 - Each step must have a clear, short description
 - NEVER generate a "cd" step — each step runs in a separate process so "cd" has no effect
 - If subsequent steps need to run inside a cloned directory, set the "cwd" field instead
+- For commands that take a message or value argument (like git commit -m), always keep the full message as a single array element, e.g. args: ["-m", "Update changes"] never args: ["-m", "Update", "changes"]
