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

Annotations already declare read-only, idempotent, and non-destructive; the description adds useful required-scopes (databases:read) and the endpoint. This is meaningful auth context beyond the annotations, and there is no hint of hidden side effects.

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 compact and front-loaded with the operation, followed by useful HTTP, category, scope, and read-only lines. It is slightly redundant with the annotation metadata, but nothing is verbose or irrelevant enough to penalize heavily.

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 zero-parameter read-only list operation, the description provides the endpoint, category, required scope, and safety indication. It does not describe response fields, but 'List MySQL users' adequately conveys what is returned, and an agent can invoke the tool correctly without additional information.

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 input schema has zero parameters and 100% annotation/schema coverage, so the baseline of 4 applies. There are no parameters for the description to explain.

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 opens with 'List MySQL users', a specific verb and resource, and the HTTP line confirms GET /v1/mysql-users. It is clear but does not explicitly differentiate itself from the sibling tool that fetches a single MySQL user by ID.

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 about when to use this list operation instead of the per-ID MySQL-user tool or related database/remote MySQL tools. The read-only and scope information is helpful context but does not tell an agent which alternative to select in different situations.

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