mcp_opendaw_engine_panic

Sends a panic signal to stop all notes immediately, clearing stuck audio, hanging notes, or frozen synthesis. Works like a MIDI panic button.

Instructions

Send a panic signal to the engine — stops all notes immediately.

Useful when audio gets stuck (hanging notes, frozen synthesis). Equivalent to a MIDI panic button.

A4.5/5.0

Behavior4/5

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

With no annotations provided, the description carries the burden of behavioral disclosure. It transparently states the effect: stops all notes immediately, and equates it to a MIDI panic button. It doesn't mention potential side effects on transport or engine state, but the core behavior is well disclosed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and well-structured: three short sentences that front-load the purpose, then add context and equivalence. Every sentence earns its place with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given zero parameters, no annotations, and the presence of an output schema (which likely covers return values), the description is complete. It explains the action, when to use it, and the immediate effect, making it fully self-contained for a simple no-arg tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters and an empty schema, so the baseline for parameter semantics is 4. The description adds no parameter-specific info because none is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action: 'Send a panic signal to the engine — stops all notes immediately.' This uses a specific verb (send panic) and resource (engine), and distinguishes it from sibling tools like engine_sleep or transport, which have different purposes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides explicit guidance on when to use: 'Useful when audio gets stuck (hanging notes, frozen synthesis).' While it doesn't name alternatives, the context is clear enough for this niche panic-button tool.

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