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

The description adds context beyond annotations by stating no external research, returning a draft for human review, and requiring payment with wallet authorization. However, it contradicts the openWorldHint annotation which suggests external data access, and the payment detail only partially explains destructiveHint true.

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?

Four sentences with no fluff; the main action is front-loaded, and pricing/payment are included efficiently. Could be slightly more structured but is appropriately concise.

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?

The tool has 5 parameters, a nested object, and no output schema, yet the description lacks parameter explanations and output format details. It only vaguely says 'returns a draft for human review' without specifying the structure. This is insufficient for a paid, side-effectful 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 coverage is 0% and the description doesn't explain the parameters. It mentions 'buyer-supplied information' but doesn't map that to the input object's fields (brief, source_text, audience). It also doesn't clarify the purpose of result_expires, idempotency_key, or payment_signature.

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 clearly states the tool organizes supplied stakeholders by role, needs, dependencies, and engagement actions, and explicitly notes it uses only buyer-supplied information. This is specific and differentiates it from sibling tools like buyer_persona or competitor_comparison.

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 description implies when to use it (when you have stakeholder info to organize) and mentions it doesn't do external research, but it doesn't explicitly contrast with alternatives or state when not to use it. No sibling names are referenced, so an agent must infer suitability.

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