copy_effect_values

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

With no annotations and a generic description, there is no disclosure of side effects, permissions, or return behavior. The phrase 'expanded operation' adds no transparency about what the tool actually does.

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 (one sentence) but lacks structure and substance. It is so brief that it doesn't convey meaningful information, making it ineffective despite its brevity.

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 fails to provide necessary context about what 'effect values' are, the source and target of the copy, or any related workflow. It is incomplete for an operation that likely requires specific parameters and understanding.

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?

Although the schema shows no defined parameters, the description does not clarify that the tool accepts no arguments or explain what fields might be expected. Since the schema is permissive, the description should compensate but fails to provide any parameter semantics.

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 'Premiere Pro expanded operation: copy effect values' is extremely vague, providing no specific action or context. It does not distinguish from sibling tools like copy_effects_between_clips, making the purpose unclear.

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 given on when to use this tool versus alternatives. There is no indication of prerequisites, typical scenarios, or steps, leaving the agent without direction.

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