superset_get_current_user_roles

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

Annotations are absent, so the description carries the full burden. It discloses the return format (JSON with IDs and names) and clarifies that the current user is the mcp_service. However, it does not explicitly state that this is a read-only operation, nor does it mention potential errors, authentication requirements, or behavior when no roles exist.

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, consisting of one clear sentence plus a brief return note. Every word contributes to understanding, with no redundant or irrelevant content.

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 zero-parameter getter with an output schema, the description adequately covers purpose and return shape. It does not discuss edge cases like empty role lists or required permissions, but these are not critical given the tool's simplicity and the presence of an output schema.

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 tool has zero parameters, so the schema already covers everything. With 100% schema description coverage and no params, the description adds no parameter-specific semantics, which is appropriate. The baseline for zero params is 4.

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?

Clearly states 'Get the list of roles for the current user', specifying the verb, resource, and scope. Distinguishes from siblings like superset_role_list (all roles) and superset_get_current_user (current user info) by focusing on roles for the current user.

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?

Usage is implied by the name and description (to retrieve current user's roles), but no explicit guidance is given about when to prefer this over alternatives like superset_role_list or superset_get_current_user. No exclusions or when-not-to-use conditions are mentioned.

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