check_design

Check a page's HTML/CSS/copy/interaction for the patterns that make AI-generated work read as generic: default fonts, soft tech gradients, pill+arrow buttons, eyebrow labels, a composition with no real width/background variation across sections, uniform card grids, copy tells (AI vocabulary, negative-parallel framing, hedge words, heavy em-dash use), and experience gaps (a diagnosis with no next step, dead-end links).

Inferred read-only
check_copy

Check marketing or outreach copy (an email, a landing-page draft, a pitch, a social post) for the tells that make it read as AI-generated: cliché vocabulary (delve, unlock, empower, seamlessly integrate, etc.

Potential side effects
check_code

Check a source file or diff for AI 'tells' left in comments: narrating fulfilling a request instead of describing the code ("as requested," "I've added," "here's the updated version") and hedge words.

scan_mcp_server

Check an MCP server for real risk signals before trusting it: unauthenticated transport, capability overreach (filesystem/shell/credential access with no scoping), and known-bad signatures.

Potential side effects
scan_content

Check a document or web page for hidden instructions before an agent reads, summarizes, or acts on it: invisible Unicode, obfuscated payloads, and (on Pro) a semantic pass for prompt-injection phrasing aimed at the model instead of the human reader.

Inferred read-only
scan_extension

Check a VS Code extension or a Claude Skill before installing or trusting it.

Inferred read-only
check_output

Check a structured output you're about to return or act on for degenerate-answer patterns a schema check can't see: invalid JSON, a placeholder value ('TBD', 'N/A', 'unknown') where a real answer should be, an array of byte-identical items (a common symptom of a loop that never advanced), or an expected field that's missing or empty.

toolspromptsresources
Server instructions

Checks, expert prompts and reference resources for designers working with AI. Start with the getting_started tool or prompt. Tools do the things models do badly (contrast maths, page accessibility audits, slop signals, lint for feedback, research questions and tracking plans, sample sizes). Prompts give you the method for critiques, heuristic evaluations, accessibility reviews, microcopy, research plans, handoff and more; they say which tools to call and how to use the Figma MCP when given a Figma link. Pro adds site crawls, token matrices, scored reports and playbooks.
