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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the description needn't cover safety. It adds useful context about data sources (8 platforms, listed names) and the report's coverage, but omits behavioral details like update frequency, rate limits, or response shape beyond the rtype.

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 description is bloated and repetitive: the opening paragraph and the '名词释义' section duplicate the same content. It includes a lengthy trading strategy and a URL that, while contextually relevant, are not needed to invoke the tool correctly. It is not front-loaded for tool selection.

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?

Given no output schema and two undocumented parameters, the description provides substantial content about the report's scope and data sources. However, it lacks essential parameter formats and the parameter notes contain an error, leaving gaps for an agent to call it correctly.

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 compensate. It lists start_date and end_date as 'specific trading day' but gives no format (e.g., YYYYMMDD) and contains a likely error ('same as end_date' for end_date). This is insufficient for correct parameter usage.

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 identifies the tool as a Jin10 forex speculative sentiment report, detailing the exact currency pairs and gold instrument covered. It distinguishes itself from generic forex quote tools by focusing on long/short position ratios from multiple platforms, but it does not explicitly name sibling alternatives or state a verb like 'retrieve'.

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?

The description provides a contrarian trading strategy for interpreting the data (e.g., when short positions exceed 60%, go long), but this is not guidance on when to call this tool versus other forex or macro tools. There is no mention of prerequisites or exclusions.

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