Verquest describes API request bodies, query strings and path parameters with a Ruby DSL, one definition per API version. It validates params against JSON Schema, maps them from your public API structure to your internal one, and generates JSON Schema components and OpenAPI parameters for documentation tools like rswag.

This gem contains Wisp's JSON schema definition

Abstraction to help work with A2A protocol

AgentHarness provides a unified interface for CLI-based AI coding agents like Claude Code, Cursor, Gemini CLI, and others. It offers full orchestration with provider switching, circuit breakers, health monitoring, flexible configuration, dynamic provider registration, and token usage tracking.

Ruby server implementation of the AG-UI protocol (SSE event streaming, run loop, client-tool round-trips, A2UI) for driving CopilotKit frontends from Rack/Falcon.

Provider-agnostic guardrails (PII redaction, schema validation) and evaluation/regression harness for LLM prompts and models.

The app_bridge gem is designed to enable seamless interaction with WebAssembly components that adhere to the WIT specification `standout:app`. It is developed for use in Standout's products.

AsciiChem is an ASCII syntax for representing chemical formulae, reactions, electron configurations, bonds, crystals, spectra, calculations, Z-matrices, and reaction mechanisms. It parses to a semantic model and renders to MathML, HTML, LaTeX, SVG, and CML. Math embedding uses Plurimath. Round-trips to native CML via chemicalml.

LutaML model definitions and versioned JSON Schemas that every AsciiChem implementation (Ruby, TypeScript, Python) conforms to.

The AG-UI (Agent-User Interaction) protocol server for the ask-rb ecosystem — SSE event streaming and the runtime surface that assistant-ui and CopilotKit frontends expect.

AsyncAPI Cable adds an AsyncAPI 3 DSL on top of Rails ActionCable. It generates an AsyncAPI document for your channels, sharing JSON Schema components with OpenAPI tooling, and validates broadcast and transmit payloads against declared message schemas at runtime.

Async-native Matrix protocol primitives built on the Socketry async ecosystem. A resource-oriented client for every Matrix API, version by version, with schema-validated events, media and end-to-end encryption.

Belay records every model and tool call as a Postgres row, so an AI workflow that crashes partway resumes from its last checkpoint instead of starting over.

Ruby gem and command-line utility for conversion of DOI metadata from and to different metadata formats, including schema.org. Fork of version 1.19.12 of the bolognese gem.

A Ruby implementation of the Broadlistening pipeline for clustering and analyzing public comments using LLM

Production-grade coding agent with tool execution, middleware pipeline, context compaction, session persistence, and multi-provider LLM support.

Automation steps and mock server to validaterequest payloads response.

chocomint は LLM のツール呼び出しを Ruby 側で厳格に監督するオーケストレータ。 機械的検証・意味的検証・自動再試行・監査ログを行い、LLM は提案者と監査者に限定し、 実行・判定・再試行・記録は Ruby が責任を持つ。Anthropic Messages API 互換の 監督プロキシサーバーと、ブラウザ上の AI エディタ (/edit) も提供する。

Base controller, model, resource and policy classes; authentication with JWT, per request tenant selection, exception reporting

Ruby gem and command-line utility for conversion of scholarly metadata from and to different metadata formats, including schema.org. Based on the bolognese gem, but using commonmeta as the intermediate format.
