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

The description discloses important behavioral details beyond the annotations: it inherits actor, story casting, cue, emotion, and line unless overrides are supplied, and preserves parent/root ids and the director note. This adds context about data flow and side effects. The annotations (readOnlyHint=false, destructiveHint=false) align with the create operation, and there is no contradiction.

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 compact and information-dense, consisting of two sentences that front-load the primary action ('Create a child take') and then efficiently list inheritance and preservation behavior. Every clause adds value without redundancy.

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-type tool with no output schema, the description sufficiently covers the essential behavior: what is created, what is inherited, and what is preserved. It does not explain the return value or potential side effects, but the annotations and schema fill in some gaps. Overall, it is complete enough for an agent to decide when and how to 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?

With schema description coverage only at 17%, the description partially compensates by explaining that optional parameters (cue, emotion, line) serve as overrides and that parent/root ids are preserved. However, it does not clarify the role of direction_notes (whether it is inherited or new) or fully explain the relationship between parent_audition_id and the created child take. The description adds some meaning but leaves gaps.

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 a child take from an existing audition.' This uses a specific verb and resource, and the phrase 'from an existing audition' distinguishes it from sibling tools like 'audition' (creating a new audition) and 'delete_audition'. The purpose is unambiguous and immediately actionable.

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 provides clear context for when to use the tool: whenever a new take based on an existing audition is needed. It does not explicitly mention alternatives or when not to use it, but the context is strong enough for an agent to infer the appropriate situation. Lack of explicit exclusions prevents a 5.

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