zabbix_link_templates_to_host

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states the action without mentioning side effects (e.g., host inherits items/triggers from templates), permissions required, error conditions, or whether the operation is idempotent. This is critically 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 concise sentence with no redundant words. It effectively communicates the core action, though it lacks structured elaboration. Efficiency in length is a positive, but there is room for more useful detail without bloat.

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 that this is a mutation operation with no annotations and no output schema, the description is incomplete. It fails to explain the operational context, such as whether linking templates adds to or overwrites existing links, or the impact on host monitoring. The low complexity of the parameters partially mitigates, but behavioral gaps remain significant.

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 provides 100% description coverage for both parameters (hostid and templateids), so the description adds no additional parameter-level meaning. The baseline of 3 applies because the schema already documents the parameters well.

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 primary action: 'Link templates to a host in Zabbix' — a specific verb and resource that distinguishes it from the sibling unlink tool. However, it lacks scoping details such as whether linking appends to or replaces existing templates, which would make the purpose fully precise.

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?

No guidance is provided on when to use this tool versus alternatives like zabbix_host_update or zabbix_unlink_templates_from_host. There are no prerequisites, constraints, or contextual hints, leaving the agent to infer usage from the name alone.

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