We build the checks agents run on themselves.
Small, focused tools: each one either catches a real problem before it ships, or gives an agency one dashboard instead of twenty logins.
Preflight
MCP security
Check it before your agent trusts it.
Scans an MCP server or a page/document for unauthenticated transport, capability overreach, and injected instructions aimed at the model, before your agent trusts either one.
Design Check
Design critique
Does it read as AI-generated?
Checks a page's layout, typography, and copy against the patterns that make AI-built work look and sound generic, before you ship it, not after a reviewer flags it.
Vantage
SEO reporting
Every client's Search Console, one dashboard.
A reporting console built for agencies running search for more than one client: no more logging into each property's Search Console separately.
Bearing
Meta Ads reporting
Every client's ad account, one dashboard.
Sits above Meta Ads Manager for agencies running more than one client's spend: every account's results and what needs attention, on one screen instead of switching Business Managers.
Pulse
Core Web Vitals
Real field data, not a lab guess.
Checks a page against Google's actual ranking-signal data (Chrome UX Report, real visitors) and a live Lighthouse run, then says plainly whether it passes. Free, no signup.
Verdict
Design review
A design review before the design ships.
Six review tools an agent can call on a screenshot, a flow or a spec: hierarchy, copy, states, accessibility, the AI-generated tells, and a verdict with the fix list. Bring your own Anthropic key or take Pro.
Toolbox
Small tools
Fourteen mundane jobs, done properly.
AI-writing tells, the token cost of an MCP tool list, CLAUDE.md lint, install snippets, AI-crawler policy, security headers, page meta, JSON to schema, cron, an env scrubber, a redirect tracer, a sitemap check, an MCP tool-definition lint and a JWT decoder. Free, no signup.
Designers
For designers using AI
The parts of design your AI gets wrong, done properly.
Connect one web address to Claude, Cursor, VS Code, Codex or ChatGPT and it can check contrast exactly, audit a page for accessibility, run a Nielsen heuristic evaluation, spot generic AI design and writing, plan research and critiques, and write handoff specs. Thirteen free skills to match. Works with a Figma link; nothing to install.
Design Skills
Design skills
Thirteen free skills, no signup.
Design critique, accessibility review, Nielsen heuristics, an anti-slop check, UX writing, research plans, and seven more. Install the plugin in Claude Code or copy one skill folder into your own project, then point it at a screenshot, a flow, or a PRD.
Preflight and Design Check share the same mechanic: an agent calls a check before it ships or trusts something, and gets told what's wrong before a person ever sees it. Vantage runs on a different clock: real subscription revenue for a real buyer, an SEO agency, while the agent-tooling side builds an audience.
