db_get_maintenance_updates

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 discloses that the tool returns a list of available maintenance updates, but doesn't state whether this is a read-only operation, whether it requires special permissions, whether it triggers any side effects, or what the output structure looks like. The description is minimal and doesn't add behavioral context beyond the basic return type.

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 and front-loaded with the main purpose. The Args/Returns structure is clear and scannable. It earns its place with no filler, though it could add a bit more context without becoming bloated.

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 one-parameter read tool, the description is mostly adequate, but with no annotations and no output schema details, an agent doesn't know what the returned list looks like, whether the operation is safe, or how to interpret the results. The sibling context (db_start_maintenance, db_get_migration_status) suggests this is part of a maintenance workflow, but the description doesn't explain that relationship.

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%, so the description must compensate. It does explain that database_id is 'The database ID or label', which adds a small amount of meaning beyond the schema's bare string type. However, it doesn't clarify the format of the ID/label, how to find it, or any constraints (e.g., must be a UUID vs a name).

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 verb ('Get') and resource ('available maintenance updates for a database'), which clearly distinguishes it from sibling tools like db_start_maintenance or db_list_backups. It doesn't explicitly name a sibling alternative, but the resource and action are specific enough to identify the tool's purpose.

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 implies usage context: call this when you need to see available maintenance updates before starting maintenance. However, it doesn't explicitly state when to use this vs alternatives like db_start_maintenance or db_get_migration_status, nor does it mention any prerequisites (e.g., database must exist).

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