Where does the bug appear (feature/product)?

Cloud Agent (GitHub, Slack, Web, Linear)

Describe the Bug

If I’m working locally, the summarize skill is working, but if I work on a cloud agent, the summarize skill just does nothing after entering it.

Steps to Reproduce

Start a cloud agent, enter some prompts, and then do a summarize in a separate prompt.

Expected Behavior

It should shorten the whole conversation and the context window should be almost empty.

Operating System

Linux

Thanks for the report, @nerumo! This is a known issue with Cloud Agents. Automatic summarization still works as expected, but the /summarize command currently only works for local agents. I’ve added your feedback to the issue where we’re tracking this!
