deploy_list_regions

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the basic function and does not mention pagination behavior, rate limits, idempotency, or what happens with empty results. The schema implies pagination via page and limit parameters, but the description adds no value beyond that.

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 a single sentence that is concise and front-loaded with the key action and resource. No extraneous information.

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?

The tool has no output schema and no annotations. The description does not explain what the return value contains (e.g., region IDs, names, status), which is essential for the agent to process the response. Given the simplicity of a list operation, the description is incomplete.

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?

Schema description coverage is 67% (2 of 3 parameters have descriptions), which is moderate. The description does not mention any parameters or add meaning beyond what the schema provides. The name_filter parameter lacks a description in the schema, and the description does not compensate for this gap.

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 the verb 'List' and the resource 'Cisco Secure Access regions' with a specific context 'available for Network Tunnel Group placement'. This distinguishes it from sibling tools like deploy_list_networks and deploy_list_network_tunnel_groups.

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 description implies usage for listing regions but provides no explicit guidance on when to use this tool vs alternatives, nor any when-not-to-use scenarios. The context is clear from the resource name but lacks exclusionary criteria.

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