Agent Skill
Skill Creator
Builds, tests, and refines Agent Skills through an evaluation loop rather than treating SKILL.md as static prose.
What is Skill Creator?
Skill Creator provides a disciplined workflow for authoring new skills and improving existing ones. It separates the skill's triggering description from its operating instructions, creates representative test prompts, runs qualitative and quantitative evaluations, and revises the package when real agent behavior exposes ambiguity. The result is a skill that is easier to discover and more dependable after activation.
Key capabilities
Structured authoring
Defines scope, trigger conditions, instructions, examples, and bundled resources as separate concerns.
Evaluation prompts
Uses realistic positive and negative prompts to test whether the skill triggers at the right moments.
Behavioral refinement
Revises instructions using observed failures instead of polishing wording without evidence.
Benchmark support
Supports comparison runs so improvements can be checked against a baseline.

Package a repeatable engineering or content process for consistent agent use.
Repair weak triggering
Improve a skill that is ignored, over-triggered, or selected for the wrong requests.
