design-verify-web

design-verify-web is a skill for Claude Code from joi-fairshare/agentic-workflow. It costs 35 tokens per session (5,553 once invoked), scanned A, original, no licence file.

A web-design checking skill that uses Playwright, a browser-testing tool, to capture pages at phone, tablet, and desktop sizes and compare them with a reference mockup.

In plain words
What is it for?
It helps check responsive layouts and report mismatches with suggestions for correcting them.
Why use it?
It finds visual differences between an implemented webpage and the intended design, so layout problems do not have to be spotted by hand.

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.

Security

Grade A, and why

design-verify-web 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 6d 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.

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.
