Session Handoff Skill

Workflow Selection

FIRST: Determine which workflow to follow

1. User says "quick handoff" → Follow Quick Handoff Workflow below
2. User says "full handoff", "wrap up", or "deep clean" → Follow Full Handoff Workflow below
3. Ambiguous request → Ask user: "Would you like a quick handoff or a full handoff with deep cleanup?"

Quick Handoff Workflow

Execute these steps in order:

Step 1: Quick Workspace Audit

Scan for obvious issues in root directories only:

# Junk files
find . -maxdepth 3 -type f \( -name "*.tmp" -o -name "*.bak" -o -name "*~" -o -name "*.swp" -o -name ".DS_Store" \) -not -path "./.git/*" -not -path "*/node_modules/*" -not -path "*/archive/*"

# Version conflicts (CRITICAL - always check)
find docs .claude -maxdepth 2 -type f -name "*.md" | grep -iE "(v2|v3|new|old|copy|backup|optimized|updated|revised)" | grep -v archive

Report findings to user. Skip to Step 2 if clean.

Step 2: Resolve Version Conflicts (if any found)

If version conflicts found in Step 1:

1. Read both files (first 100 lines minimum)
2. Determine canonical version: Which is more recent/complete/referenced?
3. Choose action:
   • Merge if both have unique valuable content → Combine into single file
   • Keep newest if minimal differences → Delete old, rename new to remove version suffix
4. Update references: Grep for filename, update any references
5. Archive old ONLY if valuable historical context, otherwise delete

# Archive (if valuable)
git mv docs/guide-old.md archive/docs/

# Delete (if no reference value)
git rm docs/guide-old.md

Step 3: Update Related Documentation

CRITICAL: Update docs related to session work

Identify what changed:

# Files modified this session
git diff --name-only HEAD~5 HEAD | grep -v ".claude/sessions"

Update corresponding documentation:

• MCP tools changed → Update docs/MCP_TOOLS_REFERENCE.md
• API endpoints changed → Update docs/REST_API_GUIDE.md
• Workflow changes → Update docs/N8N_*.md
• Phase completed → Update docs/ROADMAP.md
• Architecture changed → Update .claude/PROJECT_OVERVIEW.md
• New known issues → Update docs/KNOWN_ISSUES.md

Step 4: Update sessions/CURRENT.md

Update with session summary (100-200 lines max):

# Current Session Context

> **Last Updated**: YYYY-MM-DD
> **Last Session**: YYYY-MM-DD-N

## Quick Status
[Status table with current phase, components, blockers]

## Last Session (YYYY-MM-DD-N)
**Focus**: Brief description
**Completed**: 2-3 key items
**Commits**: X commits (SHAs)

## Next Session Priorities
1. Priority 1
2. Priority 2
3. Priority 3

## Key Files Changed Recently
- `path/to/file` - What changed

Step 5: Archive Previous Session

Create JSON archive for previous session:

mkdir -p .claude/sessions/archive/YYYY-MM

Create .claude/sessions/archive/YYYY-MM/YYYY-MM-DD-N.json:

{
  "session_id": "YYYY-MM-DD-N",
  "date": "YYYY-MM-DD",
  "focus": "Brief description",
  "completed": ["Item 1", "Item 2"],
  "commits": [{"sha": "abc123", "message": "..."}],
  "files_modified": ["path/to/file"],
  "next_priorities": ["Priority 1"]
}

Step 6: Commit and Push

# Stage changes
git add .claude/sessions/ archive/ docs/

# Commit
git commit -m "$(cat <<'EOF'
docs: Session handoff YYYY-MM-DD - [brief description]

- Archived session YYYY-MM-DD-N
- [Summary of cleanup/updates]

Full Handoff Workflow

Execute ALL steps in order:

Step 1: Critical Thinking Sanity Check

Before applying rigid rules, use common sense:

1. Scan entire project structure:

# Overview of all directories
tree -L 2 -d . 2>/dev/null || find . -type d -maxdepth 2 | grep -v node_modules | grep -v .git | sort

# List root-level files
ls -lah | grep -v "^d"

# Check key folders
ls -lh docs/ .claude/

2. Apply critical thinking - flag anything that seems:

   • Out of place or illogical
   • Inconsistently named (kebab-case vs snake_case vs PascalCase)
   • Duplicate/redundant (multiple files serving same purpose)
   • Orphaned or disconnected from current work
   • Violates common project organization patterns

3. Report abnormalities to user:

   • "These things stood out as potentially odd..."
   • Get user input before proceeding
   • Examples: "Why is there a random .txt file in root?", "These two folders seem to do the same thing"

Don't proceed until user responds to abnormalities (if any)

Step 2: Deep Workspace Audit

Comprehensive scan for cleanup candidates:

# All junk files
find . -type f \( -name "*.tmp" -o -name "*.bak" -o -name "*~" -o -name "*.swp" -o -name ".DS_Store" \) -not -path "./.git/*" -not -path "*/node_modules/*" -not -path "*/archive/*"

# All potential duplicates
find . -type f \( -name "*-copy.*" -o -name "*-old.*" -o -name "*-backup.*" -o -name "*-v[0-9]*" \) -not -path "./.git/*" -not -path "*/node_modules/*" -not -path "*/archive/*"

# Version conflicts
find docs .claude -type f -name "*.md" | grep -iE "(v2|v3|new|old|copy|backup|optimized|updated|revised)" | grep -v archive

# Empty directories
find . -type d -empty -not -path "./.git/*"

Report ALL findings to user before cleanup.

