configureIosDevice

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

The description adds useful non-obvious behavior: commands are executed from global config and persisted using 'write memory'. There are no annotations to lean on and the text does not disclose failure behavior, what happens on invalid commands, or whether command output is returned.

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?

Two sentences carry all essential information: action, target, execution context, and persistence behavior. There is no redundant wording or restatement of the tool name.

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 two-parameter tool with no output schema, the description covers the important factors: target device class, command type, mode of execution, and persistence. It does not mention preconditions like device existence or authentication, but these are reasonably outside the scope of a simple command execution tool.

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 coverage is only 50%, with 'commands' documented but 'deviceName' undocumented. The description adds miniature context by implying commands are IOS commands sent to a router/switch, but it does not sufficiently explain the deviceName parameter or its relationship with network inventory.

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 uses a specific verb and resource: 'Execute IOS commands' plus 'router or switch,' which makes the tool's function immediately clear. It is distinguished from the PC/IP-focused sibling (configurePcIp) by mentioning IOS and network-grade devices.

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 provides clear context about where the command run and what context they execute in, which tells an agent this is for configuring IOS networking devices rather than PCs or simulation controls. It does not explicitly name alternative tools or list negative cases, so it stops short of a full 5.

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