capture_frame

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

With no annotations, the description must carry the full burden of disclosing behavior. It does not mention effects, side effects, permissions, or expected outcomes. The phrase 'expanded operation' is generic and uninformative.

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?

While extremely short, this is under-specification rather than concise utility. The single phrase 'Premiere Pro expanded operation: capture frame' restates the tool name and does not earn its place by adding information. Concise is not the same as sparse to the point of uselessness.

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?

There is no output schema, no annotations, and the description does not describe the tool's purpose, behavior, or selection criteria. Given the large number of sibling tools performing similar actions, this description is inadequate for an agent to understand or invoke the tool 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 the input schema is empty, so per the rubric the baseline is 4. The description adds no parameter details, but since there are none to document, this score is appropriate.

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 'Premiere Pro expanded operation: capture frame' is essentially a tautology—it restates the tool name without specifying what capturing a frame entails or how it differs from sibling tools like export_frame, freeze_frame, or set_poster_frame. No verb+resource clarity is provided beyond the name itself.

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. The description offers no context, prerequisites, or exclusions, leaving the agent to guess the appropriate selection scenario.

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