RLM.rb is a Ruby runtime spine for Recursive Language Models. It runs bounded, typed, auditable AI jobs over files, records, and application context. RLM.rb includes RubyLLM provider access, a dspy.rb signature adapter, the recursive prompt loop, file/context mounting, recursive sub-LM calls, typed final output, budget controls, trace events, and a best-effort trace_store hook.

A lenient, fast JSON processor for Ruby. It extracts strict JSON, NDJSON, JSONL, JSON5, HJSON-style config, and the messy JSON-ish input humans and LLMs actually write — comments, trailing commas, single / unquoted / smart quotes, Python and JS keywords, a UTF-8 BOM, and more all parse to the same Ruby objects, with no modes or flags to set. Where a traditional parser stops at the first deviation and throws away the whole document, SmarterJSON keeps going — it optimizes for getting your data out, not for policing the JSON spec. It reads multi-document NDJSON / JSONL in one call (and streams it with a block), and in benchmarks its C extension matches or beats Oj on nearly every file. SmarterJSON is opinionated: we want your JSON processing to be successful.
