How to build a production-ready agent with the Anthropic SDK, step by step
This guide shows how to build a production-ready agent with the Anthropic SDK in Python: the tool-use loop with the Messages API, streaming with backpressure via a bounded queue, prompt caching with cache_control, your own MCP server registered with the Claude Agent SDK, OTel GenAI traces, and a non-root Docker container ready for production.

Mature LLM-as-judge: when to trust and when not
Using an LLM to judge another LLM became widespread in 2024 and remains, in 2026, the only scalable way to evaluate qualitative quality in LLM systems. It is reliable when judge-human correlation exceeds 0.7 on 30 cases and gets recalibrated quarterly; below that threshold, do not trust the number.

Claude Opus 4.7 and long-horizon tasks: real changes
Opus 4.7 launched as Anthropic's most capable model, with emphasis on long-horizon agentic work. After two months of intensive use, these are the practical changes versus Opus 4.6.

FinOps on agent tokens: the invoice that surprises
The first invoice for a production agent usually runs double or triple the estimate. This article walks through five real levers, in priority order, caching, routing, context control, batching, and telemetry, to cut cost without touching perceived quality.

AI-integrated DevOps tools in my daily flow
After fourteen months testing AI-integrated DevOps tools across several teams, the stack that stays is small: Claude Code, Cursor, and Aider for code; PagerDuty AIOps, Datadog Bits AI, and Grafana Assistant for alert triage; and OpenTofu with OPA for infrastructure generation bounded by policy rules.

AI agent incidents: recovery runbooks that work
AI agents fail in production, and what matters is how you respond in the first twenty minutes. This runbook covers severity classification, isolating before investigating, purging contaminated memory, communicating without inventing facts, and turning every incident into a regression test before closing it as done.

LLM red teaming: a practical playbook
LLM red teaming has gone from an esoteric activity to a mandatory practice. With the OWASP Agentic Top 10 and the CSA Agentic AI Red Teaming Guide converging on shared vocabulary, this is the operational playbook any team deploying agents needs to have.

Production-grade agent evaluations: the framework that works
Después de año y medio llenando tableros con agentes en producción, la pregunta que separa equipos que envían fiable de los que van a ciegas sigue siendo la misma: ¿cómo mides que el agente está funcionando?

RICE: a prioritization framework for product roadmaps
The RICE framework is a prioritization methodology created by Intercom that produces a score by combining four factors: Reach, Impact, Confidence, and Effort. It divides the product of the first three by the estimated effort in person-months, so it can compare unrelated initiatives using one objective number.

Prompt Engineering: From Trick to Mature Discipline
Prompt engineering has moved from viral tricks to a discipline with reproducible patterns: few-shot, chain-of-thought, and structured output with function calling. Teams treating prompts like code (versioned, tested, and monitored) get consistently better results than those who improvise.

Post-quantum migration: what is actually happening
Two years after the final NIST standards, post-quantum migration is no longer hypothetical. What has actually been migrated, what remains stuck, where the real operational problems lie, and how the timelines look from April 2026.

Enterprise agent governance: the controls that are no longer optional
After two years of pilots and a year of agents in production, governance has moved from an aspirational committee to an operational control. What audits ask for, what broke in 2025, and which guardrails absorb most incidents.

Lessons from agents in production in 2025: summary for 2026
Durante 2025 cientos de equipos pusieron agentes IA en producción real. A principios de 2026, con datos suficientes, emergen lecciones consistentes sobre qué falla, qué funciona, cuánto cuesta y qué tareas no encajan. Repaso ordenado para equipos que empiezan ahora.

Consolidated platform engineering: who wins and who gets stuck
Tres años después de que platform engineering se convirtiera en palabra de moda, el polvo ha caído. Unas pocas empresas tienen plataformas internas que de verdad aceleran al desarrollo, muchas montaron un portal Backstage vacío y algunas volvieron a DevOps clásico. Análisis de qué distingue a las que ganaron.

Agents that drive the computer: patterns that work
Sixteen months after Anthropic first shipped computer use, with browser-use, OpenAI Operator and Gemini Computer Use all pushing in parallel, agents that drive the browser and desktop have moved from demo to real workflows. Time to review which patterns survive when you run them daily in production.

AI incident postmortems: what they have taught us

LLM-generated documentation: when it helps and when it gets in the way
Large language models have spent two years promising effortless documentation for code, APIs and architecture. After watching dozens of projects try it, clear patterns emerge for where it works and where it just becomes more debt.

LLM guardrails: frameworks and their real cost
Guardrails frameworks promise to filter language-model inputs and outputs to block data leaks, harmful content, or hallucinations. After evaluating four of the most popular ones in production, I cover what they actually do, what latency and billing cost they add, and when they pay off over simpler controls.

AI agent observability: what to instrument first
Agents that chain calls to models, tools and memory are hard to debug without instrumentation designed for them. After a long year running agents in production, I cover what to measure first, which standards are consolidating, and which costly mistakes are avoided by getting the traces right from the start.
