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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds genuinely useful behavior beyond that: results are complete records including SyncToken, so no follow-up get call is required, and multiple known Ids can be retrieved in one IN-filtered call.

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?

Two short sentences, zero filler, with the highest-value fact (no get needed after search) placed right after the purpose statement. Nothing is redundant.

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?

With no output schema, the description rightly tells the agent what comes back (full records with SyncToken) and how to batch-read known Ids. It is essentially complete for a paginated search tool whose filtering grammar lives entirely in the schema, though it could say more about result ordering or the pagination 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 description coverage is 100%, so the criteria grammar, AND-semantics, case-sensitivity and 1000-record pagination/truncation limits are already fully documented in the schema. The description's only added semantic is the 'Id IN' pattern, which is helpful but marginal against the baseline.

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?

It states a specific verb and resource ('Search refund receipt records in QuickBooks Online'), so the agent immediately knows this is a read/query tool for that one entity type. It implicitly separates itself from get_refund_receipt by noting results are already full records, but it never names the sibling outright, so it falls short of the clearest possible differentiation.

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 gives one concrete usage pattern ('read several known Ids in one search with Id IN') and implies that get is unnecessary after a search. It offers no explicit when-to-use guidance against get_refund_receipt or other search_* tools, and no when-not-to-use conditions.

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