agx is an open-source coding agent harness and developer orchestration tool developed by ramarlina. It serves as a unified orchestration layer to coordinate tasks, repository context, and AI-driven workflows across command-line and desktop environments. Operating both as a background daemon and interactive CLI (with an accompanying desktop interface), agx coordinates local repository workspaces with external developer platforms. It manages multi-project contexts using a local SQLite persistence layer and handles integrations like GitHub pull request tracking, review interfaces, and task resolution from issue trackers like Linear. Unlike simple single-prompt wrapper scripts, agx is architected around structured workspace state, polymorphic link stores, and tracker resolvers. It decouples task management and PR review synchronizations from raw model interactions, allowing developers to import/export YAML workspace definitions and manage project environments consistently. agx is maintained as an open-source project on GitHub under active development, offering cross-platform CLI tools alongside notarized macOS desktop releases.
