Create a client tunnel preset

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

Annotations already establish this is a non-read-only, non-idempotent write operation. The description adds that the effect is to persist a named client-to-server configuration scoped to the authenticated user, which is useful context beyond the annotations. It does not discuss duplicate-name handling, validation, or other side effects, but it does not contradict the annotations.

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 two short sentences with no filler. The action is front-loaded, and the second sentence earns its place by adding the config type and user scope.

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 create operation with a loose, completely undocumented `config` schema and no output schema, the description does not provide enough to invoke the tool confidently. It lacks guidance on the config array shape, whether parameters are effectively required, and what happens when a preset with the same name already exists.

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%, so the description must compensate for the two undocumented parameters. It weakly implies that `name` is the preset name and `config` is the tunnel configuration, but it does not explain the expected array-of-objects shape for `config`, field requirements, or valid values, leaving an agent without enough detail to construct a correct call.

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 identifies the action ('Create') and resource ('client tunnel preset'), and adds that it saves a named client-to-server configuration for the authenticated user. It does not explicitly contrast with the sibling update tool, though 'create' semantically separates it from update, list, and connect operations.

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 usage context is implied: this tool is for creating and saving a new named tunnel preset. However, the description does not explicitly say when to use it instead of update_client_tunnel_preset, nor does it state any exclusions or prerequisites.

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