Sync Acceptance Criteria Status

Sync Acceptance Criteria Status

Purpose: Manually trigger AC checkbox synchronization to ensure spec.md acceptance criteria accurately reflect task completion status.

Use When:

• AC checkboxes in spec.md are out of sync with completed tasks
• After manually completing tasks without running the hook
• To verify AC status before closing an increment
• To resolve conflicts between manual AC edits and task completion

---

How It Works

1. Detect Active Increment

   • Find increment in-progress
   • Check if spec.md and tasks.md exist

2. Parse Task Completion

   • Extract all tasks from tasks.md
   • Map AC-IDs to completion status
   • Calculate percentage complete per AC (# complete tasks / # total tasks)

3. Parse AC Definitions

   • Extract all ACs from spec.md
   • Track current checkbox state ([ ] or [x])
   • Map line numbers for atomic updates

4. Intelligent Sync Logic

   • 100% Complete: Update [ ] → [x]
   • < 100% Complete: Keep [ ] (partial work)
   • Conflict Detection: AC is [x] but tasks incomplete → WARN
   • Orphaned ACs: AC has no implementing tasks → WARN

5. Atomic File Update

   • Update spec.md only if changes needed
   • Preserve manual overrides (conflicts)
   • Log all changes to metadata.json

Usage

# Auto-detect and sync active increment
/​sw:sync-acs

# Sync specific increment
/​sw:sync-acs 0039

# Show what would change (dry run)
/​sw:sync-acs --dry-run

# Force sync (ignore conflicts)
/​sw:sync-acs --force

# Validate only (check for mismatches)
/​sw:sync-acs --validate

---

Implementation

The command uses ACStatusManager for sophisticated synchronization:

import { ACStatusManager } from '../​../​../​../​../​src/​core/​increment/​ac-status-manager';

const manager = new ACStatusManager(process.cwd());
const result = await manager.syncACStatus(incrementId);

// result.synced: true if sync was performed
// result.updated: string[] - AC-IDs updated to [x]
// result.conflicts: string[] - Conflicts detected
// result.warnings: string[] - Orphaned ACs, missing files
// result.changes: string[] - Human-readable diff

Step 1: Find Active Increment

# Auto-detect active increment
ACTIVE_INCREMENT=$(ls -t .specweave/​increments/ 2>/​dev/​null | grep -v "_backlog\|_archive" | head -1)

if [[ -z "$ACTIVE_INCREMENT" ]]; then
    echo "❌ No active increment found"
    exit 1
fi

echo "🔄 Syncing AC status for $ACTIVE_INCREMENT..."

Step 2: Call ACStatusManager

# Use the update-ac-status.js hook script (already integrated)
node plugins/​specweave/​lib/​hooks/​update-ac-status.js "$ACTIVE_INCREMENT"

Or invoke directly:

const result = await manager.syncACStatus(incrementId);

Step 3: Display Results

# Updated ACs
if [[ -n "${result.updated}" ]]; then
    echo "✅ Updated AC checkboxes:"
    for acId in "${result.updated[@]}"; do
        echo "   $acId → [x]"
    done
fi

# Conflicts
if [[ -n "${result.conflicts}" ]]; then
    echo "⚠️  Conflicts detected:"
    for conflict in "${result.conflicts[@]}"; do
        echo "   $conflict"
    done
fi

# Warnings
if [[ -n "${result.warnings}" ]]; then
    echo "⚠️  Warnings:"
    for warning in "${result.warnings[@]}"; do
        echo "   $warning"
    done
fi

Example Scenarios

Scenario 1: Normal Sync (100% Complete AC)

Before:

# spec.md
- [ ] AC-US1-01: User can login
- [ ] AC-US1-02: Session persists

# tasks.md
#### T-001: Implement login API
**AC**: AC-US1-01
**Status**: [x] (100% - Completed)

#### T-002: Add session storage
**AC**: AC-US1-01
**Status**: [x] (100% - Completed)

After:

# spec.md
- [x] AC-US1-01: User can login  ✓ UPDATED
- [ ] AC-US1-02: Session persists

Output:

🔄 Syncing AC status for increment 0039...

