apply_ipsec_changes

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

Annotations already declare idempotentHint=true and destructiveHint=false. The description adds the concept of pending changes and batch activation, which is useful, but it doesn't elaborate on system effects, service restarts, or any potential side effects. It satisfies the baseline but doesn't add rich behavioral context beyond 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?

Two sentences, front-loaded with the primary action, and zero padding. Every word earns its place, making it very concise and well-structured.

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 zero-parameter apply-style tool with annotations and an output schema, the description covers the essential trigger condition and outcome. It doesn't explicitly exclude non-IPsec changes, but the name and scope make that unambiguous. Slightly more context (e.g., whether it applies all pending changes across modules) would elevate it to a 5.

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 input schema has zero parameters, so the description has no parameter burden. The description correctly doesn't invent parameter details, and with 100% schema coverage, the baseline for zero parameters applies.

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 ('apply') and resource ('pending IPsec configuration changes'), clearly distinguishing it from other apply_*_changes tools by scope. It also clarifies the activation mechanism (pending changes with apply_immediately=False), leaving no doubt about what the tool does.

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?

Explicitly states when to call: after making IPsec changes with apply_immediately=False, to activate them all at once. This provides clear context, though it does not explicitly name alternative apply_* tools or state when not to use it, so it doesn't reach a 5.

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