What This Skill Does
OpenCal is a calorie and nutrition tracker with an iOS app. This skill lets an AI agent log meals, retrieve daily intake summaries, and update calorie or macro goals by calling the OpenCal API directly. Users describe what they ate in plain language and the agent handles search, scaling, and logging.
Lets users track food without opening the app — a single message logs a meal end-to-end, including portion scaling.
When to use it
- Logging a meal by describing it in conversation
- Checking remaining protein or calories for the day
- Reviewing everything eaten so far today
- Correcting or removing a mistaken food entry
- Updating a daily calorie goal before starting a cut
