Where does the bug appear (feature/product)?

Background Agent (GitHub, Slack, Web, Linear)

Describe the Bug

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 ?

Does this stop you from using Cursor

No - Cursor works, but with this issue

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.

More details here: Cloud agents with environment.json can't use computerUse subagent (via the Task tool). Same issue, and this workaround is confirmed.

The team is aware. Let me know if the workaround helps.
