generate_pet_bowl

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

With no annotations, the description must carry behavioral disclosure. It usefully states that the tool opens an interactive 3D stage, may attach a hosted browser stage link, auto-decimates oversized meshes, and has a 3-per-month free-tier limit. However, it does not explain generation latency, persistence of the result, error behavior, or what happens when the quota is exhausted.

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 purpose is front-loaded, but the description is bloated with promotional upgrade text and repeats the inline 3D stage information in a separate section. The MAKE DOORS paragraph is also confusing and not clearly tied to invoking this specific 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?

For a 12-parameter generation tool with no annotations and no output schema, the description leaves important gaps: it does not describe parameters, return artifacts beyond the stage/preview, or whether the result is saved as a design. It provides useful stage and quota context, but not enough for an agent to call the tool confidently.

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 baseline is 3 even though the description adds no parameter meaning. The schema only supplies defaults for parameters such as size, bottom, wall_mm, material, and photo_mask, and the description does not clarify their valid values or interactions.

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 first sentence states a specific verb and resource: generate a tapered pet bowl optimized for FDM printing. This clearly distinguishes it from sibling product generators such as generate_pen_cup, generate_ashtray, and generate_coaster.

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 gives some usage context through the free-tier quota and the note that design_session is not installed, but it does not explicitly say when to choose generate_pet_bowl over generic tools like compile_scad, generate_model, or design_session. The MAKE DOORS paragraph is more server-level guidance than a clear routing rule for this tool.

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