B3.2/5.0

Behavior3/5

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

No annotations are provided, so the description must carry the full burden. It usefully discloses HTTP POST, mutation behavior, refusal under --readonly safety profiles, authentication requirements with administrator approval and scopes, and that the response is returned as JSON. However, it omits idempotency (requestId is in the schema but not discussed), error behavior, and quota/rate-limit context.

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

Conciseness3/5

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

The core purpose is front-loaded, but the description is a long doc dump with a truncated authorization URL and a terse bracketed suffix. It contains useful information, but could be tightened and better organized for agent consumption.

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

Completeness4/5

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

Given the tool's complexity, lack of annotations, and rich schema/output schema, the description covers purpose, authentication, request body passing, return format, and sibling awareness. It is close to complete for an agent to call it correctly, though it omits idempotency and error-handling hints.

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 100%, so the schema already documents all parameters thoroughly. The description adds only a brief note that the body is a JSON Space object and can be passed via `params` or `body_file`, while listing a few fields already present in the schema. This is adequate but adds little beyond the structured data.

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

Purpose4/5

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

The description states a specific verb and resource ('Creates a space') and clarifies two creation modes (named space or group chat in Import mode). It does not explicitly differentiate from siblings in the main sentence, though a sibling list appears at the end.

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?

The description mentions two modes but gives no explicit guidance on when to use this tool versus siblings like setup, findGroupChats, or findDirectMessage. It only lists sibling names without conditions for selecting among them.

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