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

With no annotations provided, the description carries the full disclosure burden but offers minimal behavioral context. It does not explain return format, whether this queries the editor or a running game instance, or what the 'compatibility' designation means operationally.

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 compact and front-loaded with the primary action. The '(Compatibility tool)' tag is terse and potentially vague, but the text contains no redundant sentences or fluff.

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 two undocumented parameters and no output schema, the description is insufficient. It fails to compensate for the schema's lack of descriptions or explain the compatibility context, leaving significant gaps in the agent's understanding.

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%, yet the description adds no meaning for 'timeoutMs' or 'autoConnect'. The agent has no guidance on what connection timeout refers to or what auto-connecting entails, leaving critical parameters effectively undocumented.

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 uses a specific verb ('List') and resource ('animations in AnimationPlayer'), making the core purpose clear. However, it does not explicitly differentiate from sibling 'get_animation_info' (which likely retrieves detailed data for a single animation vs. enumerating all).

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 '(Compatibility tool)' parenthetical hints at special usage constraints but fails to explain when to use this tool versus alternatives, when not to use it, or what 'compatibility' implies for the workflow.

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