D1.4/5.0
Behavior1/5

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

No annotations are provided, so the description carries the full burden of explaining behavior. It discloses no side effects, return shape, rate limits, prerequisites, or processing semantics, and it conflicts with the schema's implication that the tool performs multiple unrelated operations. The phrase "catalog" is too weak to count as behavioral disclosure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short, but it is an under-specified noun phrase rather than a helpful, structured explanation. It front-loads nothing actionable and omits essential information about the tool's interface or behavior.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With four parameters, no output schema, no annotations, and a heterogeneous set of sibling tools, this description is completely inadequate. An agent cannot determine what action to take, what inputs to provide, or what response to expect.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each parameter has a clear description in the schema itself. However, the tool description adds no meaning to these parameters and fails to connect them to the stated HTTP status code catalog purpose, leaving the overall semantics ambiguous.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description "Short catalog of common HTTP status codes" is essentially a restatement of the tool name and provides no verb or operation. It does not explain what the tool does with the supplied url, host, json, or zone parameters, and it does not distinguish this tool from siblings like http-410 or normalize-url.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus its alternatives. The description suggests a tool about HTTP status codes, while the schema clearly points to URL normalization, JSON validation, and timezone handling, which is misleading for an agent trying to select the right tool.

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