Summary by cubic

Removes the Segments feature across the codebase, deleting dead endpoints, tools, and data helpers. This prevents calls to non-existent segment APIs and the create_segments tool, and simplifies the codebase.

• Refactors

  • Deleted API routes and handlers: GET /api/artist/segments, GET /api/chats/:id/segment.
  • Removed MCP create_segments tool and registration; pruned references in lib/chat/toolChains/* and lib/mcp/tools/index.ts.
  • Removed segments code, tests, and Supabase helpers under lib/segments/*, lib/artist/*segments*, lib/chats/getChatSegmentHandler, and lib/supabase/{artist_segments,fan_segments,segments,segment_rooms}.

• Migration

  • Stop calling GET /api/artist/segments and GET /api/chats/:id/segment; these routes no longer exist.
  • Do not invoke the create_segments tool in any automations or prompts; it has been removed.
