fire_clip

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not state whether playback transport must be active, whether firing a clip stops or overlaps others on the same track, or any side effects — only that a telemetry parameter exists. The disclosed behavior is thin for a tool that triggers an audible action.

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 tight — a one-sentence purpose followed by a compact parameter list with no filler. Purpose is front-loaded and every line 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?

An output schema exists, so return values need no elaboration. The two required indices and the telemetry param are covered, but the missing distinction from start_playback and the unstated runtime precondition (whether transport must be running) leave the agent under-informed for a tool with audible side effects.

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 0%, so the description must compensate, and it does: it explains what track_index and clip_index refer to ('the track containing the clip' and 'the clip slot containing the clip') and identifies user_prompt as telemetry. This adds meaning beyond the bare schema titles.

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?

'Start playing a clip' states a specific verb and resource clearly. However, it does not differentiate from the sibling 'start_playback', which also initiates audio, leaving an agent to guess which one fires a single clip versus the whole transport.

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?

There is no guidance on when to use this tool versus alternatives. Notably, 'start_playback' and 'stop_clip' are siblings, and the description gives no hint about whether transport must already be running for fire_clip to have an effect, or how it relates to those tools.

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