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

No annotations are provided, so the description carries the full burden. It states 'Get' implies a read operation, but doesn't disclose behavioral traits like whether it requires prior authentication, returns sensitive data, has rate limits, or what the output format is. This is a significant gap for a tool handling authentication info.

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 wasted words. It's appropriately sized and front-loaded, making it easy to scan quickly.

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?

Given the complexity (authentication tool with no annotations, 0% schema coverage, no output schema), the description is incomplete. It lacks details on usage, parameters, output, and behavioral context, making it inadequate for effective tool selection and invocation.

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 0%, with one parameter 'body' as a nested object. The description adds no meaning beyond the schema—it doesn't explain what 'body' should contain (e.g., request details, filters) or its purpose. This fails to compensate for the low schema coverage.

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 'Get Google Cloud authentication information' clearly states the action (Get) and resource (Google Cloud authentication information), but it's vague about what specific information is retrieved (e.g., tokens, credentials, status). It doesn't distinguish from siblings, though no obvious authentication siblings exist in the list.

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?

No guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, context (e.g., after setup, during errors), or related tools like 'GetCloudCreds' or 'CreateCloudCreds' that might handle authentication aspects.

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