Get errors and warnings for the project or a specific file.

This tool can be invoked after a series of edits to determine if further edits are necessary, or if the user asks to fix errors or warnings in their codebase.

When a path is provided, shows all diagnostics for that specific file. When no path is provided, shows a summary of error and warning counts for all files in the project.

To get diagnostics for a specific file: { "path": "src/main.rs" }

To get a project-wide diagnostic summary: {}

IMPORTANT: When you're done making changes, you MUST get the project diagnostics (input: {}) at the end of your edits so you can fix any problems you might have introduced. DO NOT tell the user you're done before doing this!
