busybar_get_status

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

readOnlyHint=true already establishes the safety profile, so the description's added value is the disclosure of what data comes back: connection, active app, device, power, uptime, firmware and update status. Since there is no output schema, this enumeration of returned categories is the main behavioral signal, and it is genuinely useful; it stops short of describing format, units, or whether values can be stale.

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 no filler, and the enumerated list is the most scannable form for a status snapshot. Every word maps to a reported data category.

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 zero-parameter, read-only status tool with no output schema, listing the reported categories is sufficient for an agent to decide to call it. The remaining gap is modest: no indication of response shape or whether the call is cheap enough to poll frequently.

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?

The tool takes zero parameters, so there is no parameter semantics to explain and the baseline applies. Nothing in the description misleads about inputs, and it correctly implies a no-argument, single-shot read.

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?

Uses a specific verb ('Read') and enumerates the concrete resources it reports: WM connection, active app, device, power, uptime, firmware and update status. That is far more specific than the bare name, though it never explicitly contrasts itself with near-siblings such as busybar_get_connectivity or busybar_list_apps, which an agent must infer from their names.

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 explicit when-to-use statement, no prerequisites, and no named alternative. An agent can infer this is the general 'what is the current state' call, but nothing tells it when to prefer busybar_get_connectivity or busybar_list_apps for narrower questions.

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