rba_ping_clients

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

No annotations are provided, so the description carries the full burden. The word 'Ping' implies a non-destructive, read-only operation, but the description does not explicitly confirm safety or disclose behavior on timeout or unreachable clients. It does clarify the return payload (round-trip timing and place/job details), which adds some transparency beyond the bare name.

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 one concise sentence that front-loads the primary action and outcome. Every word adds value, with no filler or redundancy.

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 is relatively simple, and the description covers the main purpose and return value. However, with no annotations or output schema, it would benefit from mentioning the 'target' parameter behavior and what happens on timeout. The description is adequate but leaves key operational details to be discovered.

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 description coverage is 0%, so the description must compensate by explaining parameters. It mentions 'connected clients' but does not explain the 'target' parameter (all, first, or a specific client index) or the 'timeoutMs' parameter. The description provides no additional meaning beyond the raw schema.

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 action ('Ping connected clients'), the resource ('connected clients'), and the result ('return round-trip timing plus basic place/job details'). The specific verb and output make it distinct from sibling tools like rba_health_check, which likely checks overall system health rather than round-trip timing.

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 (to measure latency to clients) but does not explicitly state when to use this tool versus alternatives. No exclusions or alternative tool references are provided, so the agent must infer usage from the tool's name and description.

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