Phase 1: Analyze Current Schedule

Step 1a: Get Calendar Data

Receive schedule data from calendar-reviewer:

• Meetings list with times and durations
• Free time blocks with energy patterns
• All-day events
• Summary statistics

Step 1b: Calculate Schedule Metrics

**Meeting Load Analysis:**
- Total meetings: X
- Total meeting hours: X hrs
- Back-to-back meetings: X chains
- Longest meeting chain: X hours

**Time Availability:**
- Working hours: X hrs
- Scheduled (meetings): X hrs
- Free time: X hrs
- Available for focus: X hrs (after buffer/breaks)

**Energy Distribution:**
- Morning free time (8-11 AM): X hrs - 🔋 Deep Work
- Midday free time (11-2 PM): X hrs - 🤝 Collaboration
- Afternoon free time (2-5 PM): X hrs - 📋 Focus Time

---

Phase 2: Detect Bottlenecks

Overcommitment Detection

schedule_utilization = (meeting_hours + focus_hours) / working_hours

if utilization > 0.85: flag = "🔴 OVERCOMMITTED"
elif utilization > 0.75: flag = "⚠️ HEAVILY SCHEDULED"
else: flag = "✅ MANAGEABLE"

Back-to-Back Meeting Detection

for each meeting_chain:
    if chain.duration > 2 hours:
        bottleneck = {
            type: "back-to-back meetings",
            duration: chain.duration,
            impact: "No breaks, reduced focus, meeting fatigue",
            severity: "high" if duration > 3 else "medium"
        }

Insufficient Deep Work Time

deep_work_blocks = filter(free_blocks, time="8-11 AM", min_duration=90)

if total_deep_work_time < 2 hours:
    bottleneck = {
        type: "insufficient deep work",
        available: total_deep_work_time,
        needed: "2+ hours",
        impact: "Complex tasks won't fit",
        severity: "high"
    }

Schedule Fragmentation

if count(blocks_under_45_min) > count(blocks_over_45_min):
    bottleneck = {
        type: "fragmented schedule",
        issue: "Many small gaps, few large blocks",
        impact: "Can't do meaningful work between meetings",
        severity: "medium"
    }

Bottleneck Report

## 🔍 SCHEDULE ANALYSIS

**Overall Health:** ✅ MANAGEABLE (70% scheduled)

---

### 🚨 BOTTLENECKS DETECTED: X

**1. ⚠️ Back-to-Back Meetings (3 hours)**
- Time: 9:00 AM - 12:00 PM
- Impact: No breaks, meeting fatigue
- Recommendation: Add 15-min buffer or decline optional meeting

**2. 🔴 Insufficient Deep Work (1 hour)**
- Available: 1 hour morning focus
- Needed: 2+ hours for complex tasks
- Recommendation: Reschedule afternoon meeting or split task

---

### ✅ STRENGTHS
- Morning has 1 hr deep work (8-9 AM)
- Lunch break preserved (12-1 PM)
- No meetings after 4 PM

---

Phase 3: Smart Daily Timeboxing

Step 3a: Get Todos

Read todos from daily note or receive from orchestrator:

• "Today's Focus" (top 3)
• "URGENT" section
• "IMPORTANT" section

Step 3b: Estimate Durations

Use config-based estimates:

{
  "taskDurationEstimates": {
    "emailResponse": 15,
    "slackFollowup": 15,
    "codeReview": 45,
    "jiraBug": 90,
    "jiraFeature": 180
  }
}

Step 3c: Match Todos to Slots

Algorithm:

1. Sort todos by priority (urgent first)
2. Sort free blocks by quality:
   • Deep work (90+ min, morning) = highest
   • Focus (60+ min, afternoon) = medium
   • Small (30-60 min) = low
3. For each todo:
   • Find smallest block that fits (with buffer)
   • Match energy: complex → morning, simple → afternoon
   • Check for conflicts
4. Constraints:
   • Max 75% of free time
   • 10-min buffer between blocks
   • Leave some flexibility

Step 3d: Present Timeboxing Plan

## ⏰ DAILY TIMEBOXING PLAN

**Todos to Schedule:** X
**Available Time:** X hrs
**Proposed Schedule:** X hrs (75% utilization)

---

### 📋 PROPOSED TIME BLOCKS

| Time | Task | Duration | Priority | Fit |
|------|------|----------|----------|-----|
| 8:00-9:30 AM | DMS-2166 User Corrections | 90 min | 🔴 Urgent | ✅ Perfect |
| 9:45-10:15 AM | Respond to PM email | 30 min | 🔴 Urgent | ⚠️ Short block |
| 1:00-1:45 PM | Code review PR #721 | 45 min | 🟡 Important | ✅ Good |
| 3:00-4:30 PM | DMS-2350 Admin Dashboard | 90 min | 🟡 Important | ✅ Perfect |

