Article: Agentic Fitness Functions: Extending Evolutionary Architecture Beyond Deterministic Rules

Engineering teams are deploying AI agents to police their own architecture—not as pilots, but as continuous governance.

Why it matters

Agentic fitness functions represent a practical application of AI agents to software architecture governance, extending traditional deterministic rules with judgment-based evaluation. This is an architectural pattern that practitioners building complex systems will encounter and need to understand.

The key facts

5 to know
  1. Agentic fitness functions combine AI agents with versioned rubrics for architecture evaluation

  2. Addresses judgment-heavy concerns: boundary fidelity, semantic contract drift, stale ADR assumptions

  3. Evolutionary architecture governance via continuous, calibrated feedback loops

  4. Published in InfoQ, targeting architecture and engineering practitioners

  5. Authors: Hemant Kumar Mahato, Łukasz Sieczkowski, Vijayasenthilkumar Kuppusamy
