load_preset

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

No annotations are present, and the description only states the intended effect. It does not disclose side effects, error conditions, idempotency, or what happens if the player or preset is invalid.

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 free of unnecessary words, while still conveying the primary purpose and pointing to a related tool.

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, but the player parameter is essential and unexplained. Without knowing how to specify the player, an agent may not be able to invoke the tool correctly.

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?

preset_id is explained as numeric, but player is left completely undefined. The schema provides only types, so the description does not clarify whether player is a name, UUID, or other identifier.

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?

Clearly states the action ('Start playing') and the target resource ('a preset by its numeric id'). It also references list_presets() to distinguish from the listing tool.

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?

Provides some guidance by pointing to list_presets() for obtaining the preset id, but does not explicitly contrast with the sibling 'play' tool or specify when loading a preset is preferred.

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