PruvaGraph

What it does

PruvaGraph is a 28-layer local knowledge graph engine that makes AI coding assistants (Claude/Cursor) affordable. Most tools scan your entire repo into the LLM on every run—costing hundreds/month. PruvaGraph bypasses the LLM for 99% of queries using local AST parsing, MinHash deduplication, and a Privacy Shield for automatic secret redaction. We reduced our own extraction costs from $313/mo to ~$0.001/mo. PruvaGraph acts as an MCP server and includes a native VS Code extension.

  Smart model routing directly in Claude, Codex and CursorJun 2026 · github.com · ▲216

  We built a model router that plugs into coding agents (e.g. Claude Code, Codex, Cursor, etc.) and intelligently sends requests to the best model to serve them. Here's a quick demo of running it locally: https://www.youtube.com/watch?v=isKhAyivtfM. At Weave, we write most of our code with AI, and it's been getting more expensive. This came to a head when Opus 4.7 was released and, thanks to its tokenizer changes, our costs shot up. We knew we didn't need Opus for everything but we didn't want to lose out on the intelligence for the cases where you really need it. So we decided…

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
