Search Datasets

search_datasets
Read-onlyIdempotent

Search City of Fairfield GIS open geospatial datasets (parcels, zoning, public works & city services) 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.

Example tool call

This call uses example arguments supplied in the tool’s input schema.

  "params": {
    "arguments": {
      "query": "parcels"
    },
    "name": "search_datasets"
  }
}

Input Schema

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already indicate read-only, open-world, and idempotent behavior. The description adds value by explaining the return fields (name, summary, record_count, owner/org, Feature Service url) and the linkage to query_layer/layer_info. This goes beyond the annotations without contradicting them.

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?

Two sentences with a clear front-loaded purpose, followed by return-value details and usage guidance. Every word contributes, and the structure is easy to scan.

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

Completeness4/5

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

With no output schema, the description compensates by enumerating the return fields and their role in the workflow. It covers the essential behavior for a search tool, though it omits minor details like result ordering or pagination, which are not critical given the simple interface.

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?

Schema description coverage is 100%, with all parameters (query, limit, org_id) already described in the input schema. The description adds context by listing example data categories ('parcels, zoning, public works & city services') but does not enhance parameter understanding beyond the schema. Baseline 3 is appropriate.

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 clearly states the verb 'Search' and the resource 'City of Fairfield GIS open geospatial datasets' with specific examples (parcels, zoning, public works & city services). It distinguishes itself from sibling tools like query_layer and layer_info by noting that this tool returns dataset metadata and a Feature Service url to pass to those 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?

Provides clear context for use: 'by keyword' and states that the returned url should be passed to query_layer / layer_info, which highlights how it fits into a workflow. However, it does not explicitly state when not to use this tool versus alternatives, so it stops short of a 5.

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