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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states that the tool selects the clip, but omits what happens if the name is invalid, whether it replaces the current selection, or whether it affects ongoing playback, leaving the operation's behavior largely opaque.

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 sentence with no filler, front-loading the key action and purpose. Every word earns its place.

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 single-parameter selection tool with no output schema, the description is functional but thin: it omits error behavior, return value, and how the selection affects subsequent animation operations. Given the low complexity, it is adequate but not complete.

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?

The schema already documents the 'name' parameter as 'Animation name', and the description's phrase 'the animation clip' largely restates this. With 100% schema coverage, the description adds minimal semantic value beyond the schema, but the baseline of 3 applies.

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 ('Select') with a clear resource ('the animation clip') and scope ('to edit or play'), distinguishing it from sibling tools like play_animation or seek_animation. It unambiguously indicates this is a state-setting operation for the current animation clip.

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 phrase 'to edit or play' implies when this tool is used: before editing or playing an animation. It does not explicitly name alternatives or when-not-to-use scenarios, but the purpose is clear enough given the sibling list.

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