What problem does it solve? Mailbox work often fails silently: drafts get written without reading the thread, sends are claimed without proof, and the wrong account or channel gets used. This Skill provides an evidence-first operator workflow for real mail surfaces so every triage, draft, reply, or send ends in a verifiable state. ## Core Features & Use Cases - Evidence-first sending: Never claims a message was sent without a Sent-folder or client-side confirmation, and reports exact status words (drafted, sent, blocked, awaiting verification). - Thread-aware drafting: Reads the existing thread, identifies the last outbound touch, and surfaces commitments or unanswered questions before composing. - Account and channel discipline: Resolves the exact mailbox account, recipient, and action type before acting, and hands off DM or iMessage tasks to the appropriate workflow. - Use Case: You ask whether a proposal email to an investor was actually sent. The Skill checks the correct account's Sent folder, confirms the exact message, and reports sent status with proof rather than guessing. ## Quick Start Triage my inbox, draft a reply to the open investor thread, and confirm whether my last follow-up email was actually sent.
