get_key_activity

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

Describes the response structure (endpoint, status, duration, timestamp), auth requirement, and the ordering (most recent first). Annotations indicate readOnly, which aligns; the description adds valuable context beyond annotations.

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 concise, front-loaded sentences: function, usage, auth. No wasted words, well structured for quick comprehension.

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 simple interface (1 param, no output schema), the description is complete: covers purpose, return fields, use cases, auth, and alternatives. No 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?

Schema coverage is 100% and fully describes the 'limit' parameter with defaults and maximum. The description does not add additional meaning beyond what the schema provides, so baseline score of 3 applies.

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 returns recent per-request API activity logs for the authenticated key, and distinguishes it from the sibling tool for aggregate usage trends by name.

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?

Explicitly provides when-to-use scenarios (debugging, checking errors, spotting slow requests) and when-not-to-use (usage trends), with a direct reference to the alternative tool.

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