futures_shfe_warehouse_receipt

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds the source URL and the return type (dict), which is modest extra context, but says nothing about the report's structure, timeliness, or whether a missing trading day returns empty.

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?

The purpose line is front-loaded and brief, but the raw URL and the bare Sphinx-style docstring (:param:/:type:/:return:/:rtype:) are noisy padding that add little beyond the intended field documentation. It is short but not cleanly structured for an agent.

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?

With no output schema, the description should characterize the return value, but ':return: 指定日期的仓单日报数据 / rtype dict' is vague and gives no field structure. Given annotations cover safety and the parameter is documented, this is minimally viable but leaves the response shape opaque.

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% (the only field is a bare string with a default), so the description carries the burden. It does supply meaningful semantics: date is the 交易日 (trading day) in 'YYYYMMDD' form with the example '20260924', which the schema alone does not convey.

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?

The description clearly names the resource: the SHFE (上海期货交易所) designated delivery warehouse futures warehouse receipt daily report, which is a concrete verb+resource. However, it does not differentiate itself from close siblings like futures_warehouse_receipt_czce, futures_warehouse_receipt_dce, or futures_gfex_warehouse_receipt beyond the exchange abbreviation already in the name.

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?

There is no guidance on when to use this tool versus the many sibling warehouse-receipt and inventory tools (czce/dce/gfex variants, get_receipt, futures_inventory_em). No conditions, exclusions, or alternatives are stated — the agent must infer usage entirely from the exchange in the name.

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