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

No annotations are provided, so the description carries the burden. It implicitly conveys a pure read operation with no parameters and no side effects, which is reasonable disclosure for a zero-arg introspection tool, but says nothing about cost, caching, or whether output is static or refreshed.

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 short sentences, zero filler, with the content list front-loaded and the usage directive placed last where it belongs. Every clause earns its place.

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 no output schema and no parameters, the description must name the return fields, which it does exhaustively (columns, numeric classification, row count, provenance banner). It is close to complete; only the relationship to overlapping siblings is missing.

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 tool takes zero parameters, so there are no parameter semantics to document; baseline 4 applies. The description correctly does not invent or discuss arguments.

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?

States the specific resource (the Contractor Lead Quotes dataset) and enumerates the returned content: columns, numeric flags, row count, provenance banner. It is clear against most siblings, though the 'provenance banner' overlap with the sibling dataset_provenance is not resolved.

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?

'Call this first to learn the schema' gives an ordering hint, which is genuine usage guidance. However, it does not say when to prefer dataset_stats (row count overlap) or dataset_provenance (provenance banner overlap), both of which appear to duplicate part of this tool's output.

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