+  description: |
+    nl2sh-1.5b is a 1.5B Qwen2.5-Coder fine-tune that converts plain-English
+    requests into single POSIX or Bash commands. This Q4_K_M GGUF is 941 MB
+    and is designed for fast CPU inference.
+
+    Use the system prompt from the model card and review every generated
+    command before execution. The model can produce destructive commands and
+    cannot inspect the local filesystem.
