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

The description explicitly shows `GET /api/v1/databases/{db_cluster_id}/admins`, indicating a read-only list operation, but annotations declare readOnlyHint=false. This is a direct contradiction. No other behavioral context (e.g., authentication, rate limits) is provided.

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, well-structured sentence that includes all essential information: the action, resource, and endpoint. There is zero waste or fluff.

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 list tool, the description is nearly complete. It states the resource and endpoint, but doesn't mention the return format (e.g., array of user objects) or any potential pagination. The annotation contradiction slightly undermines completeness, but the description itself is adequate.

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 schema provides 100% coverage for the single parameter db_cluster_id with a clear description. The tool description adds no further meaning beyond referencing the parameter in the endpoint, so the baseline of 3 is appropriate.

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 clearly states the action ('Возвращает список' - returns a list), the resource (users/admins of a database cluster), and includes the exact endpoint with the parameter. It effectively distinguishes from siblings like get_database_admin (single admin) and list_database_clusters (list clusters).

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 (e.g., get_database_admin for a single admin). The description only states what it does, leaving the agent to infer usage context from the tool name and endpoint.

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