- Claude.ai-specific instructions
- Cowork-Specific Instructions
Limitations to know about
- The file has separate sections for Claude.ai and Cowork. There is no section for Duet, so the source does not tell you how the evaluation loop behaves there.
- Evaluation results describe your test cases, not every situation the skill will meet. Keep the cases and rerun them after each change.
Also: A well-written skill is not automatically safe or effective. Evaluate it in the actual environment before trusting it.
When it is not the right fit
- The task happens once, so a plain prompt is cheaper than a reusable skill.
- You cannot say what a correct result looks like, so there is nothing to evaluate.
A small task to start with
This is our suggested evaluation prompt, not a tested result or an installation command.
Help me design a skill for monthly reporting. First define required inputs, output format and three evaluation cases.
Use non-sensitive sample data first. Compare the answer with the original inputs and record what needed correction before expanding the workflow.
Before you rely on it
- Write the success criteria down before drafting the skill.
- Keep three realistic test cases that include one awkward input.
- Save the previous version so you can compare results after an edit.
Where to get started
- Read the upstream skill source, dependencies and license.
- In Claude, check Customize for the relevant skill or plugin. Follow the current official installation guide rather than guessing a Duet command.
- Verify availability in your own environment and run a small, reversible task.
