Get IP Address

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

Annotations already declare readOnly/idempotent/non-destructive behavior, so the description's 'Operation class: Read' adds little. However, it adds value by disclosing that ids are not guessable and that Hudu returns 404 identically for missing records and unrouted paths, which is useful error-handling 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 short, front-loaded with the primary action, and every sentence serves a purpose. The final 'Operation class: Read' is slightly redundant with annotations but not wasteful.

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 get-by-id tool with no output schema, the description is complete: it defines what an ip_address record contains, explains how to find the ID, and warns about the 404 behavior. No critical operational detail is missing.

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 100%, so baseline is 3. The description adds semantic context for the id parameter ('ids are not guessable') and clarifies the record concept, going beyond the schema's property descriptions.

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 opens with a specific verb and resource: 'Fetch one ip address by its numeric id.' It clearly identifies the tool's scope (single record by ID) and distinguishes it from sibling tools like hudu_list_ip_addresses, which lists records.

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 provides explicit guidance: 'Use hudu_list_ip_addresses first if you only know a name — ids are not guessable.' It also explains the 404 ambiguity, giving a concrete reason to prefer the list tool as a prerequisite.

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