Done. Here’s what was added:

New file: ww/weather/rain.py

• Records 3s video from webcam via ffmpeg (avfoundation)
• Extracts 5 frames (1 per second)
• Sends all frames to vision model (VISION_MODEL or MODEL from .env) via OpenRouter
• Rates rain on a 0-5 scale with detail and advice
• Designed for in-car use: prompt tells the model the webcam faces the windshield, window may be closed

Usage:

ww rain              # 3-second video, analyze rain
ww rain --seconds 5  # longer capture
ww rain --keep       # keep the video file
ww rain --debug      # show model/request info
ww weather rain      # also works

Files modified:

• ww/main.py — routing for ww rain (top-level) and ww weather rain, help text, all_groups
• ~/.zsh/completions/_ww — rain in top-level commands + weather_cmds array with rain subcommand

How it works in the car: Point the laptop webcam at the windshield. Run ww rain. It captures a short video, extracts frames, and tells you the rain intensity (0=clear to 5=torrential) with a practical advice line like “close window” or “safe to open window slightly”.
