all Claude Code project files. Use when user asks to "check everything", "run all validators", "full audit", "validate my entire project", or "what's wrong with my config". Validates CLAUDE.md, skills, settings, hooks, MCP servers, and plugin manifests.
Validates CLAUDE.md files for size, imports, and structure. Use when user asks to "check my CLAUDE.md", "why is my CLAUDE.md too long", "validate imports", or "fix CLAUDE.md errors". Checks file size limits (30KB warning, 50KB error), @import directives, frontmatter in .claude/rules/, and section organization.
Validates Claude Code hooks.json files for schema, events, and commands. Use when user asks to "check my hooks", "validate hooks.json", "hook errors", "why isn't my hook firing", or "hook event types". Validates hook events, types (command, prompt, agent), matcher patterns, and command script references.
