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

Annotations already mark it read-only, idempotent, non-destructive, and open-world; the description adds that it is free, returns real deliverables/capability version/price, and has no file-creation or order side effects. That is useful behavioral context beyond the annotations, though it does not discuss rate limits or authentication.

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 text is compact and front-loaded: free search, default scope, filters, pagination, return contents, and side-effect limits arrive without filler. Each clause carries operational information.

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 an output schema and rich annotations, the remaining description needs are about scope, filters, side effects, and return contents; these are all addressed. The only notable gap is explicit routing against sibling search tools.

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%, but the description names the main filters (section, output_family, operation, formats, use_case) plus limit/offset and implies query through '完整需求'. It does not explain enum value meanings, format syntax, or query behavior beyond filtering, so it only partially compensates for the missing schema descriptions.

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 names a specific verb (检索/search) and resource (已开放的制作与工具), states the default scope (搜索全部), and lists filterable facets. It does not explicitly contrast with sibling tools such as search_templates or get_tool, so sibling differentiation is implicit rather than stated.

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?

It explains the default all-search behavior, the available filter dimensions, pagination, and clarifies that it will not create files or orders, which sets usage boundaries. It does not say when to choose search_templates or get_tool instead, so alternatives remain unaddressed.

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