Claude Code keeps track of which skills it has already listed to the model in each session, or for each helper agent. Before it sends the skill list, it now removes any skills that have been replaced from that record. A skill swapped out mid-session can therefore be announced to the model again instead of being treated as already sent.\n\n**Why**\n\nIn practice, the model can hear about an updated skill rather than relying on the version it was told about earlier.\n\n- Area: Skills\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
