ncloud_datafence_approve_file_export

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

The description describes a mutation ('approve', 'files are then copied to the target bucket') while the annotations declare readOnlyHint=true. This is a direct contradiction: approving and copying files is a write operation. The description also omits any disclosure of permission requirements or reversibility.

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?

Two short sentences, front-loaded with the action and followed by the key effect. Efficient with no filler, though extremely brief for a mutating approval operation.

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 is thin: it does not state permissions, irreversibility, or the pending-state prerequisite. The contradiction with readOnlyHint makes it incomplete and potentially misleading about the operation's safety profile.

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%, and each parameter (fenceId, boxId, fileId) already carries a description pointing at the relevant list/get tool. The description adds no additional parameter meaning, so the baseline 3 applies.

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?

States a specific verb+resource ('approve a file export request') and adds the consequential effect ('files are then copied to the target bucket'). The verb 'approve' is clearly distinguishable from sibling tools like reject_file_export and cancel_file_export, though those siblings are not named explicitly.

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 when-to-use guidance, prerequisites, or alternatives are given. The description never explains when approval is appropriate versus rejection or cancellation, nor what state the export must be in (e.g., pending) before approval is valid.

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