## MCP tools (5)

### `roast_get_context` (~59 tokens)

Design-system context before writing UI in this repo: tokens, canonical components, duplicates, spacing and type rules, from a real scan. Optional path ("packages/ui") narrows the slice.

Input parameters:

- `path` (string): Repo-relative folder (optional)

### `roast_find_component` (~58 tokens)

Find the canonical component for a name or intent ("icon button"). Returns import path, usage count and a real usage example, or an honest zero. Ties are reported, never guessed.

Input parameters:

- `query` (string, required): Component name or intent

### `roast_find_token` (~49 tokens)

Snap a raw value (#111111, 13px) to this repo's nearest token or scale step. Says so when no scale exists.

Input parameters:

- `value` (string, required): Colour or length value

### `roast_validate` (~65 tokens)

Check code before saving: hardcoded colours, near-token twins, off-scale spacing, arbitrary brackets, inline styles, !important, duplicate components. Findings name the fix.

Input parameters:

- `code` (string, required): The code to check
- `file` (string): Intended file path (optional)

### `roast_review` (~42 tokens)

Review the working tree's changed files (git diff + untracked) against the design system. Reads the diff itself; send no code. Call before finishing UI work.
