AI assistant gets stuck in search/read loops with high token usage and no timeout #9923
Description
Plugin Type
VSCode Extension
Cline Version
3.75.0
What happened?
The AI assistant repeatedly uses search_files and read_file tools in loops, consuming high token usage without making progress on the task, and doesn't timeout properly. Expected behavior is for the AI to complete tasks efficiently without getting stuck in repetitive tool usage.
Steps to reproduce
- Start a task that involves reading a large HTML file (like GoblinAnimationCompleter.html)
- Have the AI search for specific functions or code patterns
- The AI begins repeatedly reading the same file sections and searching for the same patterns without making progress
- Token usage increases significantly (up to 100% context usage observed)
- The AI does not timeout or break out of the loop

Thanks for reporting this. PR #9933 was just merged — it adds detection for repeated identical tool calls, which should catch the search/read loop pattern you described. Expect the fix in the next release. Feel free to reopen if you still see it after updating.
