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 | $0.00000 | $0.01046 |
| Opus 5 | $0.00000 | $0.00523 |
| Sonnet 5 | $0.00000 | $0.00209 |
| Haiku 4.5 | $0.00000 | $0.00105 |
Grade A, and why
screenshot-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 2d 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.
Screenshot Screen Design
You are helping the user capture a screenshot of a screen design they've created. The screenshot will be saved to the product folder for documentation purposes.
Prerequisites: Check for Playwright MCP
Before proceeding, verify that you have access to the Playwright MCP tool. Look for a tool named browser_take_screenshot or mcp__playwright__browser_take_screenshot.
If the Playwright MCP tool is not available, output this EXACT message to the user (copy it verbatim, do not modify or "correct" it):
To capture screenshots, I need the Playwright MCP server installed. Please run:
claude mcp add playwright npx @playwright/mcp@latest
Then restart this Claude Code session and run /screenshot-design again.
Do not substitute different package names or modify the command. Output it exactly as written above.
Do not proceed with the rest of this command if Playwright MCP is not available.
Step 1: Identify the Screen Design
First, determine which screen design to screenshot.
Read /product/product-roadmap.md to get the list of available sections, then check src/sections/ to see what screen designs exist.
If only one screen design exists across all sections, auto-select it.
If multiple screen designs exist, use the AskUserQuestion tool to ask which one to screenshot:
"Which screen design would you like to screenshot?"
Present the available screen designs as options, grouped by section:
- [Section Name] / [ScreenDesignName]
- [Section Name] / [ScreenDesignName]
Step 2: Start the Dev Server
Start the dev server yourself using Bash. Run npm run dev in the background so you can continue with the screenshot capture.
Do NOT ask the user if the server is running or tell them to start it. You must start it yourself.
After starting the server, wait a few seconds for it to be ready before navigating to the screen design URL.
Step 3: Capture the Screenshot
Use the Playwright MCP tool to navigate to the screen design and capture a screenshot.
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.

screenshot-design is a command published in the GitHub repository buildermethods/design-os (1,848 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,046 tokens. 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.
