render_view

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

With no annotations, the description carries the burden and does add useful behavioral detail: deflection controls mesh fineness and implies a speed/quality tradeoff, edges controls overlay rendering, and the return payload is listed. It omits prerequisites (need a shaped-object handle), whether the operation is read-only, and any failure modes, so it is only partially transparent.

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 summary line is front-loaded and the parameter notes are terse and scannable. The return-value list is arguably redundant with a return payload an agent could inspect, but overall there is little waste.

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 6-parameter render tool with no annotations, 0% schema coverage, and no output schema, the description covers the most consequential rendering knobs and the return shape. It still leaves handle, width, and height undocumented in both schema and prose, so it is adequate but not complete.

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 0%, so the description must compensate, and it explains three of six parameters (view values, deflection meaning/units/tradeoff, edges behavior). It leaves width, height, and the required handle unexplained, so the compensation is partial.

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?

States a specific verb (render), resource (view of a shaped object), and output format (PNG). It also enumerates the projection modes, so the agent understands the intent. It does not explicitly distinguish itself from siblings like render_views, section_view, or render_photoreal, which keeps it short of a 5.

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?

There is no statement of when to use this versus render_views (plural/multi-view), section_view (cross-section), or render_photoreal (photorealistic output). The agent must infer the distinction from the view enum alone. No prerequisites (e.g., a valid shape handle must exist) are given.

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