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: 7 findings, 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 →

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 | $0.00046 | $0.01214 |
| Opus 5 | $0.00023 | $0.00607 |
| Sonnet 5 | $0.00009 | $0.00243 |
| Haiku 4.5 | $0.00005 | $0.00121 |
Grade A, and why
v0 scanned grade A with 1 finding 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s https://api.v0.dev/v1/user \ How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vercel v0
v0 is Vercel's AI app builder. Beyond the web UI at
v0.app, it exposes a Platform API (and an OpenAI-compatible model API) so
you can generate UIs, components, and full apps from code.
Hackathon note: participants receive v0 credits. The API bills against those credits, so you can drive v0 from the CLI without a paid upgrade as long as credits remain. Check usage at v0.app/settings/billing.
There are two distinct surfaces — pick the right one:
| Surface | Package / endpoint | Use it for |
|---|---|---|
| Platform API | v0-sdk (npm), https://api.v0.dev/v1 |
Create/iterate chats that return generated files, demos, and deployable projects. This is the real "v0 builds my app" surface. |
| Model API | AI SDK @ai-sdk/vercel, https://api.v0.dev/v1 (OpenAI-compatible) |
Use v0's models (v0-1.5-md, etc.) as a chat/completions model inside your own app. |
Setup (do this first)
- Get an API key — v0.app/settings/keys. The key grants full access to the v0 account — treat it as a secret.
- Store it as an env var, never in code or flags. Add to
.env(gitignored):
The SDK and CLI readecho 'V0_API_KEY=your-v0-api-key' >> .envV0_API_KEYautomatically. - Verify access:
A JSON user object means the key works.curl -s https://api.v0.dev/v1/user \ -H "Authorization: Bearer $V0_API_KEY" | head401means the key is wrong or credits/billing aren't enabled on the account.
Fastest path: scaffold a v0-powered app
# Spins up a Next.js app pre-wired to the v0 Platform API
pnpm create v0-sdk-app@latest my-v0-app
# or: npx create-v0-sdk-app@latest my-v0-app
Platform API via the SDK (generate UI from a prompt)
pnpm add v0-sdk # or: npm install v0-sdk
import { v0 } from 'v0-sdk' // reads V0_API_KEY from the environment
// Create a chat — v0 generates the app and returns a live demo + files
const chat = await v0.chats.create({
message: 'Build a landing page for a biotech hackathon with a hero and signup form',
})
console.log('Preview:', chat.demo) // hosted preview URL
console.log('Chat:', chat.url) // open/iterate in the v0 web UI
// chat.files[] holds the generated source files
// Iterate on the same chat
const next = await v0.chats.sendMessage({
chatId: chat.id,
message: 'Make the hero dark mode and add a pricing section',
})
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.

v0 is a skill published in the GitHub repository Elnora-AI/elnora-ai-agent-hackathon-starter-kit (22 stars, last pushed yesterday), licensed Apache-2.0. It adds 46 tokens to every session and 1,214 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
