task-sync
This skill synchronizes TickTick and Google Tasks bidirectionally, includes setup scripts and an end-to-end test suite. It reads/writes OAuth tokens (`config.json`, `data/google_token.json`, `data/ticktick_token.json`), makes network calls to `https://api.ticktick.com/open/v1` and Google Tasks, and runs `python sync.py` via subprocess/cron.
