Play Native Routine Behavior

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It only says 'Trigger native routine behaviors' without explaining what triggering means in practice, e.g., that audio plays on the Echo device, that the device must be online, or what the response/result contains. 'Trigger' is too vague to be transparent.

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?

One sentence with a clear verb-object structure, followed by a compact list of representative examples. No filler or repetition of schema fields; the description is easy to scan and front-loaded.

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?

The tool is simple, with only two required parameters and a fully described enum, so an agent can likely construct a valid call. However, there is no information about expected outcomes, side effects, or how this differs from sibling tools like alexa_execute_routine, making the overall context incomplete.

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 coverage is 100% and serialNumber already points the agent to alexa_list_devices stub. The description adds human-readable meaning to the enum values by mapping them to everyday examples like stories, jokes, and fun facts, which helps disambiguate terse enum strings such as 'tellstory' or 'flashbriefing'.

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 uses a specific verb ('Trigger') and a specific resource ('native routine behaviors'), then clarifies with concrete examples like weather report, traffic, and flash briefing. It is clearly distinct from 'speak' or 'play music' tools, though it never explicitly contrasts with alexa_execute_routine, leaving some ambiguity between native and custom routines.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no alternatives are named. Given the large sibling list, an agent cannot tell from the description whether to pick this tool or alexa_execute_routine for a particular request; the only signal is the word 'native'.

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