Behavior2/5

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

The description only includes the HTTP method and endpoint, which adds minimal value beyond the annotations. Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is known, but no additional behavioral details (e.g., pagination, filtering behavior) are provided.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short and to the point, but it is under-specified for the complexity of the tool. While concise, it should include additional context such as typical use cases or sorting behavior.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description lacks information about the return format, pagination behavior, or how to interpret the response. Although the input schema is complete, the description does not cover output details, which is important for a list tool with 12 parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the parameters are fully described in the input schema. The description does not add any extra meaning or clarify parameter usage beyond what the schema already provides, meeting the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the verb 'List' and the resource 'pre release versions', making the action clear. However, it does not distinguish itself from sibling tools like 'pre_release_versions__get' or 'apps__pre_release_versions__list', which also list pre-release versions but with different scopes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 required context, such as filtering by app, or that other list methods exist for specific apps.

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