Basecamp Doctor

Run the structured diagnostic:

basecamp doctor --json

Interpret every check by status:

• pass: working correctly.
• warn: usable, but follow-up is recommended.
• skip: not run because it is unauthenticated or not applicable.
• fail: broken and needs attention.

Report failures and warnings with their hint fields. Also inspect the top-level breadcrumbs array and preserve its structured cmd next steps, because a breadcrumb can provide a more specific action than a check hint. Use these common remediations when relevant:

• Basecamp authentication: basecamp auth login
• Agent plugin installation or version: basecamp setup agents (honors BASECAMP_SETUP_AGENT)
• Codex plugin specifically: basecamp setup codex
• Claude Code plugin specifically: basecamp setup claude

Every remediation above runs without a terminal. Bare basecamp setup is the human first-time flow and is not one of them: it opens browser OAuth and refuses with a usage error in machine-output modes or unless stdin, stdout, and stderr are all terminals. basecamp setup --customize additionally asks the user to choose each default. Suggest either to a human at a terminal if useful, but never run them yourself — use the subcommands above.

Do not read, print, or request credential files. If every check passes, say that Basecamp and its agent integration are ready.
