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

Annotated as readOnlyHint=false, implying mutation, but the description adds that it is a 'multipart' upload completion, providing some behavioral context. However, it does not disclose idempotency, side effects (e.g., whether the item becomes immediately available), or error conditions beyond access issues.

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: four sentences, front-loaded with the core action, followed by essential usage rules. Every sentence serves a clear purpose without 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?

Given no output schema and minimal parameter documentation, the description lacks completeness: it does not explain return values, detailed behavior of 'complete,' or the structure of signedChunkDetails. While usage guidelines are thorough, the tool's functional contract is insufficiently defined.

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 coverage is 0% with no parameter descriptions, and the description adds no meaning for the four required parameters (folderId, communityId, signedUrlId, signedChunkDetails). The description fails to compensate, leaving the agent to infer parameter purposes from the tool name alone.

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 'Complete a multipart folder item upload,' specifying the verb and resource. It distinguishes the tool from siblings like create_folder_item, which initiates uploads. However, it could elaborate on what 'complete' entails in terms of finalizing the upload process.

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 explicit when-to-use guidance: check business permissions, call check_business_tool_access before collecting inputs, handle grace-period warnings, and never proceed when access is blocked. It also states that FREE businesses cannot use this tool, clearly defining exclusion criteria.

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