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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds one useful behavioral detail—'citation-ready links'—but does not describe result format, ordering, or pagination. Given the annotations, this is adequate but not rich.

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 concise, front-loaded sentence with no filler. It efficiently lists the content domains and the citation-link benefit. It could add sibling differentiation or mention optional filters, but that is more of a completeness concern than a conciseness issue.

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 description is serviceable for a read-only search tool: it names the domains and output outcome, and the schema covers parameters. However, there is no output schema and no guidance on selecting this tool over find_housing or find_jobs, so an agent still faces meaningful ambiguity.

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 input schema describes query, lang, and intent, but the limit parameter has no description beyond min/max constraints. The tool description adds no parameter-level meaning. With 75% schema coverage, the schema does most of the work, so a mid-range score is appropriate.

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 uses a clear verb ('Search') and names the resource (Pionra) plus the covered content types: guides, housing, jobs, communities, events, and directory pages. It is clear, but it does not explicitly differentiate itself from specialized siblings like find_housing or find_jobs; the broad scope is implied rather than contrasted.

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?

No guidance is given about when to use this broad search tool versus the specialized sibling tools. The description implies the multi-category scope, but it does not state exclusions or name alternatives, leaving the choice to inference.

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