Open in SoundCraft

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

Adds real behavioral context beyond annotations: opening launches a GUI, and control=true starts a loopback-only control channel (a security-relevant detail). Annotations already cover the safety profile (non-read-only, non-destructive, not idempotent), but the description doesn't say what happens if the app is already open or what the call returns.

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 sentences, zero waste, front-loaded with the core action before the conditional control-channel detail. Nothing repeated from title or schema.

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?

No output schema exists, so the description should carry the burden of return behavior, and it does not state what the tool returns or what happens on failure/already-running app. Everything else an agent needs to invoke it correctly is present.

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 coverage is 67% and the control parameter has no schema description at all; the description compensates by explaining exactly what control=true does (starts the control channel enabling live driving). demo and path already carry schema descriptions, so this is additive rather than duplicative.

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?

Specific verb+resource ('Open a .scraft session in the SoundCraft desktop app') with scope ('to listen and keep editing by hand'), clearly distinguishing it from create_session/edit_session siblings that manipulate sessions without launching the desktop app.

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?

Names the alternative explicitly and the condition that selects it: with control=true, run_soundcraft_commands live=true can drive the app. An agent can decide between this tool and run_soundcraft_commands without inference.

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