getAnalyticsReasons

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. The description only states the function ('retrieves statistics') with no mention of rate limits, data recency, aggregation behavior, or whether the operation is read-only. The implied read-only nature is not explicitly stated.

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?

A single sentence of 8 words that is front-loaded with the verb 'Retrieves' and directly conveys the tool's purpose. No extraneous words or repetition. Every word earns its place given the conciseness.

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?

Despite the presence of an output schema (which should define the return structure), the description is too minimal for a tool in a family of over 20 analytics tools. It lacks context on when to use this versus siblings, the scope of 'statistics' (e.g., time range constraints, aggregation levels), and any prerequisites (like needing a valid profile_id). The agent would need to infer much from the output schema and parameter patterns alone.

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 coverage is 100% with descriptions for all three parameters (profile_id, from, to). The parameter descriptions are clear, including format hints (Unix or ISO 8601) and regex constraints. The tool description adds no additional parameter context beyond what the schema already provides, meeting the baseline expectation.

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 uses a specific verb ('Retrieves') and resource ('statistics about why queries were blocked'), clearly distinguishing it from sibling analytics tools like getAnalyticsDestinations or getAnalyticsDomains. However, it could be more precise about what statistics (e.g., counts, percentages) are returned, but the output schema likely fills that gap.

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 on when to use this tool versus the many sibling analytics tools (e.g., getAnalyticsReasonsSeries, getAnalyticsStatus). The description does not explain when it is appropriate to retrieve 'why queries were blocked' versus other analytics or how results differ from similar tools.

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