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

With no annotations, the description carries the disclosure burden but only partially meets it: it clarifies access (public, free, no key/payment), which is genuinely useful behavioral context. It does not describe rate limits, caching, or what the badge output contains, relying on the output schema for return-shape details.

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 and front-loaded, with the core action stated first and the access caveat second. The 'Args:' block is somewhat boilerplate but harmless. Nothing is padded.

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 one-param read tool with an output schema present, the description covers purpose and access needs adequately. Return values are handled by the output schema, so the absence of output description is acceptable; only the identifier format is under-explained.

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 0% and the only arg is 'tool_id'. The description does add a hint ('The tool's Wicked Registry id'), which slightly clarifies that this is a registry identifier rather than an arbitrary one, but it provides no format example or sourcing guidance. Minimal but non-zero compensation for the coverage gap.

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?

States a specific verb and resource: 'Get a tool's current composite reliability score.' This is a clear, single-purpose read operation. It does not explicitly distinguish itself from siblings like registry_tool_detail or reputation_query, but the composite-score framing is distinctive enough to infer separation.

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 'Public, free, no key or payment required' clause implies this is an open read anyone can call, which is useful context. However, it gives no explicit guidance on when to prefer this over registry_tool_detail or the reputation_* tools, leaving the choice to inference.

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