Since spring 2026, two projects have been taking shape with the same coding agent: an ETL generator on Next.js and PostgreSQL, and this blog. The agent does not complete lines, it works through assignments in the repository. This article collects my agentic coding experience from a user’s perspective. I build databases, ETL processes and the … Read more
The conventions were settled: procedure skeletons, DECLARE banners, file naming, forbidden constructs — all versioned in rule files, every rule with its rationale. The only open question was which tool should check the SQL conventions. And the first reflex was the same one that probably surfaces in every Postgres team with convention ambitions: “Just use … Read more
There is a moment when a CLAUDE.md tips over. That moment does not sit on any calendar, it shows in behavior: the file keeps getting longer, and the rules inside it keep getting followed less. Every new convention you write in dilutes the ones already there. That is exactly where the project behind this article … Read more
It didn’t start with an audit. It started with a nagging feeling: the interface looked restless. You don’t notice it at first glance, but on the second and third look it is there — a timestamp slightly larger here than there, a dialog title a touch smaller than in the neighboring dialog. Everyone knows the … Read more
“You spend more time with her than with me.” That’s a sentence you usually hear when an affair comes to light — in my case, it was about Claude Code. And suddenly there was a question in the room I had never thought about before: Is Claude actually a woman or a man? What this … Read more
An empty repo and Claude Code, Anthropic’s coding agent in the terminal — that’s all it takes to get going. And that is exactly the problem: the model writes code immediately, but by default nothing ensures that a specification exists first, that a review happens afterwards, or that the database schema deploys reproducibly. A Claude … Read more
Every new project starts with the same ritual: create an empty repo, then hunt down the folder structure, the conventions and the workflow files from the last project — and forget half of them. A Claude Code project template can invert that reflex: instead of starting with nothing and building up piece by piece, you … Read more
Inside a Claude Code project’s .claude/ folder, rules and skills sit side by side: Markdown files that look almost identical — and behave in exactly opposite ways. That contrast is what Claude Code skills vs rules comes down to: rules are fully in context at every session start; a skill costs next to nothing until someone invokes it. Get … Read more
The schema is done — now what? The reflex answer is Flyway or Liquibase. But for a small, database-centric project, a migration tool is often more machinery than the task calls for: its own version table, a runtime dependency, a file format you commit to. There is another way. Deploying a Postgres schema without a migration … Read more
A view is the most elegant way to encapsulate a recurring query — right up to the moment the query needs an argument from outside. A view has no parameters. As soon as a value belongs in the WHERE that the caller supplies, the table-valued function is the tool of choice: a function that returns an entire result set … Read more
