+description: >-
+  Use when navigating, testing, or verifying a RHDH instance via
+  playwright-cli. Covers guest login, sidebar navigation, catalog browsing,
+  entity page inspection, tab verification, and plugin exploration. Trigger on
+  "check RHDH", "verify catalog entity", "entity should have tab",
+  "navigate RHDH", or any RHDH UI testing task.
+---
+
+# Play RHDH
+
+Automate RHDH UI navigation and verification using `playwright-cli` (NOT the Playwright MCP).
+
+## Quick Start
+
+```bash
+# Always use --browser chromium
+playwright-cli open <RHDH_URL> --browser chromium
+```
+
+The URL is never hardcoded — the user provides it (or it comes from context like CLAUDE.md).
+
+## Authentication — Guest Login
+
+After opening a RHDH instance, check whether a login page appeared. If the page title contains "Sign In" or "Log in", or the snapshot shows sign-in buttons, log in as guest:
+
+```bash
+# Take a snapshot to check for login
+playwright-cli snapshot
+
+# If a login page is detected, look for a guest sign-in option:
+#   - Button or link matching: "Enter" (on guest sign-in provider card)
+#   - Or a "Guest" / "Sign in as Guest" button
+# Click it:
+playwright-cli click "<ref>"      # ref of the guest sign-in button
+```
+
+RHDH login pages typically show provider cards. The guest provider shows a title like "Guest" with an "Enter" button. Click the "Enter" button on the guest card.
+
+After login, verify navigation succeeded by checking that the sidebar appeared:
+
+```bash
+playwright-cli snapshot --depth 3
+# Confirm: navigation "sidebar nav" is present
+```
+
+## Sidebar Navigation
+
+The sidebar uses `navigation "sidebar nav"` containing links. Navigate by clicking the link with the target label.
+
+| Destination | Selector pattern |
+|---|---|
+| Home | `link "Home"` |
+| Catalog | `link "Catalog"` |
+| APIs | `link "APIs"` |
+| Docs | `link "Docs"` |
+| Create | `link "Create"` |
+| Explore | `link "Explore"` |
+| Settings | `link "Settings"` |
+| Notifications | `link "Notifications"` |
+| Search | `button "Search"` |
+
+Additional sidebar items (plugins) appear below a separator. Their labels match their menu name (e.g., `link "Tech Radar"`).
+
+```bash
+# Navigate to a sidebar item
+playwright-cli click "getByRole('navigation', { name: 'sidebar nav' }).getByRole('link', { name: 'Catalog' })"
+```
+
+## Catalog Page
+
+After navigating to the catalog, the page shows filters and a table of entities.
+
+### Filters
+
+| Filter | Element type | Locator |
+|---|---|---|
+| Kind | button (shows current value) | `button "Component"` (or current kind) |
+| Type | button | `button "all"` (or current type) |
+| Owner | combobox + textbox | `textbox "Owner"` |
+| Lifecycle | combobox + textbox | `textbox "Lifecycle"` |
+| Tags | combobox + textbox | `textbox "Tags"` |
+
+To filter by Kind, click the Kind button and select from the dropdown:
+
+```bash
+playwright-cli click "getByRole('button', { name: 'Component' })"
+playwright-cli snapshot   # find the desired kind option
+playwright-cli click "<ref>"  # click the desired kind
+```
+
+### Search the Catalog
+
+```bash
+playwright-cli fill "getByRole('textbox', { name: 'Search' })" "my-entity"
+```
+
+### Catalog Table
+
+The entity table has columns: Name, System, Owner, Type, Lifecycle, Description, Tags, Actions.
