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 | $0.00091 | $0.00770 |
| Opus 5.5 | $0.00036 | $0.00308 |
| Sonnet 5.5 | $0.00018 | $0.00154 |
| Haiku 4.5 | $0.00009 | $0.00077 |
Grade A, and why
generating-stitch-screens 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 yesterday.
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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generating Stitch Screens
Orchestrate screen generation in Google Stitch using MCP tools. Reads authored prompt files, sends each section to Stitch for generation, and fetches resulting images and code.
Prerequisites
Requires Stitch MCP server (@_davideast/stitch-mcp). If MCP tools are not available, display:
Stitch MCP is not configured.
Run /stitch-setup for guided setup, or see the plugin README for manual configuration.
Never fail silently. Always inform the user if MCP is unavailable.
Typically invoked via /stitch-generate or after prompt authoring with MCP available.
Quick Start
- Read prompt file from
design-intent/google-stitch/{feature}/prompt-v{N}.md - Parse sections by
---separators, extracting<!-- Layout: -->and<!-- Component: -->markers - Create or select project via MCP (
create_project/list_projects) - Generate screens — for each section: call
generate_screen_from_textwith prompt text - Fetch images — for each screen: call
fetch_screen_imageat full resolution, save to{feature}/exports/(see WORKFLOW.md for URL transformation) - Fetch code (optional) — call
fetch_screen_code, save to{feature}/code/ - Extract design context (optional) — call
extract_design_context, save design DNA - Report — project URL, screen list, file paths
Output Structure
design-intent/google-stitch/{feature}/
├── prompt-v{N}.md <- Source prompts
├── exports/ <- Generated images
│ ├── {layout-name}.png
│ ├── {component-1}.png
│ └── {component-2}.png
├── code/ <- Generated code (optional)
│ ├── {layout-name}/
│ └── {component-1}/
└── design-dna.md <- Extracted design context (optional)
Section Parsing
Prompt files use --- separators with HTML comment labels:
<!-- Layout: Analytics Dashboard -->
[layout prompt text]
---
<!-- Component: KPI Metrics -->
[component prompt text]
---
<!-- Component: Revenue Chart -->
[component prompt text]
What ships with it
3 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.

generating-stitch-screens is a skill published in the GitHub repository joaquimscosta/arkhe-claude-plugins (21 stars, last pushed yesterday), licensed MIT. It adds 91 tokens to every session and 770 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-10-16.
