get_traffic_snapshot

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

The description discloses that credits vary and requires an API key, offering some behavioral insight. However, since no annotations are provided, more details like rate limits, idempotency, or data freshness would be beneficial for a read operation.

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 appropriately concise with three sentences, front-loading the purpose. It avoids fluff, though it could include brief parameter details without significant bloat.

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?

Given the tool has only two parameters and an output schema, the description provides the core purpose and some behavioral context. However, it lacks explanation of the location parameter and expected output format, leaving minor gaps.

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?

The description only implicitly references the domain parameter, but completely omits the location parameter which has a default but is not explained. With 0% schema description coverage, the description should elaborate on parameters but barely does so.

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 gets current organic and paid traffic for a domain, which is a specific verb+resource. The purpose is straightforward, but it does not explicitly differentiate from sibling tools like get_historical_traffic, so a slight deduction.

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 mentions prerequisites (API key) and a tip to check balance via get_account_info, but provides no guidance on when to use this tool versus alternatives such as get_historical_traffic or get_keywords.

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