Same brief, two toolchains — heat-metrics-lab vs heat-protein-lab

Two days after heat-protein-lab shipped on Google's stack (Antigravity 2.0, Stitch MCP, DeepMind Science Skills), I built the same class of artifact on the Anthropic stack (Claude Code, advisor, tufte-viz, subagent-driven-development, session-report). Both produced a 9-chapter scrollytelling explainer deployed to Cloudflare Pages. The session-report telemetry shows heat-metrics-lab cost 2.7× fewer tokens. The Anthropic side caught two pre-ship bugs that the Google side had no equivalent gate for. The Google side still has the clearest single advantage — Science Skills' structured domain data — and no Anthropic counterpart today.

Heat Protein Lab is live — what eight Antigravity sessions taught me about scientific UI

Heat Protein Lab is now public — eight chapters of scrollytelling about what heat does to human proteins, each anchored on a real protein with a real structure file, citations back-linked to PubMed, tissue claims sourced from the Human Protein Atlas, no analytics, no medical claims. This is the full ship retrospective: the chapters table, the phase-by-phase build log, what shipped vs what was cut, page weight, the Celsius/Fahrenheit toggle that landed two hours before publish, and what I would do differently if I started over.

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.

Visualizing what heat does to a protein, without running molecular dynamics

Chapter 4 of heat-protein-lab is the visual centerpiece — a real human enzyme (aldolase A, PDB 6XMH) that falls apart on the page as the reader scrolls. It is also the chapter most likely to mislead. This post is about how I drew the line in code between educational visualization and fake science: three discrete 3Dmol style stages (cartoon → ribbon → wireframe), atoms that never move, a VISUALIZATION-NOT-MOLECULAR-DYNAMICS badge pinned above the heading, and a readout panel with deliberately fuzzy quantities.

Wiring 17 scientific skills into a fresh Antigravity workspace

The story I should have told at the Google I/O 2026 hackathon — and didn't, because making any claim about human biology under a 48-hour deadline is asking for trouble. Two days later I started the repo it should have been: heat-protein-lab, an explainer of what heat does to human proteins, built in Antigravity 2.0 against Google DeepMind's Science Skills bundle. This post is Phase 0 — wiring seventeen scientific skills into a fresh workspace, with three lessons that fell out the other end.

Meeting HSF1 in Antigravity 2.0 — the first chapter shipped

The first chapter of heat-protein-lab is live. It introduces HSF1, the protein your cells use as a thermometer — rendered from a real PDB structure, citations pulled live through Google DeepMind's Science Skills bundle, tissue expression from the Human Protein Atlas across 49 tissues. This post is Phase 1, with three things worth a post on their own: a scientific correction the verification step caught (5D5W vs 5D5U), the build pattern (plain HTML/CSS, no bundler, gzipped mmCIF decoded in-page), and what the agy CLI stall taught me about prompts.

Heat Threshold at the Google I/O hackathon — overbuilt a lot of things

On 2026-05-23 at Shack15 SF, against a field of 152 submissions, I built Heat Threshold (HeatThreshold/HeatThreshold) at the Cerebral Valley × Google DeepMind I/O hackathon. The dashboard, the WebXR Spatial HUD, the Gemini Live ↔ Managed Agents voice bridge, the trace/record/replay observability stack — all 100% new code shipped in the seven-hour window. The submission video, the demo URL placeholders in the README, and a compelling three-minute story were the things that didn't ship. This post is the retro, anchored to the public X thread under @CraigMerry.
