Cruise Control Mode 🚗💨

Automatic transmission for StackShift – Shift through all 6 gears sequentially without manual intervention.

When to Use This Skill

Use cruise control when:

• You want to run the entire workflow automatically
• Don’t need to review each step before proceeding
• Trust StackShift to make reasonable defaults
• Want unattended execution (kick it off and come back later)
• Prefer automatic over manual transmission

Trigger Phrases:

• “Run StackShift in cruise control mode”
• “Automatically shift through all gears”
• “Run the full workflow automatically”
• “StackShift autopilot”

What This Does

Runs all 6 gears sequentially:

Gear 1: Analyze → Gear 2: Reverse Engineer → Gear 3: Create Specs →
Gear 4: Gap Analysis → Gear 5: Complete Spec → Gear 6: Implement

Without stopping between gears!

Setup

Initial Configuration (One-Time)

At the start, you’ll be asked:

1. Route Selection:

   Choose your route:
   A) Greenfield - Shift to new tech stack
   B) Brownfield - Manage existing code
   

2. Clarifications Handling:

   How to handle [NEEDS CLARIFICATION] markers?
   A) Defer - Mark them, implement around them, clarify later
   B) Prompt - Stop and ask questions interactively
   C) Skip - Only implement fully-specified features
   

3. Implementation Scope:

   What to implement in Gear 6?
   A) P0 only - Critical features only
   B) P0 + P1 - Critical and high-value
   C) All - Everything (may take hours/days)
   D) None - Stop after specs are ready
   

Then cruise control takes over!

Execution Flow

Gear 1: Analyze (Auto)

• Detects tech stack
• Assesses completeness
• Sets route (from your selection)
• Saves state with auto_mode: true
• Auto-shifts to Gear 2 ✅

Gear 2: Reverse Engineer (Auto)

• Launches stackshift:code-analyzer agent
• Extracts documentation based on route
• Generates all 9 files (including integration-points.md)
• Auto-shifts to Gear 3 ✅

Gear 3: Create Specifications (Auto)

• Calls automated spec generation (F002)
• Generates constitution (appropriate template for route)
• Creates all feature specs programmatically
• Creates implementation plans for incomplete features
• Sets up /speckit.* slash commands
• Auto-shifts to Gear 4 ✅

Gear 4: Gap Analysis (Auto)

• Runs /speckit.analyze
• Identifies PARTIAL/MISSING features
• Creates prioritized roadmap
• Marks [NEEDS CLARIFICATION] items
• Auto-shifts to Gear 5 ✅

Gear 5: Complete Specification (Conditional)

• If clarifications handling = “Defer”: Skips, moves to Gear 6
• If clarifications handling = “Prompt”: Asks questions interactively, then continues
• If clarifications handling = “Skip”: Marks unclear features as P2, moves on
• Auto-shifts to Gear 6 ✅

Gear 6: Implement (Based on Scope)

• If scope = “None”: Stops, specs ready
• If scope = “P0 only”: Implements critical features only
• If scope = “P0 + P1”: Implements critical + high-value
• If scope = “All”: Implements everything
• Uses /speckit.tasks and /speckit.implement for each feature
• Completes! 🏁

Progress Monitoring

While cruise control is running, you can check progress:

# See current gear
node plugin/scripts/state-manager.js status

# Detailed progress
node plugin/scripts/state-manager.js progress

# Watch progress in real-time
watch -n 5 'node plugin/scripts/state-manager.js progress'

Or via MCP resource:

Read stackshift://progress

Interrupting Cruise Control

You can stop cruise control at any time:

"Stop cruise control"
"Pause StackShift"
"Switch to manual mode"

This will:

• Save current state
• Set auto_mode: false
• Allow you to proceed manually from current gear

You can resume cruise control later:

"Resume cruise control from current gear"

Example: Full Automatic Run

User: "Run StackShift in cruise control mode"

StackShift:
Setting up cruise control...

