Get Time Range

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

Annotations already declare this tool as readOnly, idempotent, and non-destructive. The description adds specificity by naming the exact data items returned, but does not disclose any additional behavioral traits (e.g., format, units, or response details). Given the high annotation coverage, this is adequate but not beyond expectations.

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 concise sentence that directly states the tool's function with no extraneous information. It is well-structured and front-loaded.

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 simple, parameterless getter with annotations and an output schema, the description provides sufficient context. It clearly states what the tool retrieves, and the remaining details are covered by annotations and schema.

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 is empty (0 parameters), so schema description coverage is 100%. The description does not need to add parameter semantics, thus meeting the baseline score of 4.

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 clearly states that the tool retrieves 'playback range, animation range, and current time,' using a specific verb ('Get') and naming the resources. It effectively distinguishes itself from sibling tools like 'animation.set_time' and 'animation.set_time_range' which are setters.

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?

The description implies usage as a getter but provides no explicit guidance on when to use this tool versus alternatives or any prerequisites. The context from sibling names suggests differentiation, but the description itself lacks direct usage instructions.

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