TDQS

C2.5/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=false, and destructiveHint=false, covering the safety profile. The description adds nothing beyond them—no pagination behavior, no rate/credit notes (which live only in schema param text), and 'returns structured image results' is redundant with the existing output schema. It does not contradict the annotations, but it contributes no behavioral value.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short but structurally wasteful: the second sentence ('Performs a Google Image search and returns structured image results') largely repeats the first without adding new information. Size is fine, but one of two sentences does not earn its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described, and the schema fully documents parameters. However, for a tool sitting among nine search-related siblings, the total absence of routing guidance leaves a meaningful gap for correct tool selection.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with each of the 6 parameters (query, page, number, country, language, image_size) fully documented including defaults, credit warnings, and enum options. The description adds no parameter meaning, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb and resource ('Search Google Images') and notes it returns image results, so the purpose is identifiable. However, it offers no differentiation from siblings like serp_google_search or serp_google_videos, relying entirely on the tool name to distinguish it. The two sentences are near-synonymous, adding redundancy rather than clarity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use image search versus the sibling search tools (web, news, videos, places), no mention of prerequisites, quotas, or credit implications beyond what the schema notes. The agent is left to infer usage entirely from the tool name.

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