[solution]

Gets text content for a file under the loaded root, with optional line-window limits. Supports files outside the loaded C# project model when they are still inside the loaded root.

Why this tool exists

Sometimes the right evidence is still a bounded line window from a real file.

How it helps the agent

The model can inspect exactly the slice it needs while staying under context budget.

Parameters

Name	Type	Required	Description
filePath	string	Yes	File path to read. Can be absolute or relative to the loaded root.
startLine	number	No	Optional 1-based start line. Defaults to 1.
endLine	number	No	Optional 1-based inclusive end line. Defaults to the end of the file.
maxLines	number	No	Maximum number of lines to return. Use 0 for unlimited. Default is 400.
maxChars	number	No	Maximum characters to return. Use 0 for unlimited. Default is 100000.
pathStyle	string	No	Path style: 'absolute' (default) or 'relative' (to solution root).
