# Implementation Subagents Fresh subagent per task. One combined review per completed batch. Parallel when independent, sequential when dependent. ## When to Use Subagents **Use when:** - 2+ independent work items do not share state or files - Each work item has explicit requirements, constraints, files, and validation - Each problem can be understood without context from the other work items **Don't use when:** - Tasks are tightly coupled (editing the same files) - You need to understand full system state across tasks - Failures are related (fixing one might fix others) - Exploratory work where the problem isn't well-defined yet ## Dispatch Modes ### Sequential (dependent tasks) Tasks with dependencies execute one at a time. Each gets a fresh subagent — no context pollution from previous tasks. ``` Task 1 (Entity) → review → complete Task 2 (Repository, depends on T1) → review → complete Task 3 (Service, depends on T2) → review → complete ``` ### Parallel (independent tasks) Independent tasks dispatch simultaneously. One agent per problem domain. ``` Task A (auth tests) ──→ review → complete Task B (billing tests) ──→ review → complete ← concurrent Task C (notification tests) ──→ review → complete ``` **Independence check:** Would fixing Task A affect Task B? Would they edit the same files? If no to both, dispatch in parallel. For shared-tree parallel work: 1. Assign each task an exclusive file list before dispatch 2. Do not let implementers stage or commit ...
