get_hpo_term_stats

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

No annotations are provided, so the description must disclose behavioral traits. It only states the purpose and does not mention that the tool is read-only, any required authentication, rate limits, or side effects. This leaves the agent uninformed about critical behavior.

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, well-structured sentence (14 words) that conveys the essential purpose and key outputs ('hierarchy counts and properties'). No unnecessary words.

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?

For a tool with one parameter and no output schema, the description adequately hints at the output components (hierarchy counts and properties). It could be slightly improved by mentioning the output format (e.g., object or array), but it is reasonably complete.

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 description coverage is 100% for the single parameter 'id', which already explains the format. The description does not add any new information about the parameter beyond what the schema provides, so it meets the baseline of 3.

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?

Clearly states the tool returns comprehensive statistics and analysis for an HPO term, including hierarchy counts and properties. This distinguishes it from sibling tools like 'get_hpo_term' (basic info) and 'get_hpo_children' (specific relation).

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 description implies usage for obtaining comprehensive statistics but does not explicitly specify when to use this tool versus alternatives like 'compare_hpo_terms' or 'search_hpo_terms'. No guidance on prerequisites or conditions.

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