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

Annotations already declare this is a non-read-only, open-world, non-destructive operation. The description adds that it returns the room link and groups multiple links, but it does not disclose default access behavior, idempotency, permissions, or what happens to the included links; the 'folders' claim is also unsupported by the schema.

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 two short sentences and front-loads the core action. The metaphorical 'one link and one door' phrase and the unsupported 'with folders' detail slightly reduce precision but do not bloat the text.

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?

There is no output schema, so stating that it returns the room link is useful. However, for an open-world creation tool with five parameters and no annotations covering creation semantics, the description does not explain access defaults, NDA implications, or folder behavior, leaving meaningful gaps.

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?

Schema description coverage is 80%, so the schema already documents the access modes, NDA text, watermarking, and link formats. The description adds little parameter-specific meaning beyond referencing 'my links' and the return value; 'folders' does not map to any parameter.

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 names a specific verb and resource: putting several links into one data room and returning the room link. It is distinguishable from siblings like list_links or open_link, though the metaphor "one link and one door" and the mention of folders (not present in the schema) add some ambiguity.

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 link_for_person, send_artifact, or update_link. It also omits prerequisites, constraints, or when not to create a data room.

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