get-insearch-samples

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered structurally. The description confirms it returns a sample set of currently-indexed URLs but adds nothing about pagination or result freshness. 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?

Three short sentences, front-loaded with the purpose then the exclusion rules. Slight redundancy between 'Get sample URLs appearing in search' and 'example URLs that currently appear in search', but no 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 sampling tool with no output schema and four annotations, the description covers purpose and routing well. It is incomplete on the pagination parameters and on what a 'sample' means (how many, how selected), which are the remaining gaps an agent would face.

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 only 33% (limit and offset are undocumented; host_id is merely described as 'Host ID'). The description does not compensate — it says nothing about what limit/offset mean, valid ranges, or default paging behavior. With low coverage, the description should have filled this gap and does not.

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?

States a specific verb and resource ('Get sample URLs appearing in search') and immediately distinguishes itself from close siblings by naming the alternatives. An agent can tell this apart from get-search-events-samples and get-insearch-history without inspecting schemas.

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?

Gives explicit when-to-use ('user wants example URLs that currently appear in search') and two explicit when-NOT-to-use cases, each routed to a named sibling. Routing logic is fully spelled out.

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