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

No annotations are provided, and the description is extremely minimal. It does not disclose any behavioral traits, such as what data the tool operates on, side effects, or whether it requires prior data ingestion. For a tool with no annotations, the description fails to compensate.

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 with no unnecessary words. It is appropriately front-loaded and efficient.

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, no annotations, and no output schema, the description is too minimal to provide complete context. It does not explain what data is used, how results are presented, or when the tool should be invoked, leaving significant gaps for an AI agent.

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 tool has no parameters, and the schema coverage is 100%. With zero parameters, the baseline score is 4. The description adds meaning by specifying the analytical focus (title length distribution), which goes beyond the empty schema.

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 analyzes the distribution of video title lengths. It uses a specific verb+resource combination, distinguishing it from other analysis tools that focus on different aspects. However, it does not explicitly differentiate from siblings like analyze_keywords or analyze_interaction_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?

There is no guidance on when to use this tool versus alternatives. The description provides no context about prerequisites, data requirements, or scenarios where this tool is preferred over similar tools.

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