close_sequence

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely restates the tool name ('close sequence') and does not reveal whether the operation is destructive, whether it prompts for saving, whether it affects the active sequence only, or whether it can fail due to unsaved changes.

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 short but wasteful: 'Premiere Pro expanded operation:' is boilerplate filler that does not aid an agent's decision-making. The actual instruction 'close sequence' is minimally concise but lacks the necessary context to be genuinely useful.

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 no annotations, no output schema, and a simple but destructive-sounding operation, the description is incomplete. It does not state whether the active sequence is closed, how this relates to set_active_sequence, or what state the user sees afterward. An agent cannot determine the tool's full effect from this definition.

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 and the schema coverage is 100%, so there is no parameter ambiguity. The baseline of 4 for no-parameter tools applies, though the description adds no useful semantic detail beyond the absence of arguments.

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 states a clear verb ('close') and resource ('sequence'), so an agent can tell this operates on a sequence rather than a project or source clip. However, it does not differentiate between closing the active sequence versus a specified sequence, and the phrase 'expanded operation' adds no meaning.

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 such as close_project, close_source_monitor, or delete_sequence. The description gives no context about prerequisites, whether the active sequence is closed, or what happens to unsaved changes.

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