I use the onboarding feature to create a new environnement (it needed docker, docker-compose, IP Whitelisting for DDB etc..).
It successfully created the AGENTS.md, when I create a new env from this snapshot it instantly success with no new edition to the AGENTS.md.
However, when I just open a new agents for a small “feature” nothing is mounted, the “Desktop” part remains empty.
Steps to Reproduce
Described above
Expected Behavior
I guess when I prompt an agents it is supposed to automatically mount an env so that I can preview in the “Desktop” tab ?
Hey, thanks for the report. This is a known issue. Computer use works during the initial environment setup, but on later agent runs the system doesn’t recognize the environment as testing-capable, so the Desktop tab stays empty.
Workaround: delete the environment.json file from the .cursor/ directory in your repo. After that, the dashboard config should get picked up, and computer use should work in new agents.
I see that environment.json isn’t there, so that workaround really doesn’t apply. Sorry for the confusion.
One more thing. You mentioned you’re using Composer 2 for new agents, but you created the environment on Opus 4.6. There are confirmed cases where computer use (the Desktop tab) doesn’t work with Composer family models, here’s a thread with the same conclusion: Computer use cloud agent snapshot not applied.
Try starting a new agent on Opus 4.6 (or another non-Composer model) and check if Desktop shows up. Let me know if that helps.
