set_zero_point

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'set zero point,' implying a state change but not explaining scope, persistence, side effects, prerequisites, or whether the action can be undone.

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 very short and front-loaded, but 'expanded operation' adds little value and the sentence is more under-specified than efficiently 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?

Without annotations, output schema, or parameter context, the description leaves significant gaps: it does not say what zero point refers to, which sequence or monitor is affected, or what observable results follow the call.

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 zero documented parameters and the schema coverage is 100%, so the description has no parameter meanings to add. The baseline of 4 applies, though the schema's additionalProperties:true leaves unconstrained extra properties unspecified.

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 and target: 'set zero point' in Premiere Pro. It is clear enough for an agent familiar with the domain, though it does not contrast with sibling setters like set_start_time or set_sequence_in_out_points.

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 such as set_work_area, set_playhead_position, or set_start_time. The description provides no context for when setting a zero point is appropriate or what it applies to.

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