npx skills add https://mastra.ai/

Included skills

mastra

Single comprehensive skill for all Mastra development. Uses progressive disclosure with reference files covering:

• Setup & Installation (references/create-mastra.md): CLI and manual project setup
• Embedded Docs Lookup (references/embedded-docs.md): Find APIs in node_modules/@mastra/*/dist/docs/
• Remote Docs Lookup (references/remote-docs.md): Fetch from https://mastra.ai/llms.txt
• Troubleshooting (references/common-errors.md): Common errors and solutions
• Migrations (references/migration-guide.md): Version upgrade workflows
• Mastra API CLI (references/mastra-api.md): Inspect and call resources on local, platform, or remote servers
• Advanced Trace Queries (references/trace-query.md): Select completed traces with recursive predicates and cursor pagination
• Feedback (references/feedback.md): report verified bugs and concrete documentation defects to the Mastra team

Main skill file teaches core concepts and routes to appropriate reference files based on user questions.

mastra-factory

Standalone Factory supervisor skill for coding agents using mastra api factory. Covers first-use CLI/login checks and URL-based connection from any directory, project and queue summaries, work-item session/thread and memory inspection, health interpretation, and user-authorized operations.

• Connection and installation: connect to your own deployment without a repository or project link file; choose the correct agent and installation scope.
• Session and memory inspection: find your work, inspect progress and OM evidence, and distinguish findings from repair authorization.
• Supervisor commands: contracts, output control, and safe mutations.

Install just the Factory skill with interactive agent/scope selection:

npx skills add mastra-ai/skills --skill mastra-factory

For a global install, specify your supported agent explicitly (--agent <agent> -g). PromptScript does not support global installation; use project scope for that agent instead, and confirm the skill is linked (a copied-but-"not linked" result means it is not active yet). Multi-agent installs can partially succeed: verify the intended agent with npx skills list (add -g for global scope) and confirm its skill references are present.

Manual installation

git clone https://github.com/mastra-ai/skills.git

Then configure your agent to load skills from the cloned directory.

.well-known skills discovery

This repository is served via the RFC 8615 Well-Known URI at https://mastra.ai/.well-known/skills/.

Agents can discover available skills by fetching:

• Index: https://mastra.ai/.well-known/skills/index.json
• Mastra skill: https://mastra.ai/.well-known/skills/mastra/SKILL.md
• Factory skill: https://mastra.ai/.well-known/skills/mastra-factory/SKILL.md

This enables automatic skill discovery without manual configuration.
