Behavior2/5

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

With annotations readOnlyHint=false and destructiveHint=false, the tool is known to be a non-read, non-destructive operation, but the description adds no context about side effects, apply_immediately behavior, or reversibility. It merely restates the tool name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short but is essentially a tautology of the tool name. It does not add information, so it fails to earn its place as a description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has moderate complexity (members array, apply_immediately flag) and an output schema, but the description is too sparse. It doesn't explain what an interface bridge is, the effect of apply_immediately, or any prerequisites, leaving significant gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100% for all parameters, so the baseline is 3. The description adds no additional meaning beyond what the schema already provides for members, descr, and apply_immediately.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Create an interface bridge' clearly states a specific verb and resource, distinguishing it from sibling tools like search_interface_bridges and create_interface. It unambiguously indicates the tool's function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidance is provided. The description does not indicate when to use this tool versus alternatives like create_interface_group or create_vlan, nor does it mention prerequisites or conditions.

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