animate_color_fx

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does reveal that the effect is time-based and implemented via Fusion, but it does not explain whether existing color grades are overwritten, whether repeated calls stack, what the frame range semantics are, or whether the operation is reversible. For a mutating tool with zero annotation coverage, this is a notable 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 a single front-loaded sentence with no filler. It opens with the core verb and resource, then adds specific effect details and the Fusion mechanism in a compact parenthetical.

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?

For a tool with 10 parameters, no annotations, and no parameter-level schema descriptions, the description is too sparse to be complete. It does not explain frame-range behavior, how saturation/tint_strength interact with the animation, or what happens to existing clip color settings. The presence of an output schema covers return values, but not these usage-critical details.

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 0%, so the description must compensate, but it only implicitly maps to rainbow/flicker parameters and leaves item_id, start_frame, end_frame, saturation, tint_strength, and the numeric tuning parameters unexplained. Ten parameters exist, and the description adds meaning for only a couple of them.

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 specific action ('Animate dynamic color effects') on a specific resource ('a clip') with specific techniques ('rainbow hue rotation and subtle organic luminance flicker') and the mechanism ('via Fusion'). This clearly distinguishes it from siblings like animate_zoom, keyframe_clip_saturation, and set_clip_color.

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 description implies this tool is for time-based color animation via Fusion, which gives some context, but it never explicitly states when to choose this over alternatives such as set_clip_color or keyframe_clip_saturation. There are no exclusions or conditions provided.

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