Choose your route:
A) Greenfield - Shift to new tech stack
B) Brownfield - Manage existing code

User: "B - Brownfield"

StackShift:
How to handle clarifications?
A) Defer - Clarify later
B) Prompt - Ask me now
C) Skip - Only implement clear features

User: "A - Defer"

StackShift:
Implementation scope?
A) P0 only
B) P0 + P1
C) All features
D) None (stop after specs)

User: "B - P0 + P1"

StackShift:
✅ Cruise control engaged! Shifting through all gears automatically...

🔍 Gear 1: Analyzing... ✅ Complete (2 min)
🔄 Gear 2: Reverse engineering... ✅ Complete (8 min)
📋 Gear 3: Creating specifications... ✅ Complete (5 min)
🔍 Gear 4: Gap analysis... ✅ Complete (3 min)
✨ Gear 5: Completing specs (deferred clarifications)... ✅ Complete (1 min)
🚀 Gear 6: Implementing P0 + P1 features... 🔄 In Progress (est. 45 min)

   Feature 1/8: user-authentication... ✅
   Feature 2/8: fish-management... ✅
   Feature 3/8: photo-upload... 🔄 In progress...

[... continues automatically ...]

🏁 All gears complete! Application at 85% implementation.

Deferred clarifications (3) saved in: .specify/memory/clarifications.md
You can resolve these later with: /speckit.clarify

Configuration Options

Cruise control can be configured via state:

{
  "auto_mode": true,
  "auto_config": {
    "route": "brownfield",
    "clarifications_strategy": "defer",
    "implementation_scope": "p0_p1",
    "pause_between_gears": false,
    "notify_on_completion": true
  }
}

Advanced: Scheduled Execution

Run cruise control in background:

# Start in background
nohup stackshift cruise-control --route brownfield --scope p0 &

# Check progress
tail -f stackshift-cruise.log

# Or via state
watch stackshift://progress

Use Cases

1. Overnight Execution

5pm: "Run cruise control, brownfield, P0+P1, defer clarifications"
9am: Check results, review generated specs, answer deferred questions

2. CI/CD Integration

# .github/workflows/stackshift.yml
- name: Run StackShift Analysis
  run: stackshift cruise-control --route brownfield --scope none
  # Generates specs, doesn't implement (safe for CI)

3. Batch Processing

Run cruise control on multiple projects:
- project-a: greenfield
- project-b: brownfield
- project-c: brownfield

4. Demo Mode

"Show me what StackShift does - run full demo"
→ Runs cruise control with sample project

Safety Features

Checkpoints

Cruise control creates checkpoints at each gear:

• State saved after each gear completes
• Can resume from any checkpoint if interrupted
• Rollback possible if issues detected

Validation

Before proceeding:

• Validates output files were created
• Checks for errors in previous gear
• Ensures prerequisites met

User Intervention

Pauses automatically if:

• Critical error detected
• /speckit.analyze shows major inconsistencies
• Implementation fails tests
• Disk space low
• Git conflicts detected

Manual Override

At any point, you can:

"Pause after current gear"
"Stop cruise control"
"Switch to manual mode"
"Take control"

State saved, you can continue manually from that point.

Success Criteria

After cruise control completes:

• ✅ All 6 gears complete
• ✅ .stackshift-state.json shows 6/6 gears
• ✅ All output files generated
• ✅ GitHub Spec Kit initialized
• ✅ Features implemented (based on scope)
• ✅ Ready for production (or clarifications if deferred)

Technical Notes

• Cruise control is a special skill that orchestrates other skills
• Each gear is still executed by its corresponding skill
• Auto mode can be toggled on/off at any time
• State tracks auto_mode for resume capability
• Great for CI/CD, batch processing, or overnight runs

Remember: Cruise control is like automatic transmission – convenient and hands-off. Manual mode (using individual skills) gives you more control. Choose based on your needs!

🚗 Manual = Control each gear yourself 🤖 Cruise Control = Let StackShift handle it

Both get you to the same destination!
