get_top_app_versions

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states the output concept. It does not explain output structure, default period handling, or that this is a read-only query, leaving the agent without key behavioral context.

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 without redundancy, making it concise. However, its brevity contributes to under-specification, omitting important details about output and behavior, so it is not maximally effective.

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 11 parameters, no annotations, and no output schema, the description is incomplete. It does not explain the return format (e.g., a list of app versions with session counts) or any behavioral defaults beyond what the schema already documents.

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 input schema provides thorough descriptions for all 11 parameters, covering defaults and filter semantics. The description adds no parameter-specific meaning, so it meets the baseline for full schema coverage.

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's function: retrieving top app versions ranked by unique sessions for a given period. It distinguishes from sibling tools like get_top_os_versions by specifying 'app versions' and from get_top_events by the metric 'unique sessions'.

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 when the agent needs top app versions, but it does not explicitly mention when to prefer this over sibling tools such as get_top_os_versions or get_metrics. No exclusions or alternative tool suggestions are provided.

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