Skill Creator
Author, package, and iterate Agent Skills (SKILL.md) with eval loops so your custom capabilities install cleanly across Claude Code, Cursor, and Codex.
Overview
Skill Creator is a journey-wide agent skill that helps you author, evaluate, and package SKILL.md capabilities—usable whenever a solo builder needs a repeatable agent procedure before shipping more prompts.
Install
npx skills add https://github.com/aiskillstore/marketplace --skill skill-creatorWhat is this skill?
- Guides authoring structured SKILL.md with frontmatter agents can parse reliably
- Supports packaging skills for marketplace or private repos with license metadata (e.g. Apache-2.0)
- Emphasizes eval-style iteration: parallel runs, token use, and pass-rate feedback on skill changes
- Meta workflow for shrinking oversized instructions into agent-compatible single-line descriptions
- Bridges solo builder workflows from draft skill → test → publish in agent marketplaces
Adoption & trust: 586 installs on skills.sh; 349 GitHub stars; 3/3 security scanners passed (skills.sh audits).
What problem does it solve?
You keep re-pasting the same instructions into chat because you never packaged them as a testable, installable agent skill.
Who is it for?
Builders maintaining multiple agent skills who want eval-driven refinement and marketplace-ready metadata.
Skip if: One-shot tasks with no reuse, or teams that only need MCP servers without procedural SKILL.md assets.
When should I use this skill?
You are creating, refactoring, or publishing an agent skill and need eval-driven SKILL.md structure.
What do I get? / Deliverables
You ship a versioned skill with clear invoke triggers and eval feedback, ready to list in a marketplace or drop into `.cursor` / Claude skill paths.
- SKILL.md skill package
- Eval notes or pass-rate comparison across variants
