Focus Tree

Session content focus tree with checklist tracking. Extracts decisions, TODOs, constraints, and context into a single-root hierarchical structure for better conversation alignment and task management.

Core Principles

1. Alignment — Maintain synchronized understanding between agent and user. The FOCUS.md serves as a shared source of truth that both parties can reference.

2. Focus — Keep the agent anchored to the current task. Prevents drifting between topics or losing track after session compactions.

3. Planning — Enable structured, step-by-step task execution. Break down complex work into manageable hierarchical sub-tasks with clear progress tracking.

When to Read FOCUS.md

• Every session start (before responding to first message)
• After every compaction (if context feels thin, read it)
• When the user asks about current work ("what are we doing?", "where were we?")
