We have been doing something similar but it sounds like you have come further along this way of working. We (with help from Claude) have built a similar tool that you describe to interface with our task- and project management system, and use it together with the Gitlab and Github CLI tools to allow agents to read tickets, formulate a plan and create solutions and create MR/PR to the relevant repos. For most of our knowledge base we use Markdown but some of it is tied up in Confluence, that's why I have an interest in that part. And, some is even in workflows are in Google Docs which makes the OP tool interesting as well -- currently our tool output Markdown and we just "paste from markdown" into Gdocs. We might be able to revise and improve that too.
For open source project management tools I prefer to use the integrated solution from Phabricator[1], nowadays called Phorge[2]. It has workboards, very good access control and separation of projects (tags). See an example board[3].
