zabbix_host_create

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the high-level action and does not mention idempotency, failure behavior if the host already exists, required permissions, or any side effects. This is insufficient for a mutation tool.

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. It efficiently communicates the core action and key components.

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 schema handles parameter-level detail, so the description need not repeat that. However, for a complex creation tool with 16 parameters and no output schema, the description omits behavioral context (e.g., what happens on conflict, whether it's atomic, any prerequisites) and does not mention other important aspects like TLS, proxy, or inventory from the schema. It is minimally viable but leaves gaps.

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 schema already provides comprehensive descriptions for 81% of parameters. The description adds conceptual grouping (groups, interfaces, optional templates/macros) which slightly helps, but this largely repeats what the schema already conveys through required fields and parameter names.

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 action ('Creates') and the resource ('a new host in Zabbix'), and specifies key components (groups, interfaces, templates/macros). It distinguishes itself from sibling tools like zabbix_host_update and zabbix_host_delete by focusing on creation of a new host.

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 usage is implied by the word 'Creates'—this tool is for creating new hosts. However, there is no explicit guidance on when to use this versus alternatives (e.g., use update for existing hosts), nor any mention of prerequisites such as ensuring groups or templates exist.

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