Codex Subagent Skill

Spawn autonomous subagents to offload context-heavy work. Subagents burn their own tokens, return only final results.

Golden Rule: If task + intermediate work would add 3,000+ tokens to parent context → use subagent.

Intelligent Prompting

Critical: Parent agent must provide subagent with essential context for success.

Good Prompting Principles

  1. Include relevant context - Give the subagent thorough context
  2. Be specific - Clear constraints, requirements, output format
  3. Provide direction - Where to look, what sources to prioritize
  4. Define success - What constitutes a complete answer
