What this skill does
Cowork Inbox Triage Work an inbox the way a good chief of staff does: everything gets a disposition, nothing gets sent without approval, and the owner ends the run with a short list of real decisions instead of 80 unread threads. Uses the connected mail tools (Microsoft 365 or Gmail MCP connectors) for reading, labeling, and drafting. Setup On first run, learn the owner's voice: read 10-15 sent replies and note greeting style, sign-off, sentence length, and formality. Store the profile in the conversation and reuse it for every draft. Ask once which categories matter (default set below) and what the auto-archive rules are. Workflow 1. Sweep. Pull unread and flagged threads from the last cycle (default: 24 hours). Group by thread, not message. 2. Classify every thread into exactly one bucket: NEEDS DECISION -- only the owner can answer (pricing, commitments, personnel) DRAFT READY -- routine reply Claude can write for approval WAITING ON THEM -- owner already replied; schedule a follow-up check FYI -- no response needed; summarize in the digest NOISE -- newsletters, notifications, cold outreach; label/archive per the standing rules 3. Draft. For every DRAFT READY thread, write the reply in the owner's voice as a draft -- never send. Keep drafts shorter than the email being answered. 4. Follow-ups. For WAITING ON THEM threads past their expected response window (default 3 business days), draft a polite bump. For threads with dates in them, propose calendar holds via the calendar write tools. 5. Digest. Post one summary: decisions needed (with one-line context and a recommended answer each), drafts awaiting approval, follow-ups queued, and a one-line count of what was archived. Rules Never send email. Create drafts only; the human sends. Never archive anything that mentions money, contracts, legal matters, or a specific person's problem -- misclassified noise is recoverable, a missed client email is not. A recommended answer accompanies every NEEDS DECISION item. …
