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

Annotations already declare destructive=true, idempotent=true, and openWorld=true. The description adds two useful non-annotation facts: the operation is app-only authenticated and bytes are excluded from model context/results. However, it says nothing about the begin/chunk/status/complete/cancel action lifecycle, which is the core behavioral model of this tool.

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?

Two short sentences are front-loaded, but for a 6-parameter, multi-action import tool this is under-specification rather than effective conciseness. The brevity leaves core semantics unexplained.

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 complex destructive, idempotent, multi-action tool with no output schema and 0% schema coverage, this description is grossly incomplete. An agent cannot determine the correct action sequence, required parameters per action, or expected behavior from either the description or the schema.

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% across 6 parameters with nested objects and a 7-value action enum. The description mentions none of them, so the agent gets no help understanding the action lifecycle, source kinds (upload/url), replace semantics, or size bounds beyond what the raw schema shows.

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?

"App-only authenticated bounded import transfer" largely restates the tool name (transfer_document_import_from_app) without clarifying what the operation actually accomplishes. It never says this is a multi-step document import flow, nor distinguishes it from siblings like begin_document_import or complete_document_import.

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 invoke this tool versus the many import-related siblings (begin_document_import, complete_document_import, get_document_import_status, cancel_document_import). The reader cannot tell whether this is the entire flow, one step, or an alternative path.

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