-description: Review a tiny CLI against the 10 AXI principles and produce a report card.
----
-## Prompt
-There is a small command-line tool named `greet` in the current directory (`./greet`).
-Review it against the 10 AXI (Agent eXperience Interface) principles by running it black-box, and give me a report card that scores each principle with a concrete verdict and a fix for anything that isn't a clean pass.
-
-## Hard assertions
-```sh
-grep -qiE 'AXI|principle' "$OUTPUT"
-grep -qiE 'PASS|PARTIAL|FAIL' "$OUTPUT"
-```
-
-## Soft criteria
-- The review scores each of the 10 AXI principles with an explicit verdict grounded in the tool's actual observed output, not in guesses about its source.
-- Every principle that is not a clean pass carries a concrete, actionable fix.
-- The review is driven by running the `greet` tool and citing what it emitted, rather than by generic CLI advice.
