I made `git push` refuse to work until I touch grass

说明与用途

一个 Git pre‑push 钩子，要求开发者在推送前先到户外走走，使用本地 Gemma 4 模型验证外景照片。

问题

Developers lose track of time and neglect breaks while coding, leading to burnout and reduced productivity.

结果

The tool achieved 18/18 correct classifications on a 18‑photo benchmark, blocking fakes and encouraging short outdoor breaks before code pushes.

工作流

• 1. Run touchgrass install to add a pre‑push hook.
• 2. After the configured time indoors, git push is blocked and shows a QR code.
• 3. Run touchgrass prove to start a local or tunneled web page that opens the rear camera.
• 4. Capture a photo of an outdoor scene within 15 minutes of capture time.
• 5. The photo is sent to Gemma 4 via Ollama for analysis.
• 6. The script evaluates the model’s JSON output for outdoors, sky_or_plants, and no screen.
• 7. If all checks pass, the hook resets the timer and allows the push; otherwise the push remains blocked.

After 3 hours indoors (you can change that), this happens. Here's a real one from testing, with the limit set to 1 minute:

来源

The first run got 16 out of 18. Every real photo was right. Both fakes sailed through as "Grass confirmed"

Second run: 18 out of 18, about 26 seconds a photo on a 4 core CPU with no GPU.

来源

The photo goes to Gemma through Ollama, on localhost.
