What it does
Reading Invoice is an agent skill from kazukinagata/shinkoku. 請求書の画像を読み取り構造化データを返す。 他のスキルから呼び出されるほか、直接ユーザーが呼び出すことも可能。
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Documents & Office, covering Forms and invoices. 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
- Tasks that involve Forms and invoices
Example prompts
- “/reading-invoice”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- shinkoku pdf extract-text --file-path を実行する
- 抽出テキストに必要な情報（金額・日付・請求元等）が含まれていれば、テキストから構造化データを生成する
- テキストが不十分（スキャン PDF 等）の場合は shinkoku pdf to-image --file-path --output-dir で PNG に変換し、以下の画像読み取りフローに進む
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
Reading Invoice loads about 525 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 112 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.

請求書 画像読み取り
請求書の画像を読み取り、構造化データとして返すスキル。
PDF ファイルの場合
ファイルが PDF（.pdf）の場合、画像 OCR の前にテキスト抽出を試みる。
shinkoku pdf extract-text --file-path <path>を実行する- 抽出テキストに必要な情報（金額・日付・請求元等）が含まれていれば、テキストから構造化データを生成する
- テキストが不十分（スキャン PDF 等）の場合は
shinkoku pdf to-image --file-path <path> --output-dir <dir>で PNG に変換し、以下の画像読み取りフローに進む
画像読み取り方法
推奨: デュアル検証（並列2コンテキスト）
精度を高めるため、同じ画像を2つの独立したコンテキストで並列に読み取り、結果を照合する。
2つの独立した読み取りを実行する: サブエージェントが使える環境では、2つのサブエージェントを並列で起動し、それぞれ独立に画像を読み取る。 各サブエージェントには以下の「基本ルール」と「出力フォーマット」をプロンプトとして渡し、画像ファイルパスを指定する。
結果照合: 両方の読み取り結果から主要フィールド（金額等）を比較する。
一致の場合: そのまま採用。「2つの独立した読み取りで結果が一致しました」と報告する。
不一致の場合: ユーザーに元画像パスと両方の結果を提示し、正しい方を選択してもらう:
- 差異のあるフィールドを明示する
- A を採用 / B を採用 / 手動入力 の3択を提示する
フォールバック（サブエージェント非対応の場合）
サブエージェントが利用できない環境では、以下の手順で読み取る:
- 画像ファイルを直接 Read ツールで読み取る
- 以下の「基本ルール」と「出力フォーマット」に従ってデータを抽出する
- 抽出結果をユーザーに提示し、必ず目視確認を依頼する
⚠ デュアル検証が利用できないため、必ずユーザーに目視確認を依頼してください。
基本ルール
- 画像ファイルは Read ツールで読み取る（Claude Vision が自動的に画像を認識する）
- 金額は必ず int（円単位の整数）で返す。カンマや「円」は除去する
- 日付は YYYY-MM-DD 形式で返す
- 和暦は西暦に変換する（令和7年 → 2025、令和6年 → 2024、平成31年 → 2019）
- 読み取れないフィールドは UNKNOWN（文字列）または 0（金額）とする
- 複数ファイルを渡された場合は全て順に処理してまとめて返す
出力フォーマット
画像を読み取り、以下の形式で返す:
---INVOICE_DATA---
vendor: 請求元名
invoice_number: 請求書番号
invoice_registration_number: 適格請求書発行事業者番号（T+13桁）
date: YYYY-MM-DD
total_amount: 請求金額合計（int）
tax_amount: 消費税額（int）
items:
- description: 品目・サービス名
amount: 金額（int）
quantity: 数量（int）
tax_rate: 税率（10 or 8）
---END---抽出のポイント
- 請求金額の合計（税込）を最優先で抽出する
- 消費税額を確認する（10% と 8% 軽減税率の区分があれば区別する）
- インボイス番号（T+13桁の適格請求書発行事業者登録番号）の有無を確認する
- 請求書番号がある場合は抽出する
- 請求元（vendor）の名称を抽出する
- 日付は請求日を使用する（発行日と請求日が異なる場合は請求日を優先）
- 明細行は読み取れる範囲で抽出する（不明な場合は items を空にする）
複数ファイルの処理
複数のファイルパスが指示された場合:
- Glob ツールでファイル一覧を取得する（パターンが指示された場合）
- 各ファイルを Read ツールで順に読み取る
- 全ファイルの結果をまとめて返す（各結果の前にファイル名を記載する）
