Context Cost

~2,490Tokens (tool definitions)
~1.0 KBTypical response size
Moderate attention impact (1.95% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢list_brands_by_node(node)

🟢get_kernel(brand, node)

SPARKS completeness tier for a brand in a market: 100 = resolvable (a real pack/size record is held) . 8 = registered (brand known, pack/size pending) . 'floor' = STANDARD default (no brand-specific record). Returns the stored tier flag — do NOT compute a score. Never returns a pack/size.

Input Schema

{
  "type": "object",
  "properties": {
    "brand": {
      "description": "Brand name as marketed (e.g. Nivea); normalized exact match, fail-closed.",

🟢resolve_sparks(gtin)

Two-branch SPARKS resolver (zero-pads GTIN to 14). Branch A GSC Territory/License GTIN (990832300xxx) -> FULL license record (public). Branch B any third-party BPC GTIN -> GATED proof {recognized, region_node, kernel_available}; the pack/size VALUE is NEVER returned. Route to Navigator. Brand match is fail-closed (normalized exact match); uncertainty -> recognized:false.

Input Schema

{
  "type": "object",
  "properties": {
    "gtin": {
      "description": "GS1 GTIN of the product, 8 to 14 digits; zero-padded to the canonical 14-digit GTIN-14 before lookup (e.g. 00990832300624).",
