create_audio_loop

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the output is not claimed to have a seamless boundary, but it omits important behavior such as what file is written, how overwrite is handled, and whether the source audio is modified.

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 definition is two concise sentences with no wasted wording. The purpose is front-loaded, and the caveat follows immediately where it is relevant.

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?

The tool has no annotations, no output schema, and five parameters with 0% schema description coverage. The description covers the core operation and one output caveat but leaves output location, format behavior, and overwrite semantics undocumented.

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 should compensate for the five parameters. It only vaguely references the input audio and requested duration, leaving input_path, filename, format, and overwrite unexplained beyond their property names.

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: "Repeat an audio file to a requested duration." That clearly distinguishes it from sibling tools such as trim_audio, merge_audio, and split_audio, which manipulate audio in different ways.

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 the basic use case of extending an audio file to a target duration, but it gives no explicit when-to-use guidance, no exclusions, and no comparison to sibling tools. The seamless-boundary caveat is a quality note, not usage guidance.

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