playlist_details

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Playlist Details' gives no indication of whether this is a read-only operation, what data it returns, whether it requires authentication, or any rate limits. The description fails to provide any behavioral context beyond the vague name.

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?

While technically concise with just two words, this is a case of under-specification rather than effective brevity. The description fails to convey essential information about the tool's purpose or usage, making it inefficient despite its short length.

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 tool with 3 parameters, no annotations, and no output schema, the description 'Playlist Details' is completely inadequate. It doesn't explain what the tool does, when to use it, what behavior to expect, or what information will be returned, leaving critical gaps in understanding.

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 100%, so the schema already documents all three parameters (id, hl, gl) with basic descriptions. The description adds no additional meaning about parameter usage, relationships, or examples beyond what the schema provides, meeting the baseline for high schema coverage.

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 'Playlist Details' is a tautology that merely restates the tool name without specifying what action the tool performs. It doesn't indicate whether this retrieves, displays, analyzes, or modifies playlist details, nor does it distinguish this tool from sibling tools like 'playlist_videos' or 'channel_playlists'.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention any specific context, prerequisites, or comparisons to sibling tools like 'playlist_videos' (which might show videos within playlists) or 'channel_playlists' (which might list playlists by channel).

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