Copy Effects Between Clips

copy_effects_between_clips

Copy all effects or one specific effect from a source clip to a target clip. Intrinsic properties like Motion and Opacity are not copied unless specified.

Instructions

Copy all effects (or a specific effect) from one clip to another. Does not copy intrinsic properties like Motion/Opacity unless specified.

TDQS

A3.6/5.0
Behavior4/5

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

Annotations declare a non-read-only, non-destructive, non-idempotent mutation, so safety is largely covered. The description adds a genuinely non-obvious behavioral constraint: intrinsic properties such as Motion/Opacity are excluded unless specified. It stops short of saying whether existing target effects are replaced or merged, which would be the remaining high-value detail.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the core action and followed by the one meaningful caveat. No filler or restated title content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need not be explained, and annotations carry the safety profile; the description covers the action and the intrinsic-property exclusion. The only real gap is the replace-vs-merge semantics on the target clip, which matters for a non-idempotent mutation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all three parameters are already documented in the input schema, including the 'copies all non-intrinsic effects if omitted' behavior for effect_name. The description adds no format or syntax detail beyond that, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Copy all effects (or a specific effect) from one clip to another') and clarifies scope with the intrinsic-property caveat. It does not name the nearest siblings (copy_effect_values, paste_clip_attributes, batch_apply_effect), so an agent still has to infer differentiation, which keeps it below 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies that omitting effect_name copies everything, but it gives no when-to-use guidance against close alternatives like copy_effect_values or paste_clip_attributes, and no prerequisites (e.g. both clips must exist in the same sequence). Usage context is left entirely to inference.

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