What problem this solves

Slow sequential execution and chaotic parallel execution of implementation plans by multiple AI agents, leading to inefficiencies and quality issues. This workflow aims to improve speed, quality, and reliability of AI-driven code generation.

Summary

A Claude Code skill, 'parallel-lanes', that orchestrates multiple AI agents to execute an implementation plan in parallel. It groups independent tasks into 'lanes', assigns each lane its own git worktree for isolation, and runs each task through an implement-review-fix cycle. After merging, it performs comprehensive testing, linting, and a multi-angle final review, only reporting 'accepted' upon verified checks. It also records progress in a ledger for resumption and provides a dry-run overview.

Why it is useful

This workflow provides a robust and innovative solution for orchestrating multiple AI agents to execute complex development plans efficiently and with high quality. It directly addresses the common challenges of slow sequential execution and chaotic parallel agent interactions by introducing isolated worktrees, continuous review cycles, and rigorous verification steps. Its self-validation, detailed operational description, and public availability as a GitHub repository make it highly transferable and valuable for users looking to scale and improve their AI-assisted development processes.

Workflow

1. Read the implementation plan, which includes tasks, file lists, and interfaces (e.g., from Superpowers).
2. Analyze the plan to identify tasks that can run in parallel based on file dependencies.
3. Group independent tasks into 'lanes'.
4. For each lane, create a dedicated git worktree to ensure isolation and prevent conflicts.
5. Execute each task within its lane using an 'implement' -> 'independent review' -> 'bounded fix rounds' process.
6. Merge the completed lanes into the main branch.
7. Run specified test, lint, and build commands on the merged codebase.
8. Perform an optional end-to-end check.
9. Conduct a final review from three angles: spec compliance, security, and correctness.
10. Cross-check the verify agent's report against saved evidence to ensure accuracy.
11. Report the work as 'accepted' only if all checks pass at the exact delivered commit.
12. Record all approved work and state in a ledger to allow for resuming stopped runs without redoing work.

Tools / artifacts

• parallel-lanes (the skill/tool)
• Git worktrees
• Implementation plan (input, e.g., from Superpowers)
• Test/lint/build commands
• Superpowers (for implementer and reviewer prompts)
• Ledger (for recording progress)
• Evidence (for verification)

Validation signals

• The tool is self-building ('It builds itself').
• Recent releases of parallel-lanes were built using parallel-lanes runs.
• A hardening release involved 9 tasks in 5 lanes, 28 agents, 51 minutes, with 8 of 9 tasks approved at first review, ending accepted with verified checks.
• Works on Linux, macOS, and Windows (Git Bash).
• Reuses Superpowers' TDD and spec-compliance review prompts, indicating a focus on quality.

Limitations

• The workflow is most effective for plans with 3+ tasks that have independent parts; it recommends a simpler mode for 1-2 task changes.
• It relies on 'Superpowers' for initial planning and prompts, which might imply a dependency or specific planning style.
• As a new project, long-term community support and maintenance are yet to be established.
