mcp_opendaw_set_clip_mute

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

No annotations are provided, so the description must disclose behavioral traits. It states that the tool returns old and new mute state, but does not mention potential side effects (e.g., affecting playback, or if the mute is independent of other muting mechanisms). It does not describe error handling for invalid indices. Transparency is adequate but not comprehensive.

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 (3 sentences) and well-structured: first sentence states purpose, second explains parameters, third describes return value. No redundant information. It is appropriately concise for a simple parameter-setting tool.

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?

The tool has a simple interface and an output schema (not shown), so the description need not explain return values in depth. It mentions returning old and new mute state, which is sufficient. However, it omits error handling, prerequisites (e.g., clip must exist), and context about session vs arrangement view. These gaps are minor for a simple mute toggle but could be improved.

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 input schema has 0% parameter description coverage, so the description must compensate. It clearly defines each parameter: 'unit_index: AU index', 'track_index: Track index within the AU', 'clip_index: Clip index', 'mute: True to mute, false to unmute.' This adds essential meaning beyond the schema titles and types.

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 tool's purpose: 'Mute or unmute a clip in the session view.' It specifies the verb (mute/unmute), the resource (clip), and the context (session view). This distinguishes it from sibling tools like set_clip_hue or set_clip_label, which target other clip properties.

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 does not provide explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites, what happens if indices are invalid, or how this tool relates to other mute controls in the DAW. While the purpose is straightforward, some usage context would improve AI decision-making.

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