Building production agents: the observability layer

- What happened
- Pydantic released Logfire, an AI-native observability platform that traces agent execution across the full stack using OpenTelemetry standards.
- Why it matters
- Engineers shipping production agents need this to debug non-deterministic failures that don't throw errors but produce confidently wrong answers.
- Watch out
- Logfire is opinionated and Pydantic-focused. Adoption requires understanding that traditional APM tools and LLM-only tracing miss critical signals in agentic loops.

The patterns behind this
- Agent Observability & Tracing
- Agentic Context Engineering (Evolving Playbook)
- Error Handling and Recovery Patterns
Each one covers how the technique works, when it earns its cost, and where it breaks.
