vibes

vibes is a skill for Claude Code from popmechanic/VibesOS. It costs 65 tokens per session (2,746 once invoked), scanned A, original, MIT.

A generator for React web applications, which are websites built from reusable interface components. It uses TinyBase, a small reactive data store, to keep app data synchronized as it changes.

In plain words
What is it for?
Use it to create new web apps, add components, or build single-page apps with real-time data. It can also guide optional AI features and deployment.
Why use it?
It gives a defined workflow for creating app interfaces and handling changing data without designing the structure from scratch.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 A, and why

vibes 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 10d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (modules/editor-animations.js, modules/editor-color-utils.js, modules/editor-imggen.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Vibes DIY App Generator

Generate React web applications using TinyBase for reactive data with real-time sync.

Auth Check (silent — only prompt if needed)

Before asking Terminal or Editor, check for cached auth:

VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
bun --input-type=module -e "
import { readCachedTokens, isTokenExpired } from '$VIBES_ROOT/scripts/lib/cli-auth.js';
const tokens = readCachedTokens();
if (tokens && !isTokenExpired(tokens.expiresAt)) {
  console.log('AUTH_OK');
} else {
  console.log('AUTH_NEEDED');
}

Changes

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.
