futures_gfex_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 essentially no behavioral context beyond the title and a source URL – no note on data latency, coverage, pagination, or what the report contains.

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 is front-loaded in the title line, followed by the authoritative source URL and a compact param/return block. It is slightly redundant in restating the title, but no sentence 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?

For a one-parameter read-only data fetch with annotations covering the safety profile and no output schema, the description supplies the date format and points to the source, which is enough to call it correctly. Return structure detail is not strictly required here.

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%, so the description must carry the parameter meaning, and it does: it names the single parameter date, describes it as the trading day (交易日), and gives the exact format example "20240122". This is the critical semantics the schema omits.

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 specifies a concrete resource and scope: GFEX (广州期货交易所) warehouse-receipt daily report (仓单日报), which is distinct from the sibling warehouse-receipt tools for SHFE, CZCE, and DCE. It is clear and specific, but it does not explicitly name those siblings to help the agent route between exchange variants.

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 when-to-use or when-not-to-use guidance, and no mention of alternatives such as futures_shfe_warehouse_receipt or get_receipt. The only usage hint is the date format example, which is a parameter concern rather than selection guidance.

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