Unlike Tracks

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

The annotations already carry the key behavioral signals: destructiveHint=true, readOnlyHint=false, and idempotentHint=true. The description adds only a capacity constraint ('up to 50') and otherwise relies on the operation name and annotations. It does not contradict the annotations, but it does not deepen behavioral understanding much beyond them.

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 extremely compact: one purpose sentence plus a one-line Args entry. Every word adds value, and the most important scoping information ('saved (liked) tracks') is front-loaded. No filler or repetition of schema details.

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?

For a simple one-parameter, output-schema-bearing tool with annotations covering destructive and idempotent behavior, the description is nearly complete. It covers the target resource and the important parameter limit. A small gap is the absence of any guidance distinguishing this from playlist-removal operations, but that is not critical to calling it correctly.

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 description coverage is 0%, so the description carries the burden for explaining track_ids. It adds meaningful semantics: values can be Track IDs or URIs, and at most 50 are accepted. This is useful, though it stops short of giving exact URI formats or examples, so it is not a perfect compensation.

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 names a specific verb ('Remove') and a precise resource ('the user's saved (liked) tracks'), which clearly distinguishes this tool from siblings like remove_tracks_from_playlist. The title 'Unlike Tracks' reinforces the intent. An agent can immediately tell what this tool does.

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 operation itself implies when to use it: whenever tracks need to be removed from the saved/liked library. However, it does not explicitly contrast it with alternatives such as remove_tracks_from_playlist or note when not to use it. Usage guidance is present by implication, not by explicit direction.

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