get_value_at_time

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

With no annotations provided, the description bears full responsibility for behavioral disclosure, but it provides none. There is no information on side effects, requirements, return values, or edge cases, leaving the tool's behavior entirely opaque to the agent.

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 not concise in a meaningful way; it is under-specified and tautological. The few words it uses add no informative value beyond restating the tool name, so the brevity does not earn its place.

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 lack of annotations and output schema, the description needed to provide substantial explanatory context but offers none. The tool appears to be a getter with no parameters, yet the description does nothing to clarify its purpose, expected output, or relationship to the many sibling tools, making it wholly inadequate.

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 description has no parameter semantics to explain. According to the rubric, 0 params sets a baseline of 4, and there is no contradiction or omission in this dimension.

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: get value at time' is largely a restatement of the tool name and does not specify what resource or action is actually being performed. It fails to convey what 'value' refers to or what 'at time' means in this context, providing no differentiation from any sibling tools.

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. The description merely repeats the tool name without any contextual or alternative-based suggestions, so an agent receives no help in selecting it appropriately.

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