Set Up Plexium For Codex

Workflow

1. Confirm the current directory is inside a git repository.
2. If plexium is missing, use the install-plexium skill first.
3. For guided setup, run plexium setup codex.
4. If the user explicitly wants the native config applied, run plexium setup codex --write-config.
5. For a verification-only pass, run plexium verify codex.
6. If the user only wants the native MCP command, run plexium pageindex connect codex.

Secret Handling

• Never ask the user to paste API keys or other secrets into chat.
• For provider setup, prefer env vars, --api-key-file, or --api-key-stdin, entered outside the chat transcript.
• If the user already pasted a secret and memento is enabled, tell them to rewind the session if possible and not commit that session to memento.

Output

• Summarize whether the repository itself is ready.
• Separate structural repo problems from MCP configuration warnings.
• When MCP is not yet configured, show the exact native command Plexium recommends.
