Redis Ping

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

No annotations are provided, so the description carries the burden. It discloses the operation (PING) and its purpose (availability check), which implies a read-only, non-destructive behavior. It doesn't detail response format or error behavior, but for a simple ping tool this is adequate.

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, concise sentence that states the tool's purpose without waste. It is appropriately sized for a simple ping 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?

For a simple availability check with an output schema present and no required params, the description is nearly complete. It could mention that it returns PONG or a similar response, but the output schema likely covers that. The simplicity of the tool lowers the bar.

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%, but the only parameter is 'params' with additionalProperties true and default null, which is a generic passthrough. The description doesn't add parameter details, but the schema is permissive and the tool likely needs no specific params. Baseline 3 is appropriate since the schema is minimal and the description doesn't need to compensate much.

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 'Проверка доступности Redis (PING)' clearly states the tool checks Redis availability via PING, a specific verb and resource. It distinguishes itself from sibling Redis tools like redis_info or redis_clients, though it doesn't explicitly name them.

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 for checking Redis availability, which is clear enough given the tool name and siblings. However, it doesn't explicitly state when to use this over other Redis tools or provide exclusions, leaving some inference to the agent.

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