Start here. Returns the map of everything available: foundations, component catalogue, layout recipes, UX patterns, token groups and export formats, with the tool call needed to retrieve each.

Full-text search across components, foundations, patterns, layouts, tokens, runtime APIs and migration changes. Use when you know what you need but not where it lives.

Complete public behavior API, including exact TypeScript declarations and supporting types. Filter by component id or exported API name; omit id for the full catalogue. Includes automatic selectors, manual initialization, cleanup, events and application responsibilities.

Upgrade to the current release from v2 or v3.0: full canonical plan, source-specific steps, rollout/rollback guidance, behavior changes, compatibility baseline and optional legacy geometry CSS. componentId filters behavior changes; fromVersion selects the upgrade source while preserving the complete guide.

The reasoning behind the system: principles, colour, dark mode, responsive layout, typography, spacing, elevation, motion, accessibility, content and voice, iconography, density, internationalisation, data visualisation, theming. Read the relevant foundation before implementing in that area.

The component catalogue, optionally filtered by category or status.

The complete spec for one component: anatomy, variants, sizes, states, props, tokens consumed, dark-mode behaviour, full accessibility contract (role, keyboard model, ARIA obligations, WCAG criteria, target size), content rules, and do/don't guidance.

Production code for a component in the requested framework. HTML returns reference markup with the required ARIA wiring; CSS returns the production stylesheet written against semantic tokens; framework options return editable reference recipes with native markup and lifecycle wiring. Inspect implementation metadata for dependencies and application responsibilities.

Check component markup, stylesheet dependencies, SVG symbols, ID references, initialization and declared application events. Returns structured findings and fixes; does not execute callbacks.

A complete page blueprint: regions, responsive strategy, accessibility obligations, dark-mode notes, and paste-ready markup plus CSS. All recipes are flex-first and most contain no media query.

A recurring UX problem and the Sekura answer: the problem, the solution, the rules, the accessibility obligations, and the anti-patterns to avoid.

Resolved token values. Filter by group, by name fragment, or return everything. Shows the value in every theme so dark-mode differences are visible side by side.

Emit tokens in a consumable format. Each format documents its supported scopes, projections and consumer verification obligations; CSS is the complete runtime token artifact.

The raw colour ramps behind the semantic layer. Use these to build new semantic tokens or to re-brand. Never reference a primitive from product code — it does not change between themes, so it will not adapt to dark mode.

Describe what you are styling in plain words and get the semantic tokens that apply, with resolved values per theme and a note on why that token rather than a neighbour. Use this instead of guessing a token name or reaching for a hex value.

WCAG 2.2 contrast for the rendered foreground/background pair. Supports hex, transparent, modern rgb() and token names. Composites background over an explicit opaque backdrop, or the disclosed theme base when omitted, then foreground over that background.

Runs every contrast promise the design system makes against one theme or all four. This is the build gate — run it after any palette change. A pairing that is not declared here is not promised and must not be used to carry meaning.

Checks HTML or CSS for the accessibility and design-system failures that actually ship: missing accessible names, unlabelled inputs, hard-coded colours that break in dark mode, flex containers that will overflow, positive tabindex, removed focus outlines, and misused live regions. Advisory — a clean result is not a certificate of accessibility.

Everything needed to start: the HTML scaffold, the pre-paint theme script (which must be inline and synchronous, or you get a flash of the wrong theme), the reset, the utility layer, the prose styles, and the theme control markup.

The entire Sekura stylesheet as one file: tokens for all four themes and three densities, reset, prose, utilities, and every component. This is the single artefact needed to render any Sekura interface.

Absolute URLs for the stylesheet, token files, behaviours bundle and documentation site served by this instance. Use this instead of assuming paths: the server may be mounted under a path prefix, and only it knows what that prefix is.
