You can now see a breakdown of your agent’s context usage!
Click on an agent’s context ring to see how much context is going to rules, skills, MCPs, subagents, and more. This is super useful for spotting when a bucket looks heavier than you’d expect and tightening your setup.
I am a huge fan of this feature 
For some reason it didn’t work for me (clicking the ring in neither editor window nor agent window did anything), until I sent a message in the agent window for the first time (which enables this feature for both the editor window and the agent window). Edge case bug?
Hey @User670839245!
I think the behavior is that you must have sent a chat with v3.3 before you can see this information. After sending a new message, it will work for that chat. Is that what you’re experiencing?
More specifically, I needed to send a chat specifically in the agents window before I can see the context breakdown. I’ve sent plenty of messages in the IDE window.
This is great but it would be further improved if you could drill into each category to see which specific items were contributing to the context usage. For example, context usage by MCP server (and potentially drill into MCP server to see by tool), context usage by rule file/name, context usage by skill.
Without this granularity it is a little difficult to identify particular context that could be reduced. Claude Code /context has provided this granularity for quite some time, I think it would be great to add to Cursor and your version will ultimately be better because it will be visual AND interactive (drill in).
100% this. That was kinda the beauty of the previous interface you could at least see a few of the rules that were being pulled in. If we could click into at least the rules and skills to start that would be awesome
Nice feature. Could we have documentation on what items contribute to each category? Seems no updates about doc site talking about this.
