And-Then

Sequential task queue with parallel fork support for Claude Code.

Features

• Sequential tasks (--task): Execute tasks one at a time
• Parallel fork tasks (--fork): Spawn multiple subagents concurrently
• Auto-completion: Tasks advance automatically when you output <done/>
• Dynamic additions: Add tasks while queue is running

Usage

# Sequential tasks
/and-then --task "Build the API" --task "Write tests" --task "Update docs"

# Mix sequential and parallel tasks
/and-then --task "Build the API" \
          --fork "Unit tests" "Integration tests" "E2E tests" \
          --task "Deploy to staging"

Commands

Command	Description
/and-then	Create a new task queue
/and-then-add	Add tasks to existing queue
/and-then-skip	Skip current task
/and-then-status	Show queue progress
/and-then-cancel	Cancel the queue

How It Works

1. Queue stored in .claude/and-then-queue.local.md
2. Work on current task
3. Output <done/> when complete
4. Stop hook advances to next task
5. For forks: launch parallel subagents, wait for all, then <done/>

Examples

Parallel Testing Pipeline

/and-then --task "Build the application" \
          --fork "Run unit tests" "Run integration tests" "Run linting" \
          --task "Deploy to staging"

Research-Then-Implement

/and-then --fork "Research auth libraries" "Review security requirements" \
          --task "Implement authentication" \
          --task "Write tests"
