Undo Last Organization Operation

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

Annotations already declare destructiveHint=true, so the destructive nature is known. The description adds that it reverses moves and renames, which is useful behavioral context beyond the annotation. However, it doesn't elaborate on side effects (e.g., whether undoing is itself reversible, whether it requires rollback permissions, or what happens if there's no previous operation). The description adds some value but not substantial detail.

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, efficient sentence with no filler words. It front-loads the primary action and is easy to parse quickly. While it's brief, there's no wasted content, so it scores well on conciseness.

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 destructive tool with two optional parameters and no output schema, this description is incomplete. It doesn't explain the manifest_id requirement, what happens if no prior operation exists, what the response looks like, or how it interacts with the organization workflow. Given the tool's complexity (undoing file operations) and the lack of structured context, it should provide more guidance.

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 schema description coverage is 0%, so the description must compensate for undocumented parameters. It fails to explain what manifest_id is or how it relates to the undo operation, and it doesn't mention response_format at all. The description adds no meaning beyond what the bare schema provides, making it inadequate for an agent to correctly supply the parameters.

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 the tool's purpose with a specific verb ('reverses') and resource ('file moves and renames from a previous organization task'). It clearly distinguishes this from the organizing tools among the siblings, though it doesn't explicitly contrast with any specific sibling. Overall, it's clear but not exceptionally detailed.

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, nor does it mention any prerequisites or exclusions. It doesn't explain that this should be used after an organization operation, or that it might require a manifest_id. There's no context about when not to use it or what conditions make it appropriate.

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