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.

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 | $0.00067 | $0.00377 |
| Opus 5 | $0.00034 | $0.00188 |
| Sonnet 5 | $0.00013 | $0.00075 |
| Haiku 4.5 | $0.00007 | $0.00038 |
Grade A, and why
material-ui-tailwind 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 today.
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 and Tailwind CSS
Agent skill for MUI + Tailwind. SKILL.md is the entry; AGENTS.md is the full guide.

- Setting up v4 with Next.js App or Pages Router, or Vite
className/slotProps.*.classNameon MUI components- Mapping
--mui-*variables into Tailwind@theme - Legacy v3 setups or migrations
Sections in AGENTS.md
| Area | Topics |
|---|---|
| v4 | @layer order, mui before utilities |
| Next.js | enableCssLayer, Pages GlobalStyles + shared cache |
| SPA | StyledEngineProvider + enableCssLayer |
| Usage | Root vs slot className |
@theme |
Full snippet on docs site; needs cssVariables |
| IntelliSense | VS Code classRegex |

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.

port-sacred-terminal-ui-to-python
Take a React Window.tsx (or any sacred component) and produce a terminal CLI screen written in Python that uses Simulacrum's Python mirror in scripts/python/sacredcli/. Simulacrum is the sacred CLI framework — the JavaScript half lives in scripts/cli/lib/, the Python half is a one-to-one snakecase mirror.
port-sacred-terminal-ui-to-hostile-react-codebase
Take a sacred React component (or a sacred screen that mirrors a Simulacrum CLI surface) and graft it into a foreign React codebase that already ships its own design system, build pipeline, and CSS toolchain — without breaking the host or polluting it with sacred-specific globals.
