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 | $0.00046 | $0.01462 |
| Opus 5 | $0.00023 | $0.00731 |
| Sonnet 5 | $0.00009 | $0.00292 |
| Haiku 4.5 | $0.00005 | $0.00146 |
Grade A, and why
stitch-mcp-generate-screen-from-text 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 11d 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.

Stitch MCP — Generate Screen from Text
Generates a UI design screen from a structured text prompt. This is the central action in any Stitch workflow — everything before it (spec generation, prompt assembly) is preparation, and everything after it (screen retrieval, code conversion) is follow-through.
Critical prerequisite
Only use this skill when the user explicitly mentions "Stitch" or when called from an upstream skill (e.g. stitch-ideate, stitch-orchestrator).
You must have a projectId before calling this. If you don't have one:
- Create a new project via
stitch-mcp-create-project - Or find an existing project via
stitch-mcp-list-projects
When to use
- User asks to "design", "generate", "create", or "make" a screen using Stitch
- The orchestrator has assembled a prompt via
stitch-ui-prompt-architect - User provides specific visual requirements and wants a Stitch-generated result
Call the MCP tool

"name": "generate_screen_from_text",

"projectId": "3780309359108792857",
"prompt": "[Full structured prompt — see below]",
"deviceType": "MOBILE",

Parameter reference
designSystem — optional, PREFIXED asset id
✅ "assets/15996705518239280238"
❌ "15996705518239280238"
This is how you get design consistency across generated screens — pass the name of a design system from stitch-mcp-create-design-system, stitch-mcp-create-design-system-from-design-md, or stitch-mcp-list-design-systems (used as-is, with the assets/ prefix). This is the opposite format from apply_design_system's assetId, which wants the prefix stripped.
projectId — numeric ID only, no projects/ prefix
✅ "3780309359108792857"
❌ "projects/3780309359108792857"
prompt — use the [Context] [Layout] [Components] structure

What ships with it
2 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.

stitch-mcp-generate-screen-from-text is a skill published in the GitHub repository gabelul/stitch-kit (45 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 46 tokens to every session and 1,462 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
