What is Apple Calendar CLI (accli)?
The Apple Calendar CLI (accli) is a powerful tool designed for macOS users to interact with their native calendar application directly from the terminal or through automated agents. As part of the Openclaw Skills ecosystem, it allows AI agents and developers to list calendars, query events, and manage schedules with precision.
It leverages JavaScript for Automation (JXA) to provide a deep, native integration with the macOS system. By using this skill, users can bridge the gap between their local calendar data and automated AI workflows. This Openclaw Skills integration is perfect for those who want to automate their daily planning, sync schedules, or build custom productivity tools without leaving their terminal environment.
Apple Calendar CLI (accli) Use Cases
- Scheduling meetings and events via simple text prompts to an AI agent.
- Checking daily availability and free-busy slots across multiple macOS calendars simultaneously.
- Automating calendar cleanup by deleting or updating outdated events.
- Fetching agenda summaries for specific projects or date ranges using case-insensitive search queries.
How Apple Calendar CLI (accli) Works
- The user or AI agent invokes the accli command to list available calendars and identify the correct persistent IDs.
- The tool queries the macOS Calendar database using native automation protocols to retrieve events or check availability for specific time ranges.
- Based on the output, the user can create, update, or delete events by passing parameters like summary, start time, and location.
- The skill returns structured JSON data for every operation, allowing for programmatic parsing and sophisticated logic within the Openclaw Skills framework.
Apple Calendar CLI (accli) Setup
To get started with this skill, ensure you are on a macOS machine and run the following command to install the CLI globally:
npm install -g @joargp/accli
After installation, you may need to grant your terminal or IDE the necessary permissions to access Calendar data in macOS System Settings. You can verify the installation and set your default calendar by running:
accli config set-default
