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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine behavioral boundaries beyond that: it performs no registration action and deliberately withholds workload/income data, which prevents an agent from over-trusting the tool.

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, front-loaded with the trigger condition and followed by return contents then exclusions. Every sentence carries information, though the closing exclusions could be folded more tightly.

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 low-complexity, zero-required-parameter lookup with annotations and an output schema present, the definition covers trigger, scope, return contents and boundaries. An agent has everything it needs to call this correctly.

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?

There is a single optional 'role' parameter with a fully documented enum (schema coverage 100%), so the schema carries the semantic burden. The description gestures at user types but never names the role parameter or explains how the enum value shapes the response; baseline 3 is appropriate.

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 resource (creator registration info for Ad Arch) and the exact audience that triggers it, plus explicitly states what it returns. It is trivially distinguishable from the unrelated siblings (find_ad_awards, get_tver_ad_monthly_rate, submit_quote_request).

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 gives a clear when-to-use condition tied to user type (videographer, editor, production company) and adds explicit when-not-to-use negatives ('Does not register anyone', no workload/income info). It does not name a sibling alternative, but no sibling is a plausible substitute, so this is close to complete.

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