update_screen_group_playlist_item

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

No annotations are provided, so the description must carry the full behavioral burden. It states 'partially update' but does not explain what 'partial' entails—whether only provided fields are updated, how nested objects are merged, or the idempotency of the operation. Missing details on permissions, side effects, and error cases.

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 concise (single sentence, no fluff), but it is under-specified. Conciseness is achieved at the expense of necessary detail. A minimal viable description could still include usage context.

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?

Despite having an output schema and nested objects, the description does not help the agent understand input requirements or behavior. It omits information on valid fields for 'changes,' update semantics, and interaction with sibling tools. For a tool with 3 required params and no schema coverage, this is insufficient.

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 0% and the description adds no parameter-level information. The 'changes' parameter is an open object with additionalProperties: true, but the description gives no hints about valid fields or structure. The agent has no guidance beyond parameter names.

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 states 'Partially update one screen group playlist item,' which clearly specifies the verb (update), resource (screen group playlist item), and scope (partially, indicating patch behavior). It distinguishes from sibling tools like 'add_screen_group_playlist_items' and 'update_screen_playlist_item' by specifying the resource type.

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 does not mention prerequisites, conditions, or scenarios where other tools (e.g., 'add_screen_group_playlist_items') would be more appropriate.

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