get_user_hwid_devices

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the "[READ]" tag adds nothing. Beyond that, the description says nothing about return shape, pagination, or any per-user scoping/authorization behavior, so it contributes almost no behavioral context.

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 lines, front-loaded with the action, and nothing redundant or padded. It is efficient, though the brevity reflects under-specification rather than disciplined editing.

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?

With no output schema, no annotation details beyond read-only, and a completely undocumented parameter, the description leaves an agent unable to know what is returned or how the userId is sourced. The minimum needed to invoke it correctly is largely absent.

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 0%, so the description is expected to compensate for the single userId parameter. The route fragment ":userId" merely echoes the parameter name and does not clarify whether it accepts a numeric ID, UUID, or where the caller obtains it.

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?

"Get user HWID devices" states a verb and resource, and the route confirms it is a read of HWID devices scoped to a user. However, it essentially restates the tool name and gives no basis to distinguish it from close siblings like get_hwid_devices, get_hwid_devices_stats, or get_top_users_by_hwid_devices.

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 call this versus the other HWID tools (global device list, HWID stats, top-users-by-HWID). The only context is the raw endpoint, which an agent must interpret on its own.

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