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

Annotations already declare this as a safe, read-only, non-destructive operation, so the bar for behavioral disclosure is lower. The description adds the useful ordering behavior ('newest first') but does not mention pagination behavior despite pageSize and pageToken parameters.

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 front-loaded sentence with no wasted words. The key resource and ordering behavior are both stated immediately.

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 has an output schema and read-only annotations, which reduces what the description must cover. However, for a paginated list operation, the description is incomplete because it says nothing about pagination controls, page size limits, or company scoping.

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 only 50%, and the description only implicitly maps to the required schemaDefinitionId parameter. It does not explain pageSize, pageToken, or companyId semantics, leaving pagination and tenant scoping unclear from the description.

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: it lists a definition's versions. The ordering detail ('newest first') further clarifies the operation. It does not explicitly distinguish itself from the singular sibling schema_get_schema_version, so it falls just short of 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?

There is no explicit guidance on when to use this tool versus alternatives such as schema_get_schema_version or schema_get_schema_definition. The use case is only implied by the verb 'List' and the resource 'versions'.

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