insert_keyframe

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

The annotations already indicate destructiveHint=true and readOnlyHint=false, so the mutation nature is known. However, the description adds no further behavioral details, such as whether existing keyframes are overwritten or how interpolation is affected.

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 a single, front-loaded sentence with no superfluous words. It effectively communicates the core function in one line.

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 tool's simplicity and the presence of an output schema, the description is minimally sufficient. However, it omits the object_name context and does not clarify insertion behavior, leaving some ambiguity for a destructive operation.

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 schema has 0% description coverage, so the description must compensate. It mentions 'location/rotation_euler/scale/...' which offers examples for the property parameter, but it does not explain the frame or object_name parameters or acceptable values.

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 'Sisipkan keyframe (location/rotation_euler/scale/...) pada sebuah frame' clearly conveys an insertion operation for keyframes on a frame. It identifies the action and resource, though it does not explicitly distinguish itself from animation-related siblings like set_keyframe_interpolation.

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 information about when to use this tool versus alternatives. The description only states the action without context on prerequisites or when to prefer it over other animation tools.

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