Overview
What you provide
- A specification or code change, project constraints and the selected skill.
What you get
- Structured plans, implementation steps, reviews and verification records.
Choosing this tool
Use this collection when a team wants named commands and reusable engineering criteria rather than one large project prompt. Existing projects can adopt verification and review first. Superpowers provides a cohesive staged workflow; Ponytail concentrates on implementation restraint and simplification.
A decision worked through
A team can begin with code review on an existing pull request before enabling build and ship workflows. Check the supplementary references are installed: upstream documents that installing an individual skill omits repository-level shared checklists.

| SuperpowersRead profileOfficial source ↗ | MIT; host usage extra | Full source | Request → staged implementation | Requires a compatible agent |
| PonytailRead profileOfficial source ↗ | MIT; agent billed separately | Repository skill | Code change → smaller reviewed solution | Host adapters have different commands |
Setup & workflow
- List the available skills before choosing a scope.
- Install the collection or supply missing references for individual skills.
- Run review or test on an existing change before adopting the full lifecycle.
Requirements & installation
- A skill-capable assistant and access to the repository references needed by the selected workflow.
npx skills add addyosmani/agent-skills --listLimits & review
- Workflow commands can overlap built-in assistant commands; namespaced invocation may be required. Individual-skill installation has a documented shared-reference gap.
Your part
- Choose the workflows to enable and inspect evidence before accepting a release.
