fire_clip

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

With no annotations, the description carries the full burden of disclosure. It does not mention any side effects, such as whether firing a clip stops other clips, respects session automation, or if the clip must be prepared (e.g., assigned to a track slot). Behavioral context is missing.

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 extremely concise (two sentences) and front-loads the main action. No wasted words. However, it could be slightly expanded to include critical context without becoming verbose.

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 a simple two-parameter action tool with no output schema, the description is minimally adequate. It covers the action and parameters but lacks return value information and behavioral notes. For a more complex context, it would be incomplete.

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 explain parameters. It provides basic definitions: 'track_index' as index of track, 'clip_index' as index of clip slot. This is helpful but minimal—no details on zero-based indexing, valid ranges, or what happens with invalid indices.

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 'Start playing a clip.' This is a specific verb+resource pair that distinguishes it from siblings like 'stop_clip' (stops a clip) and 'create_clip' (creates a clip). The purpose is 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?

No guidance is provided on when to use this tool versus alternatives such as 'start_playback' (global playback) or 'fire_scene' (fires a scene). There is no mention of prerequisites, context (session vs arrangement), or when not to use it.

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