EU declaration basis

check_eu_declaration_basis

Read-onlyIdempotent

Use when a buyer, customs or distributor requests an EU Declaration of Conformity. Returns applicable legislation, standards, evidence gaps and fields needing confirmation immediately. Does not issue or sign a declaration.

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
`age_group`	No	Intended user age. Decides whether toy safety rules apply and which small-parts and warning duties follow.
`has_radio`	No	Whether the product transmits: Bluetooth, Wi-Fi, NFC, or any other radio. Decides the RED conformity route in the EU and FCC authorisation in the US.
`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
`eu_destination`	No	Destination member state, where it changes the answer. Language and producer-registration duties differ across the EU.
`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.
`is_childrens_product`	No	Whether the product is marketed as a children's product; keep unknown when not established.
`food_contact_material`	No	The material that touches food. Migration limits and test methods differ by material.
`includes_mains_charger`	No	Whether a mains plug, wall charger or power adapter ships in the box. A supplied charger is separately in scope.
`is_electrically_operated`	No	Whether the toy is electrically operated, including mains-powered or battery-powered operation.
`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.

TDQS

A4.2/5.0

Behavior4/5

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

Annotations already cover read-only and non-destructive semantics. The description adds useful behavioral detail: it returns results immediately, reports gaps and confirmation fields, and explicitly does not issue or sign the declaration. There is no contradiction with the annotations.

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?

Two sentences with no filler: trigger first, output second, boundary last. Every sentence carries selection-relevant information.

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?

Given the rich input schema, output schema, and annotations, the description is nearly complete for correct selection and invocation. The only gap is that it does not explicitly point the agent to sibling tools when the request is not about an EU DoC, leaving some routing to inference.

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 structured schema already documents all 21 parameters. The description does not add parameter-level detail, but also does not need to; it stays at the level of overall purpose and outputs.

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 starts with a specific trigger ('buyer, customs or distributor requests an EU Declaration of Conformity') and names its exact outputs ('applicable legislation, standards, evidence gaps and fields needing confirmation'). The closing line 'Does not issue or sign a declaration' clearly separates it from a document-generating tool. This distinguishes it from sibling tools like check_us_import_certification or check_bat_ery_transport_documents by its EU DoC focus.

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?

'Use when...' is an explicit condition for selecting this tool over siblings. The 'Does not issue or sign' line adds a when-not boundary, but the description does not name specific alternative tools or state when to prefer them.

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