createSolidLayer

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Create a solid color layer' implies a mutation that adds a new layer to the project, but the description does not mention side effects (e.g., changes to the active composition or selection), permissions required, reversibility, or whether the layer is returned.

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?

A single, front-loaded sentence with no wasted words. The purpose is stated immediately and clearly, making the description appropriately sized for a straightforward creation tool.

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 that the tool is a mutation with no annotations and no output schema, the description is too sparse. It does not explain what happens upon success (e.g., whether a new layer is selected or returned) or any practical constraints (e.g., whether a composition must be active), leaving the agent uncertain about the full behavior.

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?

Schema description coverage is 100%, so the input schema already documents all six parameters, including defaults for name, width, height, and duration. The description adds no parameter-level details beyond what the schema provides, which is the baseline for full coverage.

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?

States a specific verb (Create), resource (solid color layer), and scope (in the composition). This is clearly distinguishable from siblings like createTextLayer, create3DLayer, createCamera, and createLight, which create different layer types.

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?

Usage is implied by the purpose: use this tool to add a solid color layer to a composition. However, there is no explicit guidance on when to choose this over alternatives (e.g., create3DLayer, createNullObject) or any prerequisites or exclusions.

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