ue_create_level_sequence

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

Without annotations, the description carries the burden of behavioral disclosure. It mentions that the sequence is empty and that length_frames sets playback range from 0, plus a default fps of 30. However, it does not disclose side effects like whether the asset is saved, opened, or could overwrite an existing asset.

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 concise: a single-sentence purpose followed by a clean argument list. No fluff or redundant information. Every line serves a purpose.

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 simple creation tool, it covers the basic behavior and parameters, but lacks contextual details about post-creation actions (e.g., saving, opening) and how it fits among the many sequence-related sibling tools. Given no annotations or output schema, a bit more context would be warranted.

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%, but the description adds value by providing examples for package_path and name, and semantics for fps (display frame rate, default 30) and length_frames (duration in frames, sets playback range). This compensates well for the missing schema 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?

The description clearly states 'Crea una Level Sequence vuota' (creates an empty Level Sequence), using a specific verb and resource. This distinguishes it from sibling tools that edit or query sequences, such as ue_sequence_add_actor or ue_sequence_info.

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 does not provide when-to-use guidance or mention alternatives. It simply states what the tool does and lists arguments, with no context about when to choose this over other sequence or creation tools.

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