Each skill in that list now carries a digest, a short fingerprint of its content. A skill is sent again only when its name or its digest has not appeared in the conversation yet. Unchanged skills are not sent again.\n\nWhen the `Skill` tool is unavailable, the list is not sent at all.\n\nBefore, Claude Code tracked sent skills by name only, for the whole session.\n\n**Why**\n\nA skill you edit during a session is announced to Claude again, and skills that have not changed are repeated less.\n\n- Area: Skills\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
