What it does
Tax Advisor is an agent skill from kazukinagata/shinkoku. This skill should be used when the user asks tax-related questions, wants advice on deductions or tax savings, or needs expert guidance equivalent to a tax accountant (税理士) or life planner. Trigger phrases include: "税金について教えて", "控除は使える？", "確定申告の相談", "節税", "ふるさと納税の上限", "iDeCoの効果", "住宅ローン控除", "青色申告のメリット", "消費税はかかる？", "扶養に入れる？", "配偶者控除", "医療費控除", "法人成り", "経費になる？", "税率を教えて", "所得税の計算", "住民税", "社会保険料", "103万の壁", "130万の壁", "インボイス", "簡易課税", "税制改正", "開業届", "副業バレ", "白色申告", "税務調査", "特定支出控除", "予定納税", "中間納付".
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 32 other files (for example `README.md`, `reference/blue-return.md` and `reference/business-expenses.md`).
It sits in Business, Finance & HR, covering Tax preparation and Accounting and bookkeeping. The repository describes itself as: 確定申告自動化 AI エージェントプラグイン — 帳簿管理から e-Tax 入力代行まで. The licence is MIT.
When your agent uses it
- Asks tax-related questions
- Wants advice on deductions
- Needs expert guidance equivalent to a tax accountant (税理士)
- Phrases include: 税金について教えて
Example prompts
- “税金について教えて”
- “控除は使える？”
- “確定申告の相談”
- “/tax-advisor”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 607574d. 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
Tax Advisor loads about 1.4k tokens when it runs. Until then it costs about 128 tokens; SKILL.md has 298 words of instructions outside code blocks.
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.

税務アドバイザー（Tax Advisor）
税理士・ライフプランナー相当の専門知識で、ユーザーの税務相談に回答するスキル。 令和7年分（2025年課税年度）の税制に基づく。
設定の読み込み（最初に実行）
shinkoku.config.yamlを Read ツールで読み込む- ファイルが存在しない場合は
/setupスキルの実行を案内して終了する - 設定値を把握し、相対パスは CWD を基準に絶対パスに変換する:
db_path: MCP ツールのdb_path引数に使用output_dir: 進捗ファイル等の出力先ベースディレクトリ- 各ディレクトリ: ファイル参照時に使用
回答の基本方針
1. 正確性の担保
- 回答は必ず reference/ ディレクトリ内のファイルを根拠とする
- 一般知識や推測で回答しない。根拠が見つからない場合はその旨を明示する
- 金額・税率・要件は reference ファイルの数値を引用する
- 条文・通達の参照を回答に含める（例: 所得税法第89条、所基通36-1）
2. 回答の構造
以下の構造で回答を組み立てる:
- 結論を先に: 質問に対する端的な回答
- 根拠の提示: 該当する条文・制度の説明
- 具体的な計算例: ユーザーの状況に合わせた試算（可能な場合）
- 注意点・落とし穴: reference/common-mistakes.md の関連項目
- 免責事項: 回答の末尾に必ず disclaimer を付記
3. 収入と所得の変換
ユーザーは「収入」で質問するが、税制上の判定は「所得」で行う。以下のルールを適用する:
- ユーザーが「年収」「収入」と言った場合 → 「所得」に変換して計算する
- 変換過程をユーザーに明示する（例: 「給与収入500万円 → 給与所得控除後の所得356万円」）
- 変換には reference/glossary.md の変換表を使用する
- 給与所得控除額は reference/income-tax.md の速算表を使用する
4. 令和7年分改正への対応
令和7年分（2025年）の税制改正を正確に反映する:
- reference/tax-reform/2025.md の改正内容を常に考慮する
- 前年以前の情報と混同しない（特に基礎控除額、給与所得控除額）
- 経過措置（reference/tax-reform/transition.md）の適用期限に注意する
- 翌年以降の予定改正（reference/tax-reform/upcoming.md）は参考情報として提示する
