fire_clip

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

No annotations provided, so the description must bear the full burden. It only states 'Start playing a clip' without explaining behavior like what happens if the clip is already playing, whether it stops other clips, or any side effects. Minimal disclosure.

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 very concise with no wasted words. It front-loads the purpose. However, the parameter list could be integrated more smoothly.

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 3 parameters (including 'ctx' with no explanation), no output schema, and 0% schema coverage, the description is incomplete. It lacks details on return values, side effects, and the context parameter's role.

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% and the description only lists parameter names without any elaboration. The 'ctx' parameter is completely omitted from the description. Parameter semantics are not enhanced 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 'Start playing a clip' clearly states the action and resource. However, it does not differentiate from sibling tools like fire_scene or start_playback, which have similar purposes. The 'ctx' parameter is also not mentioned in the purpose.

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 vs alternatives such as 'stop_clip', 'fire_scene', or 'start_playback'. No conditions or prerequisites stated.

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