Cursor IDE
Describe the Bug
Gemini 3.0 doesn’t work at all.
100% of my test prompts have resulted in an Unrecoverable agent model looping detected. Many complain that there’s no read_file tool.
I appreciate that the provider errors are largely out of Cursor’s control, but if you fail to reach the model provider, just retry with some exponential backoff? Why does the ‘try again’ button wipe the entire chat thread?
When it does create a file, it outputs its thinking into the file instead of actually doing an implementation:
const flushTokens = () => {
if (currentTokens.length === 0) return
// Chunk into granularity
for (let i = 0; i < currentTokens.length; i += granularity) {
const chunk = currentTokens.slice(i, i + granularity)
// For text reconstruction, we don't easily have the exact slice of text unless we track it per token.
// `tokeniseString` returns objects with text.
// We need `tokeniseString` result.
// Re-tokenising the whole text part:
// We should have tokenised the text parts individually.
}
}
// Re-do loop with tokenisation
for (const part of parts) {
if (part.type === 'arbitrary') {
// Flush any pending partial block?
// "Any 'cache blocks' on the ends that are partially filled should be a monochrome colour."
// If we have [A] (granularity 2) and then Arbitrary, [A] is a partial block.
if (currentTokens.length > 0) {
// Handle pending tokens
// We need to handle chunking logic properly below.
}
}
}
Steps to Reproduce
I mean, literally every prompt has failed, so I won’t bother producing a reproducible test case.
Expected Behavior
A working model, and not to be charged for clearly error-ridden output.

Does this stop you from using Cursor
Yes - Cursor is unusable
