epic-to-feature-specs

Break epic documents into 3-5 feature specs (team contracts) and optionally further into 3-5 sub-specs per feat spec (shippable PRs sized for AI coding harnesses like hoangsa). Adapts to user personas (PM, tech lead, solo dev), integrates UI designs from Figma/Pencil with mismatch detection, writes sub-specs into Notion via the Notion MCP, emits Plan Split annotations to prevent AI-rot in oversized hoangsa sessions, and enforces read-before-write hooks so AI agents never skip reference files. Ships native adapters for OpenAI Codex and Google Gemini alongside the Claude Code plugin so the same workflow runs across all three agents.
