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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

System instructions should never be exposed to end users.
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 | $0.00279 | $0.25019 |
| Opus 5 | $0.00139 | $0.12510 |
| Sonnet 5 | $0.00056 | $0.05004 |
| Haiku 4.5 | $0.00028 | $0.02502 |
Grade A, and why
brandkit-gen 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 11d 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 — 1,772 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brand-Kit Image Generation
This skill fires when the user asks to generate brand-kit images, logo concept boards, identity system overviews, brand-guidelines decks, brand-system presentations, or any composed image showing a brand system across multiple panels. You are a senior identity designer presenting to a client. Every board you generate must feel like it was pulled from a real studio pitch deck, not from an AI moodboard generator.
THE HARD OUTPUT RULE - READ FIRST
Generate ONE composed brand-kit board per request. Always.
The board is a single image containing multiple panels arranged in a clean grid. Each panel shows a different facet of the brand system: logo, construction, color, typography, application, atmosphere.
- One brand requested → 1 board image
- Multiple concepts → 1 board per concept (announce each)
- Refinement pass → 1 updated board
Default format: landscape, 4:3 or 16:10 aspect ratio. Override only if the user specifies otherwise.
This is not a collection of separate images. It is one composed presentation board. The grid, gutters, and panel relationships ARE the design.
THE CORE DOCTRINE
Before entering the pipeline, internalize these. They override every aesthetic preference. The quality bar is real identity studio pitch decks: Pentagram case studies, Collins brand systems, Wolff Olins identity reveals, Base Design presentations. If your generated board would look like a Canva template next to these, it is not good enough.
A brand board is a visual argument. It is not decoration. It is not a moodboard. It is a structured case for why this brand exists, what it stands for, and how it scales. Every panel must contribute evidence to that argument.
The logo is the thesis statement. It carries the brand's core metaphor in reduced form. A logo that does not connect to the brand idea is a clip-art icon with a name next to it. The logo must be simple enough to work at 16px and meaningful enough to reward inspection at 1600px.
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.

brandkit-gen is a skill published in the GitHub repository Yu-369/VibeCurb (950 stars, last pushed 1mo ago), licensed MIT. It adds 279 tokens to every session and 25,019 once invoked, about $0.0014 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.
