What It Checks

• JSON parse errors before a settings file is committed.
• Whether hook event arrays live under the hooks object.
• Common hook handler shape for command, http, prompt, agent, and mcp_tool entries.
• Matcher shape problems, including array matchers where a pipe-separated string is expected.
• Hook events that normally ignore matchers.
• Project/user/settings location hints for keys that belong in a different Claude Code configuration file.

The app does not upload pasted settings. All analysis runs in the browser.
