Agent Skills: Mastra Documentation Guidelines

Mastra Documentation Guidelines

Instructions and styleguides for writing and maintaining Mastra documentation. This skill should be used whenever creating or updating documentation for Mastra to ensure consistency, clarity, and quality across all docs.

Path convention

@docs/ references in this skill map to the docs/ directory in the workspace root. For example, @docs/styleguides/STYLEGUIDE.md resolves to docs/styleguides/STYLEGUIDE.md. Always use the view tool with the workspace path, do not use skill_read for these files.

Scope

• @docs/ - This folder contains the source code and contents of the documentation site. All documentation for Mastra should be created and maintained here.
• @docs/src/content/en/ - This subfolder contains the actual markdown files for the documentation site, organized into docs/, guides/, and reference/ sections. The models/ subfolder contains auto-generated documentation for model providers and should not be edited manually.

Styleguides

Follow the general styleguide at @docs/styleguides/STYLEGUIDE.md for all documentation. Additionally, refer to these specific styleguides when writing different types of documentation:

• @docs/styleguides/DOC.md - For any file inside @docs/src/content/en/docs/
• For any file inside @docs/src/content/en/guides/ choose the correct styleguide based on content:
  • @docs/styleguides/GUIDE_QUICKSTART.md - For quickstart guides that get the reader to a working result as fast as possible with a specific library/framework.
  • @docs/styleguides/GUIDE_TUTORIAL.md - For tutorial guides that teach the reader how to build something specific with Mastra, going deeper into concepts.
  • @docs/styleguides/GUIDE_INTEGRATION.md - For integration guides that provide a comprehensive reference for using Mastra with a specific external library or ecosystem.
  • @docs/styleguides/GUIDE_DEPLOYMENT.md - For deployment guides that walk the reader through deploying their Mastra application to a specific platform.
• @docs/styleguides/REFERENCE.md - For any file inside @docs/src/content/en/reference/

Linting

The documentation uses three tools to maintain quality and consistency:

• prettier: For consistent formatting. It also formats the code blocks in the markdown files itself. The base layer of linting.
• remark: Lints markdown files for specific markdown issues, e.g. heading levels, list styles, consistent usage of bold, italics, etc. The middle layer of linting.
• vale: Lints prose for grammar, style, and consistency issues. The top layer of linting.

Inside @docs/, you can run the following commands to lint the documentation:

• prettier: npm run format - Automatically formats all files using prettier.
• remark: npm run lint:remark - Lints all markdown files using remark and reports any issues.
• vale: npm run lint:vale:ai - Lints all markdown files using vale with a minimum alert level of "error" and outputs results in a line format.
