create_actor

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

No annotations are provided, so the description must disclose behavioral traits. It only states that an Actor is created under a parent, but does not mention side effects, validation requirements (e.g., parent must exist), error handling, or permissions. The description is too thin for a mutation tool.

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 with no extraneous content. It is efficient and front-loaded with the key action, though it could be slightly more informative without sacrificing conciseness.

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 two required parameters and no annotations, the description is incomplete. It does not specify whether parent_id must exist, what happens on failure, or what the output contains (though an output schema exists, its contents are not described). An agent would lack critical context for correct invocation.

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%, so the description must compensate. It adds only that the element is created 'under parent_id', implying parent_id is the parent element, but does not explain name semantics (e.g., uniqueness, format) or any constraints on parent_id. Minimal value added beyond the schema.

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 action (Create), the resource (Actor element), and the context (under parent_id). It distinguishes itself from sibling create_* tools by specifying 'Actor' as the element type, making its purpose unambiguous.

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 implies usage for creating an Actor element specifically, but it does not explicitly say when to use this tool versus alternatives like create_element or other create_* tools. Given the many sibling create_* tools, some explicit guidance would help, but the element type provides enough implicit context.

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