Power consumption and supplies

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

Annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=false, so the safe-read profile is covered structurally. The description contributes the data inventory (consumption stats, cap, per-supply model/capacity/voltage/firmware/health, redundancy), which is useful payload context but not behavioral. It doesn't note iDRAC-version variability, latency, or whether data is live vs. cached, which for a controller-status call would matter.

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?

One dense, front-loaded sentence with no filler; the parenthetical attribute list is efficient. Slightly list-heavy, but every clause maps to returned data.

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, the description does the important work of enumerating the returned fields, so an agent knows what it will get back. Combined with annotations and a fully documented optional parameter, only the version-dependence of the voltage sensors is left implicit.

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 single parameter's own description already explains the iDRAC 8 power-good nuance. The description adds only 'Optionally the voltage sensors,' essentially restating the flag. Baseline 3 is correct when the schema fully carries parameter meaning.

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 enumerates exactly what the tool returns: current/average/minimum/peak power consumption, power cap, power supplies with their attributes, and optional voltage sensors. That is specific enough to separate it from siblings like idrac_thermal or idrac_health. It lacks an explicit verb ('get/read'), but the resource scope 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?

Usage is only implied by the content: an agent can infer it should call this when it needs power draw or PSU data. There is no explicit statement of when to prefer it over idrac_thermal (temperature) or idrac_health, and no exclusion or prerequisite guidance.

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