set_frame_blend

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It merely states the operation without describing side effects, requirements, or expected results. There is no information about what 'frame blend' does or what changes it makes to the project, which is a serious 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?

The description is only one sentence and contains no redundant words, but it is severely under-specified. While conciseness is a virtue, this is not 'appropriately sized' because it fails to provide essential information, making it more a placeholder than a useful description.

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 no annotations, no output schema, and a minimal description, the tool is almost entirely unexplained. Even a simple setter action like this should clarify what frame blend means, how it is applied, and what the expected outcome is. The description is far too sparse for an agent to use 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?

The input schema is an empty object with zero parameters, so there is nothing for the description to add. The baseline for zero parameters is 4, and the description correctly omits any parameter details since none exist.

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 says 'set frame blend' which names a specific operation, but it does not explain what frame blend is or how it differs from similar operations like set_time_interpolation or set_blend_mode. Without context, the purpose is only marginally clearer than the tool name itself.

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 guidance on when to use this tool, when not to, or what alternatives exist. The description provides no contextual hints about typical use cases or prerequisites, making it impossible for an agent to decide between this and sibling tools.

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