render_preview_2d

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

The description does not disclose behavioral traits beyond the basic action. With no annotations, it fails to mention side effects (e.g., file creation/overwrite), error conditions, or format details. The agent lacks understanding of what happens if no drawing is loaded.

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 extremely short (one sentence) but lacks critical information, making it under-specified rather than optimally concise. It is barely adequate for a simple 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?

Given the presence of an output schema, return values need not be explained. However, the description omits prerequisites (e.g., loaded drawing), known behaviors, and how it differs from sibling tools like 'export_model'. It feels incomplete.

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 only parameter 'output_path' has no description in the schema or the tool description. With 0% schema description coverage, the description should explain the parameter's purpose, but it does not. The default is given but its meaning is unclear.

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 verb 'render' and the resource 'current DXF drawing to PNG', directly indicating what the tool does. It distinguishes from the sibling 'render_preview_3d' by specifying 2D output.

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 is provided on when to use this tool versus alternatives like 'export_model' or 'render_preview_3d'. There is no mention of prerequisites (e.g., a loaded DXF drawing) or context for the tool.

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