set_xmp_metadata

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

No annotations are provided, so the description carries the full burden. It only states that the tool sets XMP metadata, but discloses nothing about side effects, overwrite behavior, required permissions, reversibility, or what exactly is modified. This is a serious transparency gap for a mutating operation.

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 short, but it is under-specified rather than concise. The phrase 'Premiere Pro expanded operation' is filler that does not earn its place, and the rest is a bare restatement of the tool name. It fails to convey meaningful information in a structured way.

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?

With no parameters, the schema provides no help. The description is too vague to be complete: it does not state what entity the XMP metadata is set on, whether it applies to selected clips, the current project, or something else. In a large suite of similar tools, this omission is critical.

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 has zero parameters and 100% schema description coverage, so the baseline is 4. The description adds no parameter information, but none is needed since the operation takes no explicit arguments.

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 'set xmp metadata' is essentially a restatement of the tool name 'set_xmp_metadata', with the vague prefix 'Premiere Pro expanded operation' adding no specific semantic detail. It does not distinguish itself from sibling tools like get_xmp_metadata or set_project_panel_metadata.

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 prerequisites, and no examples. The description gives no context about the target entity (e.g., selected clips, project items) or when this operation is appropriate.

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