Tool Use
Guides tool selection across three layers: local scripts (zero context cost), MCP proxy (minimal context), and subagent dispatch (isolated context). Ensures the agent uses the cheapest effective layer and never pollutes the main context window with raw tool output. Use when the agent needs external information, current documentation, database access, or multi-step research.
