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 artifactscode— reviews, validates, or modifies source codeprocess— orchestrates workflow across phasesintegration— syncs with external platformsvisibility— reports on project health or progress
Effect (canonical extension.yml/catalog values):
read-only— produces reports without modifying files (displayed asRead-onlyin the table)read-write— modifies files, creates artifacts, or updates specs (displayed asRead+Writein 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).
