new_music_from_saved_artists

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

No annotations are present, so the description carries the full burden. It adds a useful quota warning ('red followed-artist walk + per-artist album peeks') that flags a potentially expensive operation, but it does not state whether this is read-only, describe pagination/limits, failure modes, or any 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?

Two sentences with the main value proposition front-loaded and the quota warning cleanly appended at the end. No tautology, fluff, or repetition of schema details.

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 optional-param read tool, the core scope, sort order, optional saved-album inclusion, and quota warning are all present. The description adequately carries the return concept ('newest reases sorted by release date') since no output schema exists, though exact item types are left to response_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 describes 3 of 4 params; the description only gestures at include_saved_album_artists via 'optionally those in your saved albums'. max_results receives no semantic help from the description, but its numeric schema (max 2000) and the feed concept make it fairly obvious.

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?

Uses a specific verb/object construction: 'Newest reases across the artists you follow...' and brands it 'your personal new-release feed', which clearly separates it from generic feed/explorer siblings. The optional saved-albums clause adds precision.

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?

Implies use case — a personal new-release feed from followed artists — but never states when-not to use or names alternatives such as new_music_from_top_artists or artist_release_digest. An agent can infer the target use, but there is no explicit disambiguation.

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