Dr. Sarah Chen The first time you deploy an AI agent into production, it will fail in a way you did not anticipate. Not because the model generated a bad output. Not because your prompt was wrong. It will fail because the infrastructure wrapping the model—the harness—was not built to handle the edge cases that only appear under … Read more
A 5-agent research pipeline had been running cleanly for three weeks when the failure reports started coming in. The tasks were completing — no errors, no timeouts, no retries — but the final deliverables were wrong. Not obviously wrong. Subtly wrong. Agent 4 was producing outputs that answered a slightly different question than the one … Read more
I have been skeptical of “year of X” declarations since I watched the industry announce the “year of the enterprise cloud” four consecutive years before enterprise cloud actually arrived. So I do not make this call lightly: 2026 is genuinely the year of the AI agent. Not because the demos got better. Because the conversations … Read more
A customer-facing agent at a mid-sized fintech company spent 11 minutes in a runaway loop last quarter, retrying a failed API call 847 times, generating $2,200 in API costs, and sending 14 partial emails to a single customer before a human noticed and killed the process. The model was performing exactly as designed. The prompt … Read more
The pace of AI agent adoption is accelerating, and with it, the critical infrastructure challenges that separate prototype from production. This week’s signals point to a industry-wide reckoning: organizations are moving beyond novelty use cases and confronting the hard architectural and governance problems that harness engineering exists to solve. 1. Why 2026 is the “Year … Read more
As AI agents transition from proof-of-concept demonstrations into production workloads, the industry is grappling with fundamental questions about governance, observability, security, and architectural rigor. This roundup covers the week’s critical conversations around deploying, monitoring, and governing AI agent systems at scale—issues that define whether 2026 becomes the year agents mature into reliable infrastructure or remain … Read more
The predictions are everywhere. AI will write all the code. Engineering headcount will collapse. Junior developers will be obsolete. Most of these forecasts come from people who have not operated AI-assisted development systems at scale, and it shows. I have spent the past year talking to engineering leaders at companies that are actually running AI … Read more
The inflection point for AI agents has arrived. This week’s industry signal is unmistakable: the market is no longer debating whether AI agents will enter production—it’s grappling with how to make them reliable, observable, secure, and governed at scale. This shift from proof-of-concept to production-grade infrastructure is precisely what harness engineering addresses. Let’s examine the … Read more
You deploy an agent to production. Task completion rate looks acceptable in your logs — roughly 80% success. Two weeks later, a customer files a support ticket: the agent has been silently returning malformed outputs on a specific input pattern. You check your dashboards. Nothing flagged it. You trace backward through the execution logs and … Read more
