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 discloses case-insensitivity, which is a useful behavioral trait, but it does not mention what happens when no rows match, whether multiple rows are returned, pagination/limits, or performance characteristics. For a lookup tool with zero annotation coverage, this is insufficient.

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, compact sentence with no filler. It front-loads the core behavior (exact, case-insensitive match) and omits any redundant detail. It earns its place efficiently.

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?

With only two parameters and no output schema, the description should at least clarify expected output (single row vs. list), behavior on no match, and any column-name constraints. None of this is provided. The description is too thin for an agent to call the tool reliably without guessing.

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 compensate. It does not explain what 'column' refers to (name, index, allowed values) or the format of 'value' (exact string, wildcards, etc.). The description only restates the purpose without adding parameter-level meaning, leaving the agent to infer from parameter names alone.

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 returns rows where a column equals a value exactly, with case-insensitivity. This distinguishes it from siblings like dataset_search (which implies fuzzy matching), though it lacks a verb phrase like 'retrieve' or 'look up' — the title provides that. It is specific about the resource (Enpso dataset) and the operation.

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 phrase 'exactly (case-insensitive)' implies usage for exact-match lookups, contrasting with a search tool. However, it does not explicitly mention when to use this vs. alternatives (e.g., 'use dataset_search for partial matches'), nor any prerequisites or exclusions. The guidance is implicit rather than explicit.

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