create_db_instance_account

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 only states 'Create a new account,' implying a mutation, but does not disclose side effects, required permissions, reversibility, error conditions, or any other behavioral traits.

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 somewhat verbose with a repetitive list of parameters that largely mirrors the schema. The first sentence is concise, but the list could be streamlined or omitted if the schema provides adequate documentation.

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 0% schema description coverage and no output schema, the description is incomplete. It does not explain the return value behavior (just says 'The response'), error handling, or prerequisites. Sibling tools like describe_db_instance_accounts exist but are not mentioned for guidance.

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 lists parameters with phrases like 'The region ID of the RDS instance,' which merely restates the parameter name. With 0% schema description coverage, the description should add format, constraints, or examples, but it adds minimal semantic value beyond the schema's field names.

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 starts with 'Create a new account for an RDS instance,' clearly stating the verb 'create' and the resource 'account for RDS instance.' However, it does not differentiate from sibling tools that also create resources (e.g., create_db_instance), but given the distinct resource type, it is clear enough.

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 vs. alternatives, such as when to create an account versus modifying security settings or describing accounts. The description lacks context for selection.

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