Agent Delegation Rules

Model Routing

Always set model: when spawning subagents. Haiku costs 12× less than Sonnet — use it for all search and explore work.

Never spawn an Explore or search agent without model: haiku. Never spawn an agent if the task has fewer than 3 tool calls worth of work. Never let subagents inherit your session context — construct exactly what they need in the prompt.

Hallucination Prevention

• Never invent or guess file paths — verify with Glob/Grep before referencing
• Never assume import paths, function names, or API routes exist — read the file first
• If an agent reports a file path or symbol, verify it exists before acting on the report
