set_item_in_out

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

With no annotations provided, the description carries the full burden of disclosing behavior. It only states 'expanded operation' with no mention of effects, side effects, required permissions, or output. Nothing beyond the raw action is revealed.

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 short sentence, but it is under-specified rather than concise. It omits essential context and does not earn its brevity because it lacks substantive information.

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 complexity (setting in/out points on an item in Premiere Pro) and the absence of annotations, output schema, or documented parameters, the description is severely incomplete. It provides no guidance on input, expected behavior, or relation to surrounding tools.

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 is an empty object with additionalProperties allowed, yet no properties are documented. The description provides no parameter details, leaving the agent with no idea how to specify the item or in/out values. Schema coverage is technically 100% but only because there are zero defined parameters, so the description fails to compensate.

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 verb ('set') and a resource ('item in out'), implying it sets in/out points on an item, but 'expanded operation' adds no clarity and it does not distinguish itself from siblings like set_sequence_in_out_points or set_source_in_out. The purpose is only vaguely inferred, not clearly articulated.

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, no exclusions, and no context about the intended workflow. The single phrase provides zero actionable usage instructions.

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