apply_interface_changes

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description adds that it applies pending (already-created) changes in a batch, clarifying that this is a finalization step rather than a direct mutation. This goes beyond the annotations by describing the workflow position and batch behavior.

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 effectively communicate purpose and usage with no redundancy. The first sentence is a clear headline, and the second provides actionable guidance, making efficient use of space.

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 no-parameter tool with an output schema and strong annotations, the description is sufficient. It explains what the tool does and when to call it, satisfying all necessary contextual information without over-explaining.

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?

The tool has no parameters, making the schema coverage trivially complete. The description correctly omits parameter details, and while it does not add parameter-specific information, none is needed. The baseline of 4 for zero-parameter tools is appropriate.

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 pending interface changes', identifying the specific resource (interface) and the action (apply). It distinguishes this tool from sibling apply tools such as apply_firewall_changes and apply_nat_changes, and adds the important context of 'pending' changes.

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 explicitly instructs to use this after making changes with apply_immediately=False, giving a clear trigger context for batch application. It does not list alternatives, but the named resource 'interface changes' in the tool name and description naturally separates it from other apply_* utilities.

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