update_playlist

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

With no annotations, the description carries full burden. It states 'Update' but does not disclose side effects (e.g., propagation to followers), required permissions, reversibility, or what happens when optional parameters are omitted. The output schema exists but is not described.

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 extremely concise with a single purpose sentence followed by a structured parameter list. Every line adds value with no waste.

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?

The description covers the main updateable fields but lacks details on behavior when parameters are omitted, error scenarios, and output format. Given the presence of an output schema, the missing return value explanation is partially mitigated.

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 0%, so the description's Args list provides needed semantics (e.g., 'New name', 'Whether the playlist should be public'). However, it doesn't clarify that parameters are optional/nullable or any constraints like name length limits.

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 clearly states the tool updates a playlist's name, description, or visibility. It uses a specific verb ('Update') and resource, and distinguishes from sibling tools like create_playlist, get_playlist, and item manipulation tools.

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, such as when to update playlist metadata vs using other playlist manipulation tools. No prerequisites or exclusions are mentioned.

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