A standalone, self-contained coding and automation agent built on ruby_llm. Provides an agent loop, persistent memory, SQLite sessions, context compaction, a job system, a tool registry, and an extensible UI layer.

A Rails engine providing comprehensive observability for LLM-powered applications. Features include session tracking, trace analysis, prompt management, cost monitoring, and optional chat/agent testing UI (with RubyLLM integration).

ruby_llm-toolbox bundles filesystem, shell, web, git, and data tools as ready-to-use RubyLLM::Tool subclasses. One require loads everything; read-only tools are on by default while mutating/exec tools are gated behind explicit config. Tool output is token-budgeted via ruby_llm-tokenizer.

Ruby Maat is a command line tool used to mine and analyze data from version-control systems (VCS). This is a Ruby port of the original Clojure Code Maat.

Ruby Scientist and Graphics is a practical data science toolkit for Ruby. It includes a lightweight built-in DataFrame for loading, cleaning, and transforming data; quick descriptive statistics and correlations; charting via Gruff (bar and line); and simple ML utilities (linear regression and k-means)—all behind a small, unified, pandas-inspired API. Key features: - Load data from CSV and JSON. - Clean and transform (remove/add columns, handle missing values, limit rows). - Describe datasets and compute correlations quickly. - Create bar and line charts with customization options. - Train/predict with linear regression; cluster with k-means. - Save/load project state (data + trained model) and run simple pipelines. - Optional backend adapters (e.g., Rover) while keeping the same API. Ideal for analysts and developers who want to explore data in Ruby without relying on Python or R. Note: plotting via Gruff uses rmagick, which requires ImageMagick installed on the system.

A configurable lint engine for SAS source files. Walks the token stream produced by the `sas-lexer` gem and applies a set of pluggable rules covering structural defects (malformed `if` conditions, identical `then`/`else` branches, unreachable inner branches), cosmetic issues (trailing whitespace, tab expansion, line endings, encoding gremlins), and source-header conventions. Includes a `bin/sas_lint` CLI and YAML-based config.

Scout gear: workflow, TSVs, persistence, entities, associations, and knowledge_bases.

Helpers for writing command line scripts. An extraction from Dwellable.

Every sea port UNECE publishes a UN/LOCODE for, as a lookup table with no dependencies and no network calls. Turns the bare codes in an AIS or carrier tracking feed back into port names and coordinates. The table is regenerated from each UN/LOCODE release and shipped inside the gem.
