add_light_layer

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

No annotations are supplied, and the description fails to disclose any behavioral traits such as whether this adds a 3D light source, how it interacts with existing layers, or any side effects. The agent has zero insight into the tool's impact.

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 only four words, but it is under-specifying rather than concise. It squanders the opportunity to pack meaningful info into a short statement, offering no value beyond the name.

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?

With 6 parameters, no output schema, no annotations, and no context about behavior or usage, this description is entirely insufficient for an agent to select or invoke the tool correctly. Critical details are missing.

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 0%, yet the description adds no meaning to any of the 6 parameters (name, type, color, compId, compName, intensity). The agent cannot infer correct values or constraints from this description.

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?

Description restates the tool name as 'Add a light layer' without adding any distinguishing context. Among many sibling add_*_layer tools (solid, text, shape, camera, etc.), this provides no differentiation, making it a tautology.

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 light layer tool versus other layer types or when to avoid it. The description does not mention scenes requiring 3D lighting or prerequisites like a camera layer.

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