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

The annotations mark the tool as openWorldHint=true, yet the description asserts 'Uses buyer-supplied information only; no external research or outbound actions.' This directly conflicts with the annotation's implication that the tool may access or affect the outside world. The payment disclosure is helpful, but the contradiction requires a score of 1.

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 five short, purposeful sentences that front-load the core outcome, then add constraints, return behavior, price, and wallet authorization. Each sentence carries distinct information with no filler.

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 output schema and no parameter descriptions, the description must carry more weight. It covers the deliverable and payment model but omits return format, how optional parameters affect behavior, and how signatures/expiry fit into invocation. This is not enough for an agent to confidently call a five-parameter paid tool.

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 percent, and the description never explains the required `brief`/`source_text`, optional `audience`, or the signature/expiry/idempotency parameters. The high-level statement 'buyer-supplied information only' gives some context but does not compensate for the absent parameter documentation.

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 names a specific deliverable and verb ('Create a timed, outcome-oriented agenda') and enumerates concrete components: preparation, decisions, participants, and follow-up ownership. This makes the tool's purpose clear and distinguishes it from generic copy or brief-generation siblings.

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?

It provides clear context: the tool uses buyer-supplied information only, returns a draft for human review, and explicitly rules out external research or outbound actions. It does not name a sibling alternative such as meeting_brief or spell out comprehensive when-not-to-use cases, so it falls just short of a 5.

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