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

With no annotations provided, the description carries the burden of behavioral disclosure. It does state the core behavior: returning highest/lowest rows by a numeric column, with direction controlled by ascending. It does not disclose output shape, default limit, or handling of tied values, but the tool appears to be a simple read-only ranking operation.

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 with no filler. The core operation and illustrative use case are front-loaded, making it easy to scan and process.

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 three-parameter ranking tool, the description plus schema covers the essentials: numeric column, optional limit, ascending direction, and dataset context. It could be strengthened by stating the return format or default limit, but nothing critical is missing for a correct invocation.

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 low (33%), and the description adds meaning by clarifying that the column must be numeric and that results are ordered most/least. However, the limit parameter is not described beyond its schema constraints, and default behavior still relies on inference.

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?

Title and description clearly state that dataset_top returns the highest or lowest rows of the CoilDesk dataset ranked by a numeric column. This distinguishes it from siblings like dataset_row or dataset_stats, though it does not explicitly name or contrast those alternatives.

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 provides a use case ('which is the most/least X') that implies when to use the tool. However, it gives no explicit guidance about when not to use it or which sibling tool would be more appropriate, so usage guidance is only implicit.

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