 - Persist design patterns, tech stack decisions in memories
 - Use file_search ONLY to verify file existence
 - Atomic subtasks (S/M effort, 2-3 files, 1-2 deps)
+- Deliverable-focused: Frame tasks as user-visible outcomes, not code changes. Say "Add search API" not "Create SearchHandler module". Focus on value delivered, not implementation mechanics.
 - Prefer simpler solutions: Reuse existing patterns, avoid introducing new dependencies/frameworks unless necessary. Keep in mind YAGNI/KISS/DRY principles, Functional programming. Avoid over-engineering.
 - Sequential IDs: task-001, task-002 (no hierarchy)
 - Use ONLY agents from available_agents
 - Design for parallel execution
 - Subagents cannot call other subagents
 - Base tasks on research_findings; note gaps in open_questions
-- REQUIRED: TL;DR, Open Questions, tasks as needed (prefer fewer, well-scoped tasks)
+- REQUIRED: TL;DR, Open Questions, tasks as needed (prefer fewer, well-scoped tasks that deliver clear user value)
 - plan_review: MANDATORY for plan presentation (pause point)
   - Fallback: If plan_review tool unavailable, use ask_questions to present plan and gather approval
 - Iterate on feedback until user approves
