halo_dashboard

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

Annotations are empty, so the description carries the full burden. It does disclose the return format and the structure of the app field, and the example shows a simple awaited call. However, it does not explicitly state that the call is read-only/non-destructive, nor does it mention error behavior or authentication needs. For a status dashboard this is a moderate but not severe gap.

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 short, well-structured with Return Format and Examples sections, and front-loads the core purpose in the first line. Every sentence contributes useful information and there is no filler.

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 parameterless status tool, the description covers the outcome and a usage example, and an output schema exists to supplement return-value details. The main missing piece is usage context relative to the sibling tools, but that is already accounted for in the usage dimension. Overall it is sufficiently complete to invoke correctly.

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 has zero parameters and the schema trivially covers 100% of its (empty) parameter set. With no parameters to explain, the description needs to provide no parameter semantics; the baseline of 4 applies.

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 identifies a status dashboard for Halo and specifies the return shape ({success, message, app}) plus what the app carries (device, battery, display, counts). This is clear enough to indicate its function, though it lacks an explicit verb like 'get' or 'retrieve'. Its role as an overview is implied relative to the sibling tools, but not explicitly differentiated.

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?

No guidance is given for when to use halo_dashboard versus halo_device, halo_help, or halo_shutdown. The name suggests an overview vs. device-specific tool, but the description never states this distinction or any exclusions. An agent must infer usage from the sibling names.

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