spindle

Persistent JavaScript REPL for orchestration — async subagents in tmux sessions, file I/O, tool wrappers, MCP server integration. Use when chaining operations, spawning parallel agents, calling MCP tools, or transforming data programmatically.

Execute a plan autonomously using sub-agent loops in spindle. Takes a plan (markdown task list, kanban board, or scratchpad plan), parses it into tasks, and loops sub-agents over them with review cycles and git-backed state. Use when asked to "work through this plan", "ralph over this", "autopilot", "execute this plan autonomously", or "loop over these tasks".
