file-modify-skill

What problem does it solve?

This Skill removes the need to manually open, copy, and edit files by letting an AI create new files or make precise surgical changes through controlled string replacement.

Core Features & Use Cases

• Write new files: Create or wholesale-replace a file’s contents by providing the full content.
• Edit existing files: Perform safe, targeted find-and-replace using old_string and new_string (optionally replacing all matches).
• Deterministic responses: Returns a structured operation result suitable for a filesystem backend workflow.

Use case: Update a configuration or source file by changing a single line or small block, without rewriting the entire file or risking unrelated modifications.

Quick Start

Use the file-modify-skill to edit the file /path/to/file.py by replacing the unique text old_string with new_string.
