ncloud_add_network_acl_inbound

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

The annotations provide destructiveHint: false, indicating the tool is non-destructive, but the description adds no behavioral context beyond 'Add'. It does not disclose whether the rule is appended immediately, if duplicates are allowed, or what the response format is (no output schema), leaving the agent with minimal insight into the tool's behavior.

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 7-word sentence that is front-loaded with the core action. It is appropriately concise but could be slightly more informative without sacrificing brevity, such as mentioning 'to an existing Network ACL'.

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 complexity of 8 parameters and no output schema, the description is too minimal. It lacks context about prerequisites (e.g., the ACL must exist), the effect of priority ordering, or what happens upon success (e.g., rule ID returned). The tool's behavior is not fully described.

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?

All 8 parameters have descriptions in the input schema (100% coverage), so the baseline is 3. The tool description does not add any additional meaning beyond the schema, such as clarifying relationships between parameters (e.g., ipBlock vs denyAllowGroupNo). It neither improves nor degrades the semantic understanding.

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 'Add an inbound rule to a Network ACL' clearly states the verb ('Add'), the specific resource ('inbound rule'), and the parent object ('Network ACL'). It distinguishes this tool from siblings like ncloud_add_network_acl_outbound and removal tools, as 'inbound' and 'add' are explicit.

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 is provided on when to use this tool versus alternatives such as outbound rules or rule removal. There is no mention of prerequisites (e.g., requiring an existing Network ACL) or when not to use it, leaving the agent without context for decision-making.

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