Search Datasets

search_datasets
Read-onlyIdempotent

Search Palm Beach County GIS open geospatial datasets (parcels, addresses, zoning & public works) by keyword. Returns each dataset's name, summary, record_count, owner/org, and its Feature Service url — pass that url to query_layer / layer_info.

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already establish read-only, idempotent, open-world behavior. The description adds value by specifying the output fields (name, summary, record_count, owner/org, Feature Service url) and the open-data scope, which goes beyond the structured annotation data.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences long, front-loads the action and resource, then states the return value and next steps. No wasted words; every phrase adds meaningful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a search tool with optional parameters, no output schema, and annotations covering safety, the description is effectively complete. It explains what is searched, what is returned, and how to use the result, making it self-sufficient for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All three parameters (query, limit, org_id) have descriptions in the input schema covering 100% of them. The description's mention of 'keyword' only paraphrases the query parameter without adding any new semantic detail. Baseline of 3 is appropriate given full schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Search') and resource ('Palm Beach County GIS open geospatial datasets'), names concrete dataset categories (parcels, addresses, zoning), and clarifies its role by pointing to query_layer/layer_info for further use of the returned URL. This clearly distinguishes it from sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context: it is for keyword discovery of GIS datasets. It also advises passing the returned Feature Service URL to query_layer/layer_info, which serves as a next-step guideline. However, it does not explicitly state when NOT to use this tool or mention alternatives beyond those two.

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