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

skill 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 4d 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.

name: cozy-ui-reference

description: Build, review, or modify Cozy applications with cozy-ui React components, Material-UI v4 based theming, Cozy design patterns, CSS utility classes, icons, and component APIs. Use when Codex needs to choose cozy-ui components, write imports from cozy-ui, apply Cozy styling utilities, or answer implementation questions about cozy-ui.

Cozy UI

Use this skill to build Cozy application interfaces with cozy-ui. Prefer this skill over generic React or Material-UI guidance when the task concerns Cozy apps, Cozy UI components, Cozy CSS utilities, or the Cozy theme.

Quick Start

import { Button, Alert } from 'cozy-ui/transpiled/react'
import { CozyTheme } from 'cozy-ui/transpiled/react/providers/CozyTheme'
import 'cozy-ui/transpiled/react/stylesheet.css'

<CozyTheme variant="light">
  <Alert severity="info">Ready</Alert>
  <Button label="Continue" />
</CozyTheme>

What This Skill Provides

  • {{componentCount}}+ React components with examples and extracted props.
  • CSS utility classes for spacing, typography, colors, layout, and component-specific classes.
  • Cozy theming conventions built on Material-UI v4.
  • Import patterns for cozy-ui/transpiled/react and cozy-ui/dist.

Quick Reference

Components

Read references/components.md when choosing a component, checking props, or looking for usage examples.

Common starting points:

  • Buttons and actions: Button, Buttons, IconButton, ActionsMenu, ActionsBar.
  • Forms: TextField, SelectBox, Checkbox, Radios, Switch, SearchBar, FileInput.
  • Layout: Stack, Grid, Paper, Card, Container, Divider.
  • Feedback: Alert, Banner, Snackbar, Spinner, Skeletons, ProgressionBanner.
  • Dialogs and menus: CozyDialogs, Dialog, Menu, ActionsMenu.

CSS Utilities

Read references/css-classes.md when using utility classes or legacy CSS patterns.

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.
