db_delete_user

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

With no annotations, the description must carry the behavioral burden. It only says 'Delete' and mentions a status message; it does not disclose whether deletion is permanent, whether it affects active connections or dependent objects, or what permissions are required. For a destructive operation this is a noticeable gap.

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 tight and front-loaded: one purpose sentence, then a clean Args section, then a Returns note. No filler or repetition of schema types, and every line earns its place.

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 two-parameter deletion tool this is mostly sufficient: both params are explained and a return value is described. However, it lacks usage context, behavioral caveats, and any mention of failure modes or side effects, so it is not fully complete even for a simple tool.

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%, but the description defines both parameters: database_id as 'The database ID or label' and username as 'The username to delete.' This adds meaning beyond the bare string types in the schema, though the definitions are minimal.

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 and resource: 'Delete a database user.' This clearly distinguishes it from nearby siblings like db_delete (deletes a database) and user_delete (deletes an account), while aligning with db_create_user/db_update_user in the same 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?

The intended use is implied by the name and first line, but there is no explicit guidance on when to choose this tool over alternatives, no prerequisites, and no exclusions. It is adequate for a straightforward deletion but leaves the agent to infer context.

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