create_creature

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

No annotations are provided, so the description carries the full behavioral burden. It only restates that a creature is created and does not disclose what happens with the required campaignId/data, whether the operation is reversible, what response to expect, or any validation or permission concerns.

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 extremely short and front-loaded with no filler, but it is closer to under-specification than effective concise documentation. Every word earns its place, yet the overall content is not appropriately sized for a tool with a nested data object and no annotations.

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 mutation tool with no annotations, no output schema, and an opaque nested data parameter, this description is inadequate. It names the resource and action but leaves almost all invocation details unspecified, so an agent cannot reliably construct a correct call.

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 mentions neither campaignId nor data. The description adds no meaning beyond the schema's bare property names, leaving the agent unable to understand what data should contain or how campaignId relates to the new creature.

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 states a specific verb and resource: 'Create a new creature.' It is clear about the operation and entity, though it does nothing to differentiate itself from sibling create_* tools beyond the resource noun in its own name.

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 given about when to use this tool versus alternatives, when not to use it, or what prerequisites exist. With many sibling create_* tools, an agent receives no routing help beyond the resource name itself.

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