Logbook

Notes from the workshop.

Long-form posts on what we built and what we learned. Mostly retrospectives, because retrospectives are the genre of AI writing worth reading.

• Mission · Cuppa Harness

  Cuppa Harness: the pattern library for the model-churn era

  Why we extracted the harness layer from a shipping iOS app — and what's in it. Protocols, memory patterns, orchestration, output repair. Six surfaces, each one a thing we got wrong before we got it right.

• Mission · cuppa.studio

  cuppa.studio: where a prompt becomes a presentation

  The mission behind cuppa.studio — an AI-native online IDE that closes the gap between YouTube tutorials and dense reference docs. Markdown in, animated narratable slides out, in seconds.

  From @mycuppa/* to Cuppa Harness: what survived

  A V1 R&D retrospective. Six AI components we shipped under the @mycuppa/* line — what graduated to Harness, what was premature (the MCP skill registry bet), and what quietly became cuppa.studio.

More retrospectives queued — decoder permissiveness, the extraction diary, the V1 cross-platform postmortem.
