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

Annotations already declare readOnlyHint=false and destructiveHint=false, and the description correctly reinforces this ('순수 읽기 전용이 아닙니다'). It adds genuinely useful behavior not in the annotations: every call consumes one token, an XBOSS task is created, the result is persisted, and provider-specific idempotency_key fields must not be altered. Missing is any statement of what the call returns or what confirmation steps precede the write.

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 prerequisite is correctly front-loaded, but the body is a long mixed English/Korean block that returns to the idempotency key three times and contains an unclear translated phrase ('anonymous taste calls'). Several sentences could be merged without losing information.

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?

With no output schema and no described return value, an agent cannot tell what 'initialize' hands back (draft identifier, form payload, task handle). Auth prerequisites and write semantics are covered well, but the response side is entirely absent for a mutating init call.

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 100%, so the baseline would be 3, but the description adds real semantics for request_idempotency_key: generate and persist it before the first request, reuse only for recovery, and it is unavailable to anonymous calls. It also ties account_link_id to the login session ('same account_link_id'), which the schema does not say.

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?

States the verb+resource ('Initialize workplace withdrawal declaration') and adds that the call creates an XBOSS task and stores the processing result, which goes beyond the title. The term 'initialize' still leaves unclear whether a draft, a form session, or a server-side job is created, so the exact artifact produced is ambiguous.

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?

Gives an explicit prerequisite ('REQUIRES prior fourinsure__session__login call with same account_link_id') and precise idempotency-key usage rules (new key for a new execution, reuse only to recover a lost response). It does not name any alternative tool or state when not to use this one, so sibling routing is left to inference.

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