When it takes its fallback route, it now checks which skills from MCP servers were loaded and keeps a note of them. Skills are packaged instructions Claude Code can load, and MCP servers are connectors that give it outside tools or data. If that check fails, Claude Code reports an error.\n\n**Why**\n\nSkills from MCP servers are more likely to remain available after a conversation has been shortened.\n\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
