search_images

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

No annotations are provided, so the description carries the full burden, and it discloses almost nothing. "Search" weakly implies a read-only lookup, but there is no statement about scope (local registry vs. remote), pagination, or rate limits.

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 definition is two words long, which is brevity by omission rather than by efficient structure. Nothing is front-loaded because nothing meaningful is said at all.

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 parameters, no annotations, and no output schema, the description is the only source of information, and it explains nothing about how a parameterless "search" is scoped or what it returns. An agent cannot reliably invoke this tool from the definition alone.

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?

The tool declares zero parameters, so there are no parameter semantics to explain; per the rubric this yields a baseline of 4. There is nothing in the schema for the description to add meaning to or to contradict.

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?

"Search images" restates the tool name almost verbatim, giving no verb+resource specificity beyond what the name already conveys. It does not distinguish this tool from the many image-related siblings (list_images, list_all_images, pull_image, remove_image) or clarify what corpus is being searched.

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 when-to-use guidance, no mention of alternatives, and no condition under which an agent should prefer this over list_images or list_all_images. The agent is left to infer everything from the name.

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