Iterative Retrieval Pattern

Solves the "context problem" in multi-agent workflows where subagents don't know what context they need until they start working.

The Problem

Subagents are spawned with limited context. They don't know:

• Which files contain relevant code
• What patterns exist in the codebase
• What terminology the project uses

Standard approaches fail:

• Send everything: Exceeds context limits
• Send nothing: Agent lacks critical information
• Guess what's needed: Often wrong

The Solution: Iterative Retrieval

A 4-phase loop that progressively refines context:
