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

No annotations are provided, so the description carries the burden. It implies a read-only lookup (definitions and examples) but does not state side effects, rate limits, or return format details. Since it's a simple query tool, the lack of explicit behavioral disclosure is a moderate gap.

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 a single, front-loaded sentence that captures the essential function with no wasted words. It is concise and efficiently structured.

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 low-complexity tool with one parameter and an output schema, the description is adequate but not complete. It lacks an explicit statement that 'q' is the term to query, which an agent would need to call it correctly. The output schema covers the return format, but input semantics are underspecified.

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%, so the description must clarify the parameter. It does not explicitly state that 'q' is the term to look up, though it is implied by the tool's purpose. The description partially compensates but leaves the mapping implicit, which is a gap for a single-parameter tool.

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 clearly states the tool provides 'Slang/term definitions + examples' from Urban Dictionary, specifying the resource and the action. It is distinct from sibling tools, which are mostly technical lookups or utilities, so an agent can immediately identify this as a slang dictionary lookup.

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 implies it is for looking up slang terms, but does not explicitly state when to use it over alternatives or any exclusions. No guidance is given on context, such as when a standard dictionary would be more appropriate, leaving usage partially inferred.

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