Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00039 | $0.02367 |
| Opus 5 | $0.00019 | $0.01184 |
| Sonnet 5 | $0.00008 | $0.00473 |
| Haiku 4.5 | $0.00004 | $0.00237 |
Grade A, and why
UI Debug Agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to UI Debug Agent — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

UI Debug Agent
Description
Skill chuyên biệt giúp agent inspect ứng dụng web/mobile trực tiếp trên browser thật, phân tích DOM, thu thập locators ổn định, và debug các vấn đề UI automation.
Agent có thể:
- Mở browser thật, navigate đến bất kỳ URL nào
- Inspect DOM elements — xác định attributes, hierarchy, state
- Thu thập locators ổn định cho Playwright, Selenium, Appium
- Debug automation failures (element not found, click intercepted, timeout)
- Capture UI state (snapshot, screenshot) để phân tích
- Phân tích dynamic content, iframe, shadow DOM, SPA navigation
When to Use
Sử dụng skill này khi:
- Cần khám phá UI của một trang web/module mới
- Cần tìm locator cho element cụ thể
- Cần debug test automation fail do UI thay đổi
- Cần verify locator có hoạt động trên DOM thực tế không
- Cần phân tích DOM để hiểu cấu trúc UI (forms, tables, modals)
- Cần capture evidence (screenshot) cho test report
Trigger keywords: "inspect UI", "tìm locator", "debug element", "mở browser xem", "kiểm tra DOM"
MCP Command Sequence (BẮT BUỘC)
Khi sử dụng Playwright MCP để debug UI, LUÔN tuân theo thứ tự:
1. browser_navigate(url) → Mở trang
2. browser_resize(1920, 1080) → Desktop viewport
3. browser_wait_for(text/time) → Chờ page load
4. browser_snapshot() → Thu thập DOM (dùng để phân tích + tìm locator)
5. browser_click/type/hover(ref) → Tương tác (nếu cần)
6. browser_take_screenshot() → Chụp ảnh (evidence khi fail hoặc milestone)
Quy tắc quan trọng:
| Quy tắc | Chi tiết |
|---|---|
| KHÔNG navigate lại nếu đã ở đúng trang | Tránh reload ngoài ý muốn |
| LUÔN resize ngay sau navigate | browser_resize(1920, 1080) — đảm bảo desktop viewport |
| LUÔN wait trước khi snapshot | Chờ page load hoàn tất |
| Dùng snapshot để phân tích | Snapshot trả về accessibility tree — nhanh, chính xác, có ref để tương tác |
| Dùng screenshot để báo cáo | Screenshot là hình ảnh — dùng khi cần evidence visual |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

UI Debug Agent is a skill published in the GitHub repository anhtester/ClaudeCode_Playwright_Demo (2 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 2,367 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to UI Debug Agent, differing in 0 lines, and is treated as a copy.
