reserve_ip_address

Reserve a specific or automatically selected IP address in a subnet, with optional hostname, owner, and description for IP tracking.

Instructions

Reserve an IP address in a subnet.

Args: subnet_id: Subnet ID where IP will be reserved ip: Specific IP address to reserve (optional - will find first available) hostname: Hostname for the IP address description: Description for the IP address owner: Owner of the IP address

TDQS

A4.1/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It does disclose a useful behavioral trait: the IP parameter is optional and the tool will find the first available IP. However, it omits permission requirements, conflict handling, idempotency, and effects of existing reservations, leaving significant gaps.

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

Conciseness5/5

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

The description is concise: a clear one-sentence purpose followed by a structured Args list. Every sentence and field earns its place, with no filler or redundancy.

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

Completeness4/5

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

An output schema exists, so return values need not be explained. All parameters are covered, and the optional behavior of ip is described. However, the description lacks explicit usage context such as when to prefer this over update_ip_address and what happens on conflicts, making it mostly complete but not exhaustive.

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

Parameters5/5

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

The input schema has 0% description coverage, so the description's Args list fully compensates by explaining each parameter (subnet_id, ip, hostname, description, owner). It also adds the optional auto-selection behavior for ip, providing meaning far beyond the bare schema fields.

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 begins with 'Reserve an IP address in a subnet', a specific verb plus resource that clearly identifies the operation. This distinguishes it from sibling tools like search_addresses, update_ip_address, and delete_ip_address.

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?

The description does not explicitly state when to use this tool versus alternatives such as update_ip_address, nor does it mention prerequisites or exclusions. The usage is implied by the action word 'Reserve', providing only indirect guidance.

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