render_3d

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

Since no annotations are provided, the description bears a high burden, which it meets by disclosing significant behavioral details. It explains the exact file naming convention, the generation of spatial data, provides a list of helper functions (e.g., mat, spot, camera), and specifies dependency environment configurations.

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?

Despite being technically dense and covering three topics (generation, usage, environment), the information is logically grouped and readable. It is efficient in its comprehensive delivery of complex technical instructions.

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 complex 3D rendering tool, the description is very complete. It provides the context for why the hot-spot coordinates are generated (lesson integration), the required scripting format, and the necessary environment setup to run the tool.

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 description coverage is 0%, meaning the description must cover all parameter meaning. The text only elaborates on the purpose of 'name' and 'script' within the context of hot-spot generation, providing virtually no semantic guidance for 'width', 'height', or 'samples'.

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 is highly specific, stating that the tool renders a 3D scene using Blender to generate both an image (assets/<name>.png) and hot-spot coordinates. It clarifies the input requirement of using a bpy Python script.

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?

While it does not explicitly list alternatives, it provides clear workflow instructions, specifically requiring a bpy Python script for scene creation. It also instructs users on prerequisite environment setup, including setting the FLS_BLENDER variable.

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