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

Annotations already declare destructive=true, readOnly=false, and idempotent=false. The description adds useful behavior beyond that: it freezes the current version, returns either completion or a pending_action_id, and requires the member's own approval. It still does not explain irreversibility or failure cases in detail.

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 English text is front-loaded and compact, with the effect, return shape, and approval requirement stated directly. The Chinese text duplicates the same content rather than adding new information, but overall the description is not bloated.

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 destructive mutation with no output schema and 0% schema description coverage, the description covers the core effect, return modes, and approval requirement. It still leaves gaps around how to handle the returned pending_action_id, permission requirements, stale-version behavior, and exact parameter semantics.

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 for all three parameters. It mentions order_pack_id, version, and request_id and clarifies that version should be the current version, but request_id's role is left vague and no parameter constraints or formats are explained.

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 and effect: marking a deposit paid and freezing the order pack at the current order_pack_id/version. It is more than a restatement of the name, but it does not explicitly distinguish itself from sibling approval-flow tools such as decide_pending_action.

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?

It provides implied usage conditions: after deposit payment and with the member's own approval. However, it does not say when to use this tool versus alternatives, nor does it name related siblings like decide_pending_action or list_pending_actions.

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