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

Annotation Contradiction: annotations mark openWorldHint=true, but the description states the tool uses buyer-supplied information only and performs no external research or outbound actions. This conflict makes expected behavior ambiguous for an agent, and the description does not reconcile its stated constraints with the destructiveHint/idempotentHint annotations.

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 short sentences convey purpose, boundary, deliverable, and payment in a front-loaded order with no filler. Every sentence contributes information needed to decide or call the tool.

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 paid content-generation tool with no output schema, the description gives the core deliverable, boundary, and payment requirement, but is incomplete for safe invocation: it lacks the output draft's shape, practical payment-signature handling, and any note on result_expires/result_signature. The conflicting annotation also undermines completeness.

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%, so the description bears the burden of explaining parameters. It only hints at buyer-supplied input and payment/wallet authorization; it does not explain audience, source_text, idempotency_key, result_expires, or result_signature, leaving the agent to infer their roles from names and patterns.

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?

Description opens with a specific verb and artifact: 'Create a research-led white paper structure' with concrete components (arguments, evidence requirements, executive synopsis). This clearly distinguishes it from the many sibling outline tools because the resource is explicitly a white paper and the scope is research-led structure, not a generic markdown heading outline.

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 gives a clear usage boundary: 'Uses buyer-supplied information only; no external research or outbound actions' and notes the output is 'a draft for human review.' It does not name alternative sibling tools or explicitly state a when-to-use condition, so it stops 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.
