Inbox Triage

Sorts a week of inbox into five buckets, drafts the replies, and writes you a dated report, without moving a single message until your rules file says it can.

What it produces

  • A triage report, triage-YYYY-MM-DD.md, saved to OneDrive at /Documents/Cowork/triage/, with counts and per-category tables for needs-reply-today, needs-reply-this-week, waiting-on-others, FYI and noise.
  • Reply drafts in your Drafts folder for the messages that need answers, each labelled DRAFT on the first line. Nothing is ever sent.
  • Moves and archives only for the senders and subject patterns you list yourself in references/triage-rules.md. Until you edit that file, the skill reports and drafts but touches nothing.
  • actions-YYYY-MM-DD.md as a file fallback if you ask for follow-up tasks and Planner or To Do writes cannot be verified.

What to say to it

  • “Triage my inbox from the last week.”
  • “What needs a reply today? Draft the replies for me.”
  • “I am back from two weeks of leave, catch me up on my inbox and sort it into a report.”
  • “Clean up my inbox using my triage rules.”

Cowork has to be switched on for you by an admin, and it is off by default. Custom skills are not supported on a phone or tablet, so use a laptop or desktop.

Cowork checks the file when you upload it and tells you if something is wrong, so you will know either way.
