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

With no annotations, the description carries the full burden of behavioral disclosure. It only states that the tool is a catalog and says nothing about read-only behavior, side effects, output format, or how the given parameters relate to the catalog.

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, but brevity here is under-specification rather than efficient writing. It fails to include any actionable or contextual information that would justify its place in a tool definition.

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 tool with four optional parameters, no annotations, and no output schema, a one-line noun phrase is far too incomplete. The agent cannot determine what input it should pass, what it will receive back, or why the sibling tools exist.

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 schema already documents all four parameters. However, the description adds no semantic connection between these parameters (url, host, json, zone) and the stated purpose of HTTP status codes, leaving the agent to guess how they are used.

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 names a specific resource (HTTP status codes), but is a noun phrase ('Short catalog...') with no actionable verb. It does not say whether an agent should look up, list, or interpret status codes, and the schema params (url, host, json, zone) suggest additional functionality that the description never acknowledges.

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?

There is zero guidance about when to use status-catalog versus its siblings (citation, compatibility, validate, etc.). No context, prerequisites, or excluded use cases are mentioned.

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