Describes the domain (filenames/paths) and a couple of actions (strip directory, strip suffix), but doesn't list multiple concrete actions beyond those two. It's more specific than vague but not comprehensively detailed.

Clearly answers both 'what' (strip directory and suffix from filenames) and 'when' (Use when extracting just the filename from a path, or removing file extensions), with an explicit 'Use when...' clause.

Includes natural terms users would say: 'filename', 'path', 'file extensions', 'directory', 'suffix'. These cover the common ways users would describe this need.

Very specific niche — stripping directory paths and suffixes from filenames is a narrow, well-defined task unlikely to conflict with other skills.

The content is lean and efficient. It documents flags in a compact table, provides examples without unnecessary explanation, and the Gotchas section contains genuinely non-obvious information (like the parameter expansion alternative and trailing slash behavior). No concepts are over-explained.

Every example is a concrete, copy-paste ready bash command with expected output clearly shown. Common patterns like script name extraction and shell variable assignment are included, making this immediately usable.

This is a simple, single-purpose utility skill with no multi-step process. The single action (stripping directory/suffix) is unambiguous, and the examples clearly demonstrate each flag variation. No destructive or batch operations require validation checkpoints.

For a simple single-purpose skill under 50 lines of substantive content with no need for external references, the content is well-organized into logical sections (Synopsis, Flags, Examples, Gotchas) that are easy to scan and navigate.
