Read context_window config (default 200000) in execute-phase and plan-phase workflows. When >= 500000 (1M-class models), subagent prompts include richer context: executor agents receive CONTEXT.md, RESEARCH.md, and prior wave SUMMARYs; verifier agents receive all PLANs, SUMMARYs, and REQUIREMENTS.md; planner receives prior phase CONTEXT.md for cross-phase decision consistency.
At 200k (default), behavior is unchanged.
