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

The readOnlyHint=true annotation already establishes that this is a safe, non-mutating read, lowering the description's burden. The description adds the id-versus-query branching behavior, but does not discuss pagination semantics, default limits, clamping behavior, or result ordering beyond what the schema states. It adds some value but no behavioral context that the annotations or schema don't already cover.

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 definition is a single front-loaded sentence with no filler, and the two usage modes are presented in immediate succession. It is efficiently sized for the amount of information conveyed. A slightly richer second clause about default listing behavior would have improved it without harming conciseness.

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 six optional parameters, a nested query object, and no output schema, the description supplies only the id-versus-query distinction. The schema carries the rest of the load, so an agent can still call the tool correctly, but the most complex aspect - the MongoDB-style nested filter - is left entirely to the schema's single example. It is adequate rather than complete.

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 high at 83%, so each of the six parameters is already documented in the schema, including limit clamping and descending-sort syntax. The description reinforces that id selects a single record while query produces a filtered list, adding a little cross-parameter meaning. It does not, however, explain the nested MongoDB-style filter object, which is the most semantically complex parameter.

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 names a specific verb (find/query) and resource (LimGameVisit records) and splits the behavior into two concrete modes: single-record fetch by id versus filtered list retrieval via query. This is clear enough for an agent to understand the tool's function. It does not explicitly contrast itself with siblings, but the resource-scoped name and dual-mode framing make its purpose unambiguous.

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 mode-selection guidance ('pass id for one record, or query for a filtered list'), which is genuinely useful for choosing between the two invocation styles. However, it offers no when-to-use versus when-not guidance, no mention that omitting both id and query returns an unfiltered list, and no hints about prerequisites or result-size implications. Usage context is implied rather than stated.

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