A workflow for bringing Google Stitch designs into local code while recording their colors, fonts, themes, and component styles in a design.md file. Google Stitch is a design-to-code tool.

Use it to export Stitch design systems, build pages from them, compare a design with a screenshot, or convert the result to ShadCN components.

It gives coding agents a written design reference to follow when building pages or converting designs into reusable interface components.

omk-stitch — Skill for Claude Code and Codex by KaimingWan/oh-my-kiro

Install

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.

Any agent

npx skills add KaimingWan/oh-my-kiro --skill omk-stitch

Clone the repo

git clone --depth 1 https://github.com/KaimingWan/oh-my-kiro

Made for: Claude Code, Codex.

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	$0.00103	$0.02179
Opus 5.5	$0.00041	$0.00872
Sonnet 5.5	$0.00021	$0.00436
Haiku 4.5	$0.00010	$0.00218

Security

Grade A, and why

omk-stitch scanned grade A with 1 finding 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 1mo 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.

Google Stitch Integration Skill

Core Concept: design.md

Stitch's design system is captured in a design.md file — colors, fonts, themes, component styles. This file is:

Agent-optimized — uses targeted language agents understand better than raw CSS
Transferable — give it to Claude Code, Cursor, or any agent and they reproduce the style perfectly
Auto-created — Stitch generates one for every project, even if you don't ask

Default workflow: Always start by establishing a design.md, then build pages on top of it.

MCP Server

Community package: davideast/stitch-mcp npm: @_davideast/stitch-mcp

Setup

Prerequisites

Google Cloud CLI (gcloud) installed
A GCP project with Stitch API enabled

Authentication (OAuth — API Key is NOT supported)

gcloud auth login
gcloud auth application-default login
gcloud config set project <YOUR_PROJECT_ID>
gcloud auth application-default set-quota-project <YOUR_PROJECT_ID>
gcloud beta services mcp enable stitch.googleapis.com --project=<YOUR_PROJECT_ID>

MCP Config

Add to your MCP client config (e.g. .kiro/settings/mcp.json):

{
  "stitch": {
    "command": "npx",
    "args": ["@_davideast/stitch-mcp", "proxy"],
    "env": {
      "STITCH_USE_SYSTEM_GCLOUD": "1",
      "GOOGLE_CLOUD_PROJECT": "<YOUR_PROJECT_ID>"
    }
  }
}

CRITICAL: Must use proxy mode + STITCH_USE_SYSTEM_GCLOUD=1. Direct serverUrl mode is unstable.

Verify Setup

npx @_davideast/stitch-mcp doctor

If doctor times out on API test, verify directly:

ACCESS_TOKEN=$(gcloud auth application-default print-access-token)
curl -s -w "\nHTTP:%{http_code}" \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -H "x-goog-user-project: <YOUR_PROJECT_ID>" \
  "https://stitch.googleapis.com/v1/projects"

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.

omk-stitch is a skill published in the GitHub repository KaimingWan/oh-my-kiro (107 stars, last pushed 6mo ago), licensed MIT. It adds 103 tokens to every session and 2,179 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
