    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 2269 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

Capabilities

Tools 18

audit_search

Whether search engines can index the page and show it well (SEO), answer engines can lift a direct answer (AEO), and AI engines can reach it, read it without JavaScript, and name the entity (GEO): title, description, headings, alt, share card and its 1200×630 image, canonical, robots.txt for search and AI crawlers, sitemap, JSON-LD, question headings with short answers, server-rendered text.

Discovered
audit_slop

Design only: the tells of a generated page (stock copy, em dashes, buzzwords, icon-card trios, gradients, the indigo palette, emoji icons, numbered eyebrows, placeholder copy, made-up numbers) and drift from the locked kit (faces, colours, radius, shadow). Static by default; render=true adds the measured checks.

Discovered
browse_library

List themes, pairings, families, recipes, piece categories, collections, or kinds. Themes and pairings can be ranked by a mood ("warm craft", "editorial serif", "dark technical").

Discovered
check_pick

The uniqueness check from Recent picks: direction, hero, and effect against this recipe; two of hero, work, footer against the related group; hero shape against the last two; frame against the last three. Returns problems and the Unlike line for the sheet.

Discovered
get_family

A family's rules: radius, button style, density, shadow, and the sentences that lock them. The family wins over a brief for radius, shadow, button, and density.

Discovered
get_icons

SVG for Lounge Icons by name (24px, stroke 1.75). With no names, lists them by group. Missing names come back as missing: then follow Icon and nav in components.md, never an emoji.

Discovered
get_pairing

A pairing's CSS (Google Fonts import, --font-display, --font-text, mono if any), its numbers face, and any caution to say before you write.

Discovered
get_piece

The spec for one piece, with a picture of its demo: structure, counts, sizes, motion timing, states, hit targets, acceptance checklist. By default stops at "Optional below this line"; full=true adds the demo's exact paint and motion notes. demo=true adds the demo's HTML source, the acceptance file. Its colours and fonts are the demo's: translate them onto the locked kit.

Discovered
get_recipe

A recipe (start) with its directions: each a complete look (theme, pairing, family, hero, effect, work, footer). Each direction says whether the recent history blocks it.

Discovered
get_theme

A theme's full CSS (primary, secondary, tertiary, feedback, surfaces, link) and its pair for the other mode. Colour only: fonts come from the pairing, radius and shadow from the family.

Discovered
name_number

The tie-break from rule 5 of Pick a direction: the sum of each letter's place in the alphabet, mod the number of fitting directions.

Discovered
pick_direction

Apply rules 3 to 5 of Pick a direction and the Recent picks check: calm words narrow to quiet, editorial, or sharp families; the history blocks recent directions, heroes, and effects; the group check blocks two-of-three matches; the name number breaks the tie. You judge which directions fit the subject (rules 1, 2, 4) and pass them as `fitting`.

Discovered
read_guide

Read a method file or one section of it. Files: SKILL.md, app.md, brief.md, components.md, examples.md, flows.md, locale.md, native.md, practice.md, reference.md, search.md, show.md, styles.md, taste.md, website.md. Give a heading ("Look", "Write the idea", "Recent picks") to get only that section; outline=true lists the headings.

Discovered
review_page

The all-in-one check for a built page: AI giveaways and kit drift (the Look fails), SEO, AEO, GEO, and, when Chromium is available, a rendered pass at 1280×800 and 390×844 with axe accessibility, measured labels, faces, primaries, tap targets, and saved screenshots. Returns scores, fails first, each with its evidence and fix.

Discovered
search_pieces

Search 600+ piece briefs by words (job, component, style, tag) and filters. Returns ids, summaries, and demo links. Then get_piece for the brief.

Discovered
search_wada

Sanzo Wada's 348 combinations, by colour or material word (russet, slate, "dark warm") or nearest to a hex. Only for Free colour, a brand board no theme fits, or colours they asked for. Take one line whole; the header says how to map it to roles.

Discovered
start_design

Call first for any new website, app, screen, or UI. Reads their request the way the method does (flow, mode, named style, calm words), ranks the recipes, reads the project folder and the recent picks, and returns the brief to fill and the steps, each naming the tool to use.

Discovered
suggest_schema

JSON-LD for the page built only from facts on it: the entity (Organization, LocalBusiness subtypes, Person, Product, SoftwareApplication) with name, url, description, image, phone, email, address, sameAs; and FAQPage from its own questions. Lists the fields it could not find. Never invents ratings, reviews, or prices.
