Teaching as System Observability

Teaching as System Observability

Automated evals catch what's measurable. Teaching reveals what's hard to explain. Design the quality gate that catches what both miss.

Curriculum Drift Detection: Keeping Technical Content Correct

Curriculum Drift Detection: Keeping Technical Content Correct

Content decays silently. Five drift detection signals—from broken code to declining pass rates—plus the maintenance cadence and remediation strategies to catch problems before learners do.

Stateful Orchestration for Reliable Course Production

Stateful Orchestration for Reliable Course Production

Production agent pipelines fail silently. Event-driven orchestration with idempotency, failure isolation, and content versioning keeps course content consistent and recoverable.

The Multi-Agent Course Artifact Pipeline

The Multi-Agent Course Artifact Pipeline

Design a six-agent content pipeline that mirrors curriculum team roles, with explicit tool constraints, shared state contracts, and isolated evaluation for each stage.
