## 30-Second Quickstart

**1. Get a free API key** → **<https://dashboard.nutrient.io/sign_up/?product=processor>**

**2. Install & configure:**

```bash
# Install the skill (works with 40+ agents)
npx skills add PSPDFKit-labs/nutrient-agent-skill

# Set your API key
export NUTRIENT_API_KEY="pdf_live_..."
```

**3. Ask your agent:**

> *"Extract the text from invoice.pdf"*

That's it. Your agent now has full document processing capabilities.

---

## Requirements

- Python 3.10+
- `uv` installed: <https://docs.astral.sh/uv/>
- Nutrient API key

---

## Supported Agents

Works out of the box with **40+ AI coding agents**:

Any agent that supports the [Agent Skills](https://agentskills.io) standard works automatically.

## Real-World Workflows

### 🔍 Workflow 1: OCR a scanned document and extract text

You have a scanned PDF — no selectable text. Ask your agent:

> *"OCR scanned-contract.pdf in English and extract the text to a file"*

**What happens:**
```
scanned-contract.pdf (image-only)
  → OCR (English) → searchable-contract.pdf (selectable text)
  → Extract text → contract-text.txt
```

### 📋 Workflow 2: Fill a PDF form and sign it

You have an onboarding form to complete. Ask your agent:

> *"Fill employee-onboarding.pdf with name 'Jane Smith', start date '2026-03-01', and department 'Engineering', then digitally sign it"*

**What happens:**
```
employee-onboarding.pdf (blank form)
  → Fill fields (name, date, department)
  → Digital signature (CMS)
  → employee-onboarding-signed.pdf ✅
```

### 🔒 Workflow 3: Redact PII before sharing

You need to share a document but it contains sensitive data. Ask your agent:

> *"Redact all social security numbers, email addresses, and credit card numbers from patient-records.pdf"*

**What happens:**
```
patient-records.pdf (contains PII)
  → Detect SSNs, emails, credit cards
  → Apply black redaction boxes (irreversible)
  → patient-records-redacted.pdf 🔒
```

> **Tip:** For smarter redaction, try: *"Use AI redaction to find and remove all personally identifiable information from contract.pdf"* — this uses contextual AI analysis instead of pattern matching.

## Installation

### Using `npx skills` (Recommended)

```bash
# Install to all detected agents
npx skills add PSPDFKit-labs/nutrient-agent-skill

| **Claude Code** | `.claude/skills/` | `~/.claude/skills/` |
| **Codex CLI** | `.codex/skills/` | `~/.codex/skills/` |
| **Gemini CLI** | `.gemini/skills/` | `~/.gemini/skills/` |
| **Cursor** | `.cursor/skills/` | `~/.cursor/skills/` |
| **GitHub Copilot** | `.github/skills/` | `~/.copilot/skills/` |
| **OpenCode** | `.opencode/skills/` | `~/.config/opencode/skills/` |
| **Windsurf** | `.windsurf/skills/` | `~/.codeium/windsurf/skills/` |
| **Amp** | `.agents/skills/` | `~/.config/agents/skills/` |
| **OpenClaw** | `skills/` | `~/.moltbot/skills/` |
| **Roo Code** | `.roo/skills/` | `~/.roo/skills/` |

Example for Claude Code:

### Script Model

- `scripts/*.py` are single-operation scripts only.
- Multi-step workflows are generated at runtime in a temporary script from `assets/templates/custom-workflow-template.py`.
- Do not commit runtime pipeline scripts.
- Use `references/` for HTML/URL generation, compliance outputs, and other workflows that are easier to express as direct API payloads or temporary pipelines.
