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

With no annotations provided, the description carries the full burden. It discloses important behavioral traits: copies all dependencies (notes, events, audio files), shares preserved resources rather than duplicating them, supports delete_source for move semantics, and reports the new region's type/position/duration or error. This is valuable and goes beyond a simple mutation statement.

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 well-structured: a one-line summary, a behavior paragraph, a parameter list, and a return-value note. It is longer than strictly necessary, but each part contributes meaningful information. The formatting is logical and front-loaded, making it easy to scan.

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?

Given the tool's complexity (7 parameters, mutation semantics, cross-AU operation) and the existence of an output schema, the description is largely complete. It covers all parameters, key behavioral nuances, and return values. It could mention failure/error conditions more explicitly, but the 'or error' note is sufficient given the output schema.

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 no property descriptions (0% schema coverage), but the description thoroughly explains all seven parameters. It adds semantics not present in the schema: region_index is 0-based and sorted by position, insert_position is in beats, and delete_source controls move vs copy. This fully compensates for the schema's lack of descriptions.

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?

Description clearly states the tool transfers/copies a region to another track at a specified position, naming the operation (TransferRegions.transfer) and key capabilities such as cross-AU support and dependency copying. However, it does not explicitly differentiate from sibling tools like copy_region_to_track or move_region_to_track, leaving some ambiguity.

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 context for usage (e.g., works across different audio units, preserved resources are shared, optional source deletion), which implies when this tool is appropriate. However, it does not explicitly state when to use this tool over alternatives or mention any exclusions, leaving the agent to infer the best choice.

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