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

Since no annotations are provided, the description carries the full burden of behavioral disclosure. It does disclose the exact, case-insensitive matching behavior, but it does not mention whether multiple matching rows are returned, whether the operation is read-only, or how no-match cases are handled.

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 sentence that front-loads the resource, the operation, and the key matching behavior. There is no filler or redundant content.

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 two-parameter lookup, the core semantics are present, but the absence of output schema and the lack of guidance on return cardinality, no-match behavior, or when to prefer dataset_search leaves notable gaps. An agent would need additional information to confidently handle edge cases.

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 add meaning to the parameters. It indicates that one parameter is a column name and the other is the value to compare, and it adds the case-insensitive behavior. However, it does not explicitly name the parameters or describe expectations such as column name format or value matching syntax.

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 that the tool returns rows from the LPreportly dataset where a column equals a value exactly, with case-insensitive matching. It conveys a specific lookup operation and distinguishes itself from the broader dataset_search sibling by emphasizing exact matching, though it does not explicitly name siblings.

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 exact-match and case-insensitive wording implies when this tool is appropriate, but the description does not explicitly state when to use it versus alternatives like dataset_search, nor does it provide any exclusions or conditions. This makes usage guidance mostly inferential.

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