winops_accounts_add_user

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

Annotations are all false, giving no positive safety profile, so the description carries the full burden. The tool discloses its return format {"success": bool, "username": str} and provides a usage example, which is mildly informative, but it says nothing about what happens on duplicate usernames, permission failures, password complexity enforcement, or other side effects. For a mutating, security-relevant operation, this is a significant gap.

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 model of conciseness: a single front-loaded purpose sentence, a clearly labeled Return Format JSON block, and one example call. Every element earns its place with no filler or redundancy, making it highly digestible for an agent.

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 2-parameter tool with complete schema coverage, the description is serviceable: it provides purpose, return contract, and an example. However, it falls short of full completeness by omitting error-handling behavior (e.g., behavior when the user already exists — especially relevant given idempotentHint: false), privilege requirements, and post-creation side effects. These would elevate it to a 4.

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 100% ('Initial password.' and 'New user account name.'), so per the rubric the baseline is 3. The example add_user(username="jsmith", password="P@ssw0rd!") hints that complex passwords are valid but doesn't add real semantic meaning beyond the schema (e.g., no format constraints, length limits, or special handling).

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 opening sentence, 'Create a new local Windows user account,' provides a specific verb (Create), a clear resource (local Windows user account), and a scope marker ('local'). This clearly differentiates it from similar account-management siblings like winops_accounts_remove_user, winops_accounts_set_password, and winops_accounts_list_users. It doesn't earn a 5 because it doesn't explicitly name an alternative tool or contrast its purpose the way the get_calls example did.

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 when-to-use or when-not-to-use guidance. There is no mention of prerequisites (e.g., admin rights), exclusions (e.g., not for domain accounts), or alternatives among the many sibling tools (remove_user, set_password, manage_group). The only implicit usage signal is the word 'local,' which hints at scope but isn't a substitute for explicit guidance.

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