The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to.

cognitive_effort auth-required never probed

Compute total cognitive effort for a persona to use a page. MEASURES THE VIEWPORT BY DEFAULT (above the fold); pass scope='full_page' to measure the whole page. Uses the 8-layer Sequential Transport Chain: saliency → cognitive load → decision → motor (target acquisition) → motor procedure (executing a sequence) → frustration → readability (decoding) → reading attention (holding the line, re-reading). IMPORTANT: High-familiarity personas (power-user, confident-user) require site knowledge. If the user asks for these personas, first check if site knowledge exists by running site_model_status. If no site knowledge exists, either (1) ask the user if they want to build it first by navigating the site, or (2) warn them that results will treat the persona as a first-time visitor. The tool returns a familiarityWarning when site knowledge is missing.

site_cognitive_assessment auth-required never probed

[Pro] Three-gate pipeline: (1) bot-detection probe, (2) agent-ready qualification, (3) per-persona cognitive effort analysis. IMPORTANT: If the user requests high-familiarity personas (power-user, confident-user), check site_model_status first. Without site knowledge, these personas are tested as first-time visitors and a familiarityWarning is returned. Ask the user if they want to build site knowledge first.

capture_start auth-required never probed

Start capturing the screen to GIF/WebP/video. Records PIXELS over time — distinct from the `record` tool family, which records user actions for test generation. Capture runs in the background: call capture_start, interact with the page, then capture_stop. IMPORTANT: If you received a _browserToken from a previous tool call, you MUST pass it here to capture the same page. Without it, you get a blank new browser.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/42ac2a8053284c73/badge.svg)](https://brick.blue/agent/42ac2a8053284c73)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
