Domscribe is an open-source bundler plugin that solves a concrete, frustrating gap in AI-assisted frontend development: agents like Claude and Cursor are great at editing source files, but they have no way to trace which file owns a given rendered element. Domscribe assigns stable IDs to every DOM element at build time and generates a manifest mapping each element to its exact source file, component tree, props, and state. AI coding agents connect via MCP to query any live node in the browser — or click elements in a visual overlay to pass targeted UI context directly into the agent's tool call. The implementation is clean. All debug metadata is stripped at production build time, so there's zero runtime overhead. The manifest only ships in development, keeping bundle sizes clean. It supports React, Vue, Next.js, Nuxt, and all major bundlers: Vite, Webpack, and Turbopack. The MCP server can be pointed at any agent — Claude Code, Cursor, Windsurf, or raw Claude API via any compatible client. This is a genuinely practical tool for teams doing agentic UI work. The bidirectional bridge — source-to-DOM *and* DOM-to-source — means agents no longer need to guess which component renders what. It's MIT licensed, fully local, and has no cloud dependency. A small but meaningful infrastructure piece for the emerging agentic frontend workflow.

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
“This fills a real gap I've been hitting weekly. When I tell Claude to 'fix the button in the header,' it has no idea which file that button lives in. Domscribe gives agents ground truth about the rendered DOM — it's the missing link for serious agentic frontend work.”
“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.”
“Right now this is very early — 0 production deployments documented, minimal community adoption. The MCP spec is also still evolving fast, which means integrations could break. Worth watching but I'd wait for a v1 with more real-world usage before betting a production workflow on it.”
“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?”
“Source maps were table stakes for debugging JavaScript. DOM-to-source maps will become table stakes for agentic UI development. Domscribe is early infrastructure for a world where agents refactor entire UIs from a single natural language instruction. The teams building this kind of tooling now will define the standard.”
“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.”
“Designers working with component libraries have always hated the 'where does this button live' problem. Domscribe with the visual overlay mode means I can click any element in a running app and immediately send its exact component context to an agent. That's a qualitatively better workflow for design system work.”
“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.”
