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

Annotations only say readOnlyHint=false and destructiveHint=false; the description adds genuinely new behavioral facts — one token is consumed per call, an XBOSS task is created and its result stored, and the call is explicitly 'not purely read-only' even though nothing is submitted. The closing line about institution data changes following 'per-tool execution and existing confirmation procedures' is vague, but the core caveat is disclosed rather than left to annotations.

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?

It is front-loaded well (prerequisite first, then purpose, then idempotency rules), but the idempotency paragraph is dense and repetitive, the mixed English/Korean creates redundancy, and the final sentence about institution data changes is generic boilerplate that does not earn its place.

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 two-parameter, non-destructive validation tool with no output schema, the definition covers prerequisite auth, token cost, idempotency lifecycle, and the fact that nothing is persisted. The main omission is that it does not mention the dependency on the form opened by chg_init, which an agent would otherwise only learn from the input 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 coverage is 100%, but the schema entry for request_idempotency_key defers to the description, and the description supplies the real semantics: generate and save the key before the first request, reuse it only to recover a lost response, use a new key for a new execution, and treat provider-level idempotency_key as a distinct field. That is meaningful added meaning beyond the schema, though the 'anonymous taste calls' sentence is garbled and adds little.

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 opening sentence states a specific verb and resource: 'Validate employee qualification change draft without submission,' reinforced by the Korean title. It is clear what the tool does, though it does not textually distinguish itself from the sibling draft_validate tools (acqs/dependent/los) — the resource name in the tool ID does that work instead.

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 gives a concrete prerequisite: 'REQUIRES prior fourinsure__session__login call with same account_link_id,' plus detailed rules for when to reuse versus regenerate the idempotency key. However, it never states when to choose this over the other member_qualification draft_validate siblings, or that the draft relates to a form opened by chg_init — that linkage appears only in the schema description.

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