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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses almost nothing beyond 'fuzzy search'. Ranking behavior, result count defaults, and whether results are paginated or truncated at the limit are all unstated.

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?

A single well-formed sentence with the action and scope front-loaded; nothing redundant. It is efficient, though its brevity is partly under-specification rather than true density.

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 annotations, no output schema, and 0% schema coverage on two params, the description does far too little. A search tool needs at least query semantics, result-shape hints, and distinction from the other lookup 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% on 2 parameters. The word 模糊 hints that q accepts imprecise input, but the limit parameter (1-20 cap) is completely unexplained in both schema and description, leaving the caller to guess its meaning and default.

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 specific verb (模糊搜尋/fuzzy search) and enumerates the resource scope: AI terms, concept comparisons, and practical tutorials. An agent can grasp the topic, but the description does not distinguish this tool from siblings like explain_term, compare_concepts, or get_howto, which cover the same content types.

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 use this versus the sibling lookup tools (explain_term, compare_concepts, get_howto, list_topics). The word 模糊 ('fuzzy') implies an imprecise-query use case but this is never stated as a selection criterion.

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