Create / Update Take

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

With no annotations, the description must carry the behavioral burden, and it does: it reveals the internal operation composition, the checked-by-default batch-render behavior, and the take-handle return value. It does not cover what happens when a duplicate name exists and update_if_exists is false, but the schema parameter description partially fills in that gap.

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 tight sentences deliver the core capability, default behavior, return value, and a recommended use case without filler. The primary capability is front-loaded before secondary details, and every clause earns its place.

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?

The description covers the essential call semantics, the checked default, and the returned handle, which matters because there is no output schema. The main gaps are duplicate-name behavior when update_if_exists is false and any prerequisites for parent/camera/render_data, but the comprehensive per-parameter schema descriptions prevent these from being major omissions.

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 100%, so the schema already documents all nine parameters and earns a baseline 3. The description adds some semantic value by connecting camera/render_data/checked to the SetCamera/SetRenderData/SetChecked operations and explaining checked's batch-render effect, but it is not required to compensate for missing schema info.

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 a precise verb-resource pair — 'Create or update a Take' — and lists the exact bundled operations (AddTake + SetCamera + SetRenderData + SetChecked), making it clearly distinct from single-purpose siblings like take_override or create_render_data. It also explains the checked default and the returned handle, further specifying the tool's uniqueness.

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 phrase 'ideal for building per-shot take stacks programmatically' gives a clear use context, and the checked-by-default explanation tells when to pass checked:false. It does not explicitly name alternative tools or state when not to use this tool, so it stops short of a 5.

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