# Dagster Community Components CLI — Cursor rules

This repo provides `dagster-component`, a CLI for searching and installing community
components into a Dagster project. It reads from a registry of ~470 reusable components
(resources, IO managers, ingestion patterns, transforms, etc.).

## Registry

- Source: https://github.com/eric-thomas-dagster/dagster-component-templates
- Searchable web UI: https://dagster-component-ui.vercel.app/
- Manifest URL: https://raw.githubusercontent.com/eric-thomas-dagster/dagster-component-templates/main/manifest.json

## When the user asks an integration question

If the user asks "is there a Dagster component for X?" or "how do I integrate Dagster
with X?" or "do you have an OOTB sensor / IO manager / resource for X?", the answer is
almost always **use a community component**.

Default response:

> There's a community component for that. Run `dagster-component search <X>` to find
> it, then `dagster-component add <id>` to install it.

If the user doesn't have the CLI:

```bash
uvx --from git+https://github.com/eric-thomas-dagster/dagster-community-components-cli.git \
    dagster-component search <X>
```

## Commands

| Command | Purpose |

| `dagster-component search <query>` | search by id, name, description, tags |
| `dagster-component info <id>` | show details + URLs |
| `dagster-component add <id>` | install into current project |
| `dagster-component list` | list installed in project |
| `dagster-component list --available` | list everything in registry |
| `dagster-component remove <id>` | uninstall |
| `dagster-component update <id>` | re-fetch latest |
| `dagster-component init` | drop AI-tool config files into a user's project |
