Contract Testing: Admin Create System Account

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

Annotations indicate readOnlyHint=false and destructiveHint=false, so the description's 'Create' verb is consistent. However, the description adds no additional behavioral context such as whether the operation requires specific permissions, is reversible, or has side effects. It fails to go beyond the annotations.

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 very short and to the point, with a clear section for the parameter. It avoids unnecessary fluff. However, it may be too terse, lacking explanatory context that could be included 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?

The tool has only one required parameter and no output schema, but the description still fails to provide essential context such as what a system account is, how it differs from a user, or any prerequisite conditions. For a creation operation, more completeness is expected.

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?

The input schema has 100% description coverage, with the 'name' parameter already described. The tool description repeats the same parameter description verbatim, adding no new semantic meaning. Baseline is 3, and no extra value is provided.

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 clearly states the verb 'Create' and the resource 'system account (admin)'. It distinguishes from sibling tools like contract-testing_admin_create_user by specifying the resource type. However, it is brief and doesn't elaborate on the concept of a system account, which might leave some ambiguity.

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 provides no guidance on when to use this tool over alternatives such as contract-testing_admin_create_user or contract-testing_admin_create_role. There is no context about prerequisites or situations where this tool is appropriate.

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