TDQS

A4.1/5.0
Behavior4/5

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

The description discloses the key behavioral outcome: the nested sequence clip is replaced by its contents. It also scopes the operation to the timeline. While annotations are sparse, the description does not go into reversibility/undo behavior or project-level side effects, so it is strong but not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single concise sentence that front-loads the action and clearly states the replacement behavior. Every word earns its place, with no redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple, has one fully documented parameter, and an output schema exists. The description sufficiently communicates the operation and its observable effect on the timeline; no additional context is needed for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter, node_id, is already fully described in the schema as the Node ID of the nested sequence clip to unnest. The tool description does not add extra parameter guidance, but schema coverage is 100%, so the baseline applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Unnest') and identifies the exact resource ('a nested sequence on the timeline') and the resulting behavior ('replacing it with the contents of the nested sequence'). This makes it easy to distinguish from the inverse sibling tool nest_clips and related sequence tools like duplicate_sequence or delete_sequence.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is clear from the operation itself: when a nested sequence clip should be flattened into its contents on the timeline. However, the description does not explicitly say when not to use it or mention alternatives such as nest_clips for the inverse operation.

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