Harnest prepares the environment automatically. Open http://127.0.0.1:1907/ to chat with your agent in the playground.

​
Choose a starting size

Append one of these flags to harnest init, or keep the default.

​
Add a scheduled function

From the project directory, create a cron function with its own queued task:
Implement the generated cron/daily_report.py and configure shared task and cron storage before serving. For a target whose schedule is created at runtime, use harnest add cron reminder --dynamic. See scheduled tasks for setup and dynamic schedules for runtime control. Explore the project structure · Add Agent Tools · Configure serving
