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 | $0.00030 | $0.01892 |
| Opus 5 | $0.00015 | $0.00946 |
| Sonnet 5 | $0.00006 | $0.00378 |
| Haiku 4.5 | $0.00003 | $0.00189 |
Grade A, and why
stitch-design 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stitch Design
Use this as the entrypoint for Google Stitch work. The old local monolithic Stitch guidance has been consolidated into narrower skills imported from https://github.com/google-labs-code/stitch-skills at commit 7b53207b94e62911777d53d4238b5f8c88c2b519. This file now routes tasks and carries shared safety rules; detailed workflows live in the dedicated stitch-* skills.
When to Use This Skill
- The user asks for Stitch, Google Stitch, Stitch MCP, DESIGN.md, Stitch screen generation, Stitch upload, or Stitch-to-code work.
- The task is unclear and needs routing to the correct Stitch design, build, or utility workflow.
- A previous broad Stitch workflow would have mixed upload, prompt, design-system, code, and video steps in one place.
Route Selection

stitch-extract-static-html |
Capture a self-contained static HTML snapshot from a running app or mock component so it can be reviewed or uploaded to Stitch. |
stitch-upload-to-stitch |
Upload approved local HTML, markdown, or image assets to a Stitch project using direct MCP for small DESIGN.md files or the bundled API script for larger files. |
stitch-react-components |
Convert Stitch HTML and screenshots into modular Vite/React/TypeScript components, or sync existing components to updated Stitch designs, with local architecture and validation checks. |
stitch-react-vite-dashboard |
Convert approved Stitch exports into accessible React and Vite dashboards with DESIGN.md tokens, TanStack Query data boundaries, responsive layouts, and optional read-only Web3 integrations. |

stitch-enhance-prompt |
Transform rough UI requests into structured Stitch prompts with platform, layout, component, and design-system context. |
stitch-loop |
Run an iterative Stitch website-building loop using .stitch/next-prompt.md, SITE.md, DESIGN.md, generated pages, and verification checkpoints. |
stitch-taste-design |
Create opinionated premium DESIGN.md guidance for Stitch, emphasizing calibrated typography, restrained color, layout discipline, motion, and anti-generic UI rules. |
What ships with it
6 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-design is a skill published in the GitHub repository PracticalSwan/agent-skills (14 stars, last pushed 4d ago), licensed MIT. It adds 30 tokens to every session and 1,892 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 2026-09-03.
