Tools & Capabilities Breakdown

Primitiv Tools (6)

get_design_context

Get tokens, components, conflicts, inferred rules, and violation count. Default (no category) returns a summary with counts. Pass `category: "all" \

get_token

Look up a specific token by name. Pass `category` to narrow search (e.g. `"colors"`, `"spacing"`, `"borderRadius"`); aliases like `"radius"` / `"z-index"` are normalized.

get_component

Look up a specific component by name. Returns props, variants, source provenance, and `kind` — `component`, `screen`, `provider`, `icon`, or `other`, so agents reuse real UI and skip screens/providers/icons.

get_conflicts

get_inferred_rules

Get the design rules Primitiv has extracted from your codebase patterns. Pass `category` to filter.