✅ Updated AC checkboxes:
   AC-US1-01 → [x]

📝 Changes:
   AC-US1-01: [ ] → [x] (2/​2 tasks complete - 100%)

---

Scenario 2: Partial Completion (No Update)

Before:

# spec.md
- [ ] AC-US1-02: Session persists

# tasks.md
#### T-003: Add Redis session store
**AC**: AC-US1-02
**Status**: [x] (100% - Completed)

#### T-004: Test session expiry
**AC**: AC-US1-02
**Status**: [ ] (0% - Not started)

After:

# spec.md
- [ ] AC-US1-02: Session persists  (NO CHANGE - 50% complete)

Output:

🔄 Syncing AC status for increment 0039...

ℹ️  No AC updates needed

📊 Completion Status:
   AC-US1-02: 1/​2 tasks complete (50%) - threshold not met

---

Scenario 3: Conflict Detection

Before:

# spec.md
- [x] AC-US1-03: Data validated (manually checked)

# tasks.md
#### T-005: Add validation rules
**AC**: AC-US1-03
**Status**: [x] (100% - Completed)

#### T-006: Add error handling
**AC**: AC-US1-03
**Status**: [ ] (0% - Not started)

After:

# spec.md
- [x] AC-US1-03: Data validated (PRESERVED - conflict detected)

Output:

🔄 Syncing AC status for increment 0039...

⚠️  Conflicts detected:
   AC-US1-03: Marked [x] but only 1/​2 tasks complete (50%)
   → Manual override preserved (no change made)

💡 Tip: Review tasks for AC-US1-03 or uncheck manually if premature

---

Scenario 4: Orphaned AC Warning

Before:

# spec.md
- [ ] AC-US1-04: Performance optimized
- [ ] AC-US1-05: Security hardened

# tasks.md
#### T-007: Implement caching
**AC**: AC-US1-04
**Status**: [x] (100% - Completed)

(No tasks reference AC-US1-05)

Output:

🔄 Syncing AC status for increment 0039...

✅ Updated AC checkboxes:
   AC-US1-04 → [x]

⚠️  Warnings:
   AC-US1-05: No implementing tasks found (orphaned AC)
   → Add tasks or remove AC from spec.md

---

Integration with Hooks

Automatic Sync (Post-Task-Completion Hook)

The hook automatically calls ACStatusManager.syncACStatus() after every task completion:

# plugins/​specweave/​hooks/​post-task-completion.sh (lines 232-269)
if [ -n "$CURRENT_INCREMENT" ]; then
    node plugins/​specweave/​lib/​hooks/​update-ac-status.js "$CURRENT_INCREMENT"
fi

Disable automatic sync:

export SKIP_AC_SYNC=true
# Now hooks won't sync ACs (useful for batch work)

---

Integration with Other Commands

/​sw:validate

# Validate ACs before closing increment
/​sw:sync-acs --validate
# Warns if ACs out of sync

/​sw:done

# Auto-sync ACs before closing
/​sw:sync-acs
# Then proceed with increment closure

/​sw:progress

# Show AC completion alongside task progress
/​sw:sync-acs --status
# Display: 8/​10 ACs complete (80%)

---

Success Criteria

• ✅ Syncs AC checkboxes based on task completion (100% threshold)
• ✅ Detects and preserves manual overrides (conflicts)
• ✅ Warns about orphaned ACs (no implementing tasks)
• ✅ Shows clear diff of changes before/​after
• ✅ Atomic file writes (no corruption risk)
• ✅ Integrates with post-task-completion hook
• ✅ Supports dry-run mode
• ✅ Logs all changes to metadata.json
