mcp_opendaw_set_clip_label

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

With no annotations provided, the description must disclose behavior. It mentions 'Returns success with old and new label' but does not explain side effects, overwriting semantics, error conditions, or index conventions. The mutation side effect is implied by 'Set' but not detailed.

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 compact and front-loaded: a one-sentence purpose, a terse parameter list, and a return note. No filler or redundant content.

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 description provides the essential purpose and parameters, and the output schema covers return values, so it is reasonably complete for a simple setter. However, it lacks guidance on how to resolve indexes or when this tool is appropriate among many similar clip/marker setters.

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%, so the description must compensate. It defines each of the four parameters: unit_index, track_index, clip_index, and label, with brief but meaningful explanations that go beyond the bare schema property names.

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 action: 'Set the label (name) of a clip in the session view', which is a specific verb+resource that differentiates it from sibling tools like set_region_label and set_marker_label.

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 set_region_label or set_clip_properties. The description only gives the action and parameter list, with no mention of indices sourcing or alternative scenarios.

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