apply_easy_ease

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

With no annotations provided, the description must fully disclose behavioral traits. It does not state whether the operation is reversible, if it modifies the property in-place, or if it affects only selected keyframes. The tool is a mutator, but no warnings about idempotency or side effects are given.

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 extremely concise at 4 words. While it lacks detail, it is front-loaded and free of filler. It could be expanded slightly to include key parameter hints without losing efficiency.

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 7 parameters and no output schema, the description is insufficient. The tool has a moderately complex input schema (layer selection via name/index, optional keyframe index, enum type) but the description explains none of this. The agent lacks information to correctly invoke the tool without diving into the schema.

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 only 14%, meaning most parameters lack descriptions in the schema itself. The main description adds no parameter details—e.g., what 'type' enum values mean, how compId vs compName interact, or how layerName vs layerIndex disambiguate. This forces agents to guess or default.

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 'Apply easy ease to keyframes' clearly states the action (apply) and the resource (easy ease to keyframes). It is specific enough to distinguish from many sibling tools like set_keyframe, set_temporal_ease, and offset_keyframes. However, it could be slightly more explicit about whether it operates on a single keyframe or all keyframes of a property.

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?

No guidance is provided on when to use this tool versus alternatives like set_temporal_ease, scale_keyframe_timing, or set_keyframe_advanced. The description does not mention prerequisites (e.g., keyframes must already exist or the property must be animatable) or situations where this tool should be avoided.

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