playlists_create

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

No annotations provided, so description carries full burden. It states 'Create' without disclosing side effects (e.g., permissions needed, whether duplicates are allowed, or if existing playlists are modified). Minimal behavioral info.

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?

Single sentence, no wasted words. However, it sacrifices useful context for brevity. Appropriate length for a simple operation but could be slightly expanded.

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?

Adequate for a basic create tool with fully described parameters and no output schema. However, lacks context about parent-child relationships with 'playlists_create_under', and no mention of return value (e.g., playlist ID).

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%, with both 'name' and 'type' already described in the schema. The description does not add meaning beyond what's in the schema, so baseline score of 3 applies.

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?

Description clearly states verb ('Create') and resource ('new playlist'). However, it does not differentiate from sibling tool 'playlists_create_under', which likely creates a playlist under a group. The name implies top-level creation, but description misses this nuance.

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?

No guidance on when to use this tool versus alternatives like 'playlists_create_under' or other playlist manipulation tools. Missing prerequisites or context (e.g., 'Use this for top-level playlists only').

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