 If you want to run the tests for a single package, you can use the `uv run poe test` command with the package name as an argument. For example, to run the tests for the `agent_framework` package, you can use:
 
 ```bash
-uv run poe --directory packages/main test
+uv run poe --directory packages/core test
 ```
 
 These commands also output the coverage report.
