AOCI Code Index
A local-first MCP server and CLI in Go that creates a Git-versioned map of your codebase and database schema for coding agents. It gives Claude Code, Codex, Cursor, and opencode persistent system context so they stop re-reading the repo on every task.
Multi Model Menu
Magpie is a menu bar application for switching the underlying model of various AI coding agents from a single interface. It solves the practical pain point of managing model assignments across different agent tools.
AI Agent Console
Agent Console is local-first observability software for AI coding agents like Claude Code and Codex, tracking tokens, cache, models, and cost. It is notable for its self-hosted team hub and policy hooks for managing agent usage.
LLM Decision Model
AnyJev converts any LLM into a Jev-style decision model with typed decisions and real probabilities, requiring no training. It is backed by Nokia and offers a novel approach to creating calibrated decision models.
Plain Language Skills
Open Steps provides plain-language agent skills for Claude Code, Codex, Cursor, and Gemini CLI to create honest session reports and clear next steps. It is aimed at non-engineers who want better visibility into the development process.
DeepSeek Agent Harness
Dscode is a terminal coding agent for macOS built on the DeepSeek harness, featuring a persistent shell, subagents, and Chrome MCP integration. It is notable for enabling multiple interfaces to share one live session runtime.
AI Browser Agent
Dots is an open-source web AI agent with its own browser designed to avoid bot blocking. It is notable for its rapid early growth and focus on a common failure point for web agents.
Japanese Text Refiner
Yomiyasu is an agent skill for refining AI-generated Japanese into more natural, readable text, targeted at technical documents. It is a focused, well-executed tool for Japanese users of AI coding environments.
Halo Training Framework
Open-source framework from White Circle for training large language and multimodal models, supporting pre-training, SFT, preference optimization, and asynchronous RL. Runs on one GPU or multiple nodes with distributed training features.
