55Look up any event a [mod](/docs/en/plugins/mods/overview) can handle, mods API method it can call, or render site it can draw in. Entries cover the Claude Code CLI and the Desktop app as of v2.1.290, and the VS Code extension as of v2.1.299. Each entry gives the name and a one-line description, and links to the guide section that explains it where there is one.

8987In a `skill.prompt` hook, you can read these fields along with the skill's name in `e.skill` and the text Claude reads in `e.text`:

277### `Box` border styles
284278
285279To draw a border around a `Box`, set its `borderStyle` to one of these names, as in `borderStyle: 'round'`. Each row says what the terminal draws for that name and shows the top edge of the border.

305297
306298The `Box` spacing props are `gap`, `columnGap`, `rowGap`, `padding`, `margin`, and the one-side and one-axis forms of `padding` and `margin`, such as `paddingX` and `marginTop`. Each takes a number of terminal cells such as `gap: 1`, or a step name such as `gap: 'md'`. In the terminal and the VS Code extension, each step is this many cells:

318310Step names require Claude Code v2.1.299 or later. On an earlier release, Claude Code [draws its own version of the site](/docs/en/plugins/mods/interface#build-a-tree-from-elements) in place of a tree that uses a step name.

312### `Text` typography props
323313
324314Set `size`, `weight`, `mono`, or `tabular` on a `Text` to ask the app drawing your tree for a text size, a weight, a monospaced typeface, or equal-width digits. Before you rely on a prop, check what the terminal and the VS Code extension do with it. If an app ignores a prop you set, your tree still draws there, with the text as if you'd left that prop out.

333323These four props require Claude Code v2.1.299 or later. On an earlier release, Claude Code [draws its own version of the site](/docs/en/plugins/mods/interface#build-a-tree-from-elements) in place of a tree that sets `size`, `weight`, `mono`, or `tabular`.

339327`bold` on a `Text` is deprecated in favor of `weight` and still works. To replace it on a `Text` with no `weight`, change `bold: true` to `weight: 'semibold'` for the same result on Claude Code v2.1.299 or later.
