Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (8)

`get_component`read-only	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_context`read-only	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_command`read-only	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_blocks`read-only	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_catalog`read-only	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_components`read-only	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_catalog`read-only	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_registry`read-only	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`.

Schemas: list_tools.
