unlink_selection

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

The description discloses the mutation action 'Unlink' without side effects, consistent with annotations (readOnlyHint=false, destructiveHint=false). It does not mention prerequisites or behavior when no selection exists, which would improve transparency.

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 front-loads the action and context without any redundant words.

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 simplicity (no parameters, no output schema), the description sufficiently explains the tool's purpose and usage. It could mention what happens if no selection is made, but it is otherwise complete.

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, so the description does not need to add parameter meaning. Baseline is 4 for no parameters, and the description is adequate.

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 verb 'Unlink', the resource 'currently selected video and audio clips', and the context 'in the active sequence', distinguishing it from siblings like 'link_selection'.

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 when to use the tool (unlink selected clips), but does not explicitly state when not to use it or mention the sibling tool 'link_selection' as an alternative. The context is clear but could be more direct.

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