What the reviewer found
Skill that fine-tunes a model via Fireworks-managed GPUs using user-provided dataset and a fixed schema-validation reward function; legitimate ML workflow, no exfiltration or destructive actions.

How this review was made
Sonnet 5 read the files above on 6 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
