live12_scene_fire

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

No annotations are present, so the description carries the full behavioral burden, yet it only states that clip slots are launched. It does not mention that this starts playback, interacts with transport state, may stop other clips, or is subject to launch quantization, all of which are important side effects for a live-performance mutation tool.

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?

A single, front-loaded sentence that states the action and scope with no wasted words. The API method reference is compact and useful for agent grounding.

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 one-parameter tool with a fully documented schema and no output schema, the description covers the core action adequately. However, because there are no annotations, it should disclose more about playback side effects and scene-launch behavior to be fully 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?

Schema description coverage is 100%, so the single 'index' parameter is already documented as a zero-based scene index. The description adds context that the scene contains aligned clip slots but does not clarify index semantics beyond what the schema provides, making the baseline 3 appropriate.

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 names a specific verb ('launches') and resource ('all clip slots aligned in a scene'), and preserves the underlying API method (Scene.fire). This implicitly distinguishes it from live12_clip_fire, which fires a single clip, but it does not name that sibling explicitly.

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?

Usage is implied by 'launches... in a scene': the tool is for triggering a whole scene rather than an individual clip. However, there is no explicit guidance on when to prefer it over live12_clip_fire or how it relates to transport tools, leaving the agent to infer the distinction.

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