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

Annotations already declare openWorldHint=true, non-read-only, non-idempotent, non-destructive, so the mutating external-request nature is covered. The description usefully adds that quotes are observations rather than guaranteed prices or availability, which is real value. However, it says nothing about the confirm_submission flag, expected turnaround, or that the request is dispatched to a human/agent workflow.

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

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

Two short sentences, front-loaded with the core action and followed by a useful caveat; no filler. It is arguably too terse for the parameter surface it carries, but nothing is wasted.

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

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

An output schema exists, so return values need no explanation, but the description leaves the request lifecycle opaque: no mention of confirmation, dispatch, or what contact/subject/location control. For a six-parameter, open-world request tool this is under-specified.

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

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

Schema description coverage is 0% across six parameters, and the description explains none of them. The meaning of task, contact, subject, language, and especially confirm_submission (a boolean defaulting to false) is left entirely to inference, which is a significant gap for a 6-param tool.

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

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

States a concrete verb and resource: requesting collection of offline seller quotations, scoped geographically to Shenzhen. It distinguishes itself from capabilities like verify_stock_on_site or request_on_site_check by emphasizing quotations rather than verification, though it doesn't name those siblings explicitly.

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

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

No guidance on when to prefer this over request_huaqiangbei_search, request_on_site_check, or verify_seller_claim, all of which overlap in the sourcing space. The intended usage is only implied by the word 'quotations'.

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