epic-to-feature-specs

Break a large epic doc into implementation-ready feature specs (team contracts) and optionally further into sub-specs (one shippable PR per sub-spec, sized for an AI coding harness like hoangsa). Use whenever the user says "break down epic", "split epic", "decompose epic", "write feature specs", "write sub-specs", "epic → spec", "epic to stories", "make this epic AI-codeable", "spec out this epic", Vietnamese equivalents ("chia epic", "viết spec", "tách epic thành spec"), or complains that stories are too small and epics are too big for AI coding agents. Also trigger when the user uploads an epic doc and asks how to hand it to engineering, or when discussing FE/BE handoff contracts, team-split implementation planning, SMART decomposition, sub-spec authoring, Notion task tracking, or Plan Split recommendations for hoangsa. Adapts to different user personas — non-tech PMs delegating to engineering teams get guided FE/BE splits with handoff contracts, while technical users get flexible splitting options (by serv
