fizzy-cli

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.

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.

claude-founder-playbook organizes a startup idea into Idea, MVP, Launch, and Scale stages, each with question sets, document templates, and exit criteria. Its CLI can initialize a project, show status, and advance only when the checklist and red-team challenge are complete; unresolved decisions stay visible instead of being silently guessed. English and Chinese templates are included.
