set_volume

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

With no annotations provided, the description must carry the behavioral burden, but it omits key side effects such as the mute parameter, potential errors, or idempotency. The statement about calling with no arguments directly conflicts with the schema, further reducing transparency.

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 brief and mostly to the point, but the inclusion of the inaccurate 'no arguments' clause adds unnecessary confusion. A clearer structure that explicitly distinguishes read vs. set operations would improve it without adding length.

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 tool with four parameters and no annotations, the description is incomplete. It omits the mute behavior, does not clarify the relationship between level and volume, and fails to mention the requirement for player, leaving the agent with ambiguous operational context.

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?

The description explains tell_followers and implies player through context, but leaves level and mute completely unaddressed. Given the schema provides no descriptions, the description fails to compensate for the majority of parameters, making it hard to know which parameter maps to which behavior.

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 clearly states the tool gets or sets a player's volume with a 0-100 range, but is undermined by the contradictory phrase 'Call with no arguments' given that 'player' is a required parameter. The core purpose is evident but muddled by this inconsistency.

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?

It provides conditional usage guidance for reading vs. setting volume and explains tell_followers for grouped players. However, it does not mention when to prefer this over sibling tools like get_status, nor does it address the required player parameter in the usage context.

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