voice_open_gui

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

With no annotations provided, the description carries the full burden. It adds context about starting a subprocess to avoid blocking and lists GUI features, but it does not disclose potential behaviors like whether opening multiple instances is allowed, error conditions, or system requirements.

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?

Two efficient sentences: the first clearly states the action, and the second provides necessary details about non-blocking behavior and features. No extraneous words.

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 zero parameters and no output schema, the description covers the key aspects: purpose, non-blocking execution, and GUI features. It could improve by noting if the GUI is modal, how to close it, or behavior if already open, but it is largely complete for a launcher tool.

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 tool has zero parameters, and the schema coverage is 100%. The description explains the purpose and features beyond the empty schema, adding value by detailing what the GUI contains.

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 'Launch the interactive Voice-to-MIDI GUI' with a specific verb and resource. It distinguishes from sibling voice tools like voice_list_devices or voice_notes_to_piano_roll, which do not involve launching a GUI.

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 usage when an interactive GUI is desired but provides no explicit guidance on when to use versus alternatives, such as voice_to_piano_roll or voice_notes_to_piano_roll. No when-not or exclusion criteria are given.

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