mcp_opendaw_set_clip_properties

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

Without annotations, the description discloses key behavioral details: skip values for each parameter (empty string, -1, None) and that it returns updated clip properties. This adds value beyond the schema, though it could mention that it modifies the clip in place.

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 well-structured: purpose sentence, skip conventions, parameter list, and return statement. No unnecessary words.

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 covers purpose, parameter meanings, skip behavior, and return value. It is complete for a compound setter, though it could note that this is an alternative to individual setters or mention that all parameters are required but skippable.

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 coverage is 0%, so the description fully compensates by explaining each parameter's meaning and skip conventions. For example, 'clip_index: Clip index (from list_clips)' and skip values are clearly documented.

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 'Set properties on a clip (session view): label, color, mute, duration' and lists all parameters. It distinguishes from sibling tools by being a compound setter, and the title 'mcp_opendaw_set_clip_properties' aligns with this.

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 usage for setting multiple clip properties at once, but it does not explicitly state when to use this tool versus the individual set_clip_hue, set_clip_label, etc. For example, it could say 'Use this to set multiple properties in one call instead of individual setters.'

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