What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

# Nutrient Document Processing

[Nutrient DWS Processor API](https://www.nutrient.io/api/) でドキュメントを処理します。フォーマット変換、テキストとテーブルの抽出、スキャンされたドキュメントの OCR、PII の編集、ウォーターマークの追加、デジタル署名、PDF フォームの入力が可能です。

## セットアップ

**[nutrient.io](https://dashboard.nutrient.io/sign_up/?product=processor)** で無料の API キーを取得してください

```bash
export NUTRIENT_API_KEY="pdf_live_..."
```

すべてのリクエストは `https://api.nutrient.io/build` に `instructions` JSON フィールドを含むマルチパート POST として送信されます。

## 操作

### ドキュメントの変換

```bash
# DOCX から PDF へ
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.docx"}]}' \
  -o output.pdf

# PDF から DOCX へ
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.pdf"}],"output":{"type":"docx"}}' \
  -o output.docx

# HTML から PDF へ
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"html":"index.html"}]}' \
  -o output.pdf
```

サポートされている入力形式: PDF、DOCX、XLSX、PPTX、DOC、XLS、PPT、PPS、PPSX、ODT、RTF、HTML、JPG、PNG、TIFF、HEIC、GIF、WebP、SVG、TGA、EPS。

### テキストとデータの抽出

```bash
# プレーンテキストの抽出
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.pdf"}],"output":{"type":"text"}}' \
  -o output.txt

# テーブルを Excel として抽出
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.pdf"}],"output":{"type":"xlsx"}}' \
  -o tables.xlsx
```

### スキャンされたドキュメントの OCR

```bash
# 検索可能な PDF への OCR(100以上の言語をサポート)
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"scanned.pdf"}],"actions":[{"type":"ocr","language":"english"}]}' \
  -o searchable.pdf
```

言語: ISO 639-2 コード(例: `eng`、`deu`、`fra`、`spa`、`jpn`、`kor`、`chi_sim`、`chi_tra`、`ara`、`hin`、`rus`)を介して100以上の言語をサポートしています。`english` や `german` などの完全な言語名も機能します。サポートされているすべてのコードについては、[完全な OCR 言語表](https://www.nutrient.io/guides/document-engine/ocr/language-support/)を参照してください。

### 機密情報の編集

```bash
# パターンベース(SSN、メール)
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.pdf"}],"actions":[{"type":"redaction","strategy":"preset","strategyOptions":{"preset":"social-security-number"}},{"type":"redaction","strategy":"preset","strategyOptions":{"preset":"email-address"}}]}' \
  -o redacted.pdf

# 正規表現ベース
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.pdf"}],"actions":[{"type":"redaction","strategy":"regex","strategyOptions":{"regex":"\\b[A-Z]{2}\\d{6}\\b"}}]}' \
  -o redacted.pdf
```

プリセット: `social-security-number`、`email-address`、`credit-card-number`、`international-phone-number`、`north-american-phone-number`、`date`、`time`、`url`、`ipv4`、`ipv6`、`mac-address`、`us-zip-code`、`vin`。

### ウォーターマークの追加

```bash
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.pdf"}],"actions":[{"type":"watermark","text":"CONFIDENTIAL","fontSize":72,"opacity":0.3,"rotation":-45}]}' \
  -o watermarked.pdf
```

### デジタル署名

```bash
# 自己署名 CMS 署名
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"document.pdf"}],"actions":[{"type":"sign","signatureType":"cms"}]}' \
  -o signed.pdf
```

### PDF フォームの入力

```bash
curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer $NUTRIENT_API_KEY" \
  -F "[email protected]" \
  -F 'instructions={"parts":[{"file":"form.pdf"}],"actions":[{"type":"fillForm","formFields":{"name":"Jane Smith","email":"[email protected]","date":"2026-02-06"}}]}' \
  -o filled.pdf
```

## MCP サーバー(代替)

ネイティブツール統合には、curl の代わりに MCP サーバーを使用します:

```json
{
  "mcpServers": {
    "nutrient-dws": {
      "command": "npx",
      "args": ["-y", "@nutrient-sdk/dws-mcp-server"],
      "env": {
        "NUTRIENT_DWS_API_KEY": "YOUR_API_KEY",
        "SANDBOX_PATH": "/path/to/working/directory"
      }
    }
  }
}
```

## 使用タイミング

- フォーマット間でのドキュメント変換(PDF、DOCX、XLSX、PPTX、HTML、画像)
- PDF からテキスト、テーブル、キー値ペアの抽出
- スキャンされたドキュメントまたは画像の OCR
- ドキュメントを共有する前の PII の編集
- ドラフトまたは機密文書へのウォーターマークの追加
- 契約または合意書へのデジタル署名
- プログラムによる PDF フォームの入力

Questions

What does the Nutrient Document Processing skill do?

The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.

Is Nutrient Document Processing safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can Nutrient Document Processing access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

How current is this page?

The grade is for one exact copy of the source (649b2d7452eb), read on 2026-09-21. The repository is watched, and a new audit runs when it changes — this is the first audit.
