WHY IT NEEDS A POLICY

Why fix_markdown_file needs a policy

Despite the empty description, the tool name strongly suggests it modifies markdown file content. In the context of a Windows file operations server, this is a Write operation—it creates or modifies data reversibly. Severity is medium because unintended markdown modifications could corrupt documentation or configuration files, but the changes are typically reversible via version control or backups.

From the tool's definition Tool name 'fix_markdown_file' combined with server context (Windows Operations MCP with file operations capabilities) indicates the tool modifies markdown files. The name implies irreversible or semi-reversible text transformation rather than deletion.