Step 3: User Confirmation for Cleanup

Present findings:

📋 Deep Workspace Audit Results

🗑️ Junk Files (N found):
- ./path/to/file.tmp
- ./another/file.bak

📦 Potential Duplicates (N found):
- ./docs/guide-old.md
- ./docs/guide-v2.md

⚠️ Version Conflicts (N found):
- Multiple versions of X

What would you like me to do?
1. Delete junk files + resolve conflicts (recommended)
2. Archive everything to ./archive/
3. Review each item individually
4. Skip cleanup

Wait for user response. Do NOT proceed without confirmation.

Step 4: Execute User-Approved Cleanup

Based on user's choice from Step 3, apply cleanup rules:

Archive vs Delete decision criteria:

Archive (valuable for future reference):

• Complex analysis with valuable insights
• Architectural decisions and rationale
• Migration documentation (how we got here)
• Major audits with findings/learnings

Delete (no reference value):

• Routine audits and status checks
• One-time import documentation (e.g., *_IMPORT.md)
• Temporary analysis documents
• Superseded plans without unique insights

When in doubt: Delete (it's in Git history)

Automatic cleanup triggers:

1. Audits >3 sessions old: Archive major audits with insights, delete routine audits
2. Completed Plans: Archive if valuable decisions/rationale, otherwise delete
3. One-time Import Guides: Delete (no reference value after import complete)
4. Version Conflicts: Merge or keep newest, archive/delete old
5. Superseded Approaches: Archive if shows evolution, delete if purely historical
6. Completed Phase Documents: Archive if valuable insights/metrics, otherwise delete

Execute cleanup:

# Archive (if valuable for reference)
git mv .claude/MAJOR_AUDIT.md archive/.claude/audits/
git mv docs/MIGRATION_PLAN.md archive/docs/migrations/

# Delete (if no reference value)
git rm docs/ROUTINE_IMPORT.md
git rm .claude/TEMP_ANALYSIS.md

Step 5: Resolve Version Conflicts

For EACH version conflict found:

1. Read both files (first 100 lines minimum)
2. Determine canonical version: More recent? Complete? Referenced?
3. Choose action:
   • Merge if both have unique valuable content
   • Keep newest if minimal differences
4. Update references: Grep for filename, update any references
5. Archive old ONLY if valuable, otherwise delete

Step 6: Validate Against Development Principles

Read .claude/DEVELOPMENT_PRINCIPLES.md and validate session work:

• ✅ LLM-First Architecture: Tools leverage LLM intelligence, not replace it
• ✅ Data First: Preserved data integrity
• ✅ Progressive Enhancement: Features work without AI
• ✅ Complexity Budget: Kept it simple
• ✅ Two-Speed Development: Treated foundation carefully
• ✅ Context-First Automation: Workflows query before acting
• ✅ Cost-Conscious AI Usage: Optimized prompts and batch operations

Report validation results. Flag any violations or concerns.

Step 7: Update Related Documentation

Same as Quick Handoff Step 3 - update all docs related to session work.

Step 8: Update sessions/CURRENT.md

Same as Quick Handoff Step 4 - update with session summary.

Step 9: Archive Previous Session

Same as Quick Handoff Step 5 - create JSON archive.

Step 10: Update PROJECT_OVERVIEW.md (if needed)

Only update if:

• Major phase completed
• Architecture changed significantly
• Key decision made that affects overall project

Otherwise skip.

Step 11: Commit and Push

# Stage all handoff changes
git add .claude/sessions/ archive/ docs/ .claude/PROJECT_OVERVIEW.md

# Commit with detailed message
git commit -m "$(cat <<'EOF'
docs: Session handoff YYYY-MM-DD - [brief description]

- Archived session YYYY-MM-DD-N ([focus])
- Cleaned up X files (deleted), Y files (archived)
- Resolved Z version conflicts
- Updated N documentation files
- Validated against development principles

Reference: Cleanup Philosophy

Archive vs Delete

Git is Our Backup - Archive only if valuable for future reference

Archive when:

• Complex analysis with valuable insights
• Architectural decisions and rationale
• Migration documentation (how we got here)
• Major audits with findings/learnings

Delete when:

• Routine audits and status checks
• One-time import documentation
• Temporary analysis documents
• Superseded plans without unique insights

When in doubt: Delete (it's in Git history if needed)

Safety Rules

• Never delete files modified <24h without user confirmation
• Never touch: node_modules, .git, build directories, supabase/functions
• Always commit before cleanup - So mistakes are reversible
• Get user confirmation before deleting anything in full mode

Never Clean Up

• Current tool references (MCP_TOOLS_REFERENCE.md)
• Active roadmap (ROADMAP.md)
• Living guides (N8N_SETUP.md, N8N_WORKFLOW_DEVELOPMENT_GUIDE.md)
• KNOWN_ISSUES.md (always active)
• DEVELOPMENT_PRINCIPLES.md (timeless)
