I archived Claude Copilot this spring. It deserves a proper goodbye instead of a quiet repo archive button, so here it is. Copilot started as an extension of an open source framework, back when Claude Code was newer and I kept hitting the same walls: one agent, one repo, no memory between sessions. So I built around the walls. An orchestrator-worker pattern that could coordinate work across multiple repositories at once. Thirteen specialized agents with actual roles: architect, engineer, QA, security, DevOps, UX, and friends. Parallel streams of work with conflict detection between them, git worktrees keeping the agents out of each other’s way, and persistent memory in PostgreSQL so a session could pick up where the last one stopped. Node.js and Python glue, the Claude Code API underneath.
