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

The description states 'no external research or outbound actions' and 'returns a draft for human review,' yet the annotations declare openWorldHint=true and destructiveHint=true. This is a direct contradiction: the description claims a closed, non-destructive generation behavior while the annotations warn of open-world and destructive characteristics. Score 1 per the contradiction rule.

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 compact and front-loaded with the core action: create an about page from supplied content. Each sentence adds meaningful information, though 'buyer-supplied information only' partially repeats the earlier 'supplied... only' constraint. Minor redundancy, but otherwise well-structured.

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 five parameters, a nested input object, no output schema, and no parameter documentation, the description should explain how to provide the source material, what the returned draft looks like, and what payment authorization entails. It only says a draft is returned and payment requires wallet authorization, which is insufficient for reliable invocation.

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% and the description does not explain any of the five top-level parameters or the nested input fields. It alludes to buyer-supplied content and wallet authorization, but it does not connect those concepts to brief, audience, source_text, payment_signature, idempotency_key, or result_expires. For a low-coverage schema, the description should have compensated.

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 verb and resource: create a business about page. It also specifies the source scope — supplied history, mission, people, and operating principles only — which clearly distinguishes it from research-based siblings like market_report_from_sources and from similar copy tools like homepage_copy or service_page_copy.

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 clear context: use buyer-supplied information only, no external research, and expect a draft for human review. It does not explicitly name an alternative tool to use when external research is needed, but the constraints are clear enough to route an agent appropriately.

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