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

With no annotations, the description is the sole source of behavioral disclosure. It reveals the creation action but omits important context such as required permissions, reversibility, potential errors, or what happens to existing spaces. It also does not clarify the behavior of 'with members' beyond 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 a single, unambiguous sentence that conveys the core functionality without any wasted words, making it highly concise and well-structured.

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?

The tool is simple with two well-documented parameters. However, the description does not mention return values or handle edge cases, and there's no output schema. For a creation operation, this is a minor gap but not critical due to the simple scope.

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 already has descriptive parameters (displayName description, userNames with example), and the description only echoes 'with members.' It adds no additional semantics beyond what the schema provides. With 100% schema coverage, the baseline is 3.

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 the specific verb 'Creates' and names the resource 'Google Chat space' while noting it includes members, clearly distinguishing it from sibling tools like chat_listSpaces or chat_sendMessage.

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 implies its use for creating a space but does not explicitly state when to use it versus alternatives, nor does it mention any prerequisites or exclusions. The purpose is clear enough for basic guidance, but it lacks explicit usage context.

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