Upgrading to Spec Kitty 0.11.0

⚠️ BREAKING CHANGE: Workspace model changed from workspace-per-feature to workspace-per-work-package

What Changed

Old model (0.10.x):

  • Planning commands created a single worktree per feature
  • All work packages shared the same worktree
  • Pattern: .worktrees/###-feature/

New model (0.11.0+):

  • Planning commands work in main repository (no worktree created)
  • Each work package gets its own worktree on-demand
  • Pattern: .worktrees/###-feature-WP##/
  • Enables parallel multi-agent development

Critical: Complete In-Progress Features First

You MUST complete or delete all in-progress features before upgrading to 0.11.0.

The migration will be blocked if you have legacy worktrees (0.10.x format) in your .worktrees/ directory.

Pre-Upgrade Checklist

Complete ALL items before upgrading:

☐ Step 1: Check for Legacy Worktrees

ls .worktrees/

Look for directories matching pattern ###-feature (without -WP## suffix).

Examples of legacy worktrees:

  • 008-unified-python-cli/ ← Legacy (0.10.x)
  • 009-improved-documentation/ ← Legacy (0.10.x)
  • 010-workspace-per-wp-WP01/ ← New (0.11.0+, this is OK)

Or use the utility command (after upgrading spec-kitty-cli):

pip install --upgrade spec-kitty-cli  # Get 0.11.0 first
spec-kitty list-legacy-features       # Then check for legacy worktrees

Note: The list-legacy-features command is new in 0.11.0. If you're on 0.10.x, use ls .worktrees/ to manually check for legacy worktrees before running spec-kitty upgrade.

☐ Step 2: Decide What to Do With Each Feature

For each legacy worktree, choose one:

  • Option A: Complete the feature (recommended)
  • Option B: Delete the feature (if abandoning)

☐ Step 3: Complete or Delete Features

Option A: Complete features (recommended)

For each feature you want to keep:

# 1. Review what's in the worktree
cd .worktrees/008-unified-python-cli/
git status
git log --oneline

# 2. Make sure all work is committed
git add .
git commit -m "Final changes before merge"

# 3. Go back to main repo
cd /path/to/main/repo

# 4. Merge the feature
spec-kitty merge 008-unified-python-cli

Repeat for each legacy feature.

Option B: Delete features (if abandoning)

For features you want to discard:

# 1. Remove the worktree
git worktree remove .worktrees/008-unified-python-cli

# 2. Delete the branch
git branch -D 008-unified-python-cli

# 3. Optionally clean up feature artifacts in main
rm -rf kitty-specs/008-unified-python-cli
git add kitty-specs/
git commit -m "Remove abandoned feature 008"

⚠️ Warning: Deleting a feature is permanent. Make sure you don't need the code before deleting.

☐ Step 4: Verify Clean State

After completing or deleting all features:

ls .worktrees/
# Should be empty OR only show ###-feature-WP## patterns (new format)

If you still see legacy worktrees (directories without -WP## suffix), go back to Step 3 and handle them.

After upgrading spec-kitty-cli to 0.11.0, you can also verify with:

spec-kitty list-legacy-features
# Should show: "No legacy worktrees detected"

☐ Step 5: Backup (Optional but Recommended)

Before upgrading, back up your repository:

# Create a backup branch
git checkout -b backup-before-0-11-0
git push origin backup-before-0-11-0

# Go back to main
git checkout main

☐ Step 6: Read Breaking Changes

Review what changed in 0.11.0:

  • Planning commands no longer create worktrees
  • New command: spec-kitty implement WP##
  • Dependency tracking in WP frontmatter
  • All 12 agent templates updated

See Workspace-per-WP documentation for details.

☐ Step 7: Upgrade

pip install --upgrade spec-kitty-cli
spec-kitty --version  # Should show 0.11.0

If the upgrade is blocked with error message:

❌ Cannot upgrade to 0.11.0
Legacy worktrees detected:
  - 008-unified-python-cli

Go back to Step 3 and complete/delete the listed features.

