Create EV scenario

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

Annotations declare readOnlyHint=false and destructiveHint=false, but the description adds no behavioral context beyond the bare action. It does not disclose side effects, required permissions, payload expectations, or whether the scenario is created in a draft or active state, leaving the agent without useful transparency.

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 short sentence, which is concise but also redundant with the title and tool name. It lacks substance, so while it does not contain fluff, it also fails to earn its place by adding new information beyond the structured fields.

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 create operation with an opaque payload object and no output schema, the description is severely underwhelming. It explains nothing about the payload, expected response, required context, or edge cases, leaving the agent without the information needed to use the tool reliably.

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 schema has one required 'payload' parameter with 0% description coverage, and the tool description does not mention the payload at all. The agent receives no hint about what structure or fields the payload should contain, making it nearly impossible to correctly construct the request.

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 clearly states the specific action 'Create' and the resource 'Exposure Validation scenario', expanding the 'EV' acronym. It uniquely identifies this as the creation tool for scenarios, distinguishing it from sibling tools that manage templates, smart templates, or scheduled scenarios.

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 description provides no guidance on when to use this tool versus alternatives such as cymulate_ev_scheduled_create or cymulate_ev_templates_create. There is no mention of prerequisites, use cases, or exclusions, offering no context beyond a generic create operation.

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