simulate

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

With no annotations and no additional description, the tool's side effects are completely undisclosed. It does not state whether the simulation mutates the world state, whether it is reversible, what triggers are needed, or what the response contains. For a simulation tool, this is a significant transparency 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?

The description is a single sentence and technically concise, but it is underspecified to the point of being unhelpful. It lacks necessary details about behavior and usage, so it is not 'appropriately sized' for a tool with this complexity.

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?

Given the tool has 7 parameters, no annotations, and no output schema, the description must carry significant burden. It fails to explain what simulation does, how parameters like stepSize and complexity affect the outcome, or what happens to the world state. The schema descriptions are insufficient without contextual behavior.

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 description coverage is 100%, with all seven parameters having descriptive text. The description itself adds no parameter information, but since the schema fully documents parameters, a baseline score of 3 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 'Run simulation forward in time' clearly states the action (Run) and resource (simulation), with a temporal scope. However, it does not differentiate from siblings like getTimeline or getWorldState, which could be confused for retrieving simulation results.

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?

No guidance is provided on when to use this tool versus alternatives such as getTimeline or initializeWorld. There are no prerequisites, exclusions, or examples of appropriate use cases.

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