•

Executes fundamental file system operations including reading, writing, patching, and pattern-based searching within a project workspace.

Acts as an essential execution-layer interface for managing project files, allowing Claude to interact directly with the local environment. It facilitates core file operations such as reading file contents, writing new data, applying precise patches to existing codebases, and locating files using glob patterns. Built with safety in mind, it restricts all operations to the active project workspace, providing a secure and reliable way to automate code modifications and file management tasks during development.

Key Features

01Read and write file content directly in the workspace

Commands

  • fs.readFile
  • fs.writeFile
  • fs.applyPatch
  • fs.glob

Constraints

  • Never access paths outside the active project workspace unless explicitly granted.
  • Do not embed governance or routing logic in this skill; it only exposes filesystem capabilities.
