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

Annotations only indicate readOnlyHint=false, requiring the description to disclose behavioral traits. The list of actions is provided but without details on side effects, prerequisites, or return values. The description does not explain what each action does beyond its name.

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 bullet list, but it is dense and not well-structured for quick agent parsing. It could be more efficient by grouping related information.

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 complexity (17 parameters, multiple actions, no output schema), the description is incomplete. It does not explain which parameters are required for each action or provide usage examples, leaving the agent with insufficient context.

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 100%, so the base rating is 3. The description adds the list of actions but does not map parameters to specific actions or provide additional meaning beyond the schema descriptions.

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 it controls Unity Animation and Timeline systems and lists the actions, which differentiates it from sibling tools focused on other domains like lighting or physics. However, it could be more specific about the scope.

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 animation/timeline tasks but lacks explicit guidance on when to use this tool versus alternatives or when not to use it. There are no exclusion criteria or context for action selection.

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