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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the mode behavior that omitting state lists choices, but it does not disclose return format, permissions, or other operational details. There is no contradiction with annotations.

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?

The description is two sentences, front-loaded with the two main modes, and contains no redundant wording. Every sentence contributes to understanding the tool's purpose and the state-omission behavior.

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?

The tool has a nested state object with nine cryptic fields, a required storefront parameter, and no output schema. The description explains the two modes but does not explain the return shape or map the state fields, leaving significant gaps for correct invocation.

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%, and the nested state object uses cryptic keys such as hc, pre, s, cvr, mnt, rc, enc, and gst. The description names several domain concepts like housing, preset, socket, covers, mount, and quantity, but it does not map them to the parameter keys or explain storefront, rc, enc, or gst.

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 specific verbs and resources: inspect native PureLink mediahub2 choices or resolve a housing, preset, socket, covers, mount and quantity into a bill of materials. It clearly distinguishes two operating modes, though it does not explicitly differentiate itself from sibling tools such as configure_power or describe_power_selector.

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?

It explicitly says to omit state to list choices, which implies that providing state resolves a bill of materials. However, it gives no guidance on when to use this tool versus siblings, no prerequisites, and no exclusions.

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