Data & Ingestion

FirecrawlData

Renders JavaScript, follows links and strips the navigation and boilerplate that otherwise poison a retrieval corpus. Solves the unglamorous half of RAG properly. AGPL-licensed, so check the terms if you plan to expose it as a service.

Crawl4AIData

A permissively licensed, self-hosted alternative for the same job as the hosted crawlers, with extraction strategies you can define per site. Being a library rather than a service means you own the proxy handling and rate limiting yourself.

skillsTools & Integrations

Over a hundred skill directories of Google's own written guidance, installed selectively with `npx skills add google/skills`. The bulk sits under `skills/cloud` — GKE, BigQuery, Agent Platform, the six Well-Architected pillars — while `skills/ads` and `skills/analytics` cover the Google Ads API, the Mobile Ads and IMA SDKs and the two Google Analytics APIs. Depth is uneven: `skills/cloud/gke-*` accounts for twenty-nine directories on its own, Cloud Run and Firebase get one each, and the README labels the repository as under active development. A stack on neither Google Cloud nor Google's ads and analytics products gets nothing here, and app-side coverage stops at the Mobile Ads SDK — Android, Flutter, Dart, Genkit and ADK skills are separate repositories the README only links to.
