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

Adds real context beyond the annotations: the login prerequisite, the per-call token cost ('호출마다 토큰 1소진'), and how the server treats repeated calls without a key. However, 'Initialize ... declaration' plus 'recover that request after a lost response' implies server-side state creation, which sits uneasily with readOnlyHint=true, and the description never clarifies what state (if any) is persisted.

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 auth precondition is correctly front-loaded and most sentences carry information, but 'use a new key for a new execution' and 'Without it, calling again remains a new request' restate the same point. The trailing Korean token-cost note is a dangling fragment rather than integrated content.

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, the description should say what an init call returns or what workflow step follows (e.g. save/submit), which it does not. Auth, idempotency and cost are covered, but an agent cannot tell from this text what it receives or how to continue the declaration.

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%, but the schema's request_idempotency_key description explicitly defers to the tool description, so this text is doing necessary work: defining the key's lifecycle and warning that a provider-specific idempotency_key is a different field. account_link_id semantics (same as login) are only lightly touched.

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 a concrete verb and resource: 'Initialize qualification acquisition declaration,' which distinguishes it from the sibling qualification change/loss/dependent init tools. It does not explicitly contrast itself with those siblings by name, so it stops short of a 5.

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 precondition ('REQUIRES prior nhis_edi__session__login call with same account_link_id') and detailed when-to guidance for the idempotency key: reuse only to recover a lost response, new key for a new execution. It never says when to choose this acquisition init over change/loss/dependent init, so there is no exclusion guidance.

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