db_start_version_upgrade

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It implies an asynchronous start by saying it returns a status message 'confirming upgrade start,' but it does not describe prerequisites, downtime risk, reversibility, or what happens on failure. These are notable omissions for a database version upgrade mutation.

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 short, organized into Args and Returns sections, and has no redundant filler. It is structurally clean and readable, though it sacrifices useful context for brevity.

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?

An output schema exists and the basic invocation shape is present, so an agent can likely make the call. However, for a mutation without annotations, the description lacks important contextual links: how to determine valid versions, whether the operation is backgrounded, and what consequences or prerequisites are involved.

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 schema has 0% description coverage, so the Args section is the only source of meaning. It clarifies database_id as 'the database ID or label' and version as the target. It does not explain acceptable version formats or mention that db_list_available_versions may be needed to choose a valid target.

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 a specific verb and resource: 'Start a database engine version upgrade.' This clearly communicates the tool's core action and target. It does not explicitly distinguish itself from sibling tools, but the verb phrase is distinct enough within the database tool family.

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?

There is no guidance on when to use this tool versus related tools such as db_list_available_versions, db_start_maintenance, or db_get_maintenance_updates. The description is purely declarative and leaves selection and prerequisites entirely to the agent.

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