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

The readOnlyHint=true annotation already tells the agent this is a safe read, lowering the disclosure bar. The description adds only the underlying Kinde endpoint path; it says nothing about pagination, result caps, or how empty results are represented. Useful traceability context, but not rich behavioral detail.

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?

Two short sentences, front-loaded with the action and scope, with zero filler. The trailing endpoint path is slightly redundant for an agent that already knows the tool name, but it is compact and harmless.

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 read-only, two-parameter list tool with full schema coverage and a safety annotation, the essentials are covered. With no output schema, however, the description never indicates the shape of the returned permission data or whether the list can be paginated or truncated, which is a modest but real gap.

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 100%, so both user_id and org_code are already documented in the schema. The description conveys only that one user and one organization are involved, adding no format, identifier-style, or defaulting detail beyond the structured fields. Baseline 3 applies when the schema does the heavy lifting.

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 specific verb+resource+scope: 'list the permissions one user holds in one organization.' This is unambiguous and separates it from broad permission-listing siblings like kinde_list_permissions. It does not, however, explicitly contrast itself with its near-twin kinde_get_user_roles_in_organization, so sibling differentiation is left to the reader.

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 only implied by the scope wording ('one user ... one organization'). There is no statement of when to prefer this over kinde_get_user_roles_in_organization or kinde_list_permissions, and no prerequisites such as required scopes or org membership. Adequate but with a clear routing gap given the crowded sibling set.

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