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

Annotations only supply destructiveHint=true, so the description usefully adds that the operation is reversible via kinde_revoke_user_role_in_organization and identifies the underlying POST endpoint, confirming a state-mutating authenticated API call. It adds real context without contradicting the destructive hint (a grant is reversible yet still a state change).

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 plus an endpoint reference; the operation is front-loaded and every clause (scope, reversibility, API path) carries distinct information.

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 three-parameter mutation with no output schema, the description plus annotations and a fully documented schema cover what an agent needs. The only gap is that no return value is described — acceptable given there is no output schema, and no prerequisites (e.g. existing role) are mentioned.

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% with all three required parameters documented inline, so the schema already carries the parameter burden. The description only restates the user/org cardinality and adds nothing about id formats or lookup sources — baseline 3 applies.

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+resource combination ('give one user a role within one organization') with explicit scoping to a single user/org pair, which distinguishes it from the sibling 'kinde_grant_user_permission_in_organization' by resource type and from 'kinde_add_users_to_organization' by cardinality.

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 verb and the named undo path, but there is no explicit when-to-use guidance, no prerequisites (e.g. role must already exist via kinde_create_role), and no statement of when the permission-granting sibling is preferred.

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