+
+Entity names in the table are links. Their URL pattern is: `/catalog/{namespace}/{kind}/{name}`
+
+```bash
+# Click an entity by name
+playwright-cli click "getByRole('link', { name: 'artist-lookup' })"
+```
+
+### Personal vs All
+
+The catalog has a menu toggle between "Personal" (Owned / Starred) and "RHDH" (All):
+
+```bash
+# Switch to "All" entities
+playwright-cli click "getByRole('menuitem', { name: /All/ })"
+```
+
+## Entity Page
+
+An entity page has:
+1. **Header** — shows kind, type, entity name, and metadata (Owner, Lifecycle)
+2. **Tabs** — `tablist "Tabs"` containing `tab` elements
+3. **Content area** — `article` below the tabs
+
+### Verify an Entity Exists
+
+```bash
+playwright-cli open "<RHDH_URL>/catalog/default/component/<entity-name>" --browser chromium
+playwright-cli snapshot --depth 3
+# Confirm: heading with entity name is present
+# The page title format: "<entity-name> | <tab> | <site-title>"
+```
+
+Or search through the catalog:
+
+```bash
+playwright-cli open "<RHDH_URL>/catalog" --browser chromium
+playwright-cli fill "getByRole('textbox', { name: 'Search' })" "<entity-name>"
+# Check the table for a matching row
+playwright-cli snapshot
+```
+
+### Read Entity Metadata
+
+From the entity page snapshot, find:
+- **Kind + Type**: `paragraph` above the heading (e.g., "component — service")
+- **Owner**: under a "Owner" label, a link to the owning group
+- **Lifecycle**: under a "Lifecycle" label (e.g., "experimental", "production")
+- **System**: in the About card under "System" heading
+
+### Verify a Tab Exists
+
+```bash
+playwright-cli snapshot
+# Look for: tablist "Tabs" containing tab elements
+# Example output:
+#   tablist "Tabs":
+#     tab "Overview" [selected]
+#     tab "Docs"
+#     tab "APIs"
+#     tab "Todo"
+```
+
+Check that the expected tab name appears in the tablist. Tabs are `tab` role elements inside `tablist "Tabs"`.
+
+```bash
+# Click a specific tab
+playwright-cli click "getByRole('tab', { name: 'Docs' })"
+```
+
+### About Card
+
+The entity Overview tab contains an "About" card (`heading "About"`) with:
+- Description, Owner, System, Tags, Kind, Type, Lifecycle
+- Links: "View Source", "View TechDocs"
+
+## Common Verification Patterns
+
+### Check that a catalog entity exists
+
+```bash
+playwright-cli open "<URL>" --browser chromium
+# Handle login if needed (see Authentication section)
+playwright-cli goto "<URL>/catalog/default/component/<name>"
+playwright-cli snapshot --depth 4
+# SUCCESS: heading with entity name is visible
+# FAILURE: page shows "Entity not found" or similar error
+```
+
+### Entity should have a specific tab
+
+```bash
+playwright-cli goto "<URL>/catalog/default/component/<name>"
+playwright-cli snapshot --depth 4
+# Find: tablist "Tabs" → check for tab "<expected-tab>"
+```
+
+### Navigate sidebar and verify page loaded
+
+```bash
+playwright-cli click "getByRole('navigation', { name: 'sidebar nav' }).getByRole('link', { name: '<Page>' })"
+playwright-cli snapshot --depth 3
+# Confirm heading or page content matches expected page
+```
+
+### Screenshot for evidence
+
+```bash
+playwright-cli screenshot --filename rhdh-evidence.png
+# Saved to .playwright-cli/rhdh-evidence.png
+```
+
+## URL Patterns
+
+| Resource | URL pattern |
+|---|---|
+| Catalog list | `/catalog` |
+| Entity by kind | `/catalog/{namespace}/{kind}/{name}` |
+| API docs | `/api-docs` |
+| TechDocs | `/docs` |
+| Create (templates) | `/create` |
+| Settings | `/settings` |
+
+Default namespace is `default`. Common kinds: `component`, `system`, `group`, `user`, `api`, `resource`, `template`, `domain`, `location`.
+
+## Important
+
+- **Always** use `playwright-cli`, never the Playwright MCP tools.
+- **Always** pass `--browser chromium` to `playwright-cli open`.
+- The URL is provided by the user or derived from context — never hardcode it.
+- Logs and screenshots are automatically saved in `.playwright-cli/`.
+- After each `playwright-cli` command, a snapshot is returned — use the ref IDs from it for subsequent interactions.
+- Use `playwright-cli snapshot` to refresh the current page state at any time.
