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 | $0.00053 | $0.00556 |
| Opus 5.5 | $0.00021 | $0.00222 |
| Sonnet 5.5 | $0.00011 | $0.00111 |
| Haiku 4.5 | $0.00005 | $0.00056 |
Grade A, and why
vibeusage-design 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 1mo 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.
What it actually says
Read the README.md file within this skill, and explore the other available files.
If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy assets out and create static HTML files for the user to view. If working on production code, you can copy assets and read the rules here to become an expert in designing with this brand.
If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.
Quick orientation
- Brand: VibeUsage — Bloomberg terminal × The Matrix. Three words:
hacker · 复古 · cyberpunk. - Pocket color: Matrix Green
#00FF41on#050505. Single gold accent#FFD700reserved for leaderboard #1 / cost. - Font: Geist Mono only (system fallback to ui-monospace). No exceptions.
- Signature: ASCII-frame panel + corner-cross title chip + scanline overlay.
- Drop-in tokens:
colors_and_type.css— covers all colors, type, spacing, shadows, animations. - Hard rules: zero radius on every data surface (only the status dot, avatars, and floating action buttons round — see README §Corner radii), 1px solid borders only, no emoji, uppercase labels, tabular numerals.

Hard "do not" list
- Don't add emoji.
- Don't use
text-[Npx],[#hex],tracking-[Xem],shadow-[…],opacity-30..90,rounded-*,bg-white,text-white. - Don't introduce a third hue for prose / surfaces / accents. Palette ceiling is two ink stops + one gold + neutral surfaces + the warn/err status escape hatch (warn
#FFB300/ err#FF3344, status indicators only). - Don't use bouncy / spring easing. Linear / ease only, 200ms.
- Don't use SaaS rounded cards, gradient headers, or icon-tile grids.
- Don't soften numbers ("~1M"). Show

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.
