get_fx_preset

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

The readOnlyHint annotation already signals a safe read operation. The description adds that the return value is an object containing the current preset name, which is useful. However, it does not disclose behavior for invalid indices or whether the preset name can be null.

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 short and front-loaded with the core purpose. The return line is slightly redundant but adds a small amount of structural information without waste.

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 getter with a readOnly annotation, the return shape is mentioned, but the complete absence of parameter semantics and usage guidance leaves an agent uncertain about how to invoke it correctly. No output schema exists to fill the gap.

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%, and the description does not explain what track_index and fx_index mean, their indexing origin, or how they identify the target FX. The description entirely fails to compensate for the schema's lack of parameter documentation.

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 operation ('Get') and the resource ('current preset name of an FX'), which distinguishes it from plural-oriented siblings like get_fx_presets. It does not explicitly specify track FX versus take FX, but the required track_index parameter implies track context.

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?

No guidance is provided about when to use this tool versus alternatives such as get_fx_presets, set_fx_preset, or track_fx_get_name. The description does not mention exclusions, prerequisites, or context for choosing this getter.

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