Workflow

1. Initialize

   • Spawn speckit-runner agent (Opus)
   • Check for existing constitution
   • Determine starting phase

2. Phase 0: Constitution

   • Check for .constitution.md
   • If missing, create with project principles
   • Validate constitution structure

3. Phase 1: Specify

   • Invoke spec-generator agent
   • Generate canonical specification
   • Validate with spec-validator
   • Gate: INVEST score ≥ 7

4. Phase 2: Plan

   • Analyze codebase
   • Generate implementation design
   • Map design to requirements
   • Gate: All requirements covered

5. Phase 3: Tasks

   • Break into vertical slices
   • Generate task breakdown
   • Map tasks to requirements
   • Gate: All requirements have tasks

6. Phase 4: Implement

   • Execute tasks in order
   • Validate acceptance criteria
   • Run tests
   • Gate: All ACs pass

7. Complete

   • Generate completion report
   • Update specification status
   • Archive workflow artifacts

Arguments

• $ARGUMENTS - Feature request description
• --resume - Resume from last checkpoint
• --phase - Start from specific phase (0-4)
• --skip-constitution - Skip Phase 0 if constitution exists

Examples

# Full workflow from feature request
/spec-driven-development:speckit-run "User authentication with email and OAuth"

# Resume interrupted workflow
/spec-driven-development:speckit-run --resume

# Start from Phase 2 (existing spec)
/spec-driven-development:speckit-run --phase 2 .specs/auth/spec.md

# Skip constitution check
/spec-driven-development:speckit-run "New feature" --skip-constitution

Progress Tracking

The runner maintains checkpoints:

## Spec Kit Workflow: user-auth

**Started:** 2024-01-15T09:00:00Z
**Status:** Phase 2 - Plan

### Progress

| Phase | Status | Started | Completed |
| --- | --- | --- | --- |
| 0. Constitution | ✓ Complete | 09:00 | 09:02 |
| 1. Specify | ✓ Complete | 09:02 | 09:15 |
| 2. Plan | 🔄 In Progress | 09:15 | - |
| 3. Tasks | ⏳ Pending | - | - |
| 4. Implement | ⏳ Pending | - | - |

### Artifacts

- Constitution: .constitution.md ✓
- Specification: .specs/user-auth/spec.md ✓
- Design: .specs/user-auth/design.md (in progress)
- Tasks: pending

Validation Gates

Each phase has quality gates:

Phase	Gate Criteria
Constitution	File exists, required sections present
Specify	Schema valid, EARS format, INVEST ≥ 7
Plan	All requirements addressed, components defined
Tasks	All requirements have tasks, < 1 day each
Implement	All ACs pass, tests pass

Rollback Support

If a phase fails:

## Rollback Required

**Phase:** 2 (Plan)
**Reason:** Design does not cover FR-3

### Options

1. [Retry] Re-run Phase 2 with updated context
2. [Rollback] Return to Phase 1 and update spec
3. [Skip] Mark FR-3 as out-of-scope and continue

Completion Report

# Spec Kit Workflow Complete

**Feature:** User Authentication
**Duration:** 09:00 - 11:30 (2h 30m)
**Status:** ✓ SUCCESS
