Tools & capabilities
Primitiv tools 6
get_design_contextGet tokens, components, conflicts, inferred rules, and violation count. Default (no category) returns a summary with counts. Pass `category: "all" \get_tokenLook up a specific token by name. Pass `category` to narrow search (e.g. `"colors"`, `"spacing"`, `"borderRadius"`); aliases like `"radius"` / `"z-index"` are normalized.get_componentLook 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_conflictsGet conflicts between sources. Pass `type: "all" \get_inferred_rulesGet the design rules Primitiv has extracted from your codebase patterns. Pass `category` to filter.get_violationsList token-misuse violations — hardcoded literals in source that bypass the contract, with a suggested token when one fits. Pass `category: "all" \
