ncloud_create_cache_manual_backup

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

Annotations only provide destructiveHint=false, but the description adds no behavioral details beyond the basic action. It does not disclose what happens during backup creation (e.g., duration, cost implications, impact on performance), nor any side effects or limits.

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 a single, concise sentence with no extraneous words. It efficiently conveys the purpose, though it could be slightly expanded without losing conciseness.

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 creates a manual backup and has no output schema, the description should explain the backup lifecycle (e.g., how to verify or restore) or any constraints. It fails to mention that the backup name must be unique or that the instance must exist. Context is minimal.

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 100%, so the baseline is 3. The description adds no extra meaning beyond the schema's parameter names and brief descriptions. It does not clarify valid backup name patterns or how to obtain the instance number.

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 action 'Create a manual backup' and the target resource 'Cloud DB for Cache instance'. It uses a specific verb and resource, distinguishing it from sibling tools like list, delete, flush, or export backups.

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. It does not mention prerequisites (e.g., instance must exist) or when manual backups are preferred over automatic ones. No exclusion or context for usage.

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