ncloud_set_port_plugins

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

The description goes beyond annotations by explaining that this is a full replacement operation, which implies existing plugins not in the new list will be removed. This is important behavioral context that the annotations (idempotentHint, destructiveHint) do not fully convey. The description is transparent about the 'replace' semantic.

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, well-structured sentence that front-loads the action and key detail. It contains no filler and is appropriately sized for the tool's complexity.

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 simple 3-parameter schema, complete schema coverage, and no output schema, the description adequately explains the tool's purpose and behavior. It covers the essential 'full replace' semantic, which is the crucial context an agent needs. No major gaps identified.

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?

The input schema already provides 100% coverage with descriptions for all parameters, including the key note that portList 'replaces existing'. The description adds little beyond that, so the baseline score of 3 is appropriate.

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 uses a specific verb 'Replace' and clearly identifies the resource ('port monitoring plugins') and scope ('for a server instance'). It also clarifies the key behavior ('sends the entire list'), which distinguishes it from sibling tools like add/remove/get port plugins.

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?

The description implicitly communicates when to use this tool: when you need to replace the entire set of port monitoring plugins rather than add or remove individual ones. It does not explicitly name alternatives, but the context of sibling tools (add/remove) makes the usage clear.

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