About bugzero
An AI agent that analyzes production errors from Sentry and opens GitHub pull requests with fixes, automatically. Connect GitHub and Sentry in about two minutes, OAuth and a GitHub App, no webhook wrangling. The agent analyzes the error and shows the fix it would make, but opens no PR until you approve it.
About underfoot
Apple and Google swap the AI models inside your phone with OS updates. underfoot freezes one prompt suite, captures every OS build's answers, and publishes exactly what moved. Once a build is superseded, its model can never be measured again: every trace below is history that cannot be re-taken. All 140 macOS runs succeeded and every prompt returned byte-identical output across its 5 greedy runs, including the creative canaries (the haiku never varied). Any future change on this platform is the OS's doing, not sampling noise.
