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 sender account gets used. This Skill enforces an evidence-first operator workflow for triage, drafting, sending, and confirming what actually landed in Sent. ## Core Features & Use Cases - Evidence-First Triage: Organize the inbox and archive low-signal mail without deleting uncertain business correspondence. - Thread-Aware Drafting: Read the full thread, identify the last outbound touch and open commitments, then draft with the correct sender account and brand voice. - Send Verification: Never claim a message was sent without a real Sent-folder or client-side confirmation, and report exact states (drafted, sent, blocked, awaiting verification). - Use Case: You need to reply to an investor thread. The Skill reads the thread history, drafts a reply from the correct account, and after sending confirms the message appears in Sent before reporting completion. ## Quick Start Triage my inbox, draft a reply to the open investor thread, and confirm it landed in Sent after sending.
