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 5.1 | $0.00146 | $0.02273 |
| Opus 5 | $0.00073 | $0.01137 |
| Sonnet 5 | $0.00029 | $0.00455 |
| Haiku 4.5 | $0.00015 | $0.00227 |
Grade A, and why
prd-to-mockup 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 12d 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.

PRD to Mockup — Wireframe Generator
Chuyển Screen States từ Lean PRD thành low-fidelity wireframe dạng HTML. Mỗi screen state = 1 wireframe, liên kết theo workflow diagram.
Triết lý
Wireframe là visual validation cho Business Rules, không phải pixel-perfect design.
Mục đích:
- PM/Stakeholder validate: "đúng, user sẽ thấy như vậy"
- Gen engineer hiểu UI structure trước khi code
- prd-to-gherkin biết
@webscenario cần verify element gì
Wireframe KHÔNG quyết định: màu sắc, font, spacing cụ thể, responsive behavior → đó là việc của designer.
Workflow: Parse → Render → Link
Step 1 — Parse Screen States từ PRD
Khi nhận PRD (lean-prd format), extract:
- Danh sách Screen States — mỗi state = 1 screen
- Workflow diagram — thứ tự screens, navigation flow
- Business Rules per screen — rule nào active tại screen đó
- Data elements — field hiển thị, editable, read-only
- Actions — buttons/links, rule guard cho mỗi action
- Error states — user thấy gì khi rule bị vi phạm
Nếu PRD không có Screen States, hỏi:
"PRD này chưa có Screen States. Bạn mô tả sơ: user nhìn thấy gì ở mỗi bước trong workflow?"
Step 2 — Render Wireframe
Tạo 1 file HTML duy nhất chứa tất cả screens, navigate giữa chúng được.
Nguyên tắc render
Layout:
- Dùng gray boxes, borders, placeholder text
- Không dùng màu sắc (trừ: đỏ cho error state, xanh lá cho success)
- Font: system default, 1 size cho content, 1 size lớn hơn cho heading
- Max width 800px, centered
Elements mapping:
Screen State field → Wireframe element
─────────────────────────────────────────────
Hiển thị (read-only data) → Gray box với label + placeholder value
Có thể sửa (editable) → Input field với border + label
Chỉ đọc (from source) → Gray background input, disabled look
Actions (buttons) → Button với label, annotate guard rule
Khi lỗi (error) → Red border + error message text
Annotations (quan trọng!):
- Mỗi element có annotation nhỏ ghi Rule ID liên quan:
[BR-M01] - Mỗi button ghi guard condition:
[Submit] → requires BR-M01, BR-M02 - Mỗi screen có title = State name từ workflow
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.

prd-to-mockup is a skill published in the GitHub repository cuongtl1992/vibe-skills (10 stars, last pushed 5mo ago), licensed MIT. It adds 146 tokens to every session and 2,273 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
