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

Annotations only supply destructiveHint=true, so the description carries most of the burden. It discloses nothing about key/name uniqueness constraints, permission requirements, behavior on duplicate keys, or reversibility — all material for a create tool. The REST path is stated but adds little behavioral insight.

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 the purpose front-loaded and no filler. The trailing 'Kinde: POST /api/v1/roles' is API trivia rather than agent-relevant guidance, but it is brief enough not to be a real cost.

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?

There is no output schema, so the description should ideally say what the call returns (e.g., the created role's id/key) and whether the operation is idempotent. For a simple 4-param create the core purpose is covered, but the return side is a 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 each of the four parameters is already documented in the schema. The description adds no extra meaning about required fields, key format, or default-role semantics; 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 and resource ('Create a role') plus the downstream purpose ('can then be granted to users'), which distinguishes it from read-oriented siblings like kinde_list_roles. It does not explicitly contrast with the closest sibling, kinde_create_permission, but the resource noun is unambiguous.

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?

There is no when-to-use guidance beyond the bare purpose statement. The phrase 'can then be granted to users' hints at a workflow order with kinde_grant_user_role_in_organization, but no alternatives, prerequisites, or exclusions are given.

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