save_scene

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

No annotations are provided, so the description must carry the full behavioral burden. It only states 'save the scene' without disclosing effects such as whether it overwrites the file if it exists, whether it creates intermediate directories, whether it triggers a render or a ZBrush-like save, or what happens with unsaved documents. It also doesn't mention if the 'scene' is the entire project or just a sub-scene, leaving behavioral uncertainty.

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 brief, consisting of a short sentence plus an argument description. However, it is under-specified rather than concise; the lack of detail is not an efficient use of space, but rather a missed opportunity to convey important context. The structure is adequate but not exemplary, as it doesn't front-load critical information like warnings or side effects.

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 a simple schema (one parameter), the description is not complete because it lacks any mention of the output schema (which exists, indicating there is a return value), any error conditions, or any behavioral expectations. Since it's a mutation-like tool (save operation) with no annotations, the description should cover side effects and potential risks, which it does not. The adjacent sibling 'snapshot_scene' suggests there is a difference between saving and snapshotting, but this is not explained.

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 only one parameter, file_path, with a default of null. The description says 'Optional path to save the scene to', which adds a little context about the parameter's purpose (the path where to save). Since the schema already clearly indicates the parameter is optional and nullable, the description's value is marginal. With schema description coverage at 0%, the description does add some meaning but not much beyond what the schema's field name suggests.

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 tool saves the current Cinema 4D scene, which is a specific action on a clear resource. It doesn't explicitly distinguish from the sibling tool 'load_scene' or 'snapshot_scene', but the verb 'save' is distinct enough that the purpose is clear without being confused with loading or snapshotting.

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 does not provide any guidance on when to use this tool versus alternatives like 'load_scene' or 'snapshot_scene'. There is no mention of prerequisites (e.g., whether a scene must be loaded first), no mention of typical usage scenarios, and no indication of why one would choose this over a similar tool. The lack of usage context is a significant gap for an agent determining the right tool.

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