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. It usefully discloses that results are not content-moderated, which is a meaningful safety trait, but it does not state whether the operation is read-only, what permissions or network access are required, or any rate limits. This is a partial but not comprehensive behavioral disclosure.

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 two short sentences, front-loads the core purpose, and adds the moderation caveat without waste. Every sentence earns its place given the limited information provided.

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?

The tool has four required parameters with no schema descriptions and no annotations, yet the description explains only the query and a moderation caveat. An output schema exists, so return values need not be explained, but the input semantics and usage context remain largely incomplete for a four-parameter 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 description coverage is 0%, so the description must compensate for undocumented parameters. It only implies the meaning of 'query' and says nothing about 'count', 'gl', or 'rank', leaving three of four required parameters semantically opaque. The schema provides types only, so this is a significant gap.

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 gives a clear verb and resource: searching the web for images matching a query. There are no sibling tools to distinguish from, so the only gap is that it does not explicitly contrast with other search types. The purpose is nonetheless immediately understandable.

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 says what the tool does but provides no when-to-use guidance, no exclusions, and no alternatives. An agent can infer that it is for image search, but there is no explicit routing information or conditions under which this tool is appropriate.

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