search_products_batch

Read-onlyIdempotent

Search for a whole shopping list in one call: up to 10 queries, each with the search_products filters (5 results each by default). Delivery is free anywhere in Singapore with no minimum spend, so prices shown are delivered prices. Then start_checkout with the chosen variant_ids.

Input Schema

NameRequiredDescriptionDefault
queriesYesOne entry per shopping-list item (up to 10), e.g. [{"q": "rice 5kg"}, {"q": "dishwashing liquid", "max_price": 600}]. Each takes the search_products filters.
guest_tokenNoOptional. Your guest_token from create_cart, if you have one, so this lookup belongs to your shopping session. Not needed to search or read products.

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly, idempotent and openWorld, so the burden is lighter. The description adds genuinely useful non-obvious context: delivery is free anywhere in Singapore with no minimum spend, so listed prices are delivered prices — information that affects how an agent interprets results and compares across queries.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences, front-loaded with the core capability, then the cost/pricing caveat, then the follow-up action. Nothing is repeated or padding.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers what the tool does, its batching limits, the free-delivery/pricing implication, and the next step in the workflow. Return shape is left to the schema (which is rich) and there is no output schema, so the description is nearly complete, though it could mention result ordering or failure behavior across mixed queries.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and every parameter (q, sort, brand, limit, max_price, guest_token, etc.) is already documented in the schema. The description only restates the query cap and default limit, adding no meaning beyond the structured definitions — a baseline 3 is correct.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Search for a whole shopping list in one call') plus concrete scope: up to 10 queries, each carrying the search_products filter set with 5 results by default. An agent can immediately distinguish this batch tool from the singular search_products sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly frames the batch-vs-single relationship by saying each query takes 'the search_products filters', and gives the downstream step ('Then start_checkout with the chosen variant_ids'). It does not state an explicit exclusion like 'use search_products for a single item', so it falls short of a full 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
