ncloud_get_mysql_recovery_time

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

Annotations already declare readOnlyHint=true, so the description does not need to restate read-only. It adds no additional behavioral context (e.g., that the time range depends on backup status), but does not contradict annotations.

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?

Single concise sentence of 20 words that effectively communicates the tool's purpose without repetition or unnecessary details.

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 read-only tool with 2 parameters, the description adequately explains what it returns and the resource type. However, it does not mention that the result is tied to a specific instance (though implied by the parameter).

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 descriptions for both parameters. The description adds no further meaning beyond the schema; mentioning the output format is not parameter-specific.

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 'Get the available recovery time range' for a Cloud DB for MySQL instance, using a specific verb and resource. Among sibling tools like ncloud_get_mysql_instance_detail and ncloud_list_mysql_instances, this tool is uniquely identified as retrieving recovery time range.

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 on when to use this tool versus alternatives like other MySQL tools. Lacks prerequisites, exclusions, or context for when to choose this over similar operations.

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