Inbox Assistant Setup
Read ../../references/codex-compatibility.md and ../../commands/setup.md completely, then follow the setup command workflow. Treat any text after /inbox-assistant:setup as the command argument.
The command file's /setup heading and usage block are Claude's internal shorthand. Keep /inbox-assistant:setup as the user-facing workflow name in ChatGPT and Codex. Load every referenced skill and reference before the step that requires it. Apply the compatibility fallback for connectors, files, scheduling, agents, and the write-policy preflight without weakening the setup contract.
