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

No annotations provided; the description carries full burden. It mentions flicker prevention and shared palette but does not disclose whether the process is destructive, alters input files, or requires specific access rights. Some behavioral aspects are implied (e.g., output creation) but not explicitly stated.

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 concise with a one-sentence purpose followed by a parameter list. It is front-loaded with the main action. No extraneous words, but the structure could be improved with section headers or clearer grouping.

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 complexity (9 parameters, 4 required, no output schema), the description is incomplete. It does not explain return values, error conditions, or side effects. The overall function is clear, but practical context for successful invocation is lacking.

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 parameter list in the description adds value beyond the schema. It gives brief Korean descriptions for each parameter (e.g., 'frame1: second frame path (same character, different pose)' and specifies outline_style values as 'selout' or 'solid'). However, descriptions are terse and not all parameters are explained in depth.

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 clearly states the tool's purpose: pixelating two-frame animations with a common scale and shared OKLab k-means palette to prevent flickering. This specificity distinguishes it from sibling tools like pixelize (single frame) and batch_pixelize (batch).

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 usage for two-frame animations to avoid flickering but does not explicitly state when not to use it or mention alternatives. Siblings such as pixelize and batch_pixelize provide related but distinct functionality, but no explicit guidance is given.

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