I'm a fullstack developer (Flutter, Nuxt, Spring Boot) writing about agentic coding in practice: how I build software with AI agent teams in Claude Code and GitHub Copilot — what works, what breaks, and what it costs.
None of it is theory. The AI agents work on my real projects — Flutter apps like Atomin, the habit tracker I built and ship, and Nuxt web apps like this blog. Every post comes from code that actually goes to production.
Alongside the agentic coding series you'll find my products, project write-ups, and tutorials on web and mobile development. Start with the blog, or take a look at what the agents and I have built so far.

After the switch to AI credits, I hit my limit fast. How a local setup of Qwen3.6-27B, OpenCode, the Language Server Protocol and CodeGraph got me back up to speed – and saves 69 % of tokens according to CodeGraph's own benchmark.

Agent files grow with every project. How I move recurring specialized knowledge into Agent Skills, what progressive disclosure actually saves – and why more skills don't automatically mean better agents.

Which risks can arise from using AI agents in the development process? An honest look at skill atrophy, cognitive debt, hidden costs – and why the problem is real, but perhaps temporary.

Which metrics can be used to measure the positive effect of AI agents in the development process? My approaches to agent performance measurement.

How I integrate Figma and Appwrite MCPs into my agent workflow to cleanly connect frontend and backend without manual translation.

Two ways to your own agent team in Claude Code and GitHub Copilot – adapt ready-made templates or build from scratch with /agents or /create-agent. Plus the trick for translating a Claude template into a Copilot-compliant variant via GitHub Copilot.

A concrete walkthrough through all five phases of the agent team – from the first vague feature wish to a tested commit. Including the real handoffs, the checkpoints, and the moment where I had to correct the agents.
06/08/2026
Why a green build doesn't mean a feature works – and how a fifth, specialized agent turns the use case into an executable end-to-end test, closing the loop back to the original requirement.
06/01/2026
How an atomic battle plan and a focused Developer Agent close the gap between concept and code – and why Human-in-the-Loop works differently here than in the planning phase.
05/25/2026
How two specialized AI agents steer the planning process in the right direction through Human-in-the-Loop checkpoints – and why that matters more than pure speed gains.

Why simple prompting and "vibe coding" fail on complex projects – and the four systemic problems that forced me to rethink my entire development workflow.

My approach to improving code quality when using AI coding assistants through the use of copilot-instructions.md and AGENTS.md files.
