How to build a VS Code chat panel with server-sent event streaming, prioritized context-slot assembly, hybrid RAG retrieval, and a three-process webview architecture — no API keys, all open-source models.
How I added RAGAS-based faithfulness and context-utilization scoring to an open-source LLM governance engine — plus a post-response governance rule that catches hallucinations after the model has already started streaming.
How I built an open-source PII firewall and governance policy engine for LLMs in a weekend — blocks sensitive data before it reaches GPT-4o, with YAML rules, audit trail, and webhook alerts.
How to add full repository intelligence to an AI IDE: multi-language Tree-sitter chunking (Go, Rust, Java, JavaScript), BM25 hybrid search with RRF, .gitignore-aware file discovery, and new /index-dir and /search API endpoints.
Step-by-step: build a < 150ms fill-in-the-middle autocomplete engine using Tree-sitter chunking, nomic-embed-text, Chroma, and StarCoder2-3B. Part 1 of building Dhi — the open-source AI coding IDE.
A deep-dive into designing a full AI coding IDE using only open-source components — FIM autocomplete, chat-in-editor, multi-file agents, repo understanding, and sandboxed code execution.
