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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description is consistent with that by explicitly stating it 'opens nothing by itself' and that execution happens through the browser tools. That is meaningful disclosure of the two-phase workflow, which the annotations alone would not convey. It does not describe the shape of the returned steps (e.g., whether they are generic or playlist-specific).

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 core behavior is front-loaded in the first sentence and the execution handoff in the second, which is good structure. The third sentence about Spotify's official Web API and a Claude connector with dated checks ('since 23 Apr 2026, checked 5 Nov 2026') is irrelevant to invoking this tool and dilutes the definition, and 'from ChatGPT, Claude or any AI agent' is filler.

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 zero-parameter, no-output-schema tool, the description covers what is returned at a high level (step-by-step screens, buttons, fields) and the browser-tool handoff. It leaves a real gap: with no inputs, it never says whether the steps depend on which playlist/song the user has open, or what the agent should ensure is true in the Spotify session before following the steps.

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 tool takes zero parameters, so there is no parameter semantics to explain and the baseline is 4. The description adds no parameter-level meaning, but none is needed for an empty schema.

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 and resource ('Remove songs from playlist in the user's own Spotify account') and scopes it to the user's own account, which distinguishes it from read/search siblings. It also clarifies that the tool does not perform the removal itself but 'Returns how to do it in Spotify step by step', resolving the tension with the name. The mixed framing (a removal-sounding name for a guidance tool) keeps it from a 5.

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?

It gives a follow-up path: after getting the steps, 'do it with the cotlet_browser_* tools in the user's Spotify Cloud Browser', which tells the agent what to do next. However, it never states when to prefer this over siblings like spotify_read_playlist_songs or when not to use it, and the API/connector remark is not actionable routing guidance.

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