db_create_logical_database

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

With no annotations, the description carries the full burden of behavioral disclosure. It states that the tool creates a logical database and returns its information, but it does not mention permissions, naming constraints, idempotency, failure behavior, or any side effects on the parent managed database instance. This is a notable gap for a mutating create operation.

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 concise and well-structured: a clear one-sentence purpose followed by compact Args and Returns sections. There is no filler, and the core action is front-loaded.

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?

For a simple two-scalar-parameter tool with an output schema, the essentials are present: purpose, parameter meanings, and return behavior. However, because it is a mutating operation with no annotations and no usage guidance, an agent still lacks context about prerequisites, constraints, and side effects, making it only minimally complete.

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?

Despite 0% schema description coverage, the description provides meaningful glosses for both required parameters. Describing database_id as 'The database ID or label' is genuinely useful for invocation, though the definition of name is somewhat self-evident. It compensates for the schema's lack of semantic detail, though not richly.

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 states a specific action: 'Create a new logical database within a managed database instance.' This clearly identifies the verb and resource, and the phrase 'within a managed database instance' helps distinguish it from tools like db_create. However, it does not explicitly name or contrast sibling tools, so it stops short of full sibling differentiation.

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 gives no guidance on when to use this tool versus alternatives such as db_create, db_create_read_replica, or db_create_connection_pool. There are no usage conditions, exclusions, or explicit context cues beyond the tool name itself.

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