Material UI is a React component library that provides an independent implementation of Google's Material Design system. Developers use it to build interfaces from reusable React components, with additional advanced components available through MUI X. The catalogue add-ons provide project-specific skills and instructions for working with Material UI.
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 | $0.00052 | $0.00356 |
| Opus 5.5 | $0.00021 | $0.00142 |
| Sonnet 5.5 | $0.00010 | $0.00071 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
material-ui-styling 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
Material UI styling
Agent skill for picking the correct styling layer in Material UI (narrowest scope first). SKILL.md is the entry and index; AGENTS.md is the full guide.
When to apply
- Choosing among
sx,styled(), themecomponents, or global CSS for a change - Overriding component slots or state safely
- Comparing
sxvsstyled()semantics (spacing, theme shortcuts)
Sections in AGENTS.md (by priority)
| Order | Topic | Scope |
|---|---|---|
| 1 | Quick decision | Pick sx → styled → theme → global |
| 2 | sx prop |
One-off / local |
| 3 | styled() |
Reusable wrapper |
| 4 | createTheme({ components }) |
All instances |
| 5 | GlobalStyles / CssBaseline |
HTML baseline / globals |
| 6 | sx vs styled() table |
Foot-gun prevention |

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
