Forwarder will not take the battery product

check_battery_transport_documents

Read-onlyIdempotent

Use when a forwarder or carrier queries or refuses a battery shipment. Returns applicable UN 38.3 test-summary requirements, shipping marks and transport evidence gaps for the cell/pack. Answers immediately from declared facts; does not inspect documents.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`case_id`	No	The case this call continues, from an earlier result. Omit to start a new product case.
`markets`	No	Optional destination-market hints. Omit when product_description names the destination.
`category`	No	Optional structured category hint. Canonical IDs and common English/Chinese labels are accepted. Omit when product_description contains enough information for extraction.
`language`	No	Language for seller-facing text. Questions and messages come back in it; en or zh.	zh
`has_battery`	No	Whether the product contains or ships with any battery, including a coin cell in a remote.
`battery_type`	No	Cell chemistry. Decides whether UN 38.3 transport testing and battery-passport duties apply. Use unknown rather than guessing.
`product_name`	No	Human-readable product or SKU name
`evidence_held`	No	Evidence IDs the seller already holds, from a previous result's evidence_checklist. Marks each item held rather than unknown; it does not verify the document.
`sales_channel`	No	Where the product is sold. Marketplaces impose their own evidence requests on top of the legal requirements.
`verified_only`	No	Exclude decision rules not checked against primary sources
`supply_chain_role`	No	The seller's role in the chain. Decides which duties are theirs rather than the manufacturer's or importer's.
`applicable_modules`	No	Optional additional modules that should be assessed together with the primary category, for example toys plus battery-electronics.
`product_description`	No	Preferred first input: describe the product, destination market, sales channel and any known supplier documents in plain language. The tool extracts a preliminary profile and fills the internal checklist. Required when category/markets are not already supplied.
`includes_mains_charger`	No	Whether a mains plug, wall charger or power adapter ships in the box. A supplied charger is separately in scope.
`evidence_inventory_complete`	No	True only when evidence_notes/evidence_text and evidence_held together form a complete inventory. Otherwise unprovided applicable evidence remains unknown, not missing.
`battery_compartment_security`	No	How the battery compartment is secured. Button and coin cells carry stricter duties because ingestion is the hazard.

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds valuable behavioral context: it 'answers immediately from declared facts' (no external lookups) and 'does not inspect documents' (no document parsing/verification). This goes beyond the annotations and helps set expectations about the tool's limits.

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 sentences, each earning its place: trigger condition, output scope, and behavioral boundary. The most important information (when to use) is front-loaded, and the 'does not inspect documents' caveat is placed at the end where it serves as a clarifying boundary rather than a distraction.

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?

The tool has 16 parameters, an output schema, and rich annotations. The description covers the trigger scenario, the output scope, and the key limitation (no document inspection). It doesn't mention that it returns evidence gaps, but the output schema would carry that. The only minor gap is not explaining how the tool relates to the broader evidence_checklist flow, but the schema's evidence_held parameter description partially covers that.

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%, so the schema already documents all 16 parameters. The description doesn't add parameter-level detail beyond what the schema provides, but it does clarify the overall input philosophy: product_description is the 'preferred first input' and the tool 'extracts a preliminary profile.' This is useful context but not parameter-specific semantics, so a baseline 3 is appropriate.

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?

The description opens with a specific trigger scenario ('forwarder or carrier queries or refuses a battery shipment') and names the exact resource (UN 38.3 test-summary requirements, shipping marks, transport evidence gaps). It clearly distinguishes this tool from siblings like check_amazon_compliance_request or check_us_import_certification by focusing on transport/forwarder refusal.

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

Usage Guidelines5/5

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

The first sentence explicitly states when to use it: when a forwarder or carrier queries or refuses a battery shipment. It also states what it does not do ('does not inspect documents'), which helps an agent avoid using it for document verification. The sibling list reinforces the differentiation, and the description's explicit trigger condition is sufficient.

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