get_most_played_tracks

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. However, it only restates the tool's purpose and the limit parameter, without adding context such as how 'most played' is defined, ordering of results, or whether unplayed tracks are excluded. This is minimal additional value beyond the name.

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 brief and front-loaded with the purpose, followed by a clear Args section and Returns section. Every sentence provides necessary information, and there is no redundant or filler content.

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 simplicity (one optional parameter, no annotations, and presence of an output schema), the description adequately covers the core function and parameter semantics. It lacks explicit usage guidance and behavioral details, but those are less critical for a straightforward read-only list operation, and the output schema likely documents return values.

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?

The input schema has one parameter 'limit' with zero description coverage, but the description adds crucial semantics: 'Maximum number of tracks to return.' This clarifies the parameter's role and compensates for the schema's lack of explanation.

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 uses a specific verb+resource structure ('Get the most played tracks in the library') and clearly distinguishes itself from sibling tools like get_top_rated_tracks or get_unplayed_tracks by focusing on play counts. The scope 'in the library' adds further clarity.

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 description implies the tool should be used when the most played tracks are needed, but it does not explicitly mention when to use it over alternatives or provide any exclusions. Sibling tools with similar purposes (e.g., get_top_rated_tracks) are not referenced or differentiated.

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