lint-staged-claude-hook

Use your lint-staged config as a Claude Code hook.

Install

Requires lint-staged >=16.0.0 as peer dependency.

npm install lint-staged lint-staged-claude-hook

Usage

CLI

# Print commands for files
lint-staged-claude-hook src/index.js src/utils.js

# Execute commands
lint-staged-claude-hook --run src/index.js

# JSON output
lint-staged-claude-hook --json src/index.js

As Claude Hook

Add to .claude/settings.json:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": { "tool_name": "Edit|Write" },
        "hooks": ["lint-staged-claude-hook --run"]
      }
    ]
  }
}

The CLI reads Claude's hook JSON from stdin, extracts tool_input.file_path, and runs your lint-staged commands.
