Show HN: AICF – a tiny "what changed" feed for AI/RAG (v0.1 minimal core) I’m proposing AICF (AI Changefeed) — a minimal, web-native way for sites to expose append-only change events. Instead of crawlers or RAG systems re-embedding everything, they can refresh only the sections that changed. Discovery: a /.well-known/ai-changefeed JSON points to a feed. Feed: an append-only NDJSON file with just 4 required fields (id, action, url, time) plus optional hints (anchor, checksum, note). Goal: cut wasted crawling/embedding while keeping docs/pricing/policy pages fresh for AI/agents. Spec & examples here: https://ift.tt/p7L3fxG Would love feedback: is the minimal core (anchors only, no chunks/vectors/push yet) the right starting point? Would you use this in your docs/RAG stack? https://ift.tt/p7L3fxG August 23, 2025 at 01:46AM
