get_talk_stats

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is known. The description adds no behavioral details—no mention of authentication, rate limits, data freshness, or that it returns aggregated data. Since annotations cover the read-only aspect, the description should add something like 'Returns aggregated call metrics' but does not.

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, efficient sentence with no filler. It is appropriately front-loaded with the core purpose, though it lacks additional structure (e.g., bullet points) that could be useful for a multi-parameter tool.

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?

The tool has no output schema and only a bare description. It fails to explain what the statistics contain (e.g., call volumes, agent statuses), what the return format might be, or how the report parameter influences output. For a read-only tool with optional filters, this is incomplete—an agent cannot predict what data it will receive.

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 each parameter having a description and the report parameter having an enum. The tool description does not add any parameter details beyond what the schema provides, so the baseline of 3 applies.

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 states a clear verb-resource pair ('Get Zendesk Talk statistics') and distinguishes it from siblings, as there is no other Talk-related tool. It is specific enough that an agent knows it retrieves statistics, though the exact scope (call/queue metrics) is left to the schema.

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 is given on when to use this tool versus alternatives. There are no sibling Talk tools, so the absence is not critical, but the description does not provide context like 'Use this to retrieve call performance metrics' or mention any preconditions.

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