Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kosis-statistics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

KOSIS Statistics

Use this skill when the user asks for Korean official statistics, KOSIS data, regional comparisons, statistical trends, chart generation, or statistics-based policy/business interpretation.

Tool Routing

  • Start with plan_query for chatbot-style natural-language statistics questions, then follow select_table_for_query, resolve_concepts, query_table, and compute_indicator when the plan asks for evidence collection.
  • Use answer_query only as a quick Tier A compatibility shortcut. Treat its deprecation_warning and 검증_주의 fields as load-bearing.
  • Use verify_stat_claims after answer_query when a numeric answer is used in a report, policy memo, or user-facing conclusion.
  • Use indicator_dependency_map before answering ratio/rate questions such as share, closure rate, startup rate, survival rate, or loan-to-sales burden.
  • Use stat_time_compare, analyze_trend, correlate_stats, forecast_stat, and detect_outliers for explicit analysis requests.
  • Use chart tools only when the user asks for a graph, chart, dashboard, map-like comparison, or visual summary.

Safety Rules

  • Do not invent a single value when answer_query returns NEEDS_TABLE_SELECTION.
  • Preserve the result's 기준시점, 단위, 통계표, 출처, and 검증_주의 in the final answer. Also surface used_period and period_age_years when present — they tell the user which timepoint was actually consumed and how stale it is.
  • Treat 검증_주의 entries as load-bearing, not decoration. Entries that begin with "요청 시작 시점 …", "사용 시점 … 경과", "의도 … 감지됐으나", or "비교 대상 …" mean the answer did not fully satisfy the question; reflect that uncertainty in the response instead of citing the number bare.
  • For correlation, regression, and policy-effect requests, state that correlation or before/after comparison does not prove causality.
  • For business counts, distinguish 기업 수, 사업체 수, and 자영업자 수.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
