Contract Testing: Admin Create System Account

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

Annotations already indicate a mutating, non-idempotent operation (readOnlyHint=false, idempotentHint=false), so the description's 'Create' confirms the action type rather than contradicting it. It adds little beyond that—no mention of auth requirements, uniqueness, side effects, or return behavior—though 'Toolset: Admin' hints at privilege.

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 short and front-loads the primary action, and the Toolset/Parameters layout is scannable. However, the Parameters block duplicates the schema, so not every part of the description earns its place.

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?

For a one-parameter creation tool, the minimum required to invoke it—action and required field—is present. Missing context about output, naming constraints, or admin permissions keeps it from being complete, but the low complexity and annotation coverage make it adequately usable.

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 already fully documents the single required `name` parameter with 100% coverage. The description's Parameters section repeats that information without adding constraints, defaults, or examples, so it meets the baseline but adds no extra semantic value.

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 uses a specific verb ('Create') and identifies the resource ('a new system account'), and the 'Toolset: Admin' heading clarifies the administrative scope. The parenthetical '(admin)' is slightly ambiguous, but the action and object are clear enough to distinguish this from most sibling tools.

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 when-to-use or alternative guidance; an agent must infer that this tool is for creating system accounts. 'Toolset: Admin' provides loose context, but it doesn't differentiate this from admin_create_user or admin_create_team or state prerequisites.

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