What problem does it solve? Incoming email arrives continuously but has no durable home: actionable threads get lost, follow-ups are forgotten, and nobody knows which projects are still waiting on a reply. This Skill turns every actionable message into filed project documentation with explicit waiting-on tracking. ## Core Features & Use Cases - Mail ingress filing: Reads Triage stubs and mail mirrors, matches or creates Projects/<slug>/ folders, and updates about.md, todo.md, and daily journals with links instead of duplicated bodies. - Track and reconcile: Creates or hands off mail_* Kanban track tasks per project slug, then reconciles all open tracks when a signal (reply, owner update, outcome report) changes what is still waiting. - Scheduling and owner-reply routing: Applies a decision gate (proceed, closed, owner-review defer, or owner-reply) so meeting negotiation goes to ea-scheduling and non-meeting owner asks go to ea-owner-reply. - Use Case: A confirmation email arrives for a deal thread. The Skill files it under the existing project, completes the superseded waiting-on track, verifies the calendar event, and marks the project done without sending any mail. ## Quick Start Triage the new mail ingress task by filing the thread into the matching project folder and updating its waiting-on tracks.
