shuffle_state_report

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

With no annotations provided, the description carries the full behavioral burden. It explicitly states 'Read-only,' disclosing non-mutating behavior, and specifies what dimensions the report covers (state, device, context). This provides meaningful transparency beyond the schema, though it does not mention edge cases such as no active playback.

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, tight sentence that front-loads the action and resource, then appends the 'Read-only' safety note. Every word adds value and no information is wasted.

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 low-complexity read-only tool with one optional parameter and no output schema, the description sufficiently conveys what the report contains and that the operation is safe. It does not fully specify edge cases like lack of active context, but the core semantics are complete enough for correct invocation.

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 the single response_format parameter is already fully documented with its enum values and meaning. The description does not need to repeat parameter details; the baseline of 3 applies because the schema does the heavy lifting.

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 uses a specific verb ('Report') and names the exact resource being inspected: current shuffle and repeat state, the device they apply to, and the active context. This clearly separates it from mutation siblings like set_shuffle, set_repeat, and repeat_queue_toggle, so an agent can tell what this tool does without opening the schema.

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 description makes the use case clear: call this when you need a read-only account of the current shuffle/repeat state and its device/context. It does not explicitly name alternatives or exclusion conditions, but the read-only framing and specific subject matter imply the appropriate context well.

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