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

No annotations exist, so the description carries the full behavioral burden. It does disclose meaningful process behavior (compares sources, validates information, highlights uncertainties) and a concrete runtime expectation (~60s). However, it does not state whether the operation is read-only, how results are delivered (beyond 'structured insights'), or how failures/source unavailability are handled.

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 front-loaded with the core action and each subsequent sentence adds distinct value (subtopics, validation, open questions). The runtime note is a useful trailing detail. It is slightly list-heavy, but there is no waste.

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 single-parameter tool with an output schema present, the description covers the process, the nature of outputs, and timing, which is reasonably complete. It does not cover failure modes, limitations of the research, or how the output schema maps to the described 'insights and open questions,' leaving some ambiguity for an autonomous agent.

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% — the 'topic' property has an empty description — so the description must compensate. It only repeats 'on a given topic,' adding virtually nothing about topic specificity, length, scope, or how to phrase the research query well. The nested payload structure is left to the schema alone.

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 uses a clear verb-resource pair ('Conducts iterative internet research on a given topic') and enumerates concrete outputs (key terms, subtopics, facts, studies, current developments, insights, open questions). However, it does not differentiate from research-flavored siblings such as scientificresearchagent, exploitagent, or firstprinciplesanalyst, so an agent cannot readily pick between them based on this text alone.

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 closing phrase 'to support the Main Agent’s understanding' gives only implied context for when to use it. There is no explicit when-to-use/when-not-to-use guidance, no stated exclusions, and no reference to alternatives (e.g., scientificresearchagent for domain-specific work). With several overlapping research tools, this is a real gap.

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