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

The readOnlyHint annotation already establishes that this is a safe read operation. The description adds useful mode context by explaining id-based lookup versus filtered querying, but it does not describe pagination behavior, sorting/projection implications, or return shape. With annotations covering the safety profile, 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 efficient sentence with the primary lookup modes front-loaded. There is no wasted wording or redundant explanation.

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 tool is a read-only query with six optional parameters and no output schema. The description covers the two main access patterns, but it omits the fields projection parameter and does not describe return values, which are left entirely to the schema and annotations.

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 most parameters are already documented in the schema, including skip, sort, limit, and query. The description reinforces the id and query semantics but adds little beyond what the schema already says. Baseline 3 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 states a specific verb and resource: "Find LimCreateDomain records." It also distinguishes the two retrieval modes, single-record lookup by id versus filtered-list query. It does not explicitly differentiate this tool from similarly named sibling query tools, which keeps it below a 5.

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 gives clear usage guidance: pass id for one record, or use query for a filtered list. That tells the agent when to choose each mode. It does not mention alternatives or exclusions beyond those two modes, so it is not a full 5.

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