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 5.1 | $0.00052 | $0.07342 |
| Opus 5.5 | $0.00021 | $0.02937 |
| Sonnet 5.5 | $0.00010 | $0.01468 |
| Haiku 4.5 | $0.00005 | $0.00734 |
Grade A, and why
design-lab 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 2mo 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.

Design Lab Skill
Source: ui-skills.com.
This skill implements a complete design exploration workflow: interview, generate variations, collect feedback, refine, preview, and finalize.
CRITICAL: Cleanup Behavior
All temporary files MUST be deleted when the process ends, whether by:
- User confirms final design → cleanup, then generate plan
- User aborts/cancels → cleanup immediately, no plan generated
Never leave .claude-design/ or __design_lab routes behind. If the user says "cancel", "abort", "stop", or "nevermind" at any point, confirm and then delete all temporary artifacts.
Phase 0: Preflight Detection
Before starting the interview, automatically detect:
Package Manager
Check for lock files in the project root:
pnpm-lock.yaml→ usepnpmyarn.lock→ useyarnpackage-lock.json→ usenpmbun.lockb→ usebun
Framework Detection
Check for config files:
next.config.jsornext.config.mjsornext.config.ts→ Next.js- Check for
app/directory → App Router - Check for
pages/directory → Pages Router
- Check for
vite.config.jsorvite.config.ts→ Viteremix.config.js→ Remixnuxt.config.jsornuxt.config.ts→ Nuxtastro.config.mjs→ Astro
Styling System Detection
Check package.json dependencies and config files:
tailwind.config.jsortailwind.config.ts→ Tailwind CSS@mui/materialin dependencies → Material UI@chakra-ui/reactin dependencies → Chakra UIantdin dependencies → Ant Designstyled-componentsin dependencies → styled-components@emotion/reactin dependencies → Emotion.cssor.module.cssfiles → CSS Modules
Design Memory Check
Look for existing Design Memory file:
docs/design-memory.mdDESIGN_MEMORY.md.claude-design/design-memory.md
If found, read it and use to prefill defaults and skip redundant questions.
Visual Style Inference (CRITICAL)
DO NOT use generic/predefined styles. Extract visual language from the project:
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.
