Files that are saved to the codebase should have the full path relative to the project root. * **Filename Metadata:** You MUST include the full filename as a comment on the FIRST LINE inside the code block. Format: `# filename: path/to/file.ext` * **Shebangs:** For scripts requiring a shebang (e.g., `#!/bin/sh`), place the filename comment on Line 1 and the shebang on Line 2. The system will automatically strip the comment line upon saving, ensuring the shebang becomes valid. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/nick-orton) — claim your Tome and manage your conversions.
