playlists_create

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

No annotations are provided, so the description carries full burden. 'Create a new playlist' implies a write/mutation operation but doesn't disclose behavioral aspects like required permissions, whether the creation is immediate or queued, what happens on duplicate names, or what the response contains. For a mutation tool with zero annotation coverage, this is insufficient.

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 a single, efficient sentence with zero wasted words. It's appropriately sized for a simple creation tool and front-loads the essential information immediately.

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 mutation tool with no annotations and no output schema, the description is incomplete. It doesn't explain what happens after creation, potential error conditions, or behavioral constraints. Given the complexity of playlist management in this context (evident from sibling tools), more context about the creation operation is needed.

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%, with both parameters ('name' and 'type') documented in the schema. The description adds no additional parameter information beyond what's already in the structured schema. Baseline 3 is appropriate when the schema does the heavy lifting.

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 'Create a new playlist' clearly states the action (create) and resource (playlist), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'playlists_create_under' or 'playlists_set', which might have overlapping functionality in this playlist management context.

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. With many sibling tools for playlist operations (e.g., 'playlists_get', 'playlists_trigger', 'playlists_set'), there's no indication of prerequisites, appropriate contexts, or distinctions from similar creation tools.

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