create_snapshot

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

With no annotations provided, the description must carry the full behavioral disclosure burden. It discloses that the tool creates a full clone of the world, which is useful, but it does not mention side effects (e.g., overwriting existing snapshots, resource usage), return behavior, or snapshot lifecycle. Some context is present, but significant gaps remain.

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, concise sentence that front-loads the core purpose without any unnecessary words or filler. Every word 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?

In the context of a rich simulation toolset with many sibling operations, this description is too sparse. It does not explain how the snapshot relates to rollback operationally, whether multiple snapshots are allowed, or what the return value contains (though an output schema exists). The description leaves the agent without enough context to confidently select and invoke the tool.

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 0% and the description does not mention the 'name' parameter at all. The agent is left without any explanation of what 'name' refers to, whether it must be unique, or what happens if omitted. The description entirely fails to compensate for the lack of schema documentation.

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 ('Clone') and resource ('the complete native world') and explicitly states the purpose ('for later rollback'), making it clear what the tool does and distinguishing it from sibling tools like rollback and create_world.

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 phrase 'for later rollback' implies the tool should be used before changes that may need to be undone, but the description does not explicitly state when to use it versus alternatives like rollback or create_world. No exclusions or conditions are provided.

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