Ask ten teams if they’ve built an AI agent and nine will say yes. Look at what they actually shipped and most of it is a workflow with one LLM…
There are a hundred “AI concepts explained for beginners” listicles, and most of them are written for people who will never build anything. This one isn’t. If you’re a data…
A team I worked with upgraded their support-ticket triage pipeline to a bigger, newer model expecting fewer mistakes. Benchmarks said it was smarter across the board. Two weeks in, the…
The Slack message came in at 9:14 on a Tuesday: “why is yesterday’s Snowflake bill $4,200 over budget and who approved it.” Nobody had approved anything. A dashboard refresh job…
A support-triage agent I built last quarter had read access to our CRM, could issue refunds under $50 without approval, and could send email on a customer’s behalf to confirm…
Two weeks ago, an agent I run locally for pipeline maintenance rewrote a retry handler using a flat, fixed-delay retry. It looked reasonable. It was also the exact pattern that…
A team I advised shipped their first AI-generated pipeline on a Thursday. An agent had scaffolded a dbt model from a plain-English request — “roll daily revenue up to weekly…
Processing millions of food records taught me that data quality is rarely one clever cleaning function. It is a chain of small contracts: what a number means, which identifier owns…
I watched an engineer lose the better part of a day to a “top MCP servers” listicle. He wired his agent to a standalone Postgres server and a Puppeteer server…
A team I know left a coding agent running on a Friday afternoon. The task was open-ended — “keep fixing failing tests until the suite is green” — and the…
Three weeks ago I watched a teammate open the OpenAI billing dashboard and go quiet. We’d built a PII-tagging job that ran a small classification prompt against every new row…
A colleague pinged me last spring, quietly furious. He’d spent three days building an MCP server to give an internal agent access to the team’s Snowflake warehouse. The protocol part…
Every data platform team building agentic pipelines hits the same wall eventually. You want Claude or CoCo to query Snowflake, trigger a dbt run, check an Airflow DAG, and post…
The incident report blamed the model. “The agent called the delete endpoint twice and wiped a partition it shouldn’t have touched.” Everyone nodded, someone filed a ticket to “upgrade to…
A data engineer I know spent three weeks building a “multi-agent data quality system.” It had an orchestrator agent, a profiling subagent, an anomaly-detection subagent, and a remediation subagent,…
The question came up in a Slack channel for a platform team I was advising: “We want to give our AI coding agent access to the pipeline metadata so it…
The bug report said: “The model is broken. It gives a different answer every time I ask the same question.” I’ve gotten some version of this from three different engineers…
Your AI agent isn’t getting dumber over time. It’s getting amnesiac. It forgets a constraint you set ten turns ago, even though it followed it perfectly at turn three. It contradicts…
Most developers are using Claude Code like a fancy autocomplete. Paste a bug, get a fix, repeat — never building on anything. This guide covers everything that separates that from…
