game_play_animation

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

The description lists the possible actions (play, stop, pause, get_list), which conveys both read and write behaviors. However, it does not disclose any side effects, permissions required, or safety implications. Given no annotations, more detail would be beneficial.

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 concise sentence of 12 words, efficiently conveying the tool's purpose and actions. It is front-loaded and contains no filler.

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 simple tool with three parameters and no output schema, the description covers the main usage. However, it does not describe the return format for actions like 'get_list', which could be important for an agent to process results.

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 coverage is 100%, so the schema already describes all parameters well. The description adds no additional meaning beyond enumerating the actions; it does not clarify format or constraints beyond what the schema provides.

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 an AnimationPlayer node with specific actions (play, stop, pause, list), which gives a good sense of purpose. However, it does not explicitly differentiate from similar sibling tools like 'game_animation_control' or 'game_animation_tree', so it is not maximally distinctive.

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 on when to use this tool versus alternatives or any prerequisites. The description only states what it does, without any context about when it is appropriate or when to avoid it. This leaves the agent without decision support for tool selection.

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