Claw Code is a clean-room rewrite of Anthropic's Claude Code agent harness, born from a March 2026 incident where Claude Code's full TypeScript source was accidentally published to the npm registry inside a 59.8 MB JavaScript source map. Developer Sigrid Jin reverse-engineered the architecture and rebuilt it ground-up in Rust (72.9%) and Python (27.1%) under MIT license. The framework ships 19 permission-gated tools covering file operations, shell execution, Git commands, and web scraping — plus a multi-agent orchestration layer that can spawn parallel sub-agents, a query engine managing LLM streaming and caching, and full MCP support across six transport types. Session persistence with transcript compaction and 15 interactive slash commands round out a feature set that rivals the original. What makes Claw Code genuinely disruptive is provider freedom: where Claude Code locks you to Anthropic, Claw Code works with any LLM. It hit 72K GitHub stars on day one and crossed 100K by the end of the week — one of the fastest-growing repos in GitHub history. Whether Anthropic pursues legal action remains an open question, but the code is already forked thousands of times.

Mnemos
Local vector memory for Claude Desktop with 3D conversation visualization

Claude Desktop has no memory across sessions. You close the window and it forgets everything. Mnemos is an open-source MCP server that fixes this by watching your conversation files in real-time, indexing them with local ONNX embeddings (MiniLM-L6-v2), and enabling hybrid semantic + keyword search — all without a single byte leaving your machine. The v1.1 release adds a genuinely striking feature: a 3D semantic visualization that maps your conversations into a clustered constellation using UMAP dimensionality reduction and Three.js. You can scrub through a chronological timeline and watch the knowledge graph build in real time. It is, frankly, prettier than it needs to be. Built on .NET 9, SQLite FTS5, and React/Vite, Mnemos is one of the more technically ambitious "Claude memory" projects to appear on HN this week. The offline-first, MIT-licensed approach puts it in a different league from cloud-synced alternatives.
Reviewer scorecard
“Multi-provider support alone makes this worth exploring — no more being locked to Claude's API pricing. The Rust core means it's fast, and 19 permission-gated tools is a solid starting point for real agent workflows. I've already swapped it in for two internal projects.”
“This solves a real, painful problem with zero cloud dependency. The hybrid FTS5 + vector search is the right architecture — you get speed and semantic richness without compromising privacy. The .NET 9 stack is slightly niche but the setup looks smooth.”
“The whole project is legally precarious — even a 'clean-room rewrite' based on accidentally-published source code is a grey area that Anthropic's lawyers are surely eyeballing. Building production workflows on top of a repo that could get DMCA'd overnight is a real risk. Wait for the legal dust to settle.”
“It is a one-person Show HN project posted literally today with 2 GitHub stars. The 3D visualization is cool but has nothing to do with actually improving recall quality. Also: how often do you actually need to search old Claude conversations vs. just starting fresh?”
“This is what happens when proprietary agent architectures meet the open-source community — the architecture gets commoditized within weeks. We're entering a world where the LLM is the commodity and the agent harness is the moat, and Claw Code just made that moat public property.”
“Local-first AI memory is the correct long-term architecture. Every AI system we rely on should have this kind of persistent, private, searchable context layer. Mnemos is a prototype of what OS-level AI memory will eventually look like, and seeing it built today matters.”
“For creative workflows — rapid prototyping, generating design assets, iterating on copy — having an agent harness that isn't locked to one provider is genuinely freeing. The cost arbitrage between providers alone makes Claw Code worth setting up.”
“The 3D constellation visualization genuinely excites me — there is art in watching your conversation history render as a navigable space. For writers and researchers who use Claude heavily, the ability to rediscover old threads through semantic search could unlock something meaningful.”
