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

No annotations are provided, so the description must carry the full behavioral burden. It discloses nothing about acceptable integer range, IPv4 vs IPv6 handling, output format, or error behavior for invalid inputs.

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 one short, front-loaded sentence with no filler. However, its brevity reflects under-specification rather than optimal conciseness, as no useful detail is added.

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 simple conversion tool with one parameter, no annotations, and no output schema, the description still omits the expected input domain (e.g., 32-bit integer) and output representation, leaving an agent without enough context to invoke reliably.

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%, so the baseline is 3. The description's 'int' hints that the value should be an integer, but adds no format details beyond the schema's generic 'Value to process' description.

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 is essentially a restatement of the tool name: 'Int To IP: Convert int to ip.' It states the basic verb and resource but adds no information beyond what the name already conveys, and does not distinguish this from sibling x402-ip-to-int or clarify whether IPv4 or IPv6 is supported.

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 when-to-use guidance is provided. The description does not mention alternatives such as x402-ip-to-int, x402-validate-ip, or x402-is-ip, nor does it state conditions under which this tool should be selected.

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