boxofficemojo_weekend_domestic_estimates

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

With no annotations, the description carries the full burden. It discloses the return type (estimate-vs-actual rows) and error behavior for empty pages. However, it does not mention rate limits, authentication, pagination, or data freshness limits, which are important for an agent to know.

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?

Two sentences, no extraneous words. The main purpose is front-loaded, and additional information about error behavior is efficiently provided.

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 explains what the tool returns and one edge case, but without an output schema, it lacks details on the structure of the rows (e.g., fields, data types). For a tool that returns rows, more context would be beneficial. Adequate but not fully complete.

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 parameter descriptions already explain 'weekend number' and 'year range'. The tool description adds no further detail beyond the schema, so it meets the baseline but does not enhance understanding.

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 estimate-vs-actual rows from Box Office Mojo's domestic weekend estimates chart. It distinguishes from siblings like boxofficemojo_weekend_domestic by specifying 'estimates' and the nature of the data. The mention of error behavior adds clarity.

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 usage for estimate-vs-actual comparisons, which differentiates it from the sibling boxofficemojo_weekend_domestic. However, it does not explicitly state when not to use it or provide direct alternatives. The error behavior note is helpful but not a full guideline.

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