A design generator that creates new user-interface concepts from text prompts and exports HTML, Tailwind code, screenshots, and handoff notes.

Use it to explore original UI directions and pass the resulting design materials to an implementation workflow.

It gives teams a visual starting point when designing a new interface from a written idea.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.01549
Opus 5.5	$0.00021	$0.00620
Sonnet 5.5	$0.00011	$0.00310
Haiku 4.5	$0.00005	$0.00155

Security

Grade A, and why

mk:stitch 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.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/stitch-api-call.ts, scripts/stitch-quota.ts, scripts/stitch-write-output.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stitch — AI Design Generation

Generate high-fidelity UI designs from text prompts. Export Tailwind/HTML, PNG screenshot, and DESIGN.md for handoff to mk:frontend-design.

Use only for a novel, text-prompt design. Existing design sources belong to mk:figma or mk:frontend-design.

Setup and guard

Set STITCH_API_KEY in the project env file, then install the scripts once:

cd .claude/skills/stitch/scripts && npm install

Run the prerequisite check before any API command; it fails before a network request if the key or tsx is unavailable. Full setup, optional variables, and MCP setup: references/stitch-setup.md.

Fail-Closed Gate

Before any script runs, verify both prerequisites:

# Key gate
[ -z "$STITCH_API_KEY" ] && { echo "[X] STITCH_API_KEY not set — add it to the project env file"; exit 1; }

# tsx gate
npx tsx --version 2>/dev/null || { echo "[X] tsx not found — run: cd .claude/skills/stitch/scripts && npm install"; exit 1; }

stitch-api-call.ts also checks STITCH_API_KEY as its first action before any Stitch SDK call. If the key is unset the script exits 1 immediately — no network request is made.

Quick Start

# 1. Check quota
npx tsx .claude/skills/stitch/scripts/stitch-quota.ts check

# 2. Generate (API call only — returns JSON with screenId + imageUrl)
npx tsx .claude/skills/stitch/scripts/stitch-api-call.ts \
  generate "A checkout page with cart summary and payment form"

# 3. Export + write files (pipe: API call → schema-validate → write to disk)
npx tsx .claude/skills/stitch/scripts/stitch-api-call.ts export <screen-id> | \
  npx tsx .claude/skills/stitch/scripts/stitch-write-output.ts

Commands

Task	Command / contract
Check quota	`npx tsx .claude/skills/stitch/scripts/stitch-quota.ts check`
Generate	`npx tsx .claude/skills/stitch/scripts/stitch-api-call.ts generate "<prompt>"` — returns `screenId`, `projectId`, `imageUrl`, and quota data
Export	`npx tsx .claude/skills/stitch/scripts/stitch-api-call.ts export <screen-id> \| npx tsx .claude/skills/stitch/scripts/stitch-write-output.ts`

What ships with it

10 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.

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.
