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

Annotations already indicate readOnly, openWorld, and idempotent behaviors. The description adds transparency about the snapshot nature and plan-gated degradation to an error envelope, which goes beyond annotations. No contradictions.

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 two sentences, front-loading the core purpose and then adding necessary caveats. It is concise but could be slightly more streamlined. Still, it earns its length.

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's simplicity (2 optional params, no output schema), the description adequately explains the return type (snapshot with specific metrics) and the error condition. It could mention the output format more explicitly, but it's sufficient for an agent.

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?

Input schema has 100% description coverage for both parameters (refresh and instance). The tool description does not add any additional meaning beyond what the schema already provides, so baseline score of 3 is appropriate.

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?

Description clearly states it fetches a current account-overview snapshot for Zendesk Talk, listing specific metrics like average wait/handle time, calls in queue, agents online. It distinguishes itself from historical analytics by directing users to Explore. The verb 'Fetch' and resource 'account-overview snapshot' are specific and unique among sibling tools, which lack any talk-specific tool.

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?

Description mentions plan-gating and error behavior, indicating when the tool may not work. It also suggests using Explore for historical analysis, providing context. However, it lacks explicit 'when-to-use' vs alternatives, but since no sibling talk tool exists, the guidance is sufficient.

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