Three Google products, one project — what worked, what didn't, what I'd change
Heat Protein Lab was a deliberate composability test — build a citation-grounded scientific explainer using Antigravity 2.0, Google DeepMind's Science Skills bundle, and Stitch in concert, by one indie developer at a kitchen table, in a small number of sessions. This is the post-mortem on the tools: what worked, what didn't, the agy --print CLI stall, the API-key-in-scratch hazard, three upstream science-skills bugs filed, and two docs-PRs I would open next if I had the time.
