Create a private multi-seed radio playlist

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

Annotations already communicate that this is a non-read-only, non-idempotent, non-destructive operation. The description adds useful context by specifying that the playlist is private and the mix is 'fresh,' but it does not go beyond that into auth requirements, rate limits, or side effects.

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 sentence with no filler and puts the core purpose first. It is concise, though it is also somewhat under-specified rather than fully informative.

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?

Even though an output schema exists and annotations cover basic safety, the description omits important constraints such as the lower/upper seed bounds, the limit default, and how this creation flow behaves after invocation. The tool could be called incorrectly because key behavioral details are left to inference.

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%, so the description carries the burden of explaining parameters. It only hints at the seed-count range for queries and does not address title, description, or limit. The 'two-to-ten-seed' constraint is useful but not tied explicitly to the queries parameter.

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 action and resource: 'Create one private playlist from a fresh two-to-ten-seed radio mix.' This clearly distinguishes it from sibling read-style tools like get_multi_seed_radio and search_songs, and from the likely single-seed variant create_private_radio_playlist.

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 phrase 'two-to-ten-seed radio mix' implies the tool is for creating a playlist from multiple seeds, but it never explicitly says when to use this tool versus create_private_radio_playlist or get_multi_seed_radio. No exclusions or alternative routing are provided.

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