modify_layer

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

No annotations are provided, and the description gives no details about side effects, permissions, or the nature of the modification. It simply states that layer properties are modified without any behavioral disclosure.

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 brief and contains no fluff or unnecessary words. It is well-structured as a single clear phrase, though its brevity borders on being too minimal.

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's complexity (20 parameters, no schema descriptions, no output schema), the description is severely incomplete. It fails to provide any context about the purpose, usage, or effects, making it nearly unusable for an agent.

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 input schema has 20 parameters but no descriptions, and the description does not explain any of them. Parameters like 'shy', 'is3D', and 'blendMode' are left completely ambiguous, which is critical given the lack of schema-level descriptions.

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 'Modify layer properties' specifies a clear verb and resource, and it is distinct from the sibling tool 'modify_composition'. It does not specify which layer or which properties, but it is still unambiguous as a general layer modifier.

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?

The description provides no guidance on when to use this tool versus other layer-specific tools (e.g., set_keyframe, apply_effect). There is no mention of prerequisites, alternatives, or conditions for use.

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