Architecture decisions, trade-offs, and the code behind them.
How to build custom LangChain callback handlers with OpenTelemetry integration for vendor-independent observability — what to trace, how to structure it, and what it costs.
A voice agent that speaks still needs to listen. Duplex behavior, interruption policy, and yield rules decide whether the agent feels useful or intrusive.
Enterprise CrewAI deployments require auth integration, tenant isolation, and audit trails the framework does not provide. Here are the patterns that work in production.
Realtime voice agents receive partial transcripts, delayed intent, and ambiguous address signals. Treating fragments as finished commands creates brittle meeting behavior.
Three advanced LangGraph interrupt patterns — conditional approval, batch review, and timeout handling — with production Python implementations.
Voice-agent demos fail when they ignore turn-taking, disclosure, context boundaries, cost controls, artifacts, and human-owned decisions.
How delegation chains, memory retrieval, tool retries, and uniform model assignment compound token costs in CrewAI — and the controls that contain them.
How to design tool permissions for production AI agents: blast-radius classes, approval boundaries, delegation inheritance, policy checks, and rollout rules.
LangChain's 0.1→0.3 migration path broke production systems in ways teams did not anticipate. These patterns reduce the damage next time.
How to build an evaluation layer for production AI systems: golden sets, failure taxonomies, regression gates, tool choices, thresholds, and release criteria.
Diagnose CrewAI failures by layer: delegation loops, role confusion, tool errors. Structured logging, trace correlation IDs, and callback handler patterns.
A practical guide for founders and CTOs: the signs your AI agent no longer needs more prompt tuning and now needs principal-level engineering judgment.
