close_sequence

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

While annotations indicate destructiveness (destructiveHint: true), the description does not elaborate on consequences such as unsaved changes, undoability, or side effects on the timeline or project. No additional behavioral context is provided beyond what annotations already convey.

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, front-loaded sentence with no wasted words. It is efficiently structured and easy to parse.

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 close action, the description is adequate but lacks necessary safety context (e.g., whether unsaved changes are lost, if undo is possible). Given medium complexity and no output schema, more detail would improve completeness.

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?

Schema coverage is 100% with a descriptive schema for the single parameter. The description does not need to add extra detail; the baseline score of 3 is appropriate.

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 action ('close'), resource ('sequence tab'), and location ('in the timeline'). It is specific enough to distinguish from sibling tools like close_source_monitor or close_all_source_clips.

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 provides no guidance on when to use this tool versus alternatives (e.g., close_source_monitor, close_all_source_clips) or any prerequisites. There is no mention of use cases or exclusions.

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