user_create

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

Annotations (all false) provide no safety signals, so the description carries the full burden of behavioral disclosure; however, it merely restates the tool's purpose without adding context about side effects, permissions required, validation rules, or creation behavior. It offers minimal guidance beyond what the name implies.

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?

Two short sentences with zero redundancy. The description is front-loaded with the primary action and then elaborates concisely. Every word 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?

Given the schema thoroughly documents all 6 parameters and an output schema exists, the description covers the essentials for a create operation. However, it could have been richer by noting side effects or prerequisites given the complete lack of annotation-based safety signals.

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%, so the schema already documents all parameters. The description adds no parameter-level details, but per the baseline rule for high coverage, no further compensation is required, though the description could have highlighted the roleid nuance.

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 a specific verb ('Create'), a specific resource ('a new user in Zabbix'), and outlines what the operation accomplishes ('with specified credentials, role and group membership'). It is immediately distinguishable from sibling tools like user_update and user_delete.

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 purpose implicitly conveys when to use this tool (to create users), but there is no explicit when-to-use vs alternatives guidance. Some context is provided by the mention of 'credentials, role and group membership', though no exclusions or direct sibling comparisons are given.

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