## Overview

| Attribute | Value |
|-----------|-------|
| Feature ID | FEATURE-030-B |
| Feature Title | UIUX Reference Agent Skill & Toolbar |
| Total Test Cases | 16 |
| Priority | P0 (Critical) / P1 (High) / P2 (Medium) |
| Target URL | https://www.baidu.com/ (external site — no style conflicts) |

**Note:** FEATURE-030-B's UI is an **injected toolbar** — a self-contained IIFE injected into any page via `evaluate_script`. Agent-side ACs (AC-1–5, AC-24, AC-26, AC-28–32) test agent behavior and are not testable via browser UI; they are documented as N/A below. Testable ACs cover the toolbar UI interactions (AC-6–23, AC-25, AC-27, AC-33–35).

**Non-Testable ACs (Agent-Side):**

| AC | Reason |
|----|--------|
| AC-1–5 | Page navigation/auth — agent skill logic, not toolbar UI |
| AC-24 | `Runtime.addBinding` registration — agent-side CDP call |
| AC-26 | CDP event receipt — agent-side event handling |
| AC-28 | Fallback activation — agent decision logic |
| AC-29 | Reference data construction — agent data processing |
| AC-30–32 | Data persistence/screenshots/reporting — agent + MCP server |

---

## Prerequisites

- [x] Feature is deployed (toolbar JS file exists at `src/x_ipe/static/js/injected/xipe-toolbar.js`)
- [x] Test environment is ready (Chrome open with page loaded)
- [x] Chrome DevTools MCP is available

---

## Toolbar Injection Method

Before each test, inject the toolbar by reading `xipe-toolbar.js` and executing it via `evaluate_script`:

```
1. Navigate to any page (e.g., http://127.0.0.1:5959/)
2. Read toolbar JS from src/x_ipe/static/js/injected/xipe-toolbar.js
3. Execute via evaluate_script: () => { <toolbar IIFE code> }
4. Verify injection: evaluate_script: () => window.__xipeToolbarInjected === true
```

**Acceptance Criteria Reference:** AC-9, AC-33, AC-34 from specification.md

**Priority:** P1

**Preconditions:**
- Toolbar injected, panel open

**Test Steps:**

| Step | Action | Element Selector | Input Data | Expected Result |
|------|--------|------------------|------------|-----------------|
| 1 | Open panel | `#xipe-hamburger` | - | Panel visible |
| 2 | Take screenshot of toolbar | Screenshot of `#xipe-panel` parent | - | Capture toolbar rendering |

| 4 | Take screenshot of mockup | Screenshot of mockup page | - | Capture mockup rendering |
| 5 | Visual compare | Compare screenshots | - | Layout structure, colors, typography match |

**Expected Outcome:** Toolbar visual appearance matches the approved mockup (injected-toolbar-v2.html).

**Mockup Reference:** `x-ipe-docs/requirements/FEATURE-030-B/mockups/injected-toolbar-v2.html` (status: current)

**Status:** ✅ Pass

**Execution Notes:** Toolbar rendered on Baidu homepage and search results page. Visual comparison with mockup v2 confirms: header with logo dot + title, phase separators, 4 tool cards with icons/descriptions/badges, collected references section, green send button. Layout, colors, typography all consistent with approved mockup. Minor: icons depend on CDN (Bootstrap Icons) — loaded successfully on both test pages.(s) Detected

The following mockup(s) are outdated and were NOT used for UI/UX validation:
- `injected-toolbar-v1.html` — Dark glassmorphism alternative (status: outdated)

Consider updating mockups to enable visual comparison in future acceptance tests.

## Notes

- Toolbar is injected via evaluate_script, not hosted at a specific page — tests use http://127.0.0.1:5959/ as a host page
- Agent-side ACs (AC-1–5, AC-24, AC-26, AC-28–32) are not testable via browser UI
- Mockup v1 (dark) is outdated — only v2 (light) used for visual validation