☐ Step 8: Verify Upgrade

Test the new workflow with a dummy feature:

# Planning now works in main (no worktree created)
/spec-kitty.specify "Test Feature"

# Check that NO worktree was created
ls .worktrees/
# Should still be empty

# Check that spec was created in main
ls kitty-specs/
# Should show 012-test-feature/ (or next available number)

# Check git log
git log --oneline
# Should show: "Add spec for feature 012-test-feature"

# Clean up test feature

**⚠️ Warning**: Choose a safe cleanup method:

**Option A: Safer - Explicit revert (recommended)**
```bash
rm -rf kitty-specs/012-test-feature
git add kitty-specs/
git commit -m "Remove test feature 012-test-feature"

Option B: Revert the commit

git revert HEAD  # Reverts the test feature commit
# Creates new commit that undoes the test

Option C: Hard reset (⚠️ DESTRUCTIVE - only if you're sure)

# WARNING: This permanently deletes the commit. Only use if:
#  - The test feature commit has NOT been pushed to remote
#  - You have no other unpushed commits you want to keep
#  - You're absolutely sure you don't need the test

git reset --hard HEAD~1
# ⚠️ Cannot be undone!

Recommended: Use Option A or B. They're safer and create a clear history.


**Success!** You're now on 0.11.0.

## What's Different After Upgrading

### Planning Commands (Now in Main)

**Before (0.10.x)**:
```bash
/spec-kitty.specify "My Feature"
→ Created .worktrees/010-my-feature/
→ You work inside the worktree

After (0.11.0):

/spec-kitty.specify "My Feature"
→ Creates kitty-specs/010-my-feature/spec.md in main
→ Commits to main
→ NO worktree created
→ You stay in main repository

Same for /spec-kitty.plan and /spec-kitty.tasks.

Implementation Command (New)

Before (0.10.x):

# Agents work in shared worktree created during planning
cd .worktrees/010-my-feature/
# All WPs implemented here

After (0.11.0):

# Create worktree for specific WP
spec-kitty implement WP01
→ Creates .worktrees/010-my-feature-WP01/
→ Agent A works here

# Create worktree for another WP (parallel!)
spec-kitty implement WP02
→ Creates .worktrees/010-my-feature-WP02/
→ Agent B works here simultaneously

Dependencies (New Feature)

Work packages can now declare dependencies in frontmatter:

---
work_package_id: "WP02"
title: "API Endpoints"
dependencies: ["WP01"]  # WP02 depends on WP01
---

Implement with dependencies:

spec-kitty implement WP02 --base WP01
# WP02 branches from WP01's branch, includes WP01's changes

New Commands in 0.11.0

spec-kitty implement WP## [--base WPXX]

Create worktree for a specific work package.

Usage:

# Independent WP (branches from main)
spec-kitty implement WP01

# Dependent WP (branches from another WP)
spec-kitty implement WP02 --base WP01

What it does:

  1. Creates .worktrees/###-feature-WP##/ directory
  2. Creates git branch ###-feature-WP##
  3. Checks out code in the worktree
  4. Moves WP from planned → doing lane

spec-kitty list-legacy-features

Check for legacy worktrees before upgrading.

Usage:

spec-kitty list-legacy-features

Output examples:

# No legacy worktrees
No legacy worktrees detected. Safe to upgrade to 0.11.0.

# Legacy worktrees found
Legacy worktrees detected:
  - 008-unified-python-cli
  - 009-improved-documentation

Complete or delete these features before upgrading to 0.11.0.

Updated Commands in 0.11.0

/spec-kitty.specify

Before: Created worktree After: Works in main, commits spec.md to main, NO worktree created

/spec-kitty.plan

Before: Worked in worktree After: Works in main, commits plan.md to main

/spec-kitty.tasks

Before: Worked in worktree After: Works in main, commits tasks/*.md to main, generates dependencies in frontmatter

spec-kitty merge

Before: Merged single feature branch After: Merges all WP branches for a feature, validates workspace-per-WP model

Workflow Example: Creating a Feature in 0.11.0

Let's walk through creating a feature using the new workflow:

Step 1: Planning (in main)

# Ensure you're in main
git checkout main

# Create specification
/spec-kitty.specify "Add user authentication"
→ kitty-specs/011-user-authentication/spec.md created in main
→ Committed to main

# Create plan
/spec-kitty.plan
→ kitty-specs/011-user-authentication/plan.md created in main
→ Committed to main

# Generate work packages
/spec-kitty.tasks
→ Creates WP01.md, WP02.md, WP03.md in main
→ Generates dependencies in frontmatter
→ Committed to main

