Skill Creator
Author, structure, and iterate agent skills with consistent SKILL.md patterns and evaluation-minded workflows.
Overview
Skill Creator is a journey-wide agent skill that helps you author and refine SKILL.md-based capabilities—usable whenever a solo builder needs to turn repeated agent workflows into reusable, catalog-ready skills.
Install
npx skills add https://github.com/composiohq/skills --skill skill-creatorWhat is this skill?
- Meta skill for defining reusable agent capabilities in SKILL.md format
- Supports structuring triggers, scope, and procedural steps agents can follow reliably
- Oriented toward Composio-style skill libraries and composable agent workflows
- Helps solo builders turn repeat prompts into installable, shareable skills
- Pairs with catalog and eval habits so skills are measurable, not one-off chat hacks
Adoption & trust: 1.7k installs on skills.sh; 87 GitHub stars; 3/3 security scanners passed (skills.sh audits).
What problem does it solve?
You keep re-explaining the same agent procedures in chat instead of shipping a documented, triggerable skill your future self and teammates can install.
Who is it for?
Indie builders maintaining a personal or team skill repo who want consistent format, triggers, and handoffs between skills.
Skip if: One-shot questions with no repeat workflow, or teams that only consume third-party skills and never author their own.
When should I use this skill?
You are creating, editing, or standardizing agent skills in SKILL.md format, especially for Composio-style libraries or before publishing to a skill catalog.
What do I get? / Deliverables
You produce a structured SKILL.md skill with clear invoke rules and deliverables that fits agent repos and directories like Prism or skills.sh.
- SKILL.md with name, description, triggers, and procedural body
- Optional eval or checklist notes for skill quality before share/install
Recommended Skills
Journey fit
Useful at every journey phase - explore requirements and options before committing to a direction.
Where it fits
Capture a scoping checklist as a skill before greenlighting an MVP build.
Author a new integration skill with frontmatter triggers and test it in your agent repo.
Turn your code-review ritual into a skill with explicit deliverables and severity buckets.
Refactor a hotfix runbook into a skill after an outage so the agent follows the same steps next time.
How it compares
Skill packaging and authoring guidance—not an MCP server runtime or a hosted integration marketplace by itself.
Common Questions / FAQ
Who is skill-creator for?
Solo and indie developers who ship with agentic IDEs and want to create, document, and maintain their own SKILL.md skills in a repo such as composiohq/skills.
When should I use skill-creator?
In Build when adding agent-tooling; in Validate when prototyping agent-assisted product workflows; in Operate when codifying incident or deploy runbooks; anytime you formalize a repeated agent ritual into a skill.
Is skill-creator safe to install?
Review the Security Audits panel on this Prism page; authoring skills may touch your filesystem and git repo but should not require broad secrets unless your template integrations do.
