Plannotator is a local workspace designed for developers to take control of AI coding agents by reviewing plans, inspecting code diffs, and annotating feedback before execution. It solves the chaos of managing agent interactions across tools by keeping your review data private and securely routed back to the agent. Ideal for engineers and teams leveraging AI assistants who want seamless integration without sacrificing control or privacy.
Agents is a multi-harness plugin marketplace for AI coding tools like Claude Code, Cursor, and GitHub Copilot. It solves the problem of fragmented, tool-specific agent ecosystems by providing a central hub for discovering and using skills across different platforms. This project is for developers and teams who use multiple AI coding assistants and want a consistent, extensible set of capabilities available everywhere they work.
cmux is a free, open-source terminal for macOS built on Ghostty's rendering engine. It solves the problem of terminal clutter and context switching by providing vertical tabs with git status, notification rings for AI agents, and an in-app browser. It's designed for developers and engineers who multitask with coding agents, need to manage multiple sessions, and want a programmable, native terminal experience.
pstack-claude provides rigorous, multi-agent workflow implementations of Poteto's pstack methodology, translated for Claude, Codex, Pi, and other major AI coding assistants. It solves the problem of vendor lock-in and inconsistent agent behavior by offering standardized, high-quality workflows across different AI harnesses. This repository is for developers and teams who want reliable, reproducible AI-assisted coding patterns that work seamlessly whether they're using Claude, Gemini, GitHub Copilot, or other AI coding tools.
codebase-memory-mcp is an MCP server that indexes repositories into a persistent knowledge graph of functions, classes, and dependencies. It solves the problem of AI agents inefficiently reading files one-by-one, enabling structural queries with ~120x fewer tokens. It's for developers and teams using AI coding assistants like Claude Code who need fast, local, and deep codebase understanding.
Context window optimization for AI coding agents. Sandboxes tool output (98% reduction), persists session memory, and enforces routing across 17 platforms via MCP + hooks.
Atlas is a native macOS editor built to manage the work around coding—research, planning, and knowledge—alongside the AI agent threads that turn them into commits. It solves the problem of fragmented workflows by providing a unified planning surface where teams of humans and multiple AI agents can collaborate efficiently. It's for developers and engineering teams who use AI coding assistants like Claude, Codex, and Gemini and want to coordinate their work in a single, local-first application.
Archify is an agent skill that transforms plain English descriptions of systems into beautiful, interactive HTML diagrams. It solves the problem of creating and maintaining accurate, up-to-date architecture, workflow, and sequence diagrams by generating them directly from conversation. It's for developers, architects, and teams who need to quickly visualize, share, and verify system designs with motion, exploration, and crisp export built-in.
Obsidian Skills is a set of tools that enables AI agents to read from and write to Obsidian vaults using its command-line interface and open formats like Markdown and JSON Canvas. It solves the problem of AI assistants being unable to directly access or manipulate personal knowledge bases, bridging the gap between conversational AI and structured note-taking. It's designed for developers, researchers, and power users who want their AI agents to seamlessly integrate with and act upon their Obsidian-based knowledge systems.
Orca is an Agent Development Environment (ADE) that lets you run and manage multiple AI coding agents like Claude Code, Codex, and OpenCode in parallel, within isolated worktrees. It solves the problem of coordinating and reviewing output from a fleet of agents by providing integrated terminals, a file editor, and git tracking to keep all branches moving. It's designed for developers and teams who want to automate and scale their coding workflows using multiple AI assistants simultaneously.
