Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description clearly discloses the read-only nature of the operation and explicitly mentions edge-case behavior (non-numeric rows are excluded and counted). No annotations exist, but the description adequately communicates the tool's behavior and output.
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, focused sentence that lists the output statistics and notes handling of formatting and non-numeric rows. No unnecessary details or redundant phrasing.
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?
The tool is simple with one parameter, and the description covers purpose, input semantics, edge cases, and output content. No additional annotations are needed for this straightforward operation.
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 single parameter 'column' is well described in the context of the operation as a numeric column of the dataset. The schema provides only a string type, but the description clarifies its semantic meaning, compensating for the sparse schema.
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 specific operation: computing summary statistics (count, min, max, mean, median, sum) for a numeric column. It distinguishes itself from other dataset tools by focusing on numeric column statistics without overlapping with row/search/top operations.
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 does not mention when to use this tool versus the sibling tools. No explicit conditions or alternatives are provided, leaving the agent to infer suitability based solely on the tool name and description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct operation: schema, provenance, exact row lookup, substring search, ordered comparison, statistics, and top/bottom extremes. dataset_row and dataset_compare are somewhat similar, but their descriptions make the single-value vs ordered-multi-value distinction clear.
All tools share the consistent dataset_ prefix and snake_case style, making the family recognizable. However, the second segment mixes noun, verb, and adjective forms (columns, compare, top), so the naming is not a strict verb_noun pattern.
Seven tools is well-scoped for a dataset querying server. Each tool covers a different common question type without redundancy, and the count feels neither thin nor bloated.
The tool set covers schema discovery, provenance, exact lookup, substring search, comparisons, summary statistics, and top/bottom ordering. For a read-only dataset QA server, there are no obvious missing operations or dead ends.
