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

The annotations already declare readOnlyHint=false, openWorldHint=true and idempotentHint=false; the description adds what those annotations do not: a fixed two-phase order, conditional early termination when the research finds too little signal, and a concrete per-call price of $1.84 USDC. For a non-destructive but non-idempotent, paid bundle, this discloses the main behaviour a caller needs, though what the tool returns is still unstated.

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?

Three short sentences: the workflow is front-loaded, the early-exit condition precedes the pricing note, and there is no filler. The pricing parenthetical contains information the caller needs, not padding.

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?

There is no output schema, so the description must explain the return shape. It names the two phases but says nothing about what the caller receives: the sourced facts, the debate transcript, a verdict, or some combination. Given that the tool is a paid bundle, this omission leaves the description incomplete about the result.

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?

There is one optional parameter, 'task', and the schema covers it at 100%, including a description of its own, so the parameter's meaning is already fully documented. The tool description adds nothing beyond the schema about this parameter, such as its format or how it influences the phases, so it meets only the baseline.

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 specific verbs and resources: it gathers sourced facts, then runs a multi-agent debate over them. That is a clear compound purpose rather than a restatement of the name. It does not, however, distinguish itself from the closely related siblings deliberation.multi-agent-debate or research.topic-deep-researcher, which an agent would plausibly consider.

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 descriptions of the two-phase flow and of stopping early when signal is low imply when this tool is appropriate: when the caller wants research and debate in one call. No explicit when-to-use guidance is given, and no alternative is named, so the caller does not know how this differs from calling the research or debate tools separately.

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