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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only states the operation without mentioning atomicity, partial failure handling, permissions, or side effects. For a batch mutation tool, this is a significant gap.

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 filler. Every word contributes to conveying the tool's purpose and scope.

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?

With no output schema and no annotations, the description is insufficient for a multi-operation tool. It does not explain what the tool returns, whether the operation is all-or-nothing, or what happens if some paths fail. This leaves important behavioral context missing.

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 provides comprehensive descriptions for both parameters (paths and newParent), achieving 100% coverage. The description adds minimal extra semantic value beyond confirming the batch nature, so it meets the baseline for parameter clarity.

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 uses a specific verb ('Move'), clearly identifies the resource ('multiple instances'), and specifies the destination ('to a new parent') plus the batch nature ('at once'). This clearly distinguishes it from the sibling 'reparent_object' tool which handles a single instance.

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 phrase 'multiple instances' and 'at once' gives clear context that this tool is for bulk reparenting operations. However, it does not explicitly state when to use this over the single reparent_object tool or provide exclusions, so it falls short of full guidance.

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