The official Basecamp CLI lets users list projects, create and complete todos, search across workspaces, manage cards, files, chats, and comments, and emit structured JSON for automation. OAuth tokens refresh automatically, and the repository includes both a Claude plugin and a portable agent skill for shell-capable assistants.

fizzy-cli brings Fizzy boards, cards, comments, search, attachments, activity, and related administration into a terminal interface that shell-capable AI agents can also use. Commands return structured JSON with breadcrumbs that suggest useful follow-up actions, and the repository includes setup for a Claude plugin and embedded agent skill. Initial configuration requires a Fizzy personal access token and account selection, with an optional default board.

clu coordinates multiple AI coding agents through a local SQLite issue tracker and single-binary CLI. It supports atomic issue claims, capability routing, dependency graphs, checkpoints, locks, mailboxes, milestones, and inherited context, while keeping writes in a local log. There is no daemon, server, account, or network requirement, making it suited to agents sharing one machine.

linear-cli gives humans and agents the same shell workflow for listing queues, claiming issues, posting progress, and closing work with attached proof. The tool is a single Python file with no third-party runtime dependencies and offers JSON output for automation; it requires a Linear API key with the permissions needed for the requested actions.
