kb_biz_card__payments__page
Read-only

REQUIRES prior kb_biz_card__session__login call with same account_link_id. Fetch one KB Biz Card payments page from a prior search context. For an authenticated call, generate and save request_idempotency_key before the first request. Reuse it with the same arguments only to recover that request after a lost response; use a new key for a new execution. Without it, calling again remains a new request. This optional key is not available to anonymous taste calls. Keep any provider-specific idempotency_key unchanged; it is a different field. 호출마다 토큰 1소진

Input Schema

NameRequiredDescriptionDefault
pageYesPage number to fetch
search_contextYesSearch context returned by init/search
account_link_idNoAccount link ID (UUID v4). Optional — the server auto-resolves from your API key when omitted. Provide explicitly only when you have multiple certificates for the same provider. Each institution has a separate ID (Hometax != NHIS != NPS != FourInsure).
request_idempotency_keyNoOptional same-request recovery key for authenticated calls; see the tool description.

TDQS

A4.5/5.0
Behavior5/5

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

Beyond readOnlyHint/destructiveHint, it discloses authentication dependency, idempotency-key lifecycle, recovery behavior, per-call token consumption, and a caveat about anonymous test calls. That is substantial behavioral context for a read-only page-fetch operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

It front-loads the critical prerequisite and keeps the core purpose in one sentence. The idempotency paragraph is somewhat verbose and the 'anonymous taste calls' phrase is confusing, but most content earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

It covers prerequisites, context dependency, idempotency, and per-call cost, which is strong for a page tool without an output schema. It could mention pagination/response behavior or how to know when another page is needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds meaningful semantics for request_idempotency_key (when to generate, reuse, and not reuse it) and reinforces that account_link_id must match the login session. It does not add much for page or search_context beyond what the schema already says.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a concrete verb ('Fetch') and names the resource ('KB Biz Card payments page') plus the scope ('from a prior search context'), which distinguishes it from the search/init siblings that produce that context. An agent can identify the operation without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states a hard prerequisite (prior session login with the same account_link_id) and the correct context (prior search context), giving clear when-to-use conditions. It does not explicitly name sibling alternatives such as payments__search or payments__result, so it stops short of full routing guidance.

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