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

Annotations already signal read-only/destructive/open-world behavior, and the description adds meaningful context beyond them: no external research, no outbound actions, returns a reviewable draft, costs 0.25 USD, and requires explicit wallet authorization. It does not explain the destructiveHint, but there is no direct contradiction with the description.

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 sentences, no filler. The core output is front-loaded, followed by constraints, deliverable status, and payment requirements. Every sentence earns its place.

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 tool with 5 parameters, nested input, payment/signature fields, and no output schema, the description is not complete enough to confidently construct a full invocation. It never explains the crypto-signature fields, result expiration, or idempotency semantics, which are nontrivial for an agent to infer on its own.

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 needed to compensate. It only broadly refers to 'buyer-supplied information' and mentions wallet authorization, which hints at payment_signature but does not explain brief, audience, source_text, result_expires, idempotency_key, result_signature, or payment_signature by name or meaning.

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 a specific verb and resource: 'Create an episode premise, segment rundown, host questions, and closing takeaways.' This clearly identifies the tool as a podcast episode outline generator and differentiates it from the many sibling outline tools (webinar, training, sales deck, etc.).

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 provides useful context: it uses buyer-supplied information only, performs no external research or outbound actions, and returns a draft for human review. However, it never explicitly names alternatives or states when-not-to-use conditions, leaving the routing decision mostly implicit.

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