busybar_get_connectivity

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

The readOnlyHint annotation already establishes this is a safe read operation, and the description adds useful scope by naming which connectivity transports are inspected. However, it says nothing about freshness, caching, or error behavior when a transport is unavailable.

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 verb first and the resource set enumerated compactly. No filler, no repetition of the tool name or of annotation information.

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 tool with readOnlyHint coverage and no output schema, the description is nearly complete because it enumerates the status categories returned. It could still be stronger by noting the relationship to busybar_get_status or whether all transports are always reported.

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 document and the baseline is a 4. The description correctly implies no input is needed to retrieve the full connectivity snapshot.

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 uses a specific verb (Read) and enumerates the exact resources returned: Wi-Fi, Bluetooth Low Energy, and USB/Wi-Fi transport status. It does not distinguish this from the sibling busybar_get_status or explain the relationship to bar_connect, so sibling differentiation is missing.

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 instead of busybar_get_status, bar_status, or bar_connect. The agent must infer usage from the name alone, and no prerequisites or exclusions are stated.

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