set_shuffle

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

No annotations are provided, so the description carries the full behavioral burden. It conveys that the operation is a bidirectional toggle, but says nothing about whether the change persists across tracks/sessions, whether it affects the current queue or only future playback, or whether it requires an active playback context.

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?

A single short sentence with no filler and the key concept front-loaded. It is efficient, though it leans on the reader's assumption that shuffle is a playback modifier.

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?

An output schema exists, so return values need no explanation, and the tool has only one required parameter. Still, for a state-mutating playback tool with no annotations, the description leaves persistence scope and preconditions unstated.

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 0% for the single boolean parameter, so the description must compensate. It does map the parameter to an on/off concept (activar/desactivar), but never states which boolean value selects which state, leaving the mapping to be guessed.

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?

States a specific verb pair (activates/deactivates) and resource (shuffle mode), so the agent knows exactly what is being toggled. It does not, however, differentiate itself from the sibling set_repeat, which has identical grammar and semantics.

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 when-to-use guidance, no prerequisite (e.g. whether playback must be active), and no mention of the nearest alternative, set_repeat. Usage must be inferred entirely from the tool name and the playback-control sibling group.

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