Build Workflow

Plan and implement features with proper testing.

Usage

/build "user authentication with JWT"
/build greenfield "new dashboard component"
/build brownfield "add caching to existing API"
/build tdd "implement retry logic"

Modes

Mode	When to Use
greenfield	New feature from scratch
brownfield	Modifying existing code
tdd	Test-driven development

Default: Infers from context (new files = greenfield, existing = brownfield)

Workflow Chain

Phase 1: Planning (architect)

Spawn the architect agent to plan:

Use Task tool:
  subagent_type: "architect"
  prompt: "Plan implementation: $DESCRIPTION

  1. Analyze requirements
  2. Research existing patterns in codebase
  3. Design the solution architecture
  4. Create implementation plan with:
     - Files to create/modify
     - Key components
     - Data flow
     - Dependencies
  5. Identify risks and edge cases"

Phase 2: Implementation (kraken)

Spawn kraken to implement:

Use Task tool:
  subagent_type: "kraken"
  prompt: "Implement the plan from architect:

  Plan: [from architect]

  Follow TDD approach:
  1. Write tests first (for testable components)
  2. Implement to make tests pass
  3. Refactor for clarity
  4. Document key decisions"

Phase 3: Testing (arbiter)

Spawn arbiter to verify:

Use Task tool:
  subagent_type: "arbiter"
  prompt: "Verify implementation:

  1. Run all new tests
  2. Run related existing tests
  3. Check code coverage
  4. Verify requirements are met
  5. Report any gaps"

Phase 4: Review (judge) - Optional

For significant changes, spawn judge:

Use Task tool:
  subagent_type: "judge"
  prompt: "Review the implementation:

  1. Code quality check
  2. Pattern adherence
  3. Security review
  4. Performance considerations
  5. Suggestions for improvement"

Options

Option	Effect
--skip-plan	Skip planning phase (have clear spec)
--skip-review	Skip review phase
--no-commit	Don't auto-commit
--parallel	Run research in parallel

Output

After completion:

• Summary of what was built
• Files created/modified
• Test coverage
• Any follow-up items
