mcp_opendaw_set_clip_hue

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

The description states that it 'sets' the hue, implying a mutation, and discloses that it returns 'old and new hue'. However, it lacks details on side effects (e.g., UI update, error handling for invalid indices or out-of-range hue), which would be expected given no annotations.

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 brief and to the point. The first sentence states the purpose, followed by a compact parameter list, and a final sentence on return values. No extraneous 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?

For a simple setter tool with all required parameters and a stated return value (old and new hue), the description is fairly complete. It could mention error conditions or indexing conventions, but given the tool's simplicity, it covers the essential context.

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?

With 0% schema description coverage, the description provides crucial semantics: it explains that unit_index is the 'AU index', track_index is 'Track index within the AU', clip_index is 'Clip index', and hue is 'Color hue 0-360'. This adds significant meaning beyond the schema's bare type definitions.

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 verb 'Set' and the resource 'clip in the session view', with a specific attribute 'color (hue)'. This distinguishes it from sibling tools like set_clip_label or set_clip_mute, which target different 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?

No guidance is provided on when to use this tool versus alternatives (e.g., other set_clip_* tools). The description only explains what it does, not the context or preconditions for its use.

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