FlowEngine provides a DSL for defining multi-step flows as directed graphs with conditional branching, an AST-based rule evaluator, and a pure-Ruby runtime engine. No framework dependencies.

Agents that write and execute Ruby code. Inspired by smolagents. LLMs write executable code, not JSON blobs.

Genie CLI is a command-line tool that brings Test Driven Development (TDD) principles to life by integrating with a large language model (LLM) through the ruby_llm library. It provides an interactive session to write tests, implement code, and manage your codebase.

RubyLLM provider for girb (AI-powered IRB assistant). Install this gem to use OpenAI, Anthropic, Gemini and other LLMs via RubyLLM as your LLM backend.

HTM (Hierarchical Temporal Memory) provides intelligent memory/context management for LLM-based applications. It implements a two-tier memory system with durable long-term storage (PostgreSQL) and token-limited working memory, enabling applications to recall context from past conversations using RAG (Retrieval-Augmented Generation) techniques.

A multi-language code generator to cope with Hyrum's law

Agents that write and execute Ruby code. Developers can build and distribute Agents as files or compiled jar files. Inspired by smolagents. LLMs write executable code, not JSON blobs.

An open-source, security-first AI agent framework in Ruby with capability-based permissions, sandboxed skills, and a layered prompt system.

Used in conjunction with the Language Operator for Kubernetes

Interact with PostgreSQL, MySQL, and Oracle databases using natural language. Powered by RubyLLM with a locally-running Ollama model.

A minimalist AI agent framework with multi-channel support, tool calling, and extensible architecture

Phronomy provides Agent, Workflow, Memory, Tool, Guardrail, RAG, and Multi-agent capabilities for building AI agents in Ruby and Rails. Powered by RubyLLM for LLM abstraction.

A library for assembling AI assistants: Pikuri::Agent (a thin wrapper around ruby_llm's chat loop), Pikuri::Tool with strict argument validation, a listener surface for rendering / budgets / sub-agents, and a small set of bundled tools (calculator, web search, web scrape, fetch, plus six coding tools: read / write / edit / grep / glob / bash). Downstream projects (notably the planned pikuri-tui) wire these into actual binaries. The repo also ships `bin/pikuri-chat` and `bin/pikuri-code` as demo entry points, but they are NOT installed by `gem install pikuri` — they exist to show how to wire the library together and to support development.

Probatio Diabolica runs custom *_spec.rb files with a DSL inspired by RSpec and supports text/image/PDF reporting.

Under development. Contributors welcome.

Ragents is a pure Ruby, Ractor-based AI agent framework designed for concurrent, isolated agent execution. It provides message-passing architecture, tool-based actions, and provider-agnostic LLM integration without Rails dependencies.

Unified tool definition pipeline for Rails 8 applications using FastMCP and RubyLLM.
