copy_effects_between_clips

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states 'copy effects between clips' without explaining side effects, whether it modifies source/target clips, or whether it requires specific selection states. The term 'expanded operation' hints at additional behavior but is not elaborated.

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, concise sentence with no redundant wording. It is appropriately sized for a simple operation, though 'expanded operation' is filler, it does not detract from clarity.

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 lacks essential context for a copy operation: it does not mention source/target selection, whether all effects are copied, or what the result is. There is no output schema, and the schema for parameters is empty, so the description carries the burden of explaining behavior, which it fails to fully do.

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?

The tool has 0 parameters, so the baseline of 4 applies. The description does not need to clarify parameter meanings since none are defined, and the schema is empty (allowing 'additionalProperties': {} with no properties listed).

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 states a clear verb ('copy') and resource ('effects') with scope ('between clips'), making the tool's function understandable. However, the phrase 'expanded operation' is vague and does not differentiate this from the similar sibling tool 'copy_effect_values', so it does not fully distinguish.

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 such as 'copy_effect_values' or 'apply_effect'. The description does not mention prerequisites, target selection, or any exclusions, leaving the agent to infer the correct usage context.

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