A3.6/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. It identifies the operation as a deletion, but does not disclose permission requirements, irreversibility, what else may be affected in the device DB, or safeguards around destructive changes.

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

Conciseness4/5

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

The description is front-loaded with the purpose and then cleanly structured into Args and Returns. It is appropriately sized, though the vague 'Returns: Deletion result' is redundant given the output schema.

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

Completeness3/5

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

The description covers purpose, all parameters, and a minimal return statement, and an output schema exists for return details. For a destructive, unannotated mutation, however, it lacks sufficient context about safety, permissions, and when-not-to-use behavior.

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

Parameters4/5

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

With 0% schema description coverage, the description documents all three parameters: device as the managed device name, dhcp_server_id as a numeric scope id with a pointer to list_device_dhcp_servers, and vdom with its default of 'root'. This adds useful meaning beyond the schema types.

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 states a specific verb and resource: delete a DHCP server scope from a device's device DB. It is clearly distinct from sibling tools like list_device_dhcp_servers, create_device_dhcp_server, and update_device_dhcp_server.

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

Usage Guidelines3/5

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

Usage is implied by the verb 'delete' and by the reference to list_device_dhcp_servers for obtaining the scope id. However, there is no explicit guidance on when to use this tool versus update or list, and no prerequisites or exclusion cases are stated.

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