+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare safety (readOnlyHint, idempotentHint). The description adds what the tool returns (dataset_ids, titles, themes, record counts) and the regional scope, which is helpful beyond annotations.
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, well-structured sentence that front-loads the purpose and includes key details without unnecessary words.
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?
Given the simple schema and no output schema, the description adequately covers the search scope, return values, and how results link to other tools, making it complete for basic usage.
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 covers all 3 parameters with 100% description coverage. The description does not add new details about parameters, so baseline score applies.
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 searches for datasets by keyword in a specific open data portal, listing example themes and return fields. It distinguishes from sibling tools like dataset_info by noting that dataset_ids can be passed to them.
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 implies usage for keyword-based discovery and references downstream tools for IDs, giving context. However, it does not explicitly state when to avoid this tool or directly compare with all siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
