Let Codex build an app sharing Android health data

An Android user was jealous of iPhone users who connect Apple Health to ChatGPT, and asked Codex to build an app and an MCP server for Health Connect. By his estimate it took four to five prompts, and the app now syncs his data. The code is shared openly. The post says nothing about how the health data is protected, so read the code before you use it.

Build an Android app and an MCP server that read [data types] from Health Connect and make them available to [assistant], for me only. The data should be stored in [place], and nobody else should get access. Write down what the app asks permission for. Do not send data anywhere before I have read the code. You are done when the app has synced one test record and I have seen where it is stored.

Find what slows your websites down with parallel agents
A developer pulled out which pages used the most server time over the last day, then set four Grok agents to work, one per site. Each agent first took a baseline and tested three possible explanations. In 20 minutes they found and fixed, among other things, a database query that went from 550.7 to 0.45 milliseconds and a page that went from 228 to 11. He has shared the setup as open source.

Move old research code to a safer language with agents
From Google, the company behind Gemini. According to Google, an agent in Antigravity moved the core of a 174,774 line Fortran and C ocean model to Rust in 59 minutes. It first recorded the original's output across 100 random runs, then planned all 264 files and rewrote the code. It found six old bugs, and the new code ran 1.88 times faster using about half the memory. The figures are Google's own.
