Cozi Skill

Unofficial client for Cozi Family Organizer API. Manage shopping lists and todo lists.

⚠️ Important: This uses an unofficial API (reverse-engineered). Cozi may change it at any time.

Environment Variables

Set these in your agent's .env (~/.openclaw/.env) or create a skill-level .env at ~/.openclaw/skills/cozi/.env:

COZI_EMAIL — Your Cozi account email
COZI_PASSWORD — Your Cozi account password

The script only reads COZI_EMAIL and COZI_PASSWORD from .env files — other variables are ignored.

Session Caching

The script caches your session token in ~/.openclaw/skills/cozi/.session.json to avoid re-authenticating every call. Tokens expire — it will re-auth when needed.
