play_sound_file

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

Annotations are all false and provide no useful safety profile. The description only restates the basic play action and does not disclose whether playback blocks, repeats indefinitely with loop, or requires stop_sound to halt.

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 concise sentence with the key action front-loaded. It is appropriately sized for a simple tool, though it omits important loop and stopping details.

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 sound-playing tool with no output schema and unhelpful annotations, the definition should explain loop behavior, what happens when the file is missing, and how to stop playback. None of that is present.

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 0%, and the description does not explain the name format or the semantics of the loop flag. The schema only provides basic types and defaults, so the description adds no parameter-level meaning.

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 names a specific verb and resource: play an existing .rso sound file stored on the NXT. This clearly distinguishes it from siblings like play_tone and stop_sound.

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 phrase 'existing .rso sound file stored on the NXT' implies the file must already be present and hints at the alternative of using play_tone for tones, but 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.
