mcp_opendaw_create_value_clip

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

With no annotations provided, the description carries the transparency burden. It does disclose that the clip is created empty ('an empty ValueEventCollectionBox') and that it operates on the specified automation track. However, it does not mention potential side effects such as overwriting an existing clip at the given clip_index, failure behavior on invalid indices, or whether the operation is reversible. This is a moderate level of disclosure.

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 well-structured: a one-sentence purpose, an implementation note, a four-item parameter list, and a one-line return note. Every line earns its place, with no repetition of schema details and no filler.

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 is a simple creation operation, and the description covers the core behavior, parameters, and return value. The output schema exists (per context) so the vague 'Returns clip creation details' is acceptable. Missing context includes prerequisites (did the automation track exist?) and behavior when the clip slot is already occupied, but these are not critical for a basic creation tool.

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 schema provides zero description coverage, but the description compensates fully by listing each parameter with a brief explanation: unit_index (audio unit), track_index (with the special -1 value), name (label), and clip_index (0-based). This adds meaning well beyond the bare schema property names and also teaches the indexing conventions.

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 opens with a specific verb+object+context: 'Create a value clip (automation clip) on an automation track in session view.' This clearly distinguishes this tool from siblings like create_audio_clip or create_note_clip, and the reference to ProjectApi.createValueClip further cements its purpose.

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 implies the use case—creating an automation clip on a Value-type track—but does not explicitly state when to use this tool over alternatives (e.g., create_automation_event or add_automation) or when not to use it. No exclusions or alternative tool mentions are provided.

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