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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. The description adds value by detailing the return payload (name, summary, record_count, owner/org, url) and the workflow of using the url with query_layer/layer_info. No contradictions with 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 two sentences, front-loaded with the action and resource, then followed by output specifics and next steps. Every word earns its place, with no redundancy or filler.

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 read-only search tool with full schema coverage and no output schema, the description sufficiently covers the purpose, return fields, and downstream usage. It lacks some details like pagination or error handling, but these are not critical given the tool's simplicity. The mention of query_layer/layer_info adds valuable contextual workflow.

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 coverage is 100%, with all three parameters (limit, query, org_id) already described. The description adds minimal semantic value beyond the schema, mentioning keyword search but not providing additional syntax or edge-case details. Baseline of 3 is appropriate given high schema coverage.

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 a specific verb (Search), a resource (Lincoln County GIS open geospatial datasets), and a scope (parcels, addresses, zoning & public works). It distinguishes from siblings by mentioning follow-up tools query_layer/layer_info, indicating a unique role in the ecosystem.

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 clear context for when to use the tool (searching GIS datasets by keyword) and explicitly instructs to pass the returned url to query_layer/layer_info. It does not, however, explicitly state when not to use it or compare to alternative discovery tools like discover_tools or search_within.

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