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.

What it costs to keep this loaded
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 | $0.00093 | $0.08877 |
| Opus 5 | $0.00046 | $0.04438 |
| Sonnet 5 | $0.00019 | $0.01775 |
| Haiku 4.5 | $0.00009 | $0.00888 |
Grade A, and why
pixel-perfect-replication 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 901 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pixel-Perfect Design Replication
This skill fires when the user provides a screenshot, mockup, Figma export, or any design image and asks you to replicate it in code. The reference image is the specification. Your role is translator, not designer. Every visual decision - font size, spacing, color, radius, shadow, layout proportion - comes from the image, not from your preferences.
The Pipeline
Every replication job follows this flow. No phase can be skipped. No phase can start before the previous one completes.

Phase 1: Image Intake
Receive the reference image. Before doing anything else, classify what you are looking at.
→ Classify the image
Fill in this table for every reference image:
| Field | Your answer |
|---|---|
| Image type | Full-page screenshot / single section / component detail / mobile view / desktop view / Figma frame / design tool export / live site screenshot |
| Sections visible | List top-to-bottom, e.g. "Nav → Hero → Features → Testimonials → Footer" |
| Target viewport | Estimated width: 1440px (desktop), 1280px (laptop), 768px (tablet), 375px (mobile) |
| Fidelity | High-res export (sub-pixel details are intentional) / compressed screenshot (some lossy artifacts) |
| Theme | Light / Dark / Mixed |
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.

pixel-perfect-replication is a skill published in the GitHub repository Yu-369/VibeCurb (945 stars, last pushed 1mo ago), licensed MIT. It adds 93 tokens to every session and 8,877 once invoked, about $0.0005 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 2026-08-30.
