The Cloud Codex — field notes on building with AI agents

Dell booked $12.3 billion in AI server orders in a single quarter — $30 billion year to date, with an $18.4 billion backlog and a five-quarter pipeline the company says is multiples of that, per…

An agent connected to five MCP servers can burn 55,000 tokens on tool schemas before it reads the first word of your request. GitHub's server ships 35 tools at roughly 26K tokens. Slack adds 11…

Every large engineering org eventually wants the same thing: one view of every dependency across hundreds of repositories. Who uses lodash 4.17.20. Which services still pull in the bad Log4j. What…

Internal platforms used to be the exotic option. Now they are the default. A December 2025 Platform Engineering survey of 518 organizations found that nearly 90% of enterprises run internal…

The question being asked in r/kubernetes this week is whether to feed observability data to coding agents. Traces, metrics, logs, the whole stream the system already emits — should the agent that…

The companies with the most control over chip supply on the planet still rent across three cloud providers. That is the fact that should reset how a platform team thinks about AI infrastructure.…

The 1M-token context window is here. Opus 4.8, 4.7, and 4.6, plus Sonnet 4.6, now carry the full million-token context on the Claude API, Amazon Bedrock, and Vertex AI — no surcharge, generally…

A LinkedIn post circulating this week made an observation worth sitting with. AI write-throughput in a serious engineering team can hit fifty pull requests a day. The team's merge-throughput is…

The cloud-runtime question for enterprise Claude is settled. AWS shops route through Amazon Bedrock. Google Cloud shops route through Vertex AI. Direct deployments now sit inside the customer's…

The May 15 piece on access-rents drew a line through every services industry. On one side: access-rents — work that consists of operating an interface the customer cannot operate themselves. On…

Every working stack is the residue of failures the operator did not see coming. The Saturday piece showed the architecture as it stands now. This piece is the inverse — the five specific incidents…

Most "AI is expensive" discourse is vague. The pieces that quote real numbers usually quote enterprise tier list prices for tools the writer does not personally run. The pieces that talk about…

The dotfiles piece from May 22 named hooks as one component of a personal AI stack and moved on. They deserve more than a passing mention. Hooks are the primitive that turns taste into code — the…

Yesterday's piece prescribed building a personal AI stack instead of waiting for the enterprise plan. The natural objection — "fine, but what does that actually look like" — deserves a concrete…

Every senior engineer who has shipped meaningful work in the last thirty years has carried a personal dev environment with them. Emacs configs, vim plugins, shell aliases, dotfiles repos, custom…

The current "Hermes Agent vs Claude Code" framing is the wrong comparison. The two tools live at different layers of the coding agent stack, and most of the YouTube hot takes treating them as…

An article circulating this week argues that faculty AI buy-in in higher education is a human factors engineering problem. The framing is correct. The path the piece describes skips the only two…

Anthropic added the /goal command to Claude Code in v2.1.139. You set a completion condition; the agent keeps working across turns; a second model reads the transcript and decides whether the…

A DevOps engineer posted on r/devops this week with what reads like a familiar shadow-IT question dressed in 2026 clothes. Marketing, product, and sales people across his AI startup are shipping…

Anthropic launched Claude for Small Business on May 13. Every read I've seen has focused on the product surface: 15 prebuilt agentic workflows, 7 named SaaS integrations, a trust posture built…

Carl Frey's recent NYT piece argues that AI's real impact isn't job replacement — it's labor transfer from worker to consumer. We become our own travel agent, accountant, exterminator, doctor. The…

In 2025, four companies — Microsoft, Alphabet, Amazon, Meta — spent over $300 billion on AI data centers. The combined 2026 number is forecast at $725 billion, a 77% jump in a single year. For…

Someone on r/devops just asked whether to take an AWS Cloud Support Engineer role for 18 months — trading hands-on building for "AWS internals exposure and the brand on the CV." Both replies told…

The first time you trim an eval because it costs too much to run, you have started letting the pricing model design your agent. The problem with token pricing for AI is not magnitude — tokens…

A post hit the HN front page this morning titled "I'm going back to writing code by hand". It documents archiving seven months of vibe-coded work on a Kubernetes GPU TUI called k10s and rewriting…

Anthropic asked Claude Opus 4.6 to finish a couplet. Before the model wrote the second line, it had already chosen the rhyme word. We know this because their new method — natural language…

A short post argued this week that reliable agents need deterministic control flow, not more prompts. The argument is correct. The line that lands hardest in the piece is the one about a…

Most AI projects fail somewhere between demo works and production ships. The gap is rarely the model. It's the absence of the controls that turn a one-shot prompt into a system you can run, audit,…

A recent piece called "The Bottleneck Was Never the Code" makes the right argument at the right time. Coding agents shift the constraint from typing to coordination. Organizational context — the…

Last week, a Cursor agent running on Claude Opus 4.6 deleted a startup's production database and its backups in nine seconds. The agent had been asked to fix a credential mismatch in staging. It…

Editor's note (2026-05-16): Lars Faye pushed back in the LinkedIn comments that I mischaracterized his prescription as "type code by hand" — his actual position is periodic abstinence from LLM…

