ncloud_ncs_copy_object

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

No annotations provided; description bears full responsibility. It lacks details about whether the copy is server-side, synchronous, overwrites existing objects, preserves metadata, or any error conditions.

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 sentence, no filler. Efficiently conveys the core action.

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 mutation tool with no output schema, the description should clarify what happens after copy (e.g., success indicator, error handling). It also fails to mention whether the operation is atomic or any limitations.

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 already provides descriptions for all three parameters with 100% coverage. The tool description adds no additional meaning beyond what is in the schema, meeting the baseline.

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?

Description clearly states action (copy) and resource (object within Ncloud Storage). However, it does not distinguish from sibling tool 'ncloud_copy_object', which likely performs a similar operation, leading to ambiguity.

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 vs alternatives. The description does not mention any prerequisites, restrictions, or context for using this copy operation.

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