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

Annotations already declare this is a non-read-only, non-destructive, closed-world operation. The description adds that the tool can complete or fail an export depending on the error input, but it does not explain side effects, idempotency, or what completion entails.

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 front-loaded sentence with no wasted text. The Widget-only constraint and the complete-or-fail behavior are both stated immediately.

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 three-parameter mutation tool with no output schema, the description covers the basic workflow stage and the error-failure path. It does not describe return behavior, result signals, or how assetId and exportId relate to the upload step, leaving gaps an agent would need to infer.

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 carry parameter meaning. It loosely connects the operation to a prior upload and mentions failing with an error, but it does not explain exportId or assetId semantics, leaving two of three parameters ambiguous.

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 a specific action pair: complete a browser-rendered export after upload, or fail it with an error. It also constrains the use case to Widget, distinguishing it from generic export tools. However, it does not name sibling tools or explicitly contrast itself with begin_local_export or upload_local_export.

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 implied usage context: it is Widget-only and applies after an upload has occurred. It also indicates the fail path via an error. It does not explicitly state when not to use the tool or name alternatives, so usage guidance is present but incomplete.

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