Cronus UI tools (8)

write = sends, deletes, buys or posts
  • get_componentFree

    Fetch the full detail for a single Cronus UI component or block by name: its source file(s) (path + content), its npm `dependencies`, its `registryDependencies` (other registry items it needs), and the `npx cronus-ui add <name>` install command. Works for both components and blocks.

  • get_design_contextFree

    Return the Cronus UI visual taste file (DESIGN.md) for a theme × look. Use this before generating UI so the agent follows Aurora/Neutral dual identity, one primary CTA, hairline elevation, and look rules. compact fits a system prompt; extended is the repo file. Does not modify the project.

  • get_install_commandFree

    Build the `npx cronus-ui add ...` command for one or more components/blocks. The CLI resolves and installs each item's registry dependencies automatically. This only returns the command string — to actually install, use `install_component`.

  • list_blocksFree

    List the installable Cronus UI blocks (registry items of type 'registry:block') — larger, composed sections such as hero, pricing, login, and dashboard. Returns each block's name, title, dependencies, and its `npx cronus-ui add <name>` install command.

  • list_catalogFree

    Return compact Hydra-ready cards for every component, block, variant, and template: name, short description, design style, palette, motion, intents, and the install command. No source files — cheap on tokens. Filter with `kind`. Use `match_catalog` to pick the best item for a prompt (login + smooth animation, etc.).

  • list_componentsFree

    List the installable Cronus UI components (registry items of type 'registry:ui'). Returns each component's name, a readable title, its npm and registry dependencies, and the `npx cronus-ui add <name>` command to install it.

  • match_catalogFree

    Two-query catalog match for low-context agents. Pass a free-text `query` (e.g. 'login page with smooth animation') and/or structured filters (`intent`, `motion`, `style`, `palette`). Returns `pick` (the recommended combination), `intent` hits, `motion` hits, and ranked `matches`. Cards carry description, design style, palette, motion, and intents — not source. Fetch source with `get_component` only after picking a name.

  • search_registryFree

    Fuzzy-search Cronus UI components and blocks by name (case-insensitive substring match). Use this to find the right item before fetching its source with `get_component`.

Cronus UI

Cronus UI is a product UI system — the Cronus design language, a live theme runtime, and a compose path that turns validated blocks into apps. Dual distribution: install @cronus-ui/ui from npm, or copy the source in with the CLI. Canonical start: npx create-cronus-app my-app --template saas.

Aurora is the flagship theme of generated product; Neutral is the docs chrome.

v0.7.6 — OSS at aicronus.com, Cronus Pro at

iacronus.com. Canonical start:

npx create-cronus-app my-app --template saas. See

ADR 0003.
