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

No annotations are provided, so the description carries the full burden. It states the data comes from a 'public' page, implying no authentication needed, and describes the return type as 'normalized release comparison metrics.' However, it does not disclose whether the operation is read-only, potential side effects, rate limits, or error handling.

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 extremely concise, with three short sentences that front-load the purpose and include the key usage rule. Every sentence is necessary and no words are wasted.

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?

The description adequately covers the tool's purpose and parameter selection, but with no output schema, it lacks details about the return format or structure of 'normalized release comparison metrics.' This could leave the agent underinformed about what to expect.

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%, with each parameter described. The description adds critical value by specifying that exactly one of the three parameters must be passed, which is not evident from the schema (none are required). This guides the agent on proper invocation.

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 it returns 'normalized release comparison metrics from a public Box Office Mojo showdown page,' specifying the verb and resource. Among many boxofficemojo sibling tools (e.g., boxofficemojo_brand, boxofficemojo_calendar), 'showdown' uniquely identifies this tool's focus.

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 instructs to 'pass exactly one of `id`, `path`, or `url`,' which is a clear usage rule for parameters. However, it does not provide context on when to use this tool versus alternatives or when not to use it, leaving the agent to infer from the name and sibling list.

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