get_export_file_extension

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

Since no annotations are provided, the description carries the full behavioral disclosure burden, but it only restates the operation. It does not state whether the call is read-only, what happens if no export configuration exists, or how the extension is formatted in the return value. 'Expanded operation' hints at a category but explains no behavior.

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 and places the core resource first, which is good. However, 'Premiere Pro expanded operation' is vague filler that does not earn its place, and the overall brevity crosses into under-specification because important operational details are omitted.

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?

For a no-argument getter, the description is nearly minimal, but an agent still does not know what the output looks like, whether it depends on active export settings, or what error or empty state to expect. The absence of an output schema makes this gap more significant, so the tool is not complete enough for confident invocation.

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 declared parameters, and the schema's additionalProperties:true adds no meaningful constraints, so there are no parameter semantics to document. The description's reference to 'export file extension' clarifies the domain rather than a parameter. Given the 0-parameter baseline, a 4 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 uses a clear get+resource pattern, stating that the tool retrieves the export file extension. It is distinguishable from the large sibling set because the resource is specific and no other sibling targets extension retrieval. However, the phrase 'expanded operation' is vague and adds little to purpose clarity.

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?

No guidance is given on when to use this tool versus alternatives, nor any prerequisites such as an active project or configured export settings. The description is purely definitional and leaves the agent to infer usage entirely from the tool name.

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