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

readOnlyHint=true already tells the agent this is a safe read, so the description's main addition is the API endpoint mapping (GET /api/v1/roles/{role_id}/permissions). It does not describe pagination behavior despite page_size/next_token params, nor return shape. Adequate given annotation coverage, but not rich.

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 with zero filler, purpose front-loaded before the endpoint reference. Every element earns its place.

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 list tool with full schema coverage and no output schema, the description supplies enough to invoke correctly. The only missing piece is explicit pagination/return guidance, which the params largely cover.

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 role_id, page_size, and next_token are already documented in the schema (including the 1-100 bound and cursor semantics). The description adds nothing beyond the schema, so the baseline 3 is correct.

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?

States a specific verb (list) and resource (permissions) and narrows scope to 'one role', which implicitly distinguishes it from kinde_list_permissions (all permissions) and kinde_list_roles. It is clear, though it never names the sibling endpoints an agent might confuse it with.

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 when-to-use guidance, no exclusions, and no mention of the closely related kinde_list_permissions or kinde_get_user_permissions_in_organization alternatives. The agent must infer from the name alone which listing scope applies.

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