Research-first prototype planning

Mine PRISM knowledge base then source-dive gaps into a conductor task

Starting a feature phase when you need instant knowledge synthesis from brain + code to ground the plan before implementation.

• · feature: string (required) — what to plan
• · session_id: string (optional) — driving Claude session for task_link_session emission

• · PRISM brain/memory findings (sources, confidence)
• · coverage gaps (unanswered questions)
• · PRD-style plan (title, summary, actors, views, constraints, journeys, steps)
• · Mermaid plan diagram (sequence/class/flow)
• · Plan markdown doc (## headings, bullets)
• · conductor task created with plan + diagram

• · PRISM MCP (brain_search, brain_understand, memory_recall)
• · parallel agent fleet (coverage judge, 1 agent per gap for source dive)
• · conductor task system

• · PRISM brain initialized with project knowledge
• · Feature string non-empty and not a placeholder
• · Project source code accessible for gaps
• · Conductor task system available

• · Feature is placeholder or empty → script throws before spawning agents
• · PRISM brain unavailable → gaps remain high, source dive compensates
• · Gap source file not found → agent reports unavailable, plan proceeds
• · Plan synthesis timeout → partial plan returned with noted gaps

• · PRISM confidence score returned (0-1) — judge coverage quality
• · Coverage judge explicitly lists gaps needing source dive
• · One agent per gap (not batched) for detailed source findings
• · Plan includes file:line seam citations to actual source
• · Mermaid + markdown plan persisted to conductor task for visibility