# Check what was created
ls kitty-specs/011-user-authentication/tasks/
→ WP01-database-schema.md
→ WP02-api-endpoints.md
→ WP03-frontend-components.md

# Check worktrees (should be empty)
ls .worktrees/
→ (empty)

Step 2: Implementation (create worktrees)

# Implement WP01 (foundation)
spec-kitty implement WP01
→ Created .worktrees/011-user-authentication-WP01/
→ Branch: 011-user-authentication-WP01 (from main)

# Agent A works here
cd .worktrees/011-user-authentication-WP01/
# ... implement database schema ...
git add .
git commit -m "Implement database schema"

# Go back to main
cd /path/to/main/repo

# Implement WP02 (depends on WP01)
spec-kitty implement WP02 --base WP01
→ Created .worktrees/011-user-authentication-WP02/
→ Branch: 011-user-authentication-WP02 (from WP01)
→ Includes WP01's code

# Agent B works here (in parallel with Agent A!)
cd .worktrees/011-user-authentication-WP02/
# ... implement API endpoints ...

# Implement WP03 (independent)
spec-kitty implement WP03
→ Created .worktrees/011-user-authentication-WP03/
→ Branch: 011-user-authentication-WP03 (from main)

# Agent C works here (also in parallel!)
cd .worktrees/011-user-authentication-WP03/
# ... implement frontend components ...

Result: Three agents working simultaneously on different WPs!

Step 3: Review and Merge

# Review WP01
/spec-kitty.review WP01
→ Moves to for_review lane
→ Warns: "WP02 depends on WP01. If changes requested, WP02 needs rebase"

# After all WPs complete, merge feature
spec-kitty merge 011-user-authentication
→ Merges all WP branches to main
→ Optionally removes worktrees

Troubleshooting Upgrade Issues

Issue: "Cannot upgrade, legacy worktrees detected"

Error message:

❌ Cannot upgrade to 0.11.0
Legacy worktrees detected:
  - 008-unified-python-cli
  - 009-improved-documentation

Complete or delete these features before upgrading.

Solution: Go back to "Pre-Upgrade Checklist" → Step 3 and complete or delete each listed feature.

Issue: "Uncommitted changes in worktree"

When trying to complete a feature:

❌ Cannot merge feature 008-unified-python-cli
Uncommitted changes detected in .worktrees/008-unified-python-cli/

Solution:

cd .worktrees/008-unified-python-cli/
git status  # Check what's uncommitted
git add .
git commit -m "Commit remaining changes"
cd /path/to/main/repo
spec-kitty merge 008-unified-python-cli

Issue: "Feature artifacts in main but no worktree"

If you have kitty-specs/009-feature/ in main but no worktree:

Scenario 1: Feature was already merged

# Check git history
git log --all --grep="009-feature"

# If merged, clean up artifacts
rm -rf kitty-specs/009-feature
git add kitty-specs/
git commit -m "Clean up merged feature 009 artifacts"

Scenario 2: Feature was planned but never implemented

# Feature exists in main but was never started
# Safe to delete if you don't need it
rm -rf kitty-specs/009-feature
git add kitty-specs/
git commit -m "Remove unimplemented feature 009"

Issue: Upgrade broke my workflow

If you encounter issues after upgrading:

Rollback to 0.10.12:

pip install spec-kitty-cli==0.10.12
spec-kitty --version  # Should show 0.10.12

Note: Features planned in 0.11.0 format (artifacts in main) will need re-planning if you rollback to 0.10.12 (worktree model).

Report the issue: Please report bugs at: https://github.com/Priivacy-ai/spec-kitty/issues

Include:

  • Error message
  • Output of spec-kitty --version
  • Steps to reproduce

Benefits of the New Model

After upgrading, you'll benefit from:

  1. Parallel development: Multiple agents work on different WPs simultaneously
  2. Better isolation: Each WP has its own worktree and branch
  3. Explicit dependencies: Dependencies declared in frontmatter, validated automatically
  4. Cleaner main: Planning artifacts visible in main (no need to cd to worktree to see plan)
  5. Scalability: Features with 10+ WPs can have multiple agents working in parallel
