Create Virtual_circuit_termination

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

Annotations already indicate this is a write operation (readOnlyHint=false) and not destructive (destructiveHint=false). The description adds that it creates a new row and specifies the return format, but no additional behavioral traits like permissions, side effects, or error handling. It adds some value but not much beyond 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?

The description is extremely concise: two sentences plus a brief returns note. No redundant information; every sentence earns its place. The main action is front-loaded.

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?

Without an output schema, the description mentions the return format (Markdown or JSON), which is helpful. However, it does not describe the structure of the created object, permissions, or potential errors. Adequate but could be more comprehensive.

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 coverage is high (86%), with descriptions for most parameters. The description does not provide extra parameter-specific information beyond the schema, so it meets the baseline of 3.

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?

Description clearly states 'Create a new virtual_circuit_termination in NetBox', providing a specific verb and resource. It distinguishes this tool from sibling tools like update and delete for the same resource, as well as create tools for other resources.

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 includes a dry-run caution ('Ask before calling if the user wanted a dry-run'), indicating a guideline for use. However, it does not provide explicit when-to-use or when-not-to-use guidance, nor compares to alternatives like update or list tools.

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