A no-fluff comparison of the three dominant agent frameworks — what they're good at, where they break, and how to pick one for production workloads. A no-fluff comparison of the three dominant agent frameworks — what they're good at, where they break, and how to pick one for production workloads. Engineers are picking frameworks based on hype, not fit. Includes controls, pitfalls, and a phased implementation path. A no-fluff comparison of the three dominant agent frameworks — what they're good at, where they break, and how to pick one for production workloads. Why this matters Teams are under pressure to deliver AI capability quickly, but speed without control creates operational and governance risk. This guide focuses on practical execution patterns that hold up in production. Prerequisites Clear ownership for delivery and risk decisions. Baseline observability for model and tool behaviour. Defined quality and security acceptance criteria. Practical ...

How current agent architectures (tool use, multi-step reasoning, memory) are evolving into deployable systems rather than demos. How current agent architectures (tool use, multi-step reasoning, memory) are evolving into deployable systems rather than demos. Agent frameworks like OpenAI’s Evals, CrewAI, and LangGraph are changing the baseline for production AI — engineers need clarity on trade‑offs.

A practical architecture for building AI agents with MCP, including boundaries, observability, and failure handling. AI agents are moving from demos to production systems, and MCP is quickly becoming a common protocol for tool and context integration. This guide covers a practical baseline architecture. Why this matters now As of 2025-2026, MCP support and agent workflows have expanded across major ecosystems, and teams need interoperable patterns rather than provider lock-in. Baseline architecture Orchestrator layer : plans tasks, manages tool calls, and handles retries. Model layer : reasoning/generation model with explicit prompt contracts. MCP tool layer : context servers for docs, repos, tickets, and internal systems. Policy layer : security rules, redaction, and allowed-tool boundaries. Observability layer : traces, token costs, tool latency, failure telemetry. Key design rules Treat MCP servers as untrusted inputs unless explicitly verified. Whitelist to...
