Community Extensions

Note

Community extensions are independently created and maintained by their respective authors. Maintainers only verify that catalog entries are complete and correctly formatted — they do not review, audit, endorse, or support the extension code itself. The Community Extensions website is also a third-party resource. Review extension source code before installation and use at your own discretion.

🔍 Browse and search community extensions on the Community Extensions website.

The following community-contributed extensions are available in catalog.community.json:

Categories (common values, but any string is allowed):

  • docs — reads, validates, or generates spec artifacts
  • code — reviews, validates, or modifies source code
  • process — orchestrates workflow across phases
  • integration — syncs with external platforms
  • visibility — reports on project health or progress

Effect (canonical extension.yml/catalog values):

  • read-only — produces reports without modifying files (displayed as Read-only in the table)
  • read-write — modifies files, creates artifacts, or updates specs (displayed as Read+Write in the table)
Tip

Extension authors can declare category and effect in their extension.yml under the extension: block. These fields are also available in catalog.community.json for tooling and the CLI (specify extension info).
