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

No annotations are provided, so the description carries the full burden. While 'Reorder' implies a mutation, the description fails to disclose whether this is permanent, reversible, idempotent, or what happens to the original playlist order. Critical safety information for a write operation is missing.

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, efficient sentence that front-loads the action and immediately lists the strategy options. Every word earns its place with zero redundancy.

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 presence of an output schema, the description appropriately omits return value details. However, for a mutation tool with zero annotations, it lacks essential behavioral context about persistence and reversibility, leaving the agent under-informed about side effects.

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?

With 0% schema description coverage, the description compensates effectively by enumerating the valid strategy values (variety, alphabetical_artist, etc.). This provides crucial constraint information missing from the schema, though it does not explain what each strategy algorithm actually does.

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 clearly states the action ('Reorder a playlist') and resource, and lists the specific strategy options available. However, it does not explicitly differentiate from sibling tools like 'spotify_reorder_playlist' or 'spotify_sort_playlist', leaving the agent to infer that 'smart strategy' implies algorithmic sorting.

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 guidance on when to use this tool versus similar alternatives (spotify_reorder_playlist, spotify_sort_playlist), nor any mention of prerequisites or constraints. The agent cannot determine if this should be used for manual reordering vs. algorithmic shuffling.

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