watchface_get_local

Retrieve local clock information from a Divoom device by current or explicit clock ID; for AstroToo, check hardware capabilities first and use its 480x480 resources.

Instructions

Call Device/GetLocalClockInfo for current or explicit clock id. For AstroToo, first query hardware/capabilities; use the 480x480 AstroToo resources. Legacy 800x1280 examples and typography apply only to TimesFrame.

TDQS

C2.7/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full behavioral burden. It adds useful non-obvious context about AstroToo requiring a hardware/capabilities query and TimesFrame-specific legacy resources, but it does not explicitly confirm read-only behavior, describe authentication needs, or state what is returned.

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

Conciseness4/5

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

The description is concise and front-loads the main operation before adding platform-specific caveats. The device-specific details are specialized but relevant, and there is little wasted wording.

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

Completeness2/5

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

For a 5-parameter tool with no annotations, low schema coverage, and no output schema, the description is too thin. It provides platform caveats but does not explain return values, parameter behavior, or enough mutation/read semantics for an agent to call it confidently.

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 only 20%, so the description must compensate. It mentions current or explicit clock id, loosely mapping to clockId/useCurrentDisplayClock, but adds no meaning for parentItemId, parentClockId, or the distinction between them, and leaves most top-level parameters undocumented.

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

Purpose3/5

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

The description references the underlying API endpoint Device/GetLocalClockInfo and mentions current or explicit clock id, implying retrieval of local clock information. However, it does not plainly state the user-facing outcome and relies on the reader understanding the internal endpoint name, leaving the purpose somewhat vague relative to siblings like watchface_get_device_info.

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

Usage Guidelines2/5

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

It provides platform-specific prerequisites for AstroToo and resource guidance for TimesFrame, but does not say when to use this tool versus alternatives such as watchface_get_device_info or watchface_list_devices. There is no explicit when-to-use or when-not-to-use guidance.

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