fire_scene

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

No annotations are present, so the description carries the full burden. It states the action but does not disclose behavioral traits such as whether it stops other clips, affects playback state, or requires a valid scene index. For a state-changing tool, more transparency is needed.

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 that front-loads the verb. However, it is so terse that it omits necessary context, such as parameter information. It earns its place but could be slightly expanded without losing efficiency.

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 the tool has one parameter and an output schema exists, the description need not explain returns. However, the description is minimal and does not provide enough context about the action's effect on the session, making it barely adequate.

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 0%, meaning no parameter descriptions in the schema. The description does not mention the required 'scene_index' parameter, leaving its purpose and constraints completely unexplained. This fails to compensate for the schema gap.

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 'Launch' and clearly identifies the resource 'all clips in a scene row'. It distinguishes this tool from siblings like 'fire_clip' (which launches a single clip) and 'create_scene' (which creates a new scene).

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 usage when you want to trigger all clips in a scene simultaneously, but it does not explicitly state when to use this tool versus alternatives like 'fire_clip' or 'play'. No exclusions or when-not-to-use guidance is provided.

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