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

Beyond the readOnlyHint/destructiveHint annotations, it discloses the auth prerequisite, the per-call token cost ("호출마다 토큰 1소진"), the replay semantics of the idempotency key, and that anonymous calls cannot supply it. What is missing is any statement of what the init produces or whether server-side draft state is created — notable tension with readOnlyHint=true for an "initialize" operation.

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 front-loaded in caps and each sentence carries a distinct rule. It is dense but not padded, with only minor drag from the awkwardly translated "anonymous taste calls" phrasing and the trailing Korean cost line.

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?

Auth, cost, and idempotency are covered, but for a multi-step init tool with no output schema the description never indicates what the call returns or which tool to invoke next (e.g., a save/submit sibling), leaving the flow incomplete for an agent.

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 both parameters are documented structurally; the description nonetheless adds real semantics for request_idempotency_key (generate before first request, reuse only to recover a lost response, new key for a new execution) and distinguishes it from a provider-specific idempotency_key field the agent must not overwrite.

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 names a specific verb and resource ("Initialize qualification change declaration"), which distinguishes it from the sibling acquisition/loss/dependent init tools without naming them. It is clear what the tool starts, though it never says what state or handle the caller receives back.

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 prerequisite is stated up front and unambiguously: a prior nhis_edi__session__login with the same account_link_id. It also spells out when to reuse the idempotency key versus mint a new one. It does not, however, tell the agent when to prefer this tool over the neighboring qualification__acquisition/loss/dependent init siblings.

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