transport_set_loop_mode

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

With no annotations, the description carries the behavioral disclosure burden. It accurately states that this is a state-setting operation on the loop mode, but it does not mention potential side effects, whether the mode is set absolutely or toggled, or how it affects playback. It is adequate but not richly transparent.

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, direct sentence with no unnecessary words. It front-loads the verb and the resource, and every part contributes to understanding the tool's 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 such a simple tool—one enum parameter, no output schema, no annotations—the description is nearly complete. It clearly identifies the operation and the values involved. It omits return behavior, but that is not critical for a simple setter, and the schema already enumerates valid inputs.

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 schema provides an enum with 'song' and 'pattern', but has 0% description coverage. The description mentions 'song/pattern loop mode,' which partially ties the parameter to its values, but it does not explain what song mode versus pattern mode means or the consequences of each. Some compensation for the schema gap, but not full.

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: 'Set FL Studio's song/pattern loop mode.' It uses a specific verb ('Set'), names the resource ('FL Studio's loop mode'), and distinguishes this tool from transport siblings like transport_play, transport_record, and transport_set_position by focusing on the song/pattern loop mode.

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 makes the tool's role obvious (set loop mode), so an agent can infer when to use it. However, it provides no explicit guidance on when to use this tool versus alternatives, no exclusions, and no context about how it interacts with other transport tools. Usage context is implied rather than stated.

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