I’m not sure if this is a feature of Cursor, but it keeps showing “100% context used” even after I switch to a new chat, and it continuously triggers context summarization.
Hey, from your screenshot I can see the context indicator in a new chat immediately shows 100%.
A few questions to narrow down the cause:
Does this happen with all models, or only in Auto mode?
Can you reproduce it every time you create a new chat, or only sometimes?
Can you share a Request ID from one of the affected sessions? Three dots in the top right of the chat > Copy Request ID
Also, please try a quick test: open a completely new chat in a different project (or in an empty folder) and see if the context still shows 100%. This will help confirm whether something from your project context is being pulled in right away, like large files, rules, and so on.
The team is aware that the context indicator can sometimes show incorrect values. Your report and the Request ID will help us prioritize.
Hey, thanks for the Request IDs and screenshots, super helpful.
To answer your request, yes, having a lot of globally enabled skills can fill up your context window right from the start. Skills, rules, and MCP tool definitions all get loaded into context when you open a new chat, even in an empty folder, since global skills apply everywhere.
Can you check this:
Go to Cursor Settings > Rules, Skills, Subagents > Skills and count how many global skills are enabled. If there are a lot, try disabling them temporarily and start a new chat to see if the context indicator goes back to normal.
Do the same for global rules. Check if you have a lot of large .mdc files in ~/.cursor/rules/.
Do you have any MCP servers configured? Those tool definitions also take up context.
Since it reproduces in an empty folder but still shows 100%, it strongly suggests something global is using up all the context before you even type anything.
