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

Annotations already communicate that this is a safe, idempotent, read-only operation against a closed world. The description adds the important workspace-boundary context, but it does not describe not-found behavior, authorization expectations, or the shape of the returned simulation.

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?

It is a single, front-loaded sentence with no filler. The only minor weakness is that it may be too terse for an agent needing to distinguish this getter from adjacent simulation-related getters.

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 simple one-parameter getter with rich annotations and complete schema coverage, the description is adequate. Still, it omits what the returned simulation represents and how it differs from related simulation resources, leaving some ambiguity in a crowded sibling set.

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 input schema has full description coverage for the single id parameter and documents it as a resource identifier from a previous request. The description does not add any parameter meaning beyond that, which is appropriate but not value-adding.

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 uses a specific verb and resource ('Get one simulation') and adds a workspace-scoping constraint. It does not explicitly distinguish this tool from sibling getters such as get_simulation_run, get_simulation_persona, or get_simulation_scenario.

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 use case is implied: retrieve a single simulation by its id. However, there is no explicit guidance on when to use this instead of list_simulations or the related simulation-run/persona/scenario getters.

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