copy_layers_between_sprites

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

No annotations are provided, so the description must fully disclose behavior. It mentions replace and create_missing_frames, but lacks details on prerequisites (files must exist, target must have matching layers), error handling, or whether operation is destructive. For a tool with no annotations, this is insufficient.

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 extremely concise: one sentence plus bullet-point parameter list. Every word adds value, no fluff. Front-loaded with the purpose, making it efficient for quick understanding.

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?

Given the tool has 5 parameters, no output schema, and no annotations, the description covers basic operation and parameter meanings. However, it lacks important context like return value, error cases, and prerequisites (e.g., source and target files must be open). Completeness is adequate but not thorough.

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?

With 0% schema description coverage, the description must compensate. It provides brief but functional explanations for each parameter (e.g., 'replace: Overwrite existing cels in target layers'). However, it omits constraints like file path format or layer existence requirements, so it only partially compensates.

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 the tool copies layers by name from a source sprite to a target sprite. The verb 'copy' and resource 'layers' are specific, and the target/source distinction differentiates it from siblings like duplicate_layer (same sprite) or copy_sprite (entire sprite).

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 like copy_sprite or duplicate_layer. The description lacks exclusions or context that would help an agent decide between similar operations.

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