set_clip_properties

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

No annotations are provided, so the description carries the burden. It discloses the partial-update behavior and includes parameter ranges (e.g., pitch_coarse -48 to 48). It doesn't mention permissions or side effects, but for a setter this is reasonable coverage.

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 a single introductory sentence followed by a clean bullet list of parameters. Every line earns its place with no fluff or redundancy. It is front-loaded with the core purpose.

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?

With 13 parameters and no annotations, the description does a good job covering all parameter semantics and the key partial-update behavior. It doesn't address return values or clip-type applicability, but an output schema exists to cover return structure, making this adequate if slightly incomplete.

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%, but the description compensates fully by explaining every parameter including units, ranges, and context (e.g., 'gain: Gain value for audio clips', 'pitch_coarse: Coarse pitch transposition in semitones'). This adds significant meaning beyond the schema's bare titles and types.

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 multiple clip properties in a single call' with a specific verb and resource. It distinguishes itself from single-property setters like set_clip_name and set_clip_loop by emphasizing the batch capability.

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?

It explicitly states that only provided properties are changed and omitted ones are left unchanged, giving clear usage context. It doesn't name alternatives directly but implies use when multiple properties need updating at once, which is adequate guidance.

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