TDQS

A3.8/5.0
Behavior3/5

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

With no annotations, the description carries the behavioral burden. 'Returns' implies a read-only operation and 'connected Android device' implies a prerequisite, but it does not state side effects, output format, or failure behavior if no device is connected. It is minimally transparent but not rich.

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?

A single sentence that states the action, the resource, and the invocation requirement without any filler. The key information is front-loaded and every word is useful.

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

Completeness4/5

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

For a zero-parameter read-only tool with no output schema, the description is mostly complete: it identifies the resource and the target device. It could add the exact return shape or error conditions, but for such a simple tool the current coverage is adequate.

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

Parameters4/5

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

There are zero parameters and the schema is an empty object with 100% coverage. The description confirms 'No parameters are required,' which adds a small amount of guidance beyond the schema and earns the zero-parameter baseline.

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

Purpose5/5

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

The description names a specific verb ('Returns'), a specific resource ('device overlay configuration properties'), and a clear target ('the connected Android device'). It is distinct from sibling tools like get_properties or get_battery_level, which are more generic or target different data.

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?

The description says no parameters are required, which helps invocation, but it gives no guidance on when to choose this tool over siblings or when not to use it. There are no exclusions, alternatives, or context cues beyond the tool's own behavior.

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