get_system_status

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

No annotations are provided, so the description carries the full burden; 'Get' plus the metric list reasonably conveys a read-only operation, and naming CPU/memory/uptime tells the agent what comes back. It does not state whether values are live or cached, whether the device must be reachable, or what happens for an unknown/offline device ID.

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?

A single front-loaded sentence with the returned metrics in parentheses and no filler. Nothing extraneous and nothing buried.

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 one-parameter read tool with a fully documented schema and no output schema, the description largely suffices: it names the resource, the scope, and the returned metrics. The remaining gaps (freshness of metrics, behavior on unreachable devices) are modest but real.

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 100%, and the schema already documents device_id as 'Device ID or system-ip'. The phrase 'for a device' in the description adds nothing beyond that, so the 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?

Clear verb+resource ('Get system status') with an explicit enumeration of the returned metrics (CPU, memory, uptime) scoped to a single device. This partially distinguishes it from broader siblings like get_device_details, though it never names that alternative outright.

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: an agent can infer this is the tool for point-in-time health metrics of one device. There is no explicit statement of when to prefer it over get_device_details, get_cloudx_status, or the many other per-device status tools in the sibling list.

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