Remove Keyframe Range

remove_keyframe_range
Destructive

Remove all keyframes within a specified time range from an effect property. Enter the clip's node ID, effect name, property name, and start/end seconds to clear animation data in that interval.

TDQS

A4/5.0
Behavior4/5

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

Annotations already flag destructiveHint=true, and the description adds the important scope of what is destroyed: all keyframes in the given time range, not the property or the clip. It does not discuss edge cases such as empty ranges or invalid properties, but given the annotations, this is acceptable.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence with no filler. It front-loads the verb and resource, states the scope ('all keyframes in a time range'), and avoids repeating schema details or annotations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple, well-specified operation, the description plus schema and annotations cover the essential information: what is removed, which parameters are required, and that it is destructive. It stops short of being fully complete because it does not mention range boundary semantics (inclusive/exclusive) or navigate the agent toward the single-keyframe sibling.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameters are already well documented. The description adds no param-specific meaning beyond reinforcing that 'time range' maps to start_seconds/end_seconds and 'effect property' maps to effect_name/property_name, which the schema already conveys.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Remove') and states the exact target ('all keyframes in a time range from an effect property'). This clearly distinguishes it from the sibling remove_keyframe, which presumably targets a single keyframe, and from add_keyframe/get_keyframes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is implied by the time-range scope: call this when removing a span of keyframes rather than one. However, the description gives no explicit guidance about when not to use it or which sibling alternative (e.g., remove_keyframe) would be appropriate for a single keyframe.

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