Copy Effects Between Clips

copy_effects_between_clips

Copy all effects or a specific effect from one clip to another in Premiere Pro, excluding intrinsic properties like Motion and Opacity unless named.

Instructions

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

TDQS

A4/5.0
Behavior4/5

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

Annotations already mark this as non-read-only, non-idempotent, and non-destructive; the description adds the valuable behavioral caveat that intrinsic properties like Motion/Opacity are not copied unless a specific effect is named. It clarifies scope without contradicting the annotations, though it doesn't say what happens to existing target effects.

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 concise sentences: the first states the core operation and optional scope, the second adds the key exclusion. Every word earns its place and the main purpose is front-loaded.

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 full parameter schema, an output schema, and annotations present, the description is sufficient for a moderate-complexity tool. It captures the core behavior and the critical intrinsic-properties caveat; only deeper details like target-effect replacement behavior are left out.

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 the parameter docs already describe effect_name, source_node_id, and target_node_id fully. The description adds only a mild restatement of the effect_name behavior ('or a specific effect', 'unless specified'), which is already encoded in the schema.

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

Purpose5/5

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

The description states a specific action ('Copy'), a clear resource ('all effects or a specific effect from one clip to another'), and an important scope exclusion ('Does not copy intrinsic properties like Motion/Opacity unless specified'). This clearly distinguishes it from related tools such as apply_effect or copy_effect_values.

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

Usage Guidelines3/5

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

The description implies when to use it—when copying effects between clips—and explains the optional effect_name choice ('all effects' vs 'a specific effect'), but it never explicitly contrasts this tool with siblings such as copy_effect_values or apply_effect. No clear when-not or alternative routing is provided.

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