A minimal Ruby gem for building agentic AI applications using the ReAct (Reasoning + Acting) loop pattern

A small Ruby CLI that answers questions about a knowledge-brain vault. Retrieval shells out to the hitgate `rag-query` CLI (JSON mode, argv-array, no shell interpolation); the chat is RubyLLM, with retrieved chunks injected as context and cited in the reply.

Envoy is a mountable Rails engine for governed, tool-calling agent chat: a DSL for host-owned toolsets, guard hooks for authorizing every tool call, persisted conversations, and a debug console.

A Ruby gem for identifying birds from photos and audio using RubyLLM. Adds multi-modal identification, location-aware results, multi-model consensus, and a Rails integration.

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.

Automatically generates Claude Code SKILL.md files from a gem's README, RubyDoc, and changelog. Skills are cached in ~/.gem/skills and symlinked into projects driven by Gemfile.lock. Provides both 'gem skill' and 'bundle skill' subcommands.

Define a safe component catalog, expose it as a RubyLLM tool schema, validate model-generated component trees, and render them with Rails partials, ViewComponent, or JSON.
