Example: File Inspector

Another dummy/example skill — no personal information, no secrets, no private infrastructure. Demonstrates a skill that actually does a small task using ordinary shell tools, rather than just being static prose.

Procedure

Given a file path from the user:

1. Confirm the file exists (test -f "$PATH"); if not, say so and stop.
2. Report:

• Line count: wc -l "$PATH"
• Byte size: wc -c "$PATH"
• Extension (if any): everything after the last . in the filename
• File type guess: file "$PATH" if available, otherwise infer from

extension

1. Present the four facts as a short list. Do not speculate about file

contents beyond what these commands report.

Why this is a good "second skill" to read

It shows the two things every real skill needs beyond example-hello-world: a numbered procedure the agent can follow mechanically, and an explicit boundary ("do not speculate beyond what these commands report") that keeps the skill's output trustworthy.
