set_target_track

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

With no annotations, the description carries full responsibility for disclosing behavior. It only states the action without detailing side effects, state changes, or dependencies (e.g., whether it modifies the active sequence's targeted tracks, if it requires a specific sequence to be loaded, or if it affects clip insertion). This is a significant gap for a mutating operation.

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 one sentence with no wasted words, so it is concise. However, it is under-specified; it lacks the detail needed to be truly useful. Conciseness is more than brevity; it should pack information efficiently, and this sentence provides only a nominal purpose.

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's apparent simplicity, the description is still incomplete. It does not explain what 'target track' refers to (e.g., audio/video, specific index), how the tool selects the target, or any effects on subsequent operations. With no annotations, output schema, or parameter explanations, the description fails to provide enough context for an agent to use it correctly.

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?

The tool has 0 parameters, and schema coverage is 100% (trivially). Per rubric, baseline for high coverage is 3. The description does not need to explain parameters since none exist, but it also does not add any context about what the tool operates on, relying entirely on implicit understanding of 'target track'. Thus it meets baseline but adds no extra value.

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 states a specific action: 'set target track' on Premiere Pro, which is a verb+resource. However, it doesn't elaborate on what 'target track' means in the context of Premiere Pro, nor does it distinguish this from the sibling get_target_tracks other than inversion. It's clear but lacks specific scope.

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 usage guidance is provided. There is no mention of when to use this tool, what prerequisites exist (e.g., an active sequence or selected track), or how it differs from alternatives like get_target_tracks or set_all_tracks_targeted. The description is too minimal to offer any context for selection.

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