ascii-chat: Video Chat in Your Terminal
ascii-chat turns webcam video into colored terminal art for live, multi-person calls over a client-server network. It also supports audio, encryption, and media from files or URLs, but setup involves a substantial native dependency stack.
feynman: Research Papers with an AI Agent
Feynman is a TypeScript CLI agent for investigating research topics, reviewing papers, and comparing sources. It suits researchers and developers who want structured, citation-aware literature work and can configure a model provider.
Lean: Build and Run Algorithmic Trading Strategies
QuantConnect Lean is an event-driven engine for developing, backtesting, and live trading algorithmic strategies across financial markets. It suits quantitative developers who want a modular C# engine with Python support and local or cloud-assisted workflows.
engram: Give AI Coding Agents Persistent Memory
Engram is a Go-based memory system that helps AI coding agents retain useful project knowledge between sessions. It stores memories locally in SQLite and makes them available through MCP, a CLI, an HTTP API, and a terminal UI.
GitNexus: Map Codebases for AI-Assisted Analysis
GitNexus indexes a codebase as a knowledge graph and exposes its relationships through CLI and MCP tools. It helps developers and AI coding agents trace dependencies, understand execution flows, and assess change impact.
clawflows: Manage Reusable OpenClaw Agent Workflows
ClawFlows installs and manages reusable workflows for OpenClaw agents, including scheduled routines and on-demand tasks. It suits OpenClaw users who want to extend agent behavior with editable workflows instead of maintaining scattered instructions.
codegraph: Give Coding Agents a Local Code Knowledge Graph
CodeGraph builds and maintains a local graph of code structure so AI coding agents can retrieve relevant source, call paths, and change impact without exploring files one by one. It connects to multiple agents through MCP and supports many languages.
opencode: Work with an Open Source AI Coding Agent
OpenCode is an open source AI coding agent for developers who want AI assistance in their coding workflow. It offers build and read-only plan agents, a terminal UI, and desktop apps in beta.
apm: Manage Dependencies for AI Agent Setups
APM manages AI-agent instructions, skills, prompts, plugins, and MCP servers through a project manifest and lockfile. It helps teams reproduce agent configurations across supported coding clients and apply installation security and policy controls.
flyai-skill: Search Travel and Booking Options with AI Agents
FlyAI connects Claude Code, OpenClaw, and compatible agents to Fliggy travel search through a command-line tool. Use it to find flights, hotels, trains, attractions, and other travel services and receive structured results with booking links.
graphify: Turn Codebases into Queryable Knowledge Graphs
Graphify builds a queryable knowledge graph from code, documentation, schemas, and other project files. It helps developers and AI coding assistants explore relationships, trace paths, and understand codebases without relying on a vector store.
Task: A Modern, Cross-Platform Build Tool for Streamlined Workflows
Task is an open-source, cross-platform build tool inspired by Make, designed to simplify and automate modern development workflows. It allows developers to define and run tasks using a simple YAML configuration, offering a powerful and intuitive alternative to traditional build systems. Written in Go, Task ensures fast execution and broad compatibility across various operating systems.
