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

The description adds no behavioral information beyond what annotations already declare. Annotations indicate readOnlyHint=false and destructiveHint=true, implying a write operation with potentially destructive side effects, but the description merely says 'create'. It does not disclose what gets created, what existing resources might be affected, or any authentication/role requirements. It adds zero value over the structured metadata.

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 extremely short but under-specified. It is not a model of conciseness; it omits essential context. There is no front-loaded information because there is no information at all. This is an under-specification, not a deliberate concise summary.

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 a creation operation with no output schema, several parameters including nested objects and enums, and destructive annotations. The description 'create secrets manager' does nothing to help an agent understand what a secrets manager is, what required auth values look like, or what side effects occur. For such a complex tool, this is wholly inadequate.

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 description contains no information about any of the five parameters (dcs, auth, name, type, workspace_id). Even though the schema provides some descriptions for three fields, the description itself adds no meaning. It does not explain the enum values for type, the structure of auth, or the role of workspace_id. With 60% schema coverage, the description could compensate but does not.

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?

Tautological: description restates name/title.

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 usage guidance is provided. There is no mention of when to use this tool instead of alternatives like list_unified_workspace_secretsmanagers or get_unified_workspace_secretsmanager, nor any indication of prerequisites or conditions. The description gives no context to choose between tools.

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