Streaming quality

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

Annotations already flag destructiveHint=true and idempotentHint=false, but the description adds real context: the change is transcoded in the background (async), and 999/1000 map to original MP3 and lossless. It doesn't state reversibility or whether the original is preserved, leaving a small gap.

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?

Three tight sentences that lead with the resource and then the value semantics. No filler, though the sentence structure is slightly dense.

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?

No output schema exists, and the description only loosely describes the return ('the current state'), but it fully covers input semantics and the async transcoding behavior. Adequate for an agent to call it correctly, with a minor gap on return format.

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 67% and `value` has no schema description, but the description explains best, numeric bitrate, 999, and 1000 meanings. `track` and `author` are already documented in the schema, so the description compensates where it matters most.

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 the resource (streaming quality of an own track) and describes both the read (no value = current state) and write (value = queue quality) behaviors. No verb heads the sentence, but the dual behavior is clear. No sibling deals with streaming quality, so differentiation isn't needed.

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?

Clearly tells the agent when to omit value (read current state) versus when to supply one (queue a change). No exclusions or alternatives are named, but no sibling overlaps this capability.

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