Core Features & Use Cases

  • Read/Write: Read and write files within the active workspace.
  • Patch Application: Apply patches to files while respecting workspace boundaries.
  • Globbing: Find files with glob patterns to support bulk updates or checks.

Quick Start

Use the filesystem skill to read a config file, modify a setting, and apply a patch to the target file within the project.

FAQPage Schema
How do I read and write files within my project workspace?

This Skill provides read and write access to files in your active project. Use fs.readFile to retrieve file contents and fs.writeFile to save changes, with all operations confined to your workspace boundaries for safety.

Can I apply patches to files in my project?

Yes, the Skill includes fs.applyPatch to apply patches to files while respecting workspace scope. This lets you make targeted updates to existing files without manual editing.

How do I find multiple files using glob patterns?

Use fs.glob to search for files matching patterns within your workspace. This supports bulk operations like reading, updating, or validating multiple files based on path matching.

What safeguards prevent filesystem operations from going outside my project?

The Skill enforces workspace-scoped access, restricting all read, write, and patch operations to your active project directory. This containment prevents accidental or unintended changes outside the intended scope.

Can I use this Skill to modify configuration files?

Yes, filesystem operations support reading config files, modifying settings, and writing updates back. Combined with glob patterns, you can bulk-update configuration across multiple files in your project.
