description	Split feature into independent subtasks and execute in parallel

Parallel Task Execution

Split a feature into independent subtasks and execute them in parallel with multiple agents.

Prerequisites

• Tasks must be independent of each other (no shared files)
• Best suited for greenfield projects or clearly separated areas
• For existing code: beware of merge conflict risk

Workflow

1. Analyze and split the feature

Identify independent subtasks. Example for a new feature "Trade Export":

Task	Files	Independent?
API types + mock handler	src/api/	Yes
Export button component	src/components/ExportButton.tsx	Yes
Export hook	src/hooks/useExport.ts	Depends on types
Tests	src/test/export.test.tsx	Depends on everything

2. Start independent tasks in parallel

Start agents using the Agent tool with isolation: "worktree":

Agent 1 (worktree): "Create API types and mock handler for trade export"
Agent 2 (worktree): "Create ExportButton component with shadcn/ui"

3. Merge results

• Review and merge worktree branches
• Implement dependent tasks (hook, tests) sequentially afterwards

When NOT to parallelize

• Small features (< 1 hour of work) - overhead not worth it
• Tightly coupled code - merge conflicts eat up the time savings
• Existing legacy codebase - too many implicit dependencies
