A walkthrough of the anatomy of a skill, using a document-generation skill from a public repository as the example: a markdown file whose short description is what the model reads first to decide whether the skill applies, instructions in the body, and referenced scripts in the same folder. The argument is that the scripts are the point, because they give deterministic control.
Help me write a skill properly rather than as a long prompt in a folder. First, for the task I describe below, split it into the parts that must produce identical output every time and the parts that genuinely need judgment. Write the deterministic parts as a script the skill calls, and keep only the judgment parts as instructions in the skill body. Then write the short description at the top as carefully as the rest, since that is what decides whether the skill ever gets used, and tell me what requests it would and would not match. Finally, show me how to test that the skill triggers when it should and that the script produces the same result on repeated runs.
