How does it find patterns in my project?

The skill uses a combination of Grep for local file searching, file globbing, and content analysis based on a pre-defined reference list of common Rails conventions.

Does it support custom Rails patterns?

Yes, it uses a reference.md mapping that allows it to understand various naming conventions and directory structures specific to your Rails application.

Can it suggest community best practices if my project is empty?

Yes, if a pattern is not found locally, the tool provides best-practice examples from external sources and curated documentation to help you start with the right structure.

Which MCP tools are recommended for this skill?

While it works with standard tools, it is optimized for use with context7-mcp, ref-tools-mcp, and tavily-mcp for more efficient documentation and pattern searching.
