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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only reveals the execution environment and the negative physical-device scope; it does not disclose whether files are mutated, how results are returned, whether network access is available, or any side effects of running tests.

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 a single, front-loaded sentence that communicates the core behavior and a clarifying constraint without filler. It is efficient, but the brevity leaves out useful detail that would improve the agent's understanding.

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?

Given three parameters, no output schema, and no annotations, the description is too sparse to allow confident invocation. It omits file path expectations, timeout behavior, the role of expect_logs, and return value or result format, leaving the agent to guess about important operational details.

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?

Schema description coverage is only 33% (timeout_ms), and the tool description mentions no parameters at all. The description does not explain what 'files' should contain, how 'expect_logs' is used, or the meaning of timeout beyond the schema's basic description. This is a significant gap for a tool with three parameters.

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 states a clear action ('Run') and resource ('BrightScript test files') and specifies the environment ('headless simulator') with an explicit contrast to a physical Roku device. This makes the tool's purpose reasonably distinct, though it does not name or differentiate from sibling tools directly.

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?

The description implies the tool is for headless simulator testing and explicitly says it is not for physical devices, which gives some contextual guidance. However, it does not state when to prefer this tool over siblings, nor does it mention any exclusions, prerequisites, or alternative tools.

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