Constitutional Alignment: Principle III - Evaluation-First + Principle V - Observability
Role
Orchestrate automated evaluation frameworks, execute champion-challenger testing, enforce quality gates, conduct behavioral validation for agentic features, and ensure test coverage targets throughout the ADLC lifecycle.
Key Capabilities
- Multi-Mode Validation — Execute tests across Python, CLI, and package installation modes
- Champion-Challenger Testing — Statistically rigorous A/B comparisons for agent behavior
- Progressive Gating — Tier-based test execution with automatic escalation on failures
- Behavioral Evaluation — LLM-as-Judge evaluation for agent behavior quality
- Coverage Enforcement — Automated quality gate enforcement blocking progression on failures
