parallel-task — Claude Code skill: task orchestration and setup

This skill reads a development plan and assigns ready tasks to subagents in parallel. Use it to follow task dependencies and keep progress recorded in the plan.

What parallel-task does

The skill parses a Markdown plan into tasks, including their IDs, requirements, validation steps, and dependencies. You can request selected task IDs; their prerequisites are included too. Without a selection, it works through the whole plan. Tasks whose dependencies are complete are launched together, in waves.

For suitable tasks, the workflow starts with a subagent writing tests and showing that they fail, then moves to implementation and passing checks. If a task is not a good fit for TDD, the agent records why and defines another concrete verification method. Once checks pass, the agent commits locally and updates the plan; the orchestrator reviews the result and can request another attempt. A task needs verification evidence, a commit, and a plan update before it counts as done.

For Claude Code, installation places the skill at ~/.claude/skills/parallel-task/SKILL.md. Start it explicitly with /parallel-task, followed by a plan path and optional task IDs. The workflow permits local commits, not pushes.

What it helps with

  • Run independent plan tasks at the same time
  • Include prerequisites when selecting specific task IDs
  • Verify acceptance criteria with tests or another defined check
  • Record task results in the plan after committing

Example prompts for the agent

  • Use /parallel-task to carry out the development plan in plan.md.
  • Run T1, T2, and T4 from ./plans/auth-plan.md with /parallel-task.
  • Have /parallel-task work on T3 and T7 from user-profile-plan.md only.

Questions about parallel-task

How do I install parallel-task in Claude Code?

Run npx skills add am-will/codex-skills --skill parallel-task -a claude-code. The skill file is at ~/.claude/skills/parallel-task/SKILL.md.

What does parallel-task do?

It reads a task plan, delegates work to subagents, and schedules tasks according to their dependencies. It also checks results and records completed work in the plan.

How does parallel-task handle task dependencies?

It launches tasks only when their dependencies are complete. After each wave is checked and committed locally, it finds the next tasks that are ready.
