# 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](https://speckit-community.github.io/extensions/).**

The following community-contributed extensions are available in [`catalog.community.json`](https://github.com/github/spec-kit/blob/main/extensions/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`).