Yanli Liu's "The 4 Lines Every CLAUDE.md Needs" makes a real point. The 4 lines, derived from Andrej Karpathy's January 2026 thread on agent failure modes, all express the same insight: behavioral…

Anthropic now ships at least three different memory models inside the Claude product family, and they don't behave the same way. Claude.ai has a chat memory feature for Pro, Max, Team, and…

Count how many times your agent told you "you're right" today. Count "good catch." Count "I should have noticed that." Now ask yourself how many of those corrections will survive into tomorrow's…

The AI adoption pathway that's actually working in 2026 is not "deploy a copilot to your team." It's "expose your org's context to whichever model your team already chose." That sounds like a…

Microsoft just patched a built-in Entra ID role they shipped as scoped to "agent identities" — and which, in practice, let anyone holding that role take over almost any service principal in the…

The current message from engineering leadership at most companies I talk to is some version of: "find the deterministic automation in your stack and make it agentic." A recent r/devops thread…

Part 2 of 2 on agentic system adoption. Part 1 covered internal adoption: getting your own team to actually use the agent you built. In February 2024, Klarna announced that its AI assistant had…

Part 1 of 2 on agentic system adoption. A 25% bump in individual AI usage correlates with a 1.5% drop in delivery throughput and a 7.2% drop in delivery stability. That's not a hot take — that's…

Since Anthropic released Claude Opus 4.7 on April 16, 2026, a consistent complaint has rippled through developer communities: it feels slower. Threads tell roughly the same story — the prompts…

Anthropic's official plugin directory has 55+ curated Claude Code plugins since launch. The community tracks another 72. By end of 2026, most large engineering orgs will have a private marketplace…

Six frontier coding models now score within 0.8 points of each other on SWE-bench Verified. The same model wrapped in different agent frameworks swings almost ten points on SWE-bench Pro. Picking…

Intercom's Fin AI agent went from $1M to $100M+ ARR on one pricing move: $0.99 per resolved ticket. Not per seat, not per month. Per outcome. Fin now handles 80%+ of Intercom's customer support…

Every week someone posts about AI hallucination like it's a mystery. It's not. A 2025 Frontiers in AI study measured it: vague, multi-objective prompts hallucinate 38.3% of the time. Structured,…

Most AI coding tools ship as monoliths. One big system prompt, one set of capabilities, one-size-fits-all. That works fine for general software engineering. It falls apart the moment you need…

Everyone's writing better prompts. Few are building better context. That's the gap. Prompt engineering treats AI like a search box — craft the perfect query, get the perfect answer. Context…

AWS just launched two autonomous AI agents — Security Agent and DevOps Agent — and they're both generally available now. These aren't chatbots with polished wrappers. They're persistent,…

Everyone's Buying GPUs. Almost Nobody's Ready to Feed Them. The enterprise AI conversation has a blind spot the size of a data center. Every budget meeting I've sat in over the past 18 months has…

The Cloud Repatriation Nobody Expected: Why Enterprise AI Is Pulling Compute Back from the Cloud The original pitch for cloud computing was simple: stop buying servers, rent someone else's. For…

Most enterprise AI projects die quietly. No dramatic failure, no post-mortem email chain. They just... stop. The prototype gets a demo, leadership nods approvingly, and then six months later the…

Addy Osmani dropped a piece last week that's been making the rounds: "Comprehension Debt — The Hidden Cost of AI-Generated Code." His thesis is sharp. Teams are shipping AI-generated code faster…

The Production Gap: Why Nobody Teaches the Infrastructure That Actually Matters Every bootcamp, CS program, and YouTube tutorial series teaches you how to build features. Almost none of them teach…

The AI CapEx Arms Race Is Coming for Your Cloud Bill The three major cloud providers are spending money like it's going out of style. Oracle is financing a $300 billion deal with OpenAI through…

On March 3rd, an attacker compromised the Xygeni GitHub Action by poisoning a mutable tag. Every CI runner referencing xygeni/xygeni-action@v5 quietly started executing a reverse shell to a C2…

The streaming media stack has operated in silos for two decades. Encoding and transcoding happen at the source or in dedicated hardware. Orchestration — ad insertion, CDN routing, audience rules —…

Originally published on the Presidio blog - sharing here as it captures the current reality around agentic AI in enterprise modernization. The pitch behind agentic application modernization is…

Everyone's obsessed with prompt engineering like it's some arcane art. Here's what they're missing: the real challenge isn't crafting clever prompts. It's context management. And most…

Everyone's talking about AI infrastructure like it's the next gold rush. Here's what they're not telling you: most enterprise AI infrastructure projects fail not because of technology limitations,…

In late 2022, I had emergency open heart surgery. Not a metaphorical "rough patch" — my heart literally stopped in the hospital. I coded, was resuscitated, and spent the following months trying to…

The Kubernetes ecosystem just pulled its biggest rug since Docker changed their licensing. Ingress NGINX is being retired in March 2026, and it powers roughly half of all Kubernetes deployments.…

Here's what nobody wants to say out loud: your cloud security posture is probably worse today than it was three years ago. Not because you're doing less—you're doing more. You've deployed every…

Your AI agent project is going to fail. Not because the technology doesn't work—it does. Not because your team isn't smart—they are. It's going to fail because you're building the wrong thing, for…
