creator_play_animation

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

With no annotations, the description carries the burden of behavioral disclosure. It reveals one important nuance: omitting the name plays the current clip. However, it does not indicate whether playback is asynchronous, what happens on error, or whether it affects ongoing playback, leaving gaps in full transparency.

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, front-loaded sentence of 11 words. It states the action and the key conditional behavior without any extraneous information, exemplifying conciseness and clear structure.

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 two optional parameters and no output schema, the description covers the core purpose and a key behavioral detail. However, it does not address potential errors, playback state, or the workflow with creator_set_animation, leaving the description minimally complete but not comprehensive.

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 provides descriptions for both parameters (100% coverage), so the baseline is 3. The description adds value beyond the schema by explaining the semantic meaning of omitting the name parameter, connecting it to the 'current clip' concept. This enriches parameter understanding without redundancy.

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 function with the specific verb 'play' and resource 'animation', and it distinguishes itself from sibling tools like pause/stop/seek by describing the optional name parameter and fallback to the current clip. This makes the purpose explicit and unambiguous.

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 when to use the tool (to start playback) but does not explicitly mention alternatives or provide exclusion criteria. It hints at the relationship between the name parameter and the current clip, offering some usage context, but lacks direct guidance on when to use this instead of set_animation or pause.

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