insert_from_source

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 does not state any effects, prerequisites, or side effects of the operation, offering only a label. The agent has no idea what happens when invoking this tool.

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 extremely short, but brevity here is under-specification rather than conciseness. It lacks structure and substantive content, similar to a tautological one-liner that wastes the reader's time without delivering actionable 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?

The tool appears to perform a meaningful editing action in Premiere Pro, yet the description provides zero context. There are no annotations, no output schema, and no parameter documentation. A complete and usable description would explain insert semantics, relationship to source monitor, and differences from overwrite_from_source.

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 defined parameters, and the base score for zero-parameter tools is 4. The description adds no parameter details, but there is also nothing to clarify. The schema's permissive additionalProperties is not addressed, but this is not a critical gap given no formal parameters exist.

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: insert from source' merely restates the tool name with the filler phrase 'expanded operation,' which adds no meaning. It fails to specify the verb scope or distinguish the tool from sibling tools like overwrite_from_source.

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 context about insertion behavior, playhead requirements, or comparison to overwrite_from_source is provided, leaving the agent without any usage direction.

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