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 mentions creating and previewing variants, but fails to describe key traits: whether actions are reversible (e.g., 'finalize' might be permanent), permission requirements, side effects on the timeline, or how variants are stored/managed. This leaves significant gaps for a tool with multiple action types.

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 highly concise and front-loaded, using two clear sentences that directly state the tool's function and key actions. Every word earns its place, with no redundant or vague phrasing, making it easy to scan and understand quickly.

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 complexity (multiple actions via a single enum parameter) and lack of annotations or output schema, the description is incomplete. It covers the high-level purpose but omits details on behavioral outcomes, error conditions, or what 'finalize' entails. For a tool with varied operations, more context on usage and results would be beneficial.

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 100% description coverage, with the 'action' parameter fully documented via enum and descriptions. The tool description adds minimal semantics beyond the schema—it hints at 'create alternate clip versions' and 'preview them', which loosely maps to some enum values like 'create_from_active', but doesn't provide additional context on parameter usage or interactions.

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 the tool's purpose: managing variant controls for comparing different clip versions, with specific actions like creating alternates and previewing. It uses concrete verbs ('create', 'preview') and identifies the resource ('clips'), but doesn't explicitly differentiate from sibling tools like 'duplicate_detection' or 'compare_frame' that might have overlapping functionality.

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 context ('preview them before committing'), suggesting it's for auditioning changes without permanent application. However, it lacks explicit guidance on when to use this versus alternatives (e.g., 'duplicate_detection' for duplicates or 'compare_frame' for visual comparisons), and no exclusions or prerequisites are mentioned.

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