Get a track radio mix

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered, but the description adds essentially nothing beyond that: no note on whether the mix is stable/cacheable, what the returned mix contains, or any failure mode for an invalid track_id. 'Reusable' hints at stability but is not explained.

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, front-loaded with the verb and resource, with no wasted words. It is concise, though part of that brevity comes from omitting useful information rather than from good editing.

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-shape explanation is not required, and annotations cover the safety profile. Still, for a single-parameter read tool the description leaves the parameter undocumented and the sibling distinction unresolved, which is the minimum viable rather than complete.

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 0% and the single parameter track_id is documented nowhere. The description never mentions track_id, its format, or where to obtain it, so it fails to compensate for the coverage gap.

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 verb ('Return') and a resource ('the reusable mix that powers radio for one track'), but 'reusable mix' is ambiguous jargon and the definition never distinguishes this from the near-identical sibling tidal_get_track_radio, nor from tidal_get_mix/tidal_get_mix_v2. An agent can guess the intent but cannot confidently tell it apart from its neighbours.

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 at all. With siblings like tidal_get_track_radio, tidal_get_artist_radio_mix, tidal_get_mix and tidal_get_mix_v2 in the same namespace, the absence of any selection criteria is a real gap.

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