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

With no annotations, the description carries full burden for behavioral traits. It only mentions 'comprehensive analysis' without indicating read-only/mutation, permission needs, output format, or potential data volume. The agent cannot assess side effects or constraints.

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 concise sentence that front-loads the purpose. While it is brief, it contains no wasted words. However, it could benefit from additional structure (e.g., separating output or usage notes).

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 that it is an analysis tool, its outputs are not defined, and there is no output schema. The description fails to explain what the analysis returns (e.g., aggregated metrics, trends, or visualizations). This leaves the agent lacking critical information for proper invocation.

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 descriptions already cover both parameters (startDate and endDate) with format and required indicators. The tool description adds no extra meaning beyond the schema, so the baseline score of 3 is appropriate.

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 it performs 'comprehensive analysis of training trends, volume, and patterns over a date range.' It uses a specific verb ('analyze') and resource ('training trends, volume, and patterns'), effectively distinguishing it from sibling tools that retrieve specific data points or perform simple operations.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, scenarios where it is preferred, or any limitations. This forces the agent to infer context from the name and siblings.

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