select_item

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the selection replaces the current selection, whether it operates on the timeline or project panel, or whether it is safe/read-only versus a mutation of selection state.

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 brief but not concise in a useful way; 'Premiere Pro expanded operation' is filler and 'select item' simply repeats the tool name. It is under-specified rather than economically informative.

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?

With no output schema, no annotations, zero parameters, and a large sibling set of selection tools, the description provides almost no information needed for correct invocation. The agent cannot know what object will be selected or what observable effect the tool will have.

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 input schema has zero parameters and 100% schema description coverage, so there are no parameter semantics for the description to add. Baseline for a zero-parameter tool is 4.

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 simply says 'Premiere Pro expanded operation: select item,' which restates the tool name without adding meaningful scope. It does not specify what kind of item is selected, where selection occurs, or how this differs from selection siblings like select_clips_by_name, set_clip_selection, or select_all_clips.

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 about when to use this tool versus the many other selection-related tools. No context is given for selecting project items, clips, tracks, or other object types.

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