memtrace-public
Structural memory for AI coding agents. Bi-temporal graph, MCP-native, zero LLM calls. Cursor · Claude Code · Codex · Hermes · VS Code · Windsurf.
That is super cool. Checkout this repo which might give you super power to code quality and cut down 80% of token cost while keeping fable running longer jobs. https://github.com/syncable-dev/memtrace-public?tab=readme-o...

claude-context-local
Code search MCP for Claude Code. Make entire codebase the context for any coding agent. Embeddings are created and stored locally. No API cost.

snippets
Automatically extracts, processes, and indexes code snippets from GitHub repositories into a searchable vector database. (by cheolwanpark)

Project mention: Discovering Cryptographic Weaknesses with Claude | news.ycombinator.com | 2026-07-28
The only repos I find skills particularly useful for are in small languages with useful new tools. For elixir I have some tools pointing to cicada[1] for code search because it's better than grep and meaningfully reduces churn.

coco-search
Local-first hybrid semantic code search tool. Indexes codebases into PostgreSQL with pgvector embeddings via Ollama, combines vector similarity + keyword search with RRF fusion. Supports 30+ languages. Features CLI, MCP server, WEB dashboard and interactive REPL.

Project mention: Show HN: Semble – Code search for agents that uses 98% fewer tokens than grep | news.ycombinator.com | 2026-05-17
Would be nice to see the actual % token/time saving across end-to-end coding sessions over these time periods https://github.com/MinishLab/semble#savings
My observation is that greps and the processing of grep outputs account for only a small portion of overall consumption; I haven't measured this scientifically though.

droste-memory
Local MCP code-memory engine for AI agents: structural graph + semantic search, sharded storage, project isolation, and fractal code visualization.
GitHub: https://github.com/lorismascio17/droste-memory

codecontext
Reduce your LLM costs by 40-70% automatically. Routes prompts locally, compacts context, tracks real savings. (by batish52)
Project mention: I Tracked Every LLM API Call For a Week — 65% Were Unnecessary | dev.to | 2026-04-20So I built promptrouter — a gateway that sits between your code and the LLM API. For every prompt, it decides:
-
fidx
Local AI search engine for your files and agents — hybrid BM25 + vector semantic search (RAG) in one SQLite file. Millisecond queries, CPU-only, offline, no LLM in the query path.
Project mention: Fidx – local semantic search in one SQLite file, no LLM at query | news.ycombinator.com | 2026-07-04 -
trelix
🌲 Fast, reliable code intelligence — Tree-sitter AST parsing, contextual hybrid search, adaptive query planning, call-graph expansion & LLM synthesis. 20+ languages. Zero infra.
Project mention: I Built trelix Because I Was Tired of Grepping My Way Through Codebases | dev.to | 2026-07-05Everything is MIT licensed, on PyPI, and at github.com/sairam0424/trelix. The full documentation is in the repo README including the beast-mode activation block if you want all seven retrieval legs at once.
