[Agent · Phase 13] task_atomizer

[jeremymanning]

Parent phase: #57

Purpose

Decompose an over-budget parent task into sub-tasks each fitting the leaf wall-clock budget; recursive up to MAX_ATOMIZATION_DEPTH.

What it produces / drives

Writes code/.tasks/<task_id>.atomize.yaml (research-side) or paper equivalent; tasker re-reads on next round.

Dependencies

This agent depends on output from: implementer, paper_implementer

Acceptance criteria

• Sub-tasks each fit LEAF_TASK_BUDGET_SECONDS
• Sub-task graph forms a valid DAG (no cycles)
• Recursion bounded by MAX_ATOMIZATION_DEPTH

Manual test plan

1. Manually craft a task line with verdict=atomize from the implementer
2. Verify code/.tasks/<id>.atomize.yaml lists sub-tasks with budgets ≤LEAF
3. Re-run tasker: sub-tasks appear in tasks.md as new T### entries
