About
skill-evolver is a Claude Code marketplace for an autonomous skill evolution engine. It iteratively improves existing skills through A/B testing, mechanical grading, and small atomic edits so you do not hand-tune prompts manually. Reach for it when a skill works but needs measurable, automated refinement across evaluation runs.
- Autonomous outer-loop skill optimization
- A/B testing with mechanical grading
- Atomic skill prompt changes
- /skill-evolver command after marketplace install

How do I systematically improve a Claude Code skill's prompt quality instead of guessing one edit at a time?
Autonomously evolve Claude Code skills via A/B tests, mechanical grading, and atomic prompt changes with /skill-evolver.
Who is it for?
Developers maintaining custom skills who want automated grading and iterative prompt optimization inside Claude Code.
Skip if: Teams with no custom skills or those satisfied with one-shot manual SKILL.md edits.
What you get
The engine produces revised skill definitions with evidence from A/B runs and mechanical scores rather than unmeasured prompt tweaks.

FAQ
How do I run evolution?
Add the marketplace, install Skill Evolver, then invoke /Skill Evolver with the target skill name.
What makes changes safe?
The engine applies atomic prompt changes and uses mechanical grading across A/B comparisons before accepting improvements.
Can it evolve itself?
Yes—the README documents self-iteration by evolving the Skill Evolver skill from a local clone.
