[vibhansa-msft]

• Create a github action that starts when a new issue or discussion is created
• Based on title and body, get a responce from DeepWiki
• Parse and filter the output
• Output might be very large in nature, so summarize it using a hugging face model
• In case of issue post the short summary and details.
• In case of discussion only post the details.
• PR also contains a github action that runs on 1st of every month and iterates through all the PRs and Issues of this repo. It then converts everything into a text file and files a PR uploading those files. This is important to train any model on our repo having access to not only code but also our past issues and PRs.
