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

The description discloses that this is a write operation and that confirmation is required, which is useful behavioral context given there are no annotations. However, it does not explain side effects, whether changes are reversible, what confirmation entails, or what happens on success or failure.

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, front-loaded sentence with no wasted words. It is appropriately brief, though brevity comes at the cost of needed detail.

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 write tool with five undocumented parameters, no annotations, and no output schema, this description is far too thin. It leaves essential information about parameters and confirmation behavior entirely to inference.

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 0%, and the description provides no meaning for any of the five parameters (index, param, user_code, confirm_token, confirmation_id). An agent has no way to know what values to supply or how they relate to the confirmation flow.

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 names a specific action ('Configure') and a specific resource ('a VPN profile'), so an agent can identify the tool's core function. It does not explicitly differentiate from siblings like vpn_ovpn or vpn_dial_out, but the phrasing is clear enough.

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?

There is no guidance about when to use this tool instead of alternatives such as vpn_remote, vpn_ovpn, or vpn_list. The parenthetical 'requires confirmation' hints at a workflow constraint but does not explain prerequisites or selection criteria.

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