Apply Device Configuration

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

Annotations already mark this as destructive and not read-only, and the description aligns with that without adding extra context about side effects, prerequisites, or error behavior. It does not contradict the annotations, but also does not disclose anything beyond the schema/annotations, so the additional value is minimal.

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 brief and front-loaded, with the core action in the first sentence. The second sentence adds context about automated provisioning but is somewhat generic; however, there is no wasted or redundant wording.

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 simple two-parameter tool with an output schema and annotations indicating destructive behavior, the description provides enough context to understand the tool's purpose and effect. It does not explain prerequisites or return values, but those are covered by the schema and output schema, so the description is sufficiently complete.

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 100% with clear descriptions for both 'device' and 'config', so the schema carries the parameter documentation burden. The description adds generic context about applying configuration but does not provide additional detail on formats, constraints, or examples beyond the schema.

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 'Apply configuration commands to a network device' with a specific verb and resource, distinguishing it from sibling tools like run_command or get_device_configuration. The title reinforces the action, making the tool's purpose unambiguous.

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 use for automated provisioning and configuration updates, but it does not explicitly contrast with sibling tools like run_command or state when not to use this tool. No exclusion criteria or alternative tool references are provided, so usage guidance is only implicit.

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