firewall_list_groups

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

There are no annotations, so the description carries the behavioral transparency burden. It discloses scope ('all firewall groups in your Vultr account') and the returned key fields, which is useful. It does not state that the operation is read-only, nor does it mention pagination or empty-result behavior, though these are low-risk for a list operation.

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 concise and well-structured, with a clear opening sentence followed by a focused bulleted list of return fields. Every element earns its place and there is no redundant or promotional language.

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?

For a parameterless list operation with an output schema, the description is complete. It identifies the resource scope and enumerates all meaningful return attributes, giving an agent enough information to invoke the tool and interpret its result correctly.

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 tool has zero parameters, so there are no parameter semantics to document. The description appropriately avoids inventing parameters and instead focuses on the return fields, which fully covers the relevant input surface.

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 a specific action and resource: 'List all firewall groups in your Vultr account.' It distinguishes itself from single-group and rule-level operations such as firewall_get_group and firewall_list_rules, though it does not explicitly name those alternatives.

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 intended use is implied by the description and tool name: call this when you need the full set of firewall groups. However, it does not explicitly state when to prefer this over firewall_get_group or firewall_list_rules, leaving the routing decision mostly to inference.

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