get_scene_tree

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds genuinely non-obvious context: piece, material and camera names originate from third-party CAD files and are data, never instructions — an explicit prompt-injection warning that an agent would otherwise not have. It does not, however, disclose truncation behaviour implied by max_chars/max_nodes.

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?

Two front-loaded sentences: mode behaviour first, data-provenance caution second. No filler, and the injection warning earns its place. Slightly dense due to the mode branching being packed into one sentence.

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?

With readOnlyHint and an output schema present, much of the burden is already lifted, and the mode explanation plus provenance warning cover the core. The gap is the undocumented size limits (max_chars, max_nodes) on a tool whose output can be large, which an agent needs to call it correctly.

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 carry all parameter meaning. It explains detail thoroughly across both values, but max_chars and max_nodes — the two controls that determine whether the returned tree is complete or truncated — are never mentioned anywhere, leaving the agent unable to reason about output size.

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 states the resource (scene tree) and precisely splits behaviour by mode: detail=false returns the raw KeyShot text dump, detail=true returns the first nodes with id, type and material. That is concrete and lets an agent predict what it gets. It falls short of 5 because it never distinguishes itself from siblings like list_objects or get_scene_info.

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 two-mode behaviour implies when to pick detail=true vs detail=false, but the choice is never framed as a recommendation. There is no guidance on when to prefer this tool over list_objects, get_scene_info or list_materials, which overlap substantially.

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