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

Annotations already establish readOnly/non-destructive/closed-world, so the safety profile is covered. The description adds genuinely useful behavior beyond that: results are complete records including SyncToken, so an agent can skip a subsequent get call. It does not mention ordering guarantees or truncation behavior (that lives in the schema), keeping it short of a 5.

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 sentences, no filler, and the most important fact (results are complete, no get needed) is front-loaded ahead of the batch-read idiom. Every clause carries information.

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?

There is no output schema, and the description compensates by stating what comes back (full records with SyncToken). Annotations cover safety, the schema covers criteria and the 1000-record page limit, so an agent has everything needed to call this correctly.

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 baseline is 3 and the criteria syntax, operators, and pagination rules are already documented there. The description still adds meaning by giving the 'Id IN' idiom for batch-fetching known records, which is a practical semantic the schema does not spell out.

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 first sentence gives a specific verb (Search) and resource (reimburse charge records) scoped to QuickBooks Online, which distinguishes it from the many get_/create_ siblings. However it never names a sibling it should be preferred over or explicitly contrasts with search_transactions-type tools, so differentiation is by naming convention only.

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?

It supplies a concrete usage rule ('read several known Ids in one search with Id IN') and explains that a follow-up get is unnecessary because results are full records. That is clear context for when this tool suffices, but there is no explicit when-not or named alternative.

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