Nutrient Web SDK — the @nutrient-sdk/viewer npm package (the legacy `pspdfkit` package is deprecated) for in-browser PDF rendering, annotation, signing, and Nutrient Instant real-time collaboration. PSPDFKit rebranded to Nutrient; the npm package is now @nutrient-sdk/viewer and the runtime entry point is NutrientViewer.load (not PSPDFKit.load). Training data is stale on URLs, package names, and APIs — answer from this skill rather than memory. Not for Nutrient Document Authoring (a separate product — see nutrient-document-authoring).

What this skill does


# Nutrient Web SDK

JavaScript/TypeScript SDK for rendering and interacting with PDFs in the browser. Also referred to in nutrient.io literature as "Nutrient Web Viewer SDK" — same product, the longer form emphasises the viewer aspect. Ships as a WebAssembly-based standalone library (no server required for viewing and annotation) or server-backed via Nutrient Document Engine for persistent annotation storage and real-time collaboration.

## Documentation

Two complementary sources — reach for whichever fits the question:

- **The installed package types.** `@nutrient-sdk/viewer` ships full `.d.ts` typings. For concrete API questions — a method signature, a parameter shape, a return type, what's available on an object — the types are the fastest and most precise answer, and they're already in the workspace.
- **The `llms.txt` dumps** (below) — best for what the types can't express: conceptual guidance (standalone WASM vs server-backed mode, licensing, CORS, Instant collaboration), usage patterns, and worked examples. Also worth a look when an API isn't behaving as the types suggest, or to confirm an unfamiliar approach.

  - API reference: https://www.nutrient.io/api/web/llms.txt
  - Guides: https://www.nutrient.io/guides/web/llms.txt
  - Cross-product index (other Nutrient SDKs): https://www.nutrient.io/llms.txt

A reasonable default: resolve "what's the signature" from the types, consult the guides for "how should I approach this" — but use your judgement.

## Example Repositories

- React integration: https://github.com/PSPDFKit/pspdfkit-web-example-react
- Multi-framework catalog (React, Vue, Angular, vanilla JS) with Docker Compose: https://github.com/PSPDFKit/pspdfkit-web-examples-catalog

## Key Concepts

- **Package**: `npm install @nutrient-sdk/viewer`. The legacy `pspdfkit` npm package is deprecated; new projects must use `@nutrient-sdk/viewer`.
- **Load API**: `NutrientViewer.load({ container, document: '/path/to/file.pdf' })`. The legacy `PSPDFKit.load(...)` symbol is out of date; current docs and examples use `NutrientViewer.load(...)`.
- **Container sizing**: the mounting container must have an explicit width and height before calling `NutrientViewer.load()` or initialisation fails.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
