Get a TIDAL v2 mix

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

Annotations declare readOnlyHint=true and openWorldHint=true, so the agent knows this is a safe read operation that may interact with external state. The description adds that it returns 'public metadata', clarifying the read-only, non-privileged nature, but doesn't disclose error behavior, rate limits, or what 'public metadata' includes. With annotations covering the safety profile, this is adequate but not rich.

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, concise sentence that front-loads the core purpose ('Return public metadata for one exact current-generation mix ID'). Every word earns its place, with no redundancy or fluff.

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 has an output schema, so the description needn't explain return values. However, it provides no guidance on usage relative to siblings, no details on parameter semantics, and no behavioral context beyond annotations. For a simple read operation with one required parameter, this is minimally viable but leaves gaps that could lead to misuse or confusion with the similarly named tidal_get_mix.

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%, meaning the single parameter 'mix_id' has no description in the schema. The description mentions 'one exact current-generation mix ID', which clarifies that the parameter expects a specific ID string for a current-generation mix, adding some semantic value. However, it doesn't specify format, source, or constraints beyond the schema's basic type and length limits. A baseline of 3 is appropriate given the minimal but nonzero compensation.

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 states a specific verb ('Return') and resource ('public metadata for one exact current-generation mix ID'), making the purpose clear. It distinguishes itself from siblings like tidal_get_mix and tidal_get_mix_image by emphasizing 'public metadata' and 'current-generation', though it could explicitly note its relationship to the v1 mix tool. The use of 'v2' in the name and 'current-generation' in the description provides some differentiation.

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 explicit guidance on when to use this tool versus alternatives such as tidal_get_mix, tidal_get_mix_v2_image, or tidal_list_favorite_mixes. The description implies it's for fetching mix metadata by ID, but doesn't state prerequisites or when another tool would be more appropriate. This leaves the agent to infer usage from the tool name and sibling names alone.

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