mysql_create_user

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 fails to disclose required privileges, behavior on duplicate users, or whether the user is created with authentication plugin defaults. For a mutation tool, more transparency is needed.

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 a single front-loaded sentence, which is concise. However, it lacks necessary details to be truly useful. While not verbose, the minimalism undermines clarity.

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 the tool complexity (3 required params, no output schema, many sibling tools), the description is severely incomplete. It does not address common usage scenarios, error cases, or required permissions, leaving the agent underinformed.

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%, and the description does not explain any parameter. Key information about 'host' (allowed connect hosts), 'password' (authentication method, requirements) is missing. The description adds no value beyond the schema 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 'Create a MySQL user' clearly states the verb (create) and resource (user). It distinguishes from sibling tools like drop_user, alter_user_password, etc. However, it doesn't mention that it also sets a password, which is implicit from the required 'password' parameter.

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 versus alternatives like alter_user_password or grant_privileges. There is no mention of prerequisites or exclusions, which is insufficient for selecting the right tool among many sibling tools.

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