Seven tools matching existing fable-mcp contracts: - fable_list/get/create/update_project (no delete; archive via status) - fable_list/create/update_milestone (no get; no delete) LLM-era similarity-check / 'confirmed' guard for create_project is NOT replicated — Claude doesn't need it. The service's auto-summary regeneration side effect (services.projects.update_project) stays for now; gets removed in Phase 7 along with all other LLM code. Notable sentinels: - update_milestone: order_index=-1 means "leave unchanged" (0 is valid) - create_milestone: description="" becomes None at the service layer Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
