playlist_collaboration_report

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

No annotations are present, so the description carries the behavioral disclosure burden. It signals a read-only 'Report' operation and names output facets (counts, timestamps, most-active), which is useful. It does not mention whether the playlist must be collaborative, side-effects, or behavior on empty/non-collaborative playlists.

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?

One concise sentence that front-loads the purpose and packs the key output dimensions into a parenthetical. There is no filler, no repetition of schema fields, and every word contributes to the call decision.

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 a single required parameter, no output schema, and no annotations, the description is largely self-sufficient: it identifies what to call with and what kind of report to expect. It leaves some ambiguity around exact return shape and non-collaborative edge cases, but those are minor for a simple reporting tool.

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 coverage is 100% and the single parameter playlist_id has a description ('Playlist ID'). The tool description adds no additional format, source, or validation guidance for that parameter, so it does not enhance what the schema already provides.

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 clear verb ('Report') and names the resource ('playlist') with a specific scope: who added what, counts, first/last timestamps, and most-active contributor. It is distinctive enough to separate it from general playlist getters, although it does not explicitly contrast with similar siblings like get_playlist_added_dates or collab_density_report.

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 a use case — auditing playlist collaboration contributions — but provides no explicit when-to-use guidance or exclusions. An agent is not told to prefer this over related siblings such as get_playlist_added_dates or playlist_collab_toggle when only certain details are needed.

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