Describe a Packet Tracer IPC Class

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds real value beyond that by disclosing that results include inheritance, method signatures, parameter/return types, and the ExApp privilege required per method — a behavioral trait (privilege gating) that would otherwise be invisible.

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?

One sentence of specification followed by two compact examples; the output contract and the companion tool are front-loaded, and nothing is repeated from the schema.

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?

With an output schema present, the return values need no elaboration, and the examples cover the main ambiguity (which class_name to use). It stops short of stating any precondition such as needing an active Packet Tracer session, which is the only notable gap.

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%, so the baseline is 3; the description earns an extra point by demonstrating real argument values (class_name="OspfProcess", class_name="Port", name_filter="mac"), which clarifies that both class names and filters are arbitrary substrings rather than the enum-like lists in 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 states a precise verb and resource: 'Show an IPC class's inheritance and method signatures, (param types) -> return type plus the ExApp privilege each needs.' It even defines the output shape inline, and no sibling tool overlaps with class introspection, so disambiguation is implicit but complete.

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?

'Use with call_ipc_api' establishes the workflow context in which this tool belongs, and the two examples show how a natural-language question maps to arguments. There is no explicit when-not guidance or named alternative, but the pairing instruction gives an agent enough to place the call.

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