### Motivation and Context This PR ports the plan object model found in the .NET SK to Python. This fundamentally changes the concept of a planner from a `semantic skill` to a unique type of `SKFunction`. With this model, we can begin implementing sequential planner and offer much better plan customization. **Notes:** - This PR does not implement plan serialization/deserialization to/from JSON. There is a huge existing effort to make the Python SK completely Pydantic enabled, which will bring serialization and deserialization capability with it. - This PR does not include ports of `Action Planner` and `Sequential Planner` to the Plan Object Model (POM). Following PRs will address this. - I also added some missing copywrite headers. A future PR will add headers to any still missing them. - added a VSCode launch configuration to run the current file with pytest - closes #1486 ### Description - Added file called `plan.py` which is a python port of the Plan.cs file found in the .NET SK. Note that it does not contain serialization logic at this time. - Added new kernel error `FunctionInvokeError` - mirrors the error list of the .NET SK - Added tests for Plan creation - Added tests for Plan execution - both sync and async ### Contribution Checklist <!-- Before submitting this PR, please make sure: --> - [ ] The code builds clean without any errors or warnings - [ ] The PR follows SK Contribution Guidelines (https://github.com/microsoft/semantic-kernel/blob/main/CONTRIBUTING.md) - [ ] The code follows the .NET coding conventions (https://learn.microsoft.com/dotnet/csharp/fundamentals/coding-style/coding-conventions) verified with `dotnet format` - [ ] All unit tests pass, and I have added new tests where possible - [ ] I didn't break anyone 😄 --------- Co-authored-by: Shawn Callegari <[email protected]>
