Usage:
4
- This tool will overwrite the existing file if there is one at the provided path.
5
- If this is an existing file, you MUST use the Read tool first to read the file's contents. This tool will fail if you did not read the file first.
6
- Prefer the Edit tool for modifying existing files — it only sends the diff. Only use this tool to create new files or for complete rewrites.
7
- NEVER create documentation files (*.md) or README files unless explicitly requested by the User.
8
- Only use emojis if the user explicitly requests it. Avoid writing emojis to files unless asked.
3
When to use: creating a new file, or fully replacing one you've already Read. Overwriting an existing file you haven't Read will fail. For partial changes, use Edit instead.
