Behavior3/5

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

With no annotations, the description carries the behavioral burden. It explicitly discloses the potentially destructive 'remove collaborators' action, which is useful. However, it does not mention permission requirements, whether updates are applied atomically, reversibility, or effects on existing access, leaving significant behavioral gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with no redundant phrasing. It front-loads the core action and resource scope, wasting no words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a batch mutation tool with no annotations and no output schema, the description is too thin. It lacks usage context, prerequisite information, and behavior around the updates array. An agent is left without enough guidance beyond the raw schema to know how to safely and correctly invoke the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It explains that roles can be updated and collaborators removed, and that the target is a file or folder, which maps to itemType and the updates array. It does not describe path or itemId, and does not clarify how the updates array should be structured beyond what the schema already shows, so compensation is partial.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a precise action — updating collaborator roles or removing collaborators — on a specific resource (file/folder). This clearly distinguishes it from siblings like box_update_shared_link, which targets shared link settings, and box_share_content, which is about sharing rather than permission changes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to choose this tool over box_share_content or box_update_shared_link. The description implies a use case for managing collaborator permissions but does not state prerequisites, exclusions, or when an alternative would be more appropriate.

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