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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds the useful scoping detail that results are limited to the authenticated workspace, which tells the agent it cannot query across tenants. It does not disclose whether results are paginated, ordered, or capped, which are the remaining behavioral unknowns for a list operation.

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?

A single front-loaded sentence with no filler, hedging, or restatement of the tool name. Every element (verb, resource, scope) earns its place.

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 zero-parameter, read-only list tool with an output schema absent but a trivially predictable return shape, the description plus annotations cover what an agent needs in order to call it correctly. The only omission is result pagination or ordering behavior, a minor gap at this complexity level.

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 tool takes zero parameters, so the schema carries no semantics an agent could miss and the baseline is 4. The description correctly indicates the only implicit filter, workspace membership, rather than suggesting any arguments the agent might try to pass.

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 gives a specific verb (List) and a specific resource (simulation scenarios) scoped to the authenticated workspace, which cleanly separates it from create/update/delete_simulation_scenario and get_simulation_scenario. It stops short of distinguishing it from nearby list siblings such as list_simulation_runs, list_simulation_personas, and list_simulations, relying on the resource name alone to do that work.

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 intent (enumerate scenarios) is implied clearly by the verb plus the sibling set, which contains the singular get_ variant for fetching one item. However, there is no explicit guidance on when to prefer this over get_simulation_scenario or list_simulations, and no mention of exclusions or prerequisites.

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