RisingWave's agent-skills package injects streaming SQL expertise into 18 AI coding assistants (Claude Code, GitHub Copilot, Cursor, Windsurf, and more) via the agentskills.io open spec. It ships two skill modules: core RisingWave connectivity and 14 best-practice rules covering CDC ingestion, materialized view patterns, time-windowed aggregations, and common pitfalls. Install via npm CLI which auto-detects which agents you have installed. Apache 2.0 licensed.

Tabstack is a web data and browser automation API built by ex-Mozilla engineers that abstracts away the entire scraper infrastructure problem. You pass it a URL and a JSON schema describing the shape of data you want — Tabstack handles navigation, extraction, and normalization, returning clean structured output every time. No Playwright setup, no proxy rotation, no broken selectors. Beyond structured extraction, Tabstack supports agentic browser automation: multi-step flows where you describe what to accomplish rather than scripting each click. The platform bakes intelligence into every API call, adapting when page structures change so your pipelines don't break when a site updates its layout. Launched from the Mozilla incubator, it inherits a browser-first engineering culture with deep knowledge of web standards and bot-resilient navigation. Tabstack targets the large cohort of developers who've abandoned web scraping because maintenance cost outweighs the value — and the even larger group of AI engineers who need live web data in their pipelines without building custom connectors for every source. The schema-first API makes it a natural fit for LLM pipelines that need structured grounding on web content.
Reviewer scorecard
“AI coding assistants hallucinate streaming SQL constantly — CDC ingestion patterns, windowed aggregations, and materialized view semantics are all places where generic training data fails hard. An installable skill package that auto-detects your agents and patches in correct context is exactly the right fix. Worth adding if you're building on RisingWave.”
“Schema-first data extraction is exactly what AI pipelines need — define the shape of your data once and stop prompt-engineering JSON out of an LLM on every request. The Mozilla pedigree means they actually understand how browsers work under the hood.”
“This only matters if you're already using RisingWave, which is a niche streaming SQL database with a much smaller user base than Postgres or Kafka. Four stars on GitHub suggests the audience is narrow. The agentskills.io spec is interesting as a standard but it's vapor if no one else adopts it.”
“The 'it always matches' promise falls apart on JavaScript-heavy SPAs and sites with aggressive bot detection. Until there's a public benchmark on real-world success rates across varied sites, I'm keeping Firecrawl for production pipelines.”
“Every database, framework, and specialized API is going to need its own skill package for AI coding agents. RisingWave is just the first mover on an inevitable pattern. The open spec is the actually important thing here — it could become how the entire ecosystem teaches agents about domain-specific tools.”
“Tabstack's schema-driven API is a foundational building block for the agentic web — a world where AI agents can universally read any web source as structured data without custom integrations for every domain.”
“Not really in my wheelhouse — streaming SQL and data pipelines are developer infrastructure. But the 'teach your AI assistant the local dialect' concept is one I'd love to see applied to design systems, component libraries, and brand guidelines. Someone should build this for Figma.”
“Being able to pull structured competitor pricing or product data for research without filing a dev ticket is a genuine workflow unlock. Tabstack makes web data accessible to people who aren't engineers.”
