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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does disclose a non-obvious behavior—case-insensitive matching—which adds value. It does not mention how multiple matches are returned, edge cases, or any access/usage limitations.

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 with no filler. It states the core behavior and the important matching semantics efficiently, making it easy for an agent to scan.

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 straightforward two-parameter lookup, the description conveys the essential matching behavior. However, with no output schema and no annotations, it leaves return format and sibling differentiation (notably from dataset_search) implicit, which an agent would need to infer.

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?

The schema has no descriptions (0% coverage), so the description must compensate. It successfully explains that 'column' is the field to check and 'value' is the value to match exactly, which goes beyond the bare schema. It omits details like column name syntax or how the case-insensitivity affects the values, but for two simple string parameters this is adequate.

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 states a clear function: returning rows from the Intakez dataset where a column equals a value exactly, with case-insensitive semantics. It conveys a specific verb-resource combination and the term 'exactly' helps differentiate it from likely fuzzy search alternatives, though it does not explicitly name sibling tools.

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 usage context is implied through phrases like 'equals a value exactly' and 'case-insensitive', suggesting this tool is for exact-match lookups rather than searching. However, it does not explicitly state when not to use the tool or mention alternatives such as dataset_search, leaving the decision partly to inference.

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