create_vlan_interface

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

The description only states that the tool creates a VLAN interface, without disclosing side effects such as whether it fails on duplicate entries, whether it modifies live configuration, or any permission requirements. Annotations provide only destructiveHint=false, which is minimal, leaving the description to carry the burden for a state-changing device configuration 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, focused sentence of about 15 words. It front-loads the verb and key objects, contains no filler, and is easy to parse, earning every word 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 tool's complexity (10 parameters, MikroTik-specific networking semantics) and sparse annotations, a one-sentence description is inadequate. It lacks prerequisites, default behaviors, and guidance on interactions with existing interfaces or the device configuration. The output schema may document return values, but it does not compensate for missing usage context.

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?

With 0% schema description coverage and 10 parameters, the description clarifies only 'VLAN ID' and 'parent interface' for vlan_id and interface, but it ignores other parameters like arp, mtu, device, comment, disabled, arp_timeout, and use_service_tag. The agent is left to infer meanings from schema titles alone, which is insufficient for parameters like use_service_tag.

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 the specific verb 'Creates' and identifies the resource 'VLAN interface' with context 'on the MikroTik device' and key parameters 'VLAN ID and parent interface'. This clearly distinguishes it from sibling tools such as list_vlan_interfaces, get_vlan_interface, update_vlan_interface, and remove_vlan_interface.

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 implies the usage context (creating a new VLAN interface) and mentions the required VLAN ID and parent interface, but it does not explicitly state when to use this tool versus alternatives, nor does it provide exclusions or prerequisites like requiring the parent interface to exist. No reference is made to update_vlan_interface for modifications.

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