CCA-F: Claude Certified Architect — Foundations

The Claude Agent SDK's orchestrator/coordinator-worker pattern is designed so that the coordinator agent itself reasons about each incoming query and dynamically determines which subagents are actually needed, rather than relying on a fixed set of hardcoded rules, categories, or a separately trained classifier. Static approaches — a binary fast-path/full-pipeline split, predefined pattern-to-subagent mappings, or a periodically retrained complexity classifier — all require ongoing manual maintenance and struggle to keep up with a query distribution that is diverse and continuously evolving as users find new use cases. Letting the coordinator assess query requirements at runtime and invoke only the necessary subagents (e.g., skipping document analysis and synthesis for a simple fact lookup, but running the full search-analyze-synthesize-report chain for comparative research) preserves both efficiency for simple queries and thoroughness for complex ones, and it generalizes automatically to new query types without requiring redesign of routing rules or model retraining. This mirrors Anthropic's guidance that model-driven, dynamic decision-making is preferable to rigid predefined workflows when task variety and unpredictability are high.
