inbox-triage

Use this skill whenever the user asks to clean up, triage, declutter, or archive low-value Outlook inbox mail - "clean up my inbox", "triage my mail", "declutter my inbox", "sort out newsletters", "archive old resolved threads", "/inbox-triage" - to group only newsletters, auto-notifications, past-event meeting logistics, resolved threads, and redundant duplicates into reviewable move-proposals presented for per-bucket approval before any message moves. Do not use for reading mail, drafting or sending replies, deleting mail, executing moves without explicit per-bucket approval, or acting on messages from the user's manager, direct reports, active threads, flagged mail, or labelled/HR/Legal/Finance/Security senders.

rule · Microsoft 365 Copilot: What is a skill

An agent can have at most 8 skills. Custom skills aren't available in tenants that use Microsoft Purview Information Barriers.

Compatible isn't the same as safe. These verdicts only say whether a skill's files follow Microsoft's documented load rules. The checker reads files and never runs them, and it doesn't review what a skill or its scripts actually do. Read a skill's instructions and scripts before you add it to an agent.
