encode_file

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states only 'encode file' with no mention of side effects, duration, output handling, or whether the operation is read-only or destructive. This is a significant transparency gap for what is likely a heavy 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 a single sentence but is severely under-specified. 'Premiere Pro expanded operation' is filler, and 'encode file' repeats the tool name. It does not earn its place since it provides no useful information, embodying under-specification rather than concise clarity.

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 tool's likely complexity (encoding involves input source, encoding settings, output destination, and potential for long execution), the description is wholly inadequate. With no annotations, no output schema, and an open input schema, the agent has no basis for understanding what this tool does or how to invoke it 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?

Although there are 0 defined parameters and schema coverage is trivially 100%, the schema allows additionalProperties (any property), implying an undocumented parameter space. The description gives no hint about what properties are accepted (e.g., file path, codec settings) or whether the tool relies on context (like selected items). The baseline of 4 for 0 params is not met because the open schema creates ambiguity that the description fails to resolve.

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: encode file' essentially restates the tool name without explaining what the expanded operation does or how it differs from sibling tools like start_batch_encode or encode_project_item. It is a tautology with a vague qualifier, providing no specific verb-resource 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?

There is no guidance on when to use encode_file versus other encoding/exporting tools in the sibling list. The description offers no context, prerequisites, or exclusions, 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.
