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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, so the description does not need to restate safety cues. It adds valuable context by mentioning the 'live gateway' and detailing the kind of information returned (costs, outcomes), which goes beyond structured fields.

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 extremely concise, consisting of two short sentences that immediately convey the verb, resource, and scope. It contains no filler or redundant information and is easy to parse.

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, existing annotations, and the presence of an output schema, the description provides sufficient context for an agent to understand what the tool does. It could mention the workspace filtering capability or time bounds, but the schema covers parameters and the output schema handles return details, so the description is largely complete.

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 fully describes both parameters (limit and workspace) with their own descriptions, so the schema carries the semantic load. The tool description does not add any additional parameter-specific guidance, matching the baseline expected for high 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 uses a specific verb 'Retrieve' and a clear resource 'A2A interaction logs from the live gateway', making the tool's primary function obvious. It further lists what the logs show (which agents called which, actions, costs, outcomes) which adds specificity and helps distinguish it from sibling tools like thinkneo_a2a_audit.

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 states what the tool does but provides no guidance on when to use it versus alternatives such as thinkneo_a2a_audit or thinkneo_a2a_flow. There is no mention of preferred contexts, exclusions, or related tools, leaving the agent without direction for tool selection.

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