General Skill Creator

A skill for creating portable Agent Skills and improving them through realistic test runs.

Agent Skills are reusable instruction packages for coding agents. A portable skill should rely on the shared skill pattern: a SKILL.md file with frontmatter, concise instructions, and optional bundled resources such as scripts/, references/, assets/, and evals/.

Core Loop

Work through this loop:

1. Understand the user intent and the target agent environments.
2. Confirm where the skill should be installed or authored.
3. Draft or edit the skill.
4. Create realistic test prompts.
5. Run the prompts with the skill and against a baseline.
6. Help the user review qualitative outputs and quantitative checks.
7. Improve the skill from the feedback.
8. Repeat until the skill is useful, portable, and lean.
