get_playlists

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

No annotations are provided, so the description carries the burden. It usefully discloses the default behavior ('Omit limit to fetch all of them') and implies a read-only operation with 'List'. However, it does not mention auth requirements, pagination behavior, or what happens when limit is explicitly provided.

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?

Two short sentences with no filler. The core purpose is front-loaded and the second sentence adds necessary parameter nuance without redundancy.

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 low-complexity read-only list tool with an output schema and a single optional parameter, the description is nearly complete. It covers the key behavior and default, though it omits minor details like permission requirements and limit edge cases.

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 adds real value by explaining that omitting limit fetches all playlists. This conveys the parameter's purpose and default semantics beyond the bare schema type and default value.

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 specific verb ('List') and a clear resource ('the current user's playlists'), which distinguishes it from siblings like get_playlist_tracks or create_playlist. The scope is unambiguous even without naming alternatives.

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?

There is no explicit guidance on when to use this tool versus alternatives such as get_playlist_tracks or create_playlist. The phrase 'current user's playlists' gives context, but no exclusions, prerequisites, or route-to-sibling instructions are provided.

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