update_playlist

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

No annotations are provided, so description carries full burden. Merely states 'update' without disclosing side effects, authentication needs, rate limits, or what happens to unchanged fields. Minimal disclosure for a mutation tool.

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?

Extremely concise single-phrase description with no waste. Could be slightly more structured (e.g., specifying required parameter), but earns its brevity.

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?

Given no annotations, no output schema, and 3 params with 0% schema coverage, the description omits return value, side effects, and prerequisites. Incomplete for a mutation tool that modifies state.

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 description must compensate. It adds meaning by linking title and description parameters to their roles, but does not explain playlist_id purpose or provide constraints (e.g., allowed characters, length). Insufficient detail for zero-coverage schema.

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 explicitly states 'Update playlist title/description', clearly identifying the verb (update), resource (playlist), and specific fields (title, description). It distinguishes from siblings like create_playlist, delete_playlist.

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?

Implies usage for updating existing playlist's title/description, but no explicit guidance on when to use versus alternatives (e.g., delete and recreate) or when not to use. Lacks exclusions or prerequisites.

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