소득공제·세액공제 항목을 최적 조합으로 극대화하는 공제 최적화 엔진. An agent skill from revfactory/harness-100.

  • SKILL.md covers 소득공제 항목 체계 (근로소득 기준), 세액공제 항목 체계, 공제 최적화 알고리즘 and 세율 구간별 공제 효과, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Deduction Optimizer Engine is an agent skill from revfactory/harness-100. 소득공제·세액공제 항목을 최적 조합으로 극대화하는 공제 최적화 엔진. 'deduction-optimizer' 에이전트가 공제 항목을 분석하고 최적 조합을 도출할 때 이 스킬의 공제 한도표, 우선순위 알고리즘, 시뮬레이션 방법을 반드시 활용해야 한다. '공제 최적화', '세액공제 극대화', '연말정산 시뮬레이션' 등에 사용한다. 단, 소득 분류나 세액 계산은 이 스킬의 범위가 아니다.

Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is Apache-2.0.

Example prompts

  • “deduction-optimizer”
  • “/deduction-optimizer-engine”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Deduction Optimizer Engine loads about 711 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 270 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~711

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
소득공제·세액공제 항목을 최적 조합으로 극대화하는 공제 최적화 엔진. 'deduction-optimizer' 에이전트가 공제 항목을 분석하고 최적 조합을 도출할 때 이 스킬의 공제 한도표, 우선순위 알고리즘, 시뮬레이션 방법을 반드시 활용해야 한다. '공제 최적화', '세액공제 극대화', '연말정산 시뮬레이션' 등에 사용한다. 단, 소득 분류나 세액 계산은 이 스킬의 범위가 아니다.

Deduction Optimizer Engine — 공제 최적화 엔진

소득공제·세액공제 항목의 한도, 요건, 최적 조합 전략을 제공한다.

세액공제율 구분 (총급여 기준)
연금저축·IRP 세액공제율:
  총급여 5,500만원 이하: 15%
  총급여 5,500만원 초과: 12%

최대 세액공제액:
  연금저축 600만원 × 15% = 90만원
  IRP 포함 900만원 × 15% = 135만원

공제 최적화 알고리즘

우선순위 결정 공식
공제 효율성 = 실질 세금 감소액 / 필요 지출액

소득공제 실질 감소: 공제액 × 한계세율
세액공제 실질 감소: 공제액 × 공제율 (직접 차감)

우선순위:
1. 세액공제 (직접 세금 감소) > 소득공제 (간접 감소)
2. 높은 공제율 항목 > 낮은 공제율 항목
3. 한도 미달 항목 > 한도 도달 항목
4. 필수 지출 동반 항목 > 추가 지출 필요 항목
최적화 시뮬레이션 순서
Step 1: 무조건 공제 적용 (인적공제, 4대보험)
Step 2: 연금저축/IRP 세액공제 극대화 (가장 높은 ROI)
Step 3: 신용카드 등 사용금액 공제 최적 배분
Step 4: 의료비·교육비 세액공제 확인
Step 5: 월세·주택자금 공제 확인
Step 6: 기부금 공제 확인
Step 7: 한도 초과/미달 항목 재조정
신용카드 공제 최적화
공제율 차이:
  신용카드: 15%
  체크카드/현금영수증: 30%
  전통시장: 40%
  대중교통: 40%
  도서·공연: 30%

최적 전략:
  1. 총급여 25%까지 → 신용카드 (혜택 극대화)
  2. 25% 초과분 → 체크카드/현금영수증 (공제율 2배)
  3. 전통시장·대중교통 → 추가 한도 활용
