Skill Creator
A skill for creating new skills and iteratively improving them.
At a high level, the process of creating a skill goes like this:
- Decide what you want the skill to do and roughly how it should do it
- Write a draft of the skill
- Create a few test prompts and run claude-with-access-to-the-skill on them
- Help the user evaluate the results both qualitatively and quantitatively
- Rewrite the skill based on feedback from the user's evaluation of the results
- Repeat until you're satisfied
- Expand the test set and try again at larger scale
Creating a skill
Start by understanding the user's intent. The current conversation might already
contain a workflow the user wants to capture. If so, extract answers from the
conversation history first — the tools used, the sequence of steps, corrections
the user made, input/output formats observed. The user may need to fill gaps.
Write SKILL.md with YAML frontmatter containing a concise name and a precise
description that explains what the skill does and when it should be used. Keep
the body focused on workflow, edge cases, examples, and references.
