ncloud_datafence_set_box_external_network_block

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

Annotations already declare idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds the polarity semantics (true=block, false=allow) but does not say whether the change applies immediately, whether it affects a running box, or what authorization is needed — so it adds modest value over the 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?

A single front-loaded sentence with zero filler; the action and its boolean argument are stated in one pass.

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 idempotent toggle with full schema coverage and safety annotations, the description is nearly sufficient. It could still note preconditions or immediate-effect behavior, but nothing essential for calling it correctly is missing.

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 all three parameters are documented in the schema, including the true/false meaning of isBlock. The description's restatement of that boolean adds nothing beyond the schema, 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 action (block/allow) on a specific resource (a Box's external network access), and the boolean polarity is spelled out. It does not explicitly contrast itself with sibling tools, but the datafence/box scoping makes the intent unambiguous.

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?

Gives no guidance on when to use this versus alternatives, no preconditions (e.g. box state, required permissions), and no note on when blocking is appropriate. The only routing hint is the boxId parameter description pointing at ncloud_datafence_list_boxes, which is schema text, not description text.

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