Create Schedule Rotation User

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the mutation and non-idempotency profile is covered structurally. The description adds nothing on top — no mention of duplicate-user handling, position collision behavior, or permission requirements, which matter given idempotentHint=false.

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?

It is a single short sentence with no wasted clauses, so it is concise. But the brevity reflects under-specification rather than efficiency — the one phrase beyond the name ("from provided data") conveys no 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?

Missing the mark. An output schema exists so return values needn't be described, but this is a nested-object write into an open-world resource, and the description supplies none of the operational context (position semantics, duplicate handling, wrapper shape) an agent needs to call it correctly.

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 coverage sits at 50%, so the description should compensate, but it does not: "from provided data" gives no hint about the `data` wrapper, the fixed `type` enum, or the nested `attributes` object. The schema's own `user_id` description ("Schedule rotation user") is circular, and the description does nothing to clarify how position orders users in the rotation.

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 names a specific verb and resource ("Creates a new schedule rotation user"), so the general action is clear. However, "from provided data" is pure filler, and nothing explains what a rotation user actually is (a user assigned to a rotation slot, optionally ordered by position) or how it differs from siblings like create_schedule_rotation or list_schedule_rotation_users.

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 guidance on when to use this versus alternatives such as create_schedule_rotation, list_schedule_rotation_users, or create_override_shift, and no prerequisites stated (e.g., must the rotation exist, must the user be on the team). The agent must infer everything from the name alone.

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