ncloud_accept_reject_vpc_peering

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

The description indicates a mutating operation but lacks details on effects (e.g., the request is no longer pending), required permissions, or potential side effects. With no annotations, the description provides minimal behavioral context.

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, concise sentence with no unnecessary words. It clearly communicates the tool's purpose without redundancy.

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 2-param tool with no output schema, the description is minimal. It lacks context about prerequisites (pending request), response format, or what happens after the action. While not severely incomplete, it could provide more useful information.

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%: both params (isAccept, vpcPeeringInstanceNo) have clear descriptions. The tool description adds no additional parameter meaning, so baseline 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 'Accept or reject a pending VPC Peering request' clearly states the action (accept/reject) and the resource (VPC Peering). It is specific and distinguishes from sibling tools like list, create, delete, etc.

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 (e.g., create, delete). There is no mention of prerequisites like the request must be pending, nor any when-not-to-use instructions.

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