getAnalyticsReport

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

Annotations declare readOnlyHint=true, so the description does not need to restate that. The description adds what data the report contains, which is useful. However, it does not disclose any limitations, rate limits, or data freshness, which are not critical for a read-only report 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?

The description is a single, focused sentence that directly states the content of the report. No unnecessary words or repetition.

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?

The tool is simple with one optional parameter, but there is no output schema. The description gives a high-level idea of return data (top tools, hook events, automation tasks) but lacks detail on structure (e.g., is it a list, object, any nested fields). Given the simplicity, it is marginally adequate but could be improved.

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%, so baseline is 3. The description does not mention the windowHours parameter or add any meaning beyond the schema. The schema itself provides a clear description and constraints.

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 report contents: 'top tools by call count, hook events, recent automation tasks.' It implies the tool retrieves a session analytics report. However, it does not explicitly use a verb like 'retrieves' or 'gets', relying on the tool name for action.

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?

There is no guidance on when to use this tool versus alternatives like getSessionUsage or getPerformanceReport. No context about prerequisites or when not to use it is provided.

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