Sounds like Duet is more like Grokbot than Muse? Haven't used it but the author is talking about channels, github policy access for specific channels, etc. That doesn't sound like the Muse use case.

I actually use Claude's agents on the Claude platform for all things work related and it works pretty well. It's not cheap though if you use the more expensive models and setting it up requires currently some initial effort for connecting integrations like Slack the average user is unlikely to do. It also doesn't let you change things. Every change requires a new deployment. As a cloud agent that runs on a schedule it's pretty good. I think they just need to figure out a single place for this. Currently you can set up agents on the claude platform, as part of claude code, and as part of regular claude.
