I build tools for agents that work with code, design, and running systems.
Agents can generate changes quickly, but they still need good feedback to verify the result. My work exposes structure around software artifacts — design trees, visual diffs, code ASTs, runtime state, build graphs, checks, replay, and feedback loops — so agents can inspect, modify, and correct their work more reliably.
It is one project, not many: a web stack where AI-generated software can be checked — every failure carrying its location and cause, every session replayable, every dependency traceable. The thesis, the architecture, the roadmap, and the honest uncertainties are maintained as a living standard: Building Blocks for the Future Web.
