it feels like gemini is the only model that gets stuck because it cant read more than 250 lines of any file. i tried putting the context file in the prompt and putting it in the rules to read FULL files instead of the first 250 lines. doesnt work..

That is the cap on the native read file tool in Cursor, if you want to go beyond the 250 line limitation then you will need to use a custom MCP tool.
See the link below for a suitable one that will meet your request:

add this to your rule:
- **Handle Tool Limitations & Multiple Calls**: Recognize that tools like `read_file` might only show a portion of the code at a time. If the information is insufficient, **do not hesitate to call `read_file` again** to read other parts of the file (adjacent code blocks, imports at the top, exports at the bottom, etc.), or adjust the reading range. **Specifically, when the tool fails to return the complete file at once due to limitations (even if requested), proactively use line range parameters (`start_line_one_indexed`, `end_line_one_indexed_inclusive`) to read the remaining content in segments, ensuring complete context acquisition.** Combine with other tools (like `grep_search`) for more comprehensive information.

This is also a viable option, unless you’re working with monolithic files that require 4+ tool calls.. which you should modularize if that’s the case.
The MCP tool I provided also gives the ability to read multiple files at once as well, plus some other various convenient tools.
