fire_clip

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

With no annotations, the description carries the behavioral burden, and it does disclose one meaningful trait: playback begins on the next launch-quantization boundary rather than immediately. However, it omits other relevant behavior such as whether the clip must already exist, what happens with an empty slot, or any permission requirements.

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 short sentence, front-loaded with the action and followed by the only non-obvious nuance. No filler or redundancy.

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 two-parameter trigger tool with no output schema this is minimally viable: the action and timing are covered, but parameter meaning and edge cases (missing clip, empty slot) are absent, leaving gaps an agent would need to guess at.

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% and the description says nothing about track_index or slot_index, so neither parameter's meaning (e.g., whether indices are zero-based, or how they map to tracks/scenes) is explained anywhere. The description fails to compensate for the coverage 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?

"Launch a clip" states a specific verb and resource, and the parenthetical clarifies the timing semantics. It is readily distinguishable from fire_scene, stop_track_clips, and create_clip, though it does not explicitly name any sibling.

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 gives no when-to-use or when-not-to-use guidance and never mentions alternatives such as fire_scene or stop_track_clips. An agent must infer that firing is the way to trigger playback from the verb alone.

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