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

With no annotations, the description must carry the full behavioral burden. It does disclose the shape of the output (suggested answer structure, structured data type, related site content), which is genuine value since no output schema exists, but it says nothing about execution characteristics, auth needs, or whether classification is deterministic.

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 dense sentence with the classification task front-loaded and the returned artifacts trailing. Nothing is wasted, though the enumeration of four intents plus three outputs in one clause makes it slightly heavy.

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, no-annotation, no-output-schema tool, the description covers purpose and rough returns but omits the parameter contract and any routing guidance among the five siblings. An agent knows what it does but not confidently when to prefer it.

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 0% and the single required parameter 'q' has no schema description. The description partially compensates by defining the input as 'a search or question', but adds no guidance on language, length, or formatting of that string.

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 pairs a specific verb (classify/judge) with a concrete resource (a search query or question) and enumerates the four target categories, plus the artifacts returned. It is clearly distinct from retrieval-oriented siblings like search_glossary or get_howto, though it never names them explicitly.

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 statement of when to call this tool versus the siblings (explain_term, compare_concepts, get_howto, list_topics, search_glossary) and no exclusions or prerequisites. Usage is only inferable from the fact that it takes a query.

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