DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Prompt capture

Write tool description

27 model strings share this prompt, byte for byte.

This renders the markdown inside the description, so it isn't quite the description itself. The raw view and the plain text are the bytes as they were sent.

Writes a file to the local filesystem.

Usage:

  • This tool will overwrite the existing file if there is one at the provided path.
  • 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.
  • ALWAYS prefer editing existing files in the codebase. NEVER write new files unless explicitly required.
  • NEVER proactively create documentation files (*.md) or README files. Only create documentation files if explicitly requested by the User.
  • Only use emojis if the user explicitly requests it. Avoid writing emojis to files unless asked.
