Nutrient Skills

AI agent skills for Nutrient APIs and SDKs. Works with Claude Code, Codex, Pi, Cursor, Gemini CLI, and other agents.

Why these skills

The document extraction skills aren't wrappers around a prompt. They run a real document engine locally, and the accuracy numbers come from a public benchmark, not a set we picked ourselves:

• Fast and free. pdf-to-markdown extracts digital-born PDFs at about 0.004 seconds per page — roughly 134× docling's throughput on the public 200-document opendataloader-bench corpus, at essentially the same overall accuracy (0.89 vs 0.89; docling edges it at the third decimal). (Throughput, not a like-for-like single-document race: Nutrient converts batch-parallel while docling runs sequentially — see the method.) Free up to 1,000 documents a month, no key and no signup.
• Tuned for how agents actually work. The skills tell the agent to parse once and search with a bounded grep, reaching for ranked retrieval only when a plain grep would flood context. In our own testing that noticeably cut the token cost of answering questions over a document, at the same accuracy — the win is the instructions, not just the tool.
• Accurate when the page is hard. The licensed --vision tier adds a local machine-vision pipeline for scanned, photographed, and handwritten documents. On the same corpus it tops every accuracy metric while still running faster than docling.
• Local by default. Binaries are signed and run on macOS (Apple Silicon), Linux, and Windows. The local CLI does not upload your source PDFs to Nutrient. (Two honest caveats: extracted text you then feed to your own LLM/agent goes to that model provider like any other prompt, and the CLI downloads its binary from Nutrient's CDN on first run.)

Available Skills

Plugin	Skill	Description
nutrient-dws	document-processor-api	Generate, convert, assemble, OCR, redact, sign, archive, and optimize documents via the Nutrient Document Web Services API
nutrient-dws	document-extraction-api	Parse documents into a structural model or Markdown via the Nutrient Data Extraction API
nutrient-dws	grounded-rag-ingestion	Chunk documents into provenance-carrying JSONL (element type, page, bbox, confidence, reading order) for grounded, auditable RAG pipelines
nutrient-dws	dws-viewer-api	Upload documents and mint viewer session JWTs for the Nutrient cloud Viewer API. Embeds interactive viewing, annotation, forms, and signing via cloud infrastructure — no viewing/storage servers to run (you still mint session tokens from your backend)
make-pdf	make-pdf	Generate PDFs from Markdown or HTML — single files or whole directories — with accessible PDF/UA, archival PDF/A, and watermark outputs, plus built-in conformance verification
remediate-pdf	remediate-pdf	Remediate existing PDFs: auto-tag with PDF/UA semantic structure (headings, lists, tables, reading order) via the Nutrient DWS Accessibility API (auto-tag only — verify output with the bundled verify-pdf.py)
pdf-to-markdown	pdf-to-markdown	Extract text from PDFs as structured, semantic Markdown
pdf-to-text	pdf-to-text	Extract layout-preserving plain text from PDFs
query	query	Find the most relevant passages in an extracted document with ranked (BM-25) search
nutrient-sdk-dev	13 SDK skills	Build with Nutrient SDKs — Web Viewer, Document Authoring, mobile (iOS/Android/React Native/Flutter/MAUI), server (Python/Java/Node.js/.NET), self-hosted Document Engine, and AI Assistant

Installation

npx skills (recommended)

Install using the Skills CLI:

npx skills add pspdfkit-labs/nutrient-skills --skill document-processor-api
npx skills add pspdfkit-labs/nutrient-skills --skill document-extraction-api
npx skills add pspdfkit-labs/nutrient-skills --skill grounded-rag-ingestion
npx skills add pspdfkit-labs/nutrient-skills --skill dws-viewer-api
npx skills add pspdfkit-labs/nutrient-skills --skill make-pdf
npx skills add pspdfkit-labs/nutrient-skills --skill remediate-pdf
npx skills add pspdfkit-labs/nutrient-skills --skill pdf-to-markdown
npx skills add pspdfkit-labs/nutrient-skills --skill pdf-to-text
npx skills add pspdfkit-labs/nutrient-skills --skill query

The nutrient-sdk-dev plugin's 13 per-SDK skills install the same way (e.g. --skill nutrient-web-sdk).

This works with Claude Code, Codex, Cursor, Gemini CLI, and many other agents.

To list all available skills in this repo:

npx skills add pspdfkit-labs/nutrient-skills --list

Claude Code / Codex plugin marketplace

Both Claude Code and Codex support the /plugin command:

/plugin marketplace add pspdfkit-labs/nutrient-skills
/plugin install nutrient-dws@nutrient-skills
/plugin install make-pdf@nutrient-skills
/plugin install remediate-pdf@nutrient-skills
/plugin install pdf-to-markdown@nutrient-skills
/plugin install pdf-to-text@nutrient-skills
/plugin install query@nutrient-skills
/plugin install nutrient-sdk-dev@nutrient-skills

After installation, the plugin's skills will automatically load in all future sessions.

Pi

You can install the Nutrient skills with:

pi install git:github.com/PSPDFKit-labs/nutrient-skills

Pi will load all skills from the packaged plugins/*/skills directories. If you only want to try the package without installing it, use:

pi -e git:github.com/PSPDFKit-labs/nutrient-skills

You can still point Pi at a specific plugin's skills/ directory or at the repo-wide plugins/ directory in ~/.pi/agent/settings.json or a project-local .pi/settings.json if you prefer manual control.

Manual / any agent

Clone the repository and point your agent at the skill directory:

git clone https://github.com/pspdfkit-labs/nutrient-skills.git
# Skills live under plugins/<plugin>/skills/<skill>/SKILL.md

Reference SKILL.md directly in your agent's context, or symlink the skill directory into wherever your agent resolves skills.
