validate_write

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

Annotations provide strong hints (readOnlyHint=true, idempotentHint=true, destructiveHint=false), so the description's additional behavioral context is minimal. It adds that validation uses 'optional fields_get metadata', but does not disclose what happens on validation failure or success beyond the implied read-only nature.

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 concise sentence, front-loading the verb. However, it sacrifices clarity for brevity, lacking structure and detail. Every phrase earns its place, but the lack of parameter or context information makes it merely adequate.

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 tool with 7 parameters and a validation purpose, the description is insufficient. It does not explain the validation logic, error behavior, or the role of output schema. The presence of an output schema reduces some burden, but the missing parameter descriptions and lack of usage context leave significant gaps.

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?

With 0% schema description coverage, the description must compensate for missing parameter explanations. It fails to elaborate on any of the 7 parameters (e.g., model, operation, values) beyond a vague reference to 'standard write payload' and 'optional fields_get metadata', leaving the agent without necessary semantic detail.

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 verb 'validate' and identifies the resource as a 'standard write payload' against 'fields_get metadata'. This distinguishes it from sibling tools like execute_approved_write or preview_write, but the term 'fields_get metadata' is ambiguous without additional context.

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 explicit guidance on when to use this tool versus alternatives such as preview_write or execute_method. The description does not mention prerequisites, when not to use it, or provide comparisons with other validation or execution tools.

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