mcp_opendaw_set_clip_label

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

The description states it sets the label and returns old/new label, but with no annotations, it fails to disclose whether changes are destructive, if there are length limits, or any side effects. This is minimal for a mutation tool.

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 concise and front-loaded with the purpose. It lists parameters in a clear, scannable format without unnecessary words. Every sentence adds value.

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 simple with 4 required parameters and an output schema. The description covers the return value (old/new label). It is sufficient for basic usage, though it could mention potential constraints or failure modes.

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?

Despite 0% schema coverage, the description explains each parameter's meaning ('AU index', 'Track index within the AU', etc.), providing essential context beyond the raw schema. This compensates well for the missing schema descriptions.

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), resource (label of a clip), and context (session view). It distinguishes from sibling tools like set_clip_hue or set_clip_mute by specifying the exact attribute being modified.

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 like set_clip_properties or other clip mutation tools. There is no mention of prerequisites, exclusions, or typical use cases.

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