Checkout accessory to a user

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

Annotations already declare destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the mutation and irreversibility profile is covered. The description adds the concrete endpoint and a spec-compliance note about field naming, but says nothing about the confirm="YES" gating behavior, stock-depletion effects, or failure modes of a non-idempotent destructive write.

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 sentences, zero filler. The action and endpoint are front-loaded, and the caveat follows as a short parenthetical note.

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 destructive, non-idempotent write with no output schema, the description covers the core action and the field-name pitfall but omits the confirm-flag workflow and expected behavior on insufficient stock or invalid user. Adequate to call correctly, but not complete for a destructive operation.

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 is 60%, with `id` and `note` undocumented in the schema, so the description must add value. It does so meaningfully by clarifying that the target-user parameter is named `assigned_user` per the Snipe-IT spec rather than `assigned_to`, preventing a concrete and likely invocation error that the schema itself does not warn about.

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 states a specific verb and resource ("check an accessory out to a user") and pins the exact REST endpoint POST /accessories/{id}/checkout. The resource name cleanly separates it from the many sibling checkout tools (hardware, consumable, component, license seat), though it never names or contrasts those siblings explicitly.

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 verb and resource; there is no statement of when to prefer this over snipeit_checkout_consumable/snipeit_checkout_component or the generic snipeit_raw_request, and no prerequisites (e.g. accessory must have available stock) are given. The one piece of guidance present is the field-naming caveat, which is parameter-level rather than usage-level.

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