tashfeenahmed Write File Skill
Write content to a file, creating it if it doesn't exist.
When to Use
Use the write_file skill for:
- Creating new files: New source files, configs, documentation
- Overwriting files: Replace entire file contents
- Appending to files: Add content to end of existing file
- Creating with directories: Auto-create parent directories

"path": "src/new-file.ts",
"content": "export const hello = 'world';",
"createDirs": true
}

"content": "New log entry\n",
"append": true

Limitations
- Text only — this tool writes UTF-8 text. It cannot produce binary files (PDF, images, DOCX, ZIP, etc.). Writing text to a
.pdfor other binary extension will create a corrupt, unreadable file. - To generate PDFs, use the pdf skill (write a .typ file, compile with typst).
- To generate images, use bash with an appropriate library.
Security
- Paths are validated to stay within workspace
- Cannot write to system directories
- Symlinks escaping workspace are blocked
