parallel-development-expert_skill

Overview

This skill provides expert guidance for parallel development workflows using git worktrees and multi-agent execution. It helps identify independent tasks, estimate parallel vs sequential effort, and produce actionable plans to run features concurrently with Contextune. Use it to cut development time and reduce context costs with isolated worktrees and automated agent orchestration.

How this skill works

The skill analyzes a set of user tasks to determine independence by checking touched files, modules, and dependencies. For 2+ independent tasks it recommends using separate git worktrees and one agent per task, estimates time savings, and offers automated commands to plan, execute, monitor, and clean up. When tasks are dependent or conflict on the same files, it explains why parallelization isn’t recommended and proposes a sequential order.

When to use it

• You have multiple independent features or components to build (e.g., auth, dashboard, API).
• You want to speed up delivery or scale team throughput across concurrent work.
• You need guidance on using git worktrees to avoid conflicts and enable isolation.
• You want an estimated comparison of sequential vs parallel development time.
• You need automated orchestration to run tasks in isolated environments with multiple agents.

Best practices

• Verify tasks do not modify the same files or share mutable state before parallelizing.
• Break work into clear, independent units (modules, services, or feature branches).
• Use one git worktree per task to isolate changes and reduce merge conflicts.
• Prefer parallelization for 3+ independent tasks to maximize time and cost savings.
• Plan merges and integration tests up front to avoid late conflicts during cleanup.

Example use cases

• Three separate features (auth, UI dashboard, third-party API) running in parallel worktrees to cut delivery time by 50–70%.
• A small team splitting independent microservices across agents to accelerate sprint completion.
• Converting a long sequential roadmap into parallel subplans to shorten lead time and iterate faster.
• Answering questions about git worktree commands, setup, and safe cleanup when merging parallel branches.
• Estimating savings: provide sequential vs parallel hours and percent faster when 3+ independent tasks are detected.
