Subagent Driven Development

Subagent-Driven Development

Create and execute plan by dispatching fresh subagent per task or issue, with code and output review after each or batch of tasks.

Core principle: Fresh subagent per task + review between or after tasks = high quality, fast iteration.

Overview

Executing Plans through agents:

• Same session (no context switch)
• Fresh subagent per task (no context pollution)
• Code review after each or batch of task (catch issues early)
• Faster iteration (no human-in-loop between tasks)

Supported Types of Execution

Sequential Execution

When tasks are tightly coupled and need to be executed in order.

• Dispatch one agent per task or issue
• Let it work sequentially
• Review the output and code after each task or issue

Parallel Execution

When you have multiple unrelated tasks (different files, different subsystems, different bugs).

• Dispatch one agent per independent problem domain
• Let them work concurrently
• Overall review after all tasks are completed

Parallel Investigation

Special case for multiple unrelated failures that can be investigated without shared state or dependencies.
