Skill Creator
Author, structure, and iterate agent skills (SKILL.md packages) with evaluation-minded workflows so capabilities are repeatable across Claude Code and similar agents.
Overview
skill-creator is an agent skill most often used in Build (also Ship review, Grow content ops) that helps you design, document, and refine installable agent skills with evaluation-friendly structure.
Install
npx skills add https://github.com/anthropics/financial-services-plugins --skill skill-creatorWhat is this skill?
- Meta skill for packaging procedural knowledge as installable agent capabilities
- Aligns with SKILL.md conventions: name, description, triggers, and scoped instructions
- Supports eval-oriented iteration: compare runs, tighten triggers, and reduce token waste
- Fits financial-services plugin bundles where domain skills need consistent structure
- Apache 2.0 licensed artifact suitable for fork-and-customize in your own skill repo
Adoption & trust: 636 installs on skills.sh; 30.5k GitHub stars; 2/3 security scanners passed (skills.sh audits).
What problem does it solve?
You have useful agent know-how scattered in chat logs but no versioned SKILL.md package with clear triggers and measurable behavior.
Who is it for?
Solo builders creating or maintaining a library of domain skills (including finance plugins) who want reusable agent capabilities.
Skip if: Builders who only need a single throwaway prompt with no triggers, packaging, or intent to publish or reuse the capability.
When should I use this skill?
Use when starting or refactoring an agent skill package that must be installed, triggered reliably, and improved through structured iteration.
What do I get? / Deliverables
You produce a structured skill definition ready to install, test in parallel runs, and improve before it becomes a default workflow step.
- SKILL.md-oriented skill specification
- Defined triggers and scoped instructions
- Iteration notes or eval checklist for subsequent runs
Recommended Skills
Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Build / agent-tooling because the primary artifact is a skill package others install—not a shipped customer feature. Agent-tooling is where procedural knowledge, triggers, and deliverables are defined before you rely on the skill in Ship or Grow workflows.
Where it fits
Draft a new compliance-check skill with explicit invoke triggers before adding it to your finance plugin.
Tighten skill instructions after a review pass finds ambiguous deliverables or missing guardrails.
Turn recurring customer-support steps into a installable support skill for your agent stack.
How it compares
A meta authoring pattern for SKILL.md skills—not an MCP server integration or a one-shot code generator.
Common Questions / FAQ
Who is skill-creator for?
Indie developers and small teams building agent skill libraries—especially alongside Anthropic-style plugin repos—who need consistent skill shape and iteration discipline.
When should I use skill-creator?
In Build when drafting a new skill; in Ship when tightening triggers after code review; in Grow when documenting support or ops playbooks as agent skills—any time a capability should survive beyond one chat thread.
Is skill-creator safe to install?
Check the Security Audits panel on this Prism page; skills you author can later request shell, network, or secrets—scope permissions explicitly in each skill you create.
