overwrite_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, but it only restates the name. It does not mention that this overwrites the selected clip with source monitor content, side effects, undo behavior, or any other operational traits.

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 a single short sentence, so it is concise, but it is also under-specified, essentially serving as a label. It does not provide useful information beyond the tool name, making it minimally adequate.

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 complexity of Premiere Pro operations, this description is incomplete. It lacks context about the operation's effect, return values, or relationship to other timeline operations. The absence of annotations and output schema further increases the need for descriptive context, which is not met.

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 parameters, so the schema fully covers parameter definitions. The baseline for 0 parameters is 4, and the description doesn't need to add parameter details since there are none.

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: overwrite from source' identifies the tool as an overwrite operation using source footage, but it does not explain what this entails in the Premiere Pro context. It fails to distinguish it from sibling tools like 'overwrite_clip' or 'insert_from_source', making it ambiguous.

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 mention of prerequisites, common use cases, or comparison with sibling tools such as 'insert_from_source' or 'overwrite_clip'. The description provides zero usage direction.

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