fusion_screenshot

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

The description discloses key behavior: it saves a screenshot of the current viewport and the output format (PNG). However, with no annotations, it carries the full burden and does not mention file overwrite behavior, whether an active Fusion document is required, or if any side effects occur. It is adequate for a simple tool but has gaps in disclosure.

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 entire description is one front-loaded sentence with no redundancy. Every word adds meaning, and the structure places the verb and object first for quick scanning. This is exemplary conciseness.

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 tool with one parameter and no output schema, the description covers the essentials. However, in the context of many fusion_* siblings, it could briefly note when to use this vs. export/render tools, or clarify that it captures the current viewport state. It is complete enough for a simple use case but leaves some contextual gaps.

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 clarify the parameter. It adds value by specifying 'file_path' as the destination and implying PNG format. Yet it does not mention whether the extension must be explicit, path restrictions, or default behaviors. It compensates partially for the schema's minimal string type, scoring a middle 3.

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 'Save a screenshot of the current Fusion viewport to file_path (PNG)' uses a specific verb (save) and resource (screenshot of current viewport), clearly distinguishing it from sibling tools like render_orthographic_views. The scope ('current Fusion viewport') is precise and informative.

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 explicit guidance is given on when to use this tool versus alternatives, nor are there any exclusions or prerequisites (e.g., 'use this instead of export_stl when you need a raster image'). The intended use case must be inferred entirely from the verb and context, which is only minimally sufficient.

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