collab_mix_from_followed

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It openly discloses the request fan-out pattern, concurrency 5, artists_cap capping, per-artist track limits, round-robin merge strategy, dry_run default, and a quota formula. This is far more transparent than most tool descriptions.

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 dense but every clause carries necessary operational information: purpose, pipeline steps, concurrency, dry-run default, and quota. The main purpose is front-loaded and no words are wasted.

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?

Given the tool's complexity and the absence of an output schema, the description explains the algorithm and the dry-run plan concept well, and response_format partially covers return style. The main gap is that commit mode's actual return contract (e.g., created playlist URI/ID) is not stated, and auth/error behavior is absent.

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 100% with detailed parameter descriptions, so baseline is 3. The description adds operational meaning by showing how artists_cap and per_artist drive the algorithm and the resulting GET quota, and by explaining how dry_run controls whether any mutation happens.

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 opens with a specific verb and resource: 'Build a collaborative-style mix playlist from your FOLLOWED artists' recent releases.' It then details the full pipeline (followed-artists walk, album fan-out, round-robin merge), making the tool's unique role unmistakable even within a large sibling set.

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?

Usage context is implied rather than stated: an agent can infer it is for turning followed artists' recent releases into a playlist, but no alternative tools are named and no explicit 'use this when / not when' guidance is given. In a long sibling list with many music-generation tools, explicit routing would strengthen this dimension.

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