set_scene_property

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

With no annotations, the description carries the full burden for behavioral traits. It mentions returning a confirmation dict but omits side effects (e.g., whether setting frame_current affects animation), required permissions, or constraints (e.g., frame_start < frame_end). The value parameter's type is vaguely described as 'depends on property'.

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 structured with Args and Returns sections, which aids readability. However, the first sentence repeats the property list that is already in the Args section, causing slight redundancy. It is generally concise but could be more efficient.

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?

Despite having an output schema indication, the description lacks important context such as constraints on property values (e.g., frame_start must be less than frame_end), potential errors, or preprocessing steps. The output schema is mentioned but not detailed. The tool's complexity is low, but key operational context is 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 coverage is 0%, so the description must add meaning. It lists allowed values for 'property' (enumeration) and describes 'value' as type-dependent. This adds some semantics beyond the schema but does not specify types for each property, leaving ambiguity. Baseline 3 is appropriate.

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 'Set a scene property' and lists specific properties (e.g., frame_start, render_engine), which distinguishes it from sibling tools like set_bone_property or set_camera_property that operate on different objects. The verb and resource are precise.

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 on when to use this tool versus alternatives. The description only lists what it does, without explaining contexts (e.g., before rendering, after setting other properties) or excluding inappropriate uses. An agent must infer from the name alone.

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