mysql_bind_user

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether this is destructive, whether it fails when the user already exists, whether the password is stored in plaintext, what permissions the caller needs, or what the response contains. For a credentialed account-creation mutation this is a serious 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?

At four words it is not concise but under-specified; brevity here costs essential information rather than removing waste. The MySQL prefix is the only front-loaded context.

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?

A five-parameter, all-required mutation tool with no annotations, no output schema and no parameter documentation is nowhere near complete. Nothing an agent needs in order to invoke it correctly is present.

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?

Five required parameters (database, db, username, password, permission) with 0% schema description coverage, and the description supplies no parameter meaning at all. The overlapping 'database' and 'db' fields in particular are left unexplained, so an agent cannot know which to populate or whether both are needed.

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 gives a resource (MySQL user) and two verbs (bind/create), which is enough to distinguish it from unrelated siblings like list_backups or remove_container. However, 'Bind/create user' is ambiguous about which operation is actually performed and what 'bind' means (attaching an existing user to a database with privileges), leaving the agent to guess.

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 when-to-use guidance and no mention of the closely competing siblings mysql_change_access, mysql_change_password, or postgresql_bind_user. The only signal is the MySQL prefix, which the agent must infer on its own.

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