This was a weekend experiment to see what is possible with long horizon agents, which is the pattern of using role-based agents on top of some sort of task store.
As someone who has taken on-call rotation and maintenance work at many a startup, this is the pattern that I would have liked to have had.
Fun to build and would certainly do so again next time I'm doing a production-ready build. Would be exciting to add product analytics having the agent do minor feature work too, with it's own A/B testing of the results.
