Capabilities

Tools 11

compose_page

Plan a page from blocks for an intent such as 'SaaS landing page with pricing and FAQ' or 'login screen'. Returns one block per section in page order, the install command, a page.tsx scaffold that renders them, and whole templates that already fit. Free blocks only unless includePro is true.

Discovered
get_changes

When an item was added and last changed, and the library releases since a date or version you pass. Call it before updating an installed item: `since` is when the user installed it (YYYY-MM-DD) or the library version they have.

Discovered
get_examples

Working example code for an item: the demos shown on its page, with imports pointing where the CLI installs the item. Use it to wire an item up the way it is meant to be used.

Discovered
get_install_command

The exact shadcn CLI command that installs an item, for npm, pnpm, yarn or bun. Run it in the project's root.

Discovered
get_item

Everything about one item: description, props, a usage example, dependencies, accessibility notes, quality checks, docs URL, registry JSON URL and install command.

Discovered
get_quality_rules

The accessibility, motion, theming and SSR rules every item follows, with why each matters and how to meet it. Read them before writing UI so the first draft already passes.

Discovered
get_setup

How to prepare a project for this library: requirements, shadcn init, where files land, themes, dark mode and the Pro registry entry.

Discovered
get_tests

The Vitest and Testing Library tests that ship with an item (keyboard use, states, ARIA), with the packages they need. Use them to check an item still works after you or the user changed it. Returns shipped: false when the item has no tests.

Discovered
list_categories

How many components, charts, blocks, templates, patterns and hooks exist, and the categories each is grouped into, with counts. Use a category name as the filter of list_items.

Discovered
list_items

List items, optionally filtered by category (a name from list_categories) and type.

Discovered
search_items

Search components, charts, blocks, templates, patterns and hooks by what you need, for example 'date picker', 'pricing section', 'stacked bar chart', 'modal', 'confirm before delete' or 'debounce'. Common synonyms are understood. Returns the best matches with install commands.
