call_ipc

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

Annotations declare readOnlyHint=false and destructiveHint=true; the description reinforces this with 'including changes', which the agent needs to know before invoking a mutation path. It also adds behavior beyond the annotations: every step is validated against the official API before anything is sent, argument types are exacted, and returned objects carry a class and uuid usable in the next call. It stops short of describing error/partial-failure behavior in a multi-step chain, which is the one real remaining gap.

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?

Front-loaded with the core action, then chaining, then validation, then the routing rule — a sensible order with no filler. It is dense (long clauses, backtick examples) but every clause carries information; only the parenthetical example chain could be trimmed.

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 low-parameter but high-power escape hatch, the definition covers the prerequisite (describe_ipc), the safety posture (reaches changes), and the round-trip object contract. An output schema exists, so return values need no explanation, and the two nested-object parameters are schema-documented. Partial-failure semantics in a chained call are the only unaddressed area.

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% and the `from`/`steps` fields are well documented in-schema, so baseline would be 3. The description adds genuine meaning on top: the chaining contract ('each on the object the previous one returned'), the root-vs-uuid distinction for the start point, and the class+uuid round-trip that makes multi-step calls possible. It doesn't restate the argument-encoding rules, which the schema already covers.

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?

States a specific verb+resource ('Call any Packet Tracer IPC method'), explains the chaining model with a concrete example (`network` -> getDevice("R1") -> getPower()), and explicitly positions itself against the many dedicated sibling tools ('Prefer the dedicated tools when one fits'). An agent can tell exactly what this is and when it is the right reach.

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?

Gives an explicit routing rule ('Prefer the dedicated tools when one fits; this reaches everything else, including changes') plus a prerequisite ('read describe_ipc first'). Both the when-to-use and the when-to-use-something-else conditions are stated, not inferred.

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