get_tool_usage_stats

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

No annotations are provided, so the description carries the full burden. It states the tool returns statistics (implying read-only) but does not explicitly confirm safety, permissions, or side effects. Basic transparency.

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?

Highly concise: 4 lines with front-loaded trigger hint. Every sentence adds value. No fluff 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?

Simple tool with one parameter and an output schema. Description covers purpose and parameter meaning. Could mention if results are aggregated per tool, but it's sufficient for a stats tool.

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 schema has 0% description coverage. The description explains the 'days' parameter as 'Number of days to analyze (default: 7)', adding meaning beyond the schema which only has type and default. Good compensation.

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 tool usage statistics for a specified period, using verb 'review' and resource 'tool usage analytics'. However, it does not differentiate from sibling 'browse_tool_usage' which may have similar functionality.

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 'TRIGGER' prefix provides a usage hint, but no when-not or alternative tool guidance is given. It only tells when to call, not when to avoid.

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