What problem does it solve?
Orchestrates parallel AI agent sessions across Claude Code, Codex, OpenCode, and other harnesses using dmux, a tmux pane manager, to reduce idle time and improve cross-harness productivity.
Core Features & Use Cases
- Pattern 1: Research + Implement — Split research and implementation into parallel tracks to accelerate learning and delivery.
- Pattern 2: Multi-File Feature — Parallelize work across independent files (docs, code, tests) with coordinated integration.
- Pattern 3: Test + Fix Loop — Run tests in one pane and implement fixes in another to shorten feedback cycles.
- Pattern 4: Cross-Harness — Use different tools for different tasks to optimize throughput (Claude Code, Codex, Claude Code Task tool, etc.).
- Pattern 5: Code Review Pipeline — Parallelize security, performance, and test-review perspectives and merge results into a single report.
- ECC Helper — External helper for git worktrees and tmux orchestration to plan and execute multi-pane sessions.
Quick Start
Start a dmux session and create parallel agent panes to run your tasks.
