Agent workflows belong in code, not just visual builders
OpenAI is winding down Agent Builder and platform Evals. Production agent workflows need code, tests, traces, and reviewable contracts.
-
Your agent installs Markdown from the internet and runs it. We spent 20 years learning not to do that.
Agent skills are dependencies with none of the controls. What the 2026 research found, why scanners miss it, and seven fixes for platform teams.

Round-robin is malpractice for LLM traffic: what the Inference Gateway actually fixes
The Gateway API Inference Extension is GA. Why a normal Kubernetes Service balances model servers badly, and how to tell if you need an InferencePool.

GPU utilization is a lying metric: the unit economics of self-hosted inference
You can run a GPU at 100% utilization and waste most of it. The cost model that predicts your inference bill, and the five levers in payback order.
-
Agents are deleting production and nobody is writing the postmortem
Your incident template assumes a deterministic system and a human decision-maker. Agent incidents have neither. Five sections that fix the template.
-
Most of your AI platform's traffic doesn't need a frontier model
Small models got good enough in 2026. But the win isn't using them — it's making model choice a platform tier with a router, eval gate, and demotion path.

MCP 2026-07-28 shipped: the stateless core is the headline, header routing is the story
The final MCP spec deletes sessions, mirrors requests into HTTP headers, and turns elicitation into multi-round-trip calls. What breaks, and what to audit.

Google just published the reference architecture for agentic SRE
Google SRE splits autonomous incident response into reasoning, actuation, and evaluation. The split is the lesson — here's what to copy at normal scale.
-
The EU AI Act blinked — your logging requirements didn't
The EU AI Act omnibus moved high-risk deadlines to 2027–28. The logging, oversight, and inventory work is still yours — and reliability needs it anyway.

Your agents need identities, not API keys
Every AI agent is a non-human identity — most run on shared, long-lived API keys no IAM review sees. Per-agent identity and your credential blast radius.
-
Token FinOps: the third budget your agents are spending
Error budgets, context budgets — agents add a third: dollars. Agent tasks burn 5–30× chatbot tokens, and cost-per-token is the wrong metric.
-
Tracing the agent loop: OpenTelemetry's GenAI conventions, read like an SRE
Your agent is a distributed system wearing a chat interface. OpenTelemetry's GenAI conventions make it debuggable — what v1.41 covers and what's moving.

Frontier models still fail half your incidents: reading ITBench-AA like an SRE
ITBench-AA put frontier models against 59 real Kubernetes incident diagnoses — all scored below 50%. What the benchmark measures and how to use it.
-
Autonomy is a budget, not a toggle: error budgets for AI operators
SRE solved runaway release risk with error budgets. The same mechanism governs AI agents: authority per action class, demoted fast, promoted slow.
-
The reliability gap: a framework for trusting autonomous SRE agents
An autonomous airline agent rebooked 1,247 passengers wrong in one weather event. Trusting agents is a reliability problem — here's how to measure it.

The Five Types of Agentic Memory (and When to Use Each)
Agentic memory is five things — working, episodic, semantic, procedural, entity — each with its own storage, eviction, and failure mode. A decision guide.
-
Agentic AI Patterns: The Decision Guide (Part 1 of 3)
Six agentic AI patterns — ReAct, Plan-and-Execute, Critic, fan-out, HITL gate, Supervisor — with a decision flowchart for picking one before you build.

Making Claude Code Work with Locally Deployed Models
Claude Code can point at Ollama, vLLM, LM Studio, or any private endpoint. When that's the right call, exactly how to configure it, and what you give up.
-
OKF: The Missing Context Layer for AI Agents
The Open Knowledge Format gives agents a structured vocabulary for what data they're touching and where it came from — auditable, not blind, reasoning.
-
Chaos engineering for MCP: break your tool-call plane before production does
LLM calls fail 1–5% of the time and agent tasks fan out into 10–20 tool calls. How to fault-inject your MCP layer with mcp-chaos before production does.

Context engineering: the window is a budget, not a bucket
The context window is your agent's working memory, not a junk drawer. Four operations — write, select, compress, isolate — and a token budget you allocate.

Agent sprawl is your next production incident
Teams shipping AI agents are recreating 2015's microservices sprawl with worse observability. The governance surface that contains it before it pages you.
-
No anonymous inference endpoints — the MCP security principle you're probably violating
The NSA and NIST put MCP on notice: agents are a funnel for prompt injection and privilege abuse. Why 'no anonymous inference endpoints' — and how to comply.
-
Observability for AI systems — what changes when your service calls an LLM
Golden signals miss the failure that pages you: a confident, well-formed, wrong answer. What AI observability adds — context as a span, quality as a signal.

The CAP theorem in AI-native distributed systems
CAP didn't get repealed when LLMs showed up. How the C/A/P trade-offs shift when the datastore is a vector index, context graph, or retrieval layer.
-
NAS vs SAN for GPU workloads — what changed when AI showed up
File vs block was the old NAS-vs-SAN question. GPU training rewrote it. How the calculus shifts when storage has to keep an H100 cluster fed.
