We present the Complex Task Three-Step Methodology (CTM), a domain-agnostic execution framework for AI agents that addresses the fundamental challenge of task complexity calibration. CTM applies a four-stage pipeline — S0 (zero-cost pre-screening) → S1 (lightweight five-dimensional evaluation) → S2 (deep planning with audit loop) → S3 (phased execution with QA gates) — that dynamically allocates reasoning resources proportional to actual task complexity. Key innovations include a DAG-based parallel execution model replacing forced sequential steps, a two-layer pre-screening architecture that bypasses planning for ~80% of simple tasks, versioned blueprint snapshots for checkpoint recovery, and a recursive sub-agent delegation model with hard depth limits. Deployed in production across development, research, content creation, and operations workloads, CTM reduces average token overhead to 50-80 tokens per message while achieving 92% complexity classification accuracy.
