A framework gives you a callable agent. The harness is everything that happens next. After building one on top of Microsoft Agent Framework, six pieces stand out — notes on each, and what they contribute.

If the working method is AI-assisted, the learning method should be too. Notes from rebuilding Claude Code on Microsoft Agent Framework.

I have been shipping faster than ever with AI. That is exactly what made me stop and check how much I was actually verifying.

I keep rebuilding the same thing: a live HLS stream with the UTC clock on every frame. Player latency, recorder cuts, EPG flips — all obvious when you can just read the timestamp.

Built it from scratch twice. Third time I made a repo.

Prompting is what you do at the start. Steering is what you do in the middle.

Caching a geo-restricted app sounds messy. 200 country codes, 200 cache entries, hit rate falls off a cliff.

The trick: cache by *what they see*, not *where they are*. Hash the set of regions a country resolves to. ~12 buckets instead of 200. Same hit rate, same correctness.

Today is Children's Day in Turkey. As parents caught in the AI wave, we keep hearing: "We got by somehow — but what will our kids do?"

Built a one-command setup that puts Claude Code on its own server. It picks up Linear tickets, writes code, opens PRs — no laptop required. Wrote about what broke along the way.

@mattpocockuk I mostly code on .NET and use the ABP framework, which applies DDD principles nicely. A similar opinionated framework in your stack might speed things up.

[Rupen Melkisetoğlu @melkisetoglu]

New flow I'm testing: Linear → Local Cyrus → Claude Code → GitHub.

Still figuring out where reviews fit vs just leaning on TDD.

Anyone else getting lost in the review step, or is TDD the real answer here?
