set_eevee_light_path

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

No annotations are provided. The description states it sets intensity controls and returns a dict with current values. For a setter tool, this is minimally adequate, but it does not disclose potential side effects or whether parameters are persistent. No contradictions with absent annotations.

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: three sentences plus a clean list of args and return. It is front-loaded with the main purpose, and every sentence adds value. No redundant or missing parts.

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?

For a simple tool with three optional parameters and an output schema, the description covers purpose, usage condition, parameter meanings, and return. It is nearly complete, but missing explicit handling of null parameters could slightly reduce utility.

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 schema has 0% description coverage. The description compensates by explaining each parameter's function (diffuse, glossy, transmission) and valid range (0.0-10.0). However, it does not clarify the meaning of null (likely no change) or provide examples.

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 verb 'set', the resource 'EEVEE light path intensity controls', and the context (Blender 5.1+, only for BLENDER_EEVEE engine). It distinguishes from sibling tools like set_render_engine or set_shadow_settings by focusing on light bounce intensities.

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 explicitly says 'Only applies when render engine is BLENDER_EEVEE', providing clear usage context. It implies not to use with other engines but does not mention alternative tools or prerequisites like setting the render engine first.

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