Set Spoken Reminder

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the scheduling intent and does not mention side effects, whether an existing reminder is overwritten, device availability requirements, confirmation behavior, or timezone handling. For an action tool this is a meaningful 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?

One sentence of roughly ten words, no redundancy, and it front-loads the core purpose. It does not waste space repeating details already present in the schema.

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 simple three-parameter action, the description plus schema covers the basics of what to pass. However, with no output schema and no annotations, the agent is left without guidance on expected confirmation, failure modes, or how this differs from the many sibling speech tools, so completeness is only adequate.

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 100%, so all three parameters are already documented with types and examples. The tool description adds no new parameter-level context beyond calling the timestamp 'specific time' and the serial number an Echo device, so it stays at baseline.

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 specific verb ('schedule'), resource ('spoken reminder'), target ('Echo device'), and timing constraint ('specific time'). This clearly distinguishes it from siblings like alexa_announce or alexa_text_command, which target immediate announcements or commands.

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 use case is implied: use this tool when the agent needs a one-time spoken reminder at a set time. However, it never states when not to use it or names alternatives such as alexa_announce for immediate broadcasts or alexa_text_command for commands, so the agent must infer routing.

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