Calls go straight to the provider — no proxy. Includes budgets that can block the next call, bundle...

Nukitori is a Ruby gem for HTML data extraction. It uses an LLM once to generate reusable XPath schemas, then extracts structured data from similarly structured pages using plain Nokogiri. This makes scraping fast, predictable, and cheap for repeated runs.

Pocketrb is a Ruby AI agent framework featuring async message bus architecture, multi-LLM support (Claude, OpenRouter, RubyLLM), multi-channel messaging (CLI, Telegram, WhatsApp), planning system, context compaction, and simple JSON-based memory with keyword matching.
