apply_list_update

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

Since there are no annotations, the description must disclose behavioral traits, but it only states 'apply', implying a mutation without any details on side effects, reversibility, permissions, or the fate of the preview. This is a significant transparency gap for a commit operation.

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 sentence that is concise and front-loaded. Every word earns its place; there is no fluff or redundancy.

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 output schema and sparse annotations, this description is too thin. It fails to mention return values, preconditions, or what exactly happens when the update is applied, leaving the agent without sufficient context to invoke it confidently.

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?

The description adds minimal meaning to the single parameter 'previewId' by indicating it refers to a previously previewed update. However, it doesn't explain how to obtain it or what its format implies beyond the schema's minLength constraint. For a simple one-parameter tool, this is adequate but not enriching.

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 action (apply) and the resource (a previously previewed list update), which distinguishes it from sibling tools like apply_item_update or apply_column_update. It is specific and unambiguous, though it doesn't elaborate on what a 'list update' includes.

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 is given on when to use this tool versus alternatives. It doesn't mention that the previewId comes from preview_list_update, nor does it exclude using it for other entity updates. There is no context for when this tool is appropriate.

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