notebook-path-policy

What problem does it solve?

This Skill prevents broken or unsafe file output behavior by standardizing how Mathematica chooses an output directory when users provide only a filename or a relative path.

Core Features & Use Cases

• NotebookDirectory-first resolution: Selects NotebookDirectory[InputNotebook[]] when it exists and is a valid directory, otherwise falls back to $packageDirectory.
• Bare filename and relative path handling: Treats “bare filename” output requests as intended to be placed in the resolved output directory.
• Explicit absolute path priority: Uses an explicitly provided absolute path as the highest-priority destination to respect user intent.
• Use Case: When generating result files during a Claude-assisted coding session, ensure outputs consistently land in the notebook’s folder (or the package folder) instead of unpredictable locations.

Quick Start

Use notebook-path-policy to decide whether the output file should be written to NotebookDirectory[InputNotebook[]] or $packageDirectory when the user specifies only a bare filename.
