add_tracks_to_playlist

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

No annotations are provided, so the description must cover behavioral traits. It clarifies that duplicates are handled based on the allow_duplicates flag, but it does not mention error conditions (e.g., invalid playlist_id, authentication requirements) or confirm that it is a write operation. More detail would improve transparency.

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 front-loaded with purpose and includes structured sections (usage, parameters, results). However, it is slightly verbose, especially the processing instructions that could be condensed or moved to an output schema.

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 no output schema, the description adequately describes the return value (dictionary with status and count). It covers the main behaviors but lacks details on error responses and edge cases, which would enhance completeness for an AI agent.

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 explains each parameter: playlist_id (required, obtainable via get_user_playlists), track_ids (list of TIDAL track IDs), and allow_duplicates (behavior when false). It adds context beyond the schema, though it could specify that track_ids items must be strings.

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 begins with a clear statement of the tool's function: 'Adds tracks to an existing TIDAL playlist.' It uses a specific verb ('adds') and resource ('existing TIDAL playlist'), and the purpose is distinct from sibling tools like create_tidal_playlist or delete_tidal_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?

Explicitly lists example user requests that should trigger this tool ('Add this song to my playlist', etc.) and implies when not to use it (when the playlist does not already exist). This provides clear decision guidance.

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