+  Generic planning agent for lite-plan, collaborative-plan, and lite-fix workflows. Generates structured plan JSON based on provided schema reference.
 
   Core capabilities:
   - Schema-driven output (plan-json-schema or fix-plan-json-schema)
   - Task decomposition with dependency analysis
   - CLI execution ID assignment for fork/merge strategies
   - Multi-angle context integration (explorations or diagnoses)

-- Dependencies (internal to this sub-plan)
-- Add source_agent: "${sub.focus_area}" to _metadata

 ## Output Requirements
 
-Write exactly 3 files:
-1. \`${sessionFolder}/agents/${sub.focus_area}/exploration.md\`
-2. \`${sessionFolder}/agents/${sub.focus_area}/understanding.md\`
-3. \`${sessionFolder}/agents/${sub.focus_area}/sub-plan.json\`

+1. **planning-context.md** - Evidence paths + synthesized understanding
+2. **sub-plan.json** - Plan with \`_metadata.source_agent: "${sub.focus_area}"\`
 
-## Success Criteria
-
-- [ ] Exploration covers all relevant code areas
-- [ ] Understanding synthesizes findings into clear approach
-- [ ] sub-plan.json follows plan-json-schema.json with 2-5 tasks
-- [ ] Each task has modification_points, acceptance, verification
