get_my_api_usage

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

No annotations provided. The description discloses it is a read operation returning aggregated usage data. It does not discuss rate limits or quotas, but the behavior is adequately transparent for a simple query.

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 a single sentence, concise and front-loaded. No wasted words.

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 no parameters and no output schema, the description is sufficiently complete. It states the output is per-5-minute aggregation. Could mention if data is limited to a certain time range, but not critical.

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?

No parameters exist, so schema coverage is 100%. The description adds no parameter info, but none is needed. Baseline for 0 parameters is 4.

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 retrieves API usage statistics aggregated per 5 minutes. The verb 'Get' and resource 'your API usage statistics' are specific. It distinguishes from siblings which fetch sports data.

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 implies usage for checking API consumption but does not explicitly state when to use vs alternatives or provide exclusion criteria. Siblings are all different endpoints, so it's somewhat clear but could be better.

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