Count playlist tracks

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds a useful nuance by promising the 'exact' count of 'audio tracks' (suggesting videos are excluded), but gives no note on auth or empty/private playlist behavior.

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?

A single front-loaded sentence with no filler; the operation and its result are stated immediately.

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?

An output schema exists, so return values need no explanation, and the tool is simple. However, with no annotation-independent guidance and an undocumented required parameter, the definition is only minimally complete for correct invocation.

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?

There is a single required playlist_id with 0% schema description coverage, so the description would need to carry the burden of explaining the identifier. It says nothing about playlist_id format or where to obtain it, leaving the parameter effectively undocumented.

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?

States a specific verb (Return) and resource (number of audio tracks in a playlist), which cleanly signals a count-retrieval operation. It stops short of explicitly distinguishing itself from near-neighbors like tidal_get_playlist_item_count or tidal_get_playlist_tracks, though the word 'audio' implies a scope difference.

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?

No guidance on when to choose this over tidal_get_playlist_item_count or tidal_get_playlist_tracks, and no prerequisites. The agent is left to infer selection from the name alone.

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