preview_view_formatting_update

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

With no annotations provided, the description bears full responsibility for disclosing behavior. It does not explain that previewing is non-destructive, what the preview output looks like, or any side effects. The verb 'preview' implies no mutation, but this is neither stated nor elaborated.

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 short, which is concise, but it is under-specified to the point of being nearly meaningless. Like the 'Process' calibration example, this is not efficient conciseness but deficiency of content.

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 the complexity of the parameter structure (3 required params, 0% schema coverage, no output schema, no annotations), the description is grossly inadequate. It leaves all essential context—what the preview returns, expected input semantics, and relationship to apply tools—unspecified.

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%, so the description must compensate. It merely hints that formatting involves JSON but does not clarify the meaning of listId, viewId, or the 'formatting' parameter's possible string/object forms. No parameter is explained beyond schema type constraints.

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 'Preview updating view JSON formatting' is essentially a restatement of the tool name, adding only the vague term 'JSON'. It does not specify the resource scope (listId/viewId) or the precise action (previewing a formatting change) unambiguously. It does not distinguish from sibling tools like 'preview_view_update' or 'apply_view_formatting_update'.

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?

There is no guidance on when to use this tool versus alternatives, such as when to preview versus apply formatting updates. No prerequisites or exclusions are mentioned, leaving the agent without context for tool selection.

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