labs-quickstart

labs-quickstart is a skill for Claude Code, Codex from get-convex/convex-codex-plugin. It costs 146 tokens per session (4,148 once invoked), scanned B, original, no licence file.

A Convex quickstart that creates a running Next.js web app with shadcn components, passkey sign-in, and an in-app Chef feedback panel from a single sentence. Convex is a platform for building app backends, and the quickstart can publish the app to a public web address after you confirm.

In plain words
What is it for?
Use it to scaffold a Next.js app, add WebAuthn passkey login, try the built-in Chef feedback panel, and publish the result to a public Convex address.
Why use it?
It gives you a starting app and lets you develop the idea interactively before making it publicly available.

Token cost

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.

Security

Grade B, and why

labs-quickstart scanned grade B with 2 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 3d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

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.