**Not Scheduled:**
- DMS-2399 Mobile Integration (180 min needed, largest block: 90 min)
  → Suggestion: Schedule tomorrow or split into 2 sessions

---

**Create these focus blocks?**
- 'yes' - Create all X calendar events
- 'pick' - Select specific blocks
- 'no' - Skip (tasks still in daily note)

---

Phase 4: Create Focus Block Events

CRITICAL: Requires explicit user approval

Step 4a: Create Event

After user approves:

Bash: gws calendar +insert --summary "[Focus] DMS-2166 User Corrections" --start "2026-04-07T08:00:00-04:00" --end "2026-04-07T09:30:00-04:00"

For events needing more metadata (description, color):

Bash: gws calendar events insert --params '{"calendarId": "primary"}' --json '{"summary": "[Focus] DMS-2166 User Corrections", "start": {"dateTime": "2026-04-07T08:00:00", "timeZone": "America/Toronto"}, "end": {"dateTime": "2026-04-07T09:30:00", "timeZone": "America/Toronto"}, "description": "Priority: Urgent\nSource: Jira DMS-2166", "colorId": "9"}'

Step 4b: Verify Creation

Bash: gws calendar +agenda --today --format json

Confirm event appears in response.

Step 4c: Report Results

## ✅ FOCUS BLOCKS CREATED

| Time | Event | Status |
|------|-------|--------|
| 8:00-9:30 AM | [Focus] DMS-2166 User Corrections | ✅ Created |
| 9:45-10:15 AM | [Focus] PM email response | ✅ Created |
| 1:00-1:45 PM | [Focus] Code review PR #721 | ✅ Created |
| 3:00-4:30 PM | [Focus] DMS-2350 Admin Dashboard | ✅ Created |

**To remove:** Open calendar → Click event → Delete

Phase 5: Recurring Strategic Blocks

Step 5a: Check for Missing Blocks

Recurring block templates from config:

{
  "recurringBlocks": [
    {
      "name": "Security Audit",
      "frequency": "monthly",
      "dayOfMonth": 15,
      "duration": 120,
      "description": "Monthly security review",
      "color": "red"
    },
    {
      "name": "DevSecOps Review",
      "frequency": "quarterly",
      "duration": 180,
      "description": "Quarterly DevSecOps review"
    },
    {
      "name": "Process Improvement",
      "frequency": "monthly",
      "dayOfMonth": 1,
      "duration": 90
    },
    {
      "name": "Professional Development",
      "frequency": "weekly",
      "dayOfWeek": "Friday",
      "timeSlot": "15:00",
      "duration": 60
    }
  ]
}

Step 5b: Search for Existing

Bash: gws calendar events list --params '{"calendarId": "primary", "q": "[Strategic] Security Audit", "timeMin": "FIRST_OF_MONTH", "timeMax": "END_OF_NEXT_MONTH", "singleEvents": true}'

Step 5c: Report Missing Blocks

## 📅 RECURRING STRATEGIC BLOCKS

### ⚠️ MISSING THIS MONTH: X

1. **Security Audit** (120 min)
   - Due: January 15 (6 days away)
   - Status: ❌ NOT SCHEDULED
   - Recommendation: Schedule this week

2. **Process Improvement** (90 min)
   - Due: February 1 (23 days away)
   - Status: ❌ NOT SCHEDULED

### ✅ SCHEDULED

| Date | Block | Duration | Status |
|------|-------|----------|--------|
| Jan 10 | Professional Development | 60 min | ✅ 3-4 PM |

---

**Schedule missing blocks?**
- 'yes' - Schedule all with recommended times
- 'pick' - Select specific blocks
- 'custom' - Choose different times
- 'no' - Skip

Step 5d: Create Strategic Events

After approval:

For simple one-time events:

Bash: gws calendar +insert --summary "[Strategic] Security Audit" --start "2026-04-15T09:00:00-04:00" --end "2026-04-15T11:00:00-04:00"

For recurring events with full metadata:

Bash: gws calendar events insert --params '{"calendarId": "primary"}' --json '{"summary": "[Strategic] Security Audit", "start": {"dateTime": "2026-04-15T09:00:00", "timeZone": "America/Toronto"}, "end": {"dateTime": "2026-04-15T11:00:00", "timeZone": "America/Toronto"}, "description": "Monthly security review: dependencies, vulnerabilities, access audit", "recurrence": ["RRULE:FREQ=MONTHLY;