ncloud_set_port_plugins

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

Annotations already declare idempotentHint=true and destructiveHint=false, so the description need not repeat these. It adds the detail 'sends the entire list', indicating a full replacement. However, it does not disclose additional behaviors such as required permissions, effects on current monitoring, or rate limits, which would be useful for a mutation tool.

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 sentence of 15 words, completely front-loaded with the action. It contains no unnecessary words or repetition, making it highly efficient for an agent to parse.

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?

With no output schema, the description does not explain what the API returns (e.g., success status or updated plugin list). It also omits constraints like maximum number of plugins or behavior on empty list. For a simple replace operation, this may be sufficient, but additional details would improve completeness.

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 description adds meaning to the portList parameter by clarifying it represents the full set to replace existing plugins. This goes beyond the schema's description ('Full list of port numbers to monitor (replaces existing)') by emphasizing that it is not an incremental update. The other parameters (instanceNo, type) are adequately covered by the schema.

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 clearly states the tool replaces the full set of port monitoring plugins with the verb 'Replace' and emphasizes 'full set' and 'sends the entire list'. This distinguishes it from siblings like ncloud_add_port_plugin and ncloud_remove_port_plugin, which perform incremental changes.

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 implies use for setting an exact list of plugins, but does not explicitly state when to use this tool versus incremental alternatives (e.g., add or remove). It lacks prerequisites or exclusions, leaving the agent to infer usage context from the schema and sibling names.

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