Summary

A developer created a web-based tool that automatically generates Cursor rules by crawling documentation websites to help LLMs better understand new or updated libraries. The tool specifically addresses the challenge of LLM knowledge cutoffs for newer technologies like Svelte 5 and Cloudflare Workflows, producing customized prompts that can be selectively applied in Cursor's rule system.

Prompt

Generate Cursor rules for [LIBRARY_NAME] that include:
1. Latest API documentation and usage patterns
2. Common implementation examples
3. Best practices and gotchas
4. Version-specific features and changes
The rules should be formatted for .cursor/rules and focus on practical code completion and assistance scenarios.

Best Practices

Modular Rule Organization

important

Separate Cursor rules for different libraries into distinct files

Documentation-Based Rule Generation

critical

Automatically generate rules by crawling official documentation

Common Mistakes to Avoid

Avoid Direct Rule Implementation Without Documentation

important

Don't create Cursor rules without referencing official documentation

Don't Rely on Generated Rules Without Review

important

Avoid using automatically generated rules without manual verification
