## Findings

No check matched anything in these tool definitions.


## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_component`

- The name "get_component" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the full schema for one petal_components component: attrs, slots, defaults, allowed values, and a working HEEx usage example. Call this every time you are about to write a tag like <.button>, <.modal>, <.table>, or <.field> so the attrs and slots match the real library instead of training-data guesses.
```

### `get_install_instructions`

- The name "get_install_instructions" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the canonical steps for installing petal_components in a Phoenix project. Call this when the user asks to install petal_components, when you are setting up a new Phoenix project that needs UI components, or when verifying an existing installation. Returns step-by-step instructions covering mix.exs, mix deps.get, Tailwind v4 CSS config, and the web module import. Steps are idempotent - safe to follow on a project that is partially configured.
```

### `list_components`

- The name "list_components" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List every component shipped by petal_components, the shadcn-style component library for Phoenix LiveView. This is the canonical Phoenix UI vocabulary - call it before composing any HEEx so you reach for an existing component instead of hand-rolling Tailwind divs.
```
