Behavior2/5

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It implies reconnection is idempotent and recovery-oriented, but does not explain side effects, prerequisites, failure behavior, or whether the operation disconnects before reconnecting.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that communicates the action and the trigger condition with no filler. Every part earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity tool with an output schema, the description is mostly adequate: it says what the tool does and when to use it. However, it leaves the optional device parameter's default behavior and the meaning of 'Portal' unexplained, so an agent may still be uncertain on some edge cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description only says 'for a device,' which adds minimal meaning beyond the parameter name. It does not explain what the device value should be, what null/default means, or what happens when the parameter is omitted.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action: (re)connecting adb and the Portal for a device, which distinguishes it from diagnostic siblings like ping_device or get_device_status. The term 'Portal' is somewhat domain-specific and unexplained, but the core verb and resource are clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives a clear usage condition: use it after the network path has recovered. It does not mention alternative tools or explicit when-not-to-use cases, but the recovery context is enough to guide selection.

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