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

With no annotations, the description carries the full burden. It discloses that the tool sends queries to Higress and integrates multiple engines, but does not mention behavior traits such as authentication needs, rate limits, failure modes, or how results are processed. This is minimal disclosure for a tool that performs external queries.

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 concise with a lead sentence and a bullet list with emojis. It presents information efficiently, though the phrase 'provide up-to-date information' is slightly redundant with 'real-time search results'. Overall well-structured.

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 one parameter and an output schema, the description explains sources and purpose adequately. However, it lacks details on how results are returned (e.g., format, ranking) and whether search scope can be controlled. It is minimally complete for a search tool.

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 coverage is 100%, providing baseline 3. The description adds value by explaining that the query is used to search multiple sources (Internet, Academic, Internal) and gives examples. This adds context beyond the bare schema description, justifying a 4.

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 states that the tool enhances AI responses with real-time search results from search engines via Higress. It identifies the verb 'enhance' and the resource 'search results', making the purpose clear. However, the primary functional verb could be more direct like 'search'.

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 implies usage when up-to-date information is needed (e.g., 'real-time search results'). It lists categories of search sources, but does not provide explicit when-to-use, when-not-to-use, or alternatives. Since there are no sibling tools, the lack of exclusions is less critical.

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