List address groups

list_address_groups
Read-onlyIdempotent

List firewall address groups and their members to inspect group membership. Check count versus total_available and truncated status before treating results as complete.

Instructions

List firewall address groups and their members.

Compare count against total_available before concluding anything about the whole table. When truncated is present this is one page.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "list_address_groups"
  }
}

Input Schema

NameRequiredDescriptionDefault
vdomNoVirtual domain to read. Defaults to the one configured for this target. The `vdom` field in the response names the one actually read.
limitNoMaximum groups to return. Defaults to 200, capped at 1000.
offsetNoIndex to start from, for paging through a large table.
targetNoWhich FortiGate to query. Optional when only one is configured.
name_containsNoCase-insensitive substring filter on the group name.

A3.7/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false. The description adds useful behavioral context beyond annotations by explaining that count should be compared to total_available and that truncated indicates a single page, which helps the agent interpret completeness.

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?

Two sentences, front-loaded with the core purpose and followed by a high-value pagination caveat. No repetition or filler.

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

Completeness5/5

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

The tool has an output schema, so return values need not be explained. Annotations cover safety, the schema covers parameters, and the description supplies the key pagination caveat, making the definition complete for an agent to call it correctly.

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?

With 100% schema description coverage, the schema already documents all five input parameters. The description adds no input-parameter semantics; the fields it mentions (count, total_available, truncated) are output fields, not inputs.

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

Purpose4/5

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

The description states a specific verb and resource: 'List firewall address groups and their members.' It distinguishes itself from generic listing by including group members, but it does not name or compare against closely related siblings like list_address_objects.

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?

The description gives no explicit guidance on when to use this tool versus alternatives such as list_address_objects. The only practical guidance concerns interpreting pagination output, not tool selection.

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