sandbox

sandbox is a command for Claude Code from memi-design/design-sandbox. It costs 33 tokens per session (374 once invoked), scanned A, original, MIT.

A design-exploration command that turns a brief, screenshot, or Figma design into a temporary web prototype using shadcn components. It can optionally add motion such as animation or transitions.

In plain words
What is it for?
Use it to decode a design reference, scaffold a page at /sandbox, verify it with pnpm typecheck, and optionally explore animation or interaction ideas.
Why use it?
It lets you test a visual idea in a browser before treating it as a finished deliverable. The workflow also checks that the generated project passes a TypeScript type check.

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

sandbox 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.

What it actually says

You are running the design-sandbox pipeline. The user wants to explore a design idea — not ship a deliverable. Iterate freely; defaults can be loose.

The user's input is: $ARGUMENTS

(If a screenshot is attached above this command, treat it as the visual source of truth.)

Pipeline

  1. Decode. Invoke the screenshot-decoder subagent with the input and any attached image/URL. Wait for its structured spec.

  2. Confirm scope with the user. Echo the spec's Brief line + the Open questions. If there are blocking ambiguities, ask them now in one tight AskUserQuestion call before moving on. If there are no blockers, proceed.

  3. Scaffold. Invoke the component-scaffolder subagent with the spec. It will run shadcn add commands and write src/app/sandbox/page.tsx.

  4. Verify it renders. Run pnpm typecheck. If clean, tell the user to open http://localhost:3000/sandbox (and offer to start pnpm dev in the background if not already running).

  5. Motion (optional). If the brief mentions motion, animation, transitions, "feels", "loop", "reveal", or similar — invoke motion-director for one motion pass. Otherwise stop here and wait for the user.

Tone

Terse. One sentence between phases — what just happened and what's next. No commentary.

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.
