Reset the Simulation

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

Annotations declare readOnlyHint=false and destructiveHint=false; the verb 'Clear' is consistent with a write, and the description usefully narrows the blast radius by stating device configurations survive. It does not say whether cleared events are recoverable or whether simulation time restart affects pending events, which would have fully closed the loop.

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 action and its scope limit are front-loaded in the first two sentences. The example list is slightly redundant — 'Clear the event list' largely restates the opening clause — but remains short and non-padding.

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, return-value description is unnecessary, and annotations cover the safety profile. The only gap is precondition state (must Simulation mode be active?) and the permanence of the cleared events, both of which an agent could plausibly need.

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?

Zero parameters, so there is nothing to disambiguate and the baseline applies. The description's note that configurations are untouched is the only semantic context needed for a no-arg call.

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 concrete compound action — clearing the Simulation-mode event list and restarting simulation time — plus an explicit scope limit ('Device configurations are not changed'). An agent can tell this apart from get_simulation_events or step_simulation, though no sibling is named outright.

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 example utterances ('Clear the event list', 'Start the simulation over') imply when to reach for it, and the 'device configurations are not changed' line rules out config-reset intent. However, it never says whether Simulation mode must already be active, nor does it point to set_simulation_mode or step_simulation as alternatives.

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