C2.3/5.0

Behavior2/5

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

With no annotations provided, the description carries full burden but only discloses the 'aggregating across sources' behavior. It omits safety classification (read-only vs destructive), rate limits, specific source list, or return format details.

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

Conciseness4/5

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

Single sentence efficiently conveys the core value proposition without redundancy, though extreme brevity contributes to under-specification given the lack of schema documentation.

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

Completeness2/5

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

Given zero schema descriptions, no annotations, no output schema, and a complex ecosystem of sibling search tools, the description is materially incomplete—it fails to clarify selection criteria, parameter usage, or response structure.

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

Parameters1/5

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

Schema coverage is 0% (neither query nor max_results have descriptions), yet the description fails to compensate by explaining parameter semantics, valid query syntax, or the default max_results behavior.

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 identifies the tool as a search utility that aggregates across sources, distinguishing it from single-source sibling tools like search_arxiv. However, it lacks explicit contrast with the 20+ specific search alternatives to guide selection.

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?

The 'Deep Research compatible' phrase hints at a specific use case but provides no explicit when-to-use guidance or comparison against the numerous specific source search tools available as alternatives.

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