Project mention: 3..2..1 Launch!: My journey from zero to Django Contributions | dev.to | 2026-05-15
PR: Link This is very interesting bug. You can perform coalesce to receive not-null first value from given columns fetching. However, column's type are vary. Let imagine you coalesce Column A (string), Column B (JSON).

Project mention: Why everyone is talking about loop-engineering and how is it changing agentic ai workflows? Claude Code and Web Scraping examples | dev.to | 2026-06-10
Think about what a mature scraping project already contains. There is a schema that every item must validate against. There are field coverage thresholds, because a run where only 60% of products have prices is a failed run no matter what the exit code says. There are expected item counts, error rate ceilings, and finish reason checks. In the Scrapy world we even have a dedicated framework for all of this, and I wrote about it earlier this year in my post on giving spidey-senses to your spiders with Spidermon. Here is the reframe that I cannot stop thinking about: a Spidermon monitor suite is a rubric. Our community spent a decade encoding "what good data looks like" into machine-checkable criteria, because silent failure is scraping's oldest enemy, the spider that runs green for three weeks while quietly shipping garbage. We built the evaluator long before we had a generator capable of acting on its feedback. Every other field adopting loop engineering has to invent its definition of done from scratch. We just have to plug ours in. The missing piece was never detection. It was what happens after detection, which until now was a human reading an alert, opening the site, sighing at the redesign, and rewriting selectors. Models like Fable 5, which Anthropic says can work autonomously far longer than any previous Claude model, are finally good enough to sit inside that gap. John Rooney saw early versions of this pattern when he built scraping agents for 30 days, and the lesson that stuck with me from his series is that agents fail not from lack of capability but from lack of structure around them. Loops are that structure.

LLM / agentic frameworks: LangChain, LlamaIndex, LangGraph, AutoGen, MCP, RAG. (Fiddler and Razorpay both list these. "Hands-on counts, not just awareness," as Razorpay puts it.)

Glasswing is cool. Open-source frameworks like CAI are making progress — but mostly on the offensive side, using LLMs for penetration testing and vulnerability research. On the defensive side, the tooling barely exists. There's no open-source equivalent for the kind of adaptive monitoring and response I'm describing here.
