mailbox-handoff

Mailbox routing and handoff verification across Codex, Claude, and Gemini is automated by scanning the newest SESSION_HANDOFF_*.md file, extracting intent, and executing actions in the proper workspace. It ensures messages are read, routed, and responded to deterministically across all three environments.

Scanning a SESSION_HANDOFF markdown file and routing actions requires deterministic inbox monitoring that reads the newest file, determines the required action, and routes or responds accordingly. This ensures cross-root verification and synchronized inbox workflows across Codex, Claude, and Gemini.

Cross-root verification does check for handoff presence across canonical and shadow roots and reports any inconsistencies. This mechanism keeps inbox workflows synchronized and ensures messages are routed deterministically across the triad workspace environments.

You can use Postman, Scribe, and Polisher together for integrated handoff processing, messaging, and state refresh. These components automate the triad mailbox routing workflow to ensure deterministic message reading, routing, and verifiable response emission with change logs.

Inconsistent routing across different AI roots happens when handoff presence is not verified across canonical and shadow roots. Applying deterministic inbox scanning to extract intent and execute actions in the proper workspace ensures a single, verifiable response with change logs.

You do not need to manually emit change logs after processing a triad mailbox handoff. The automation scans the newest SESSION_HANDOFF_*.md, executes actions in the proper workspace, and automatically emits a single, verifiable response with the required change logs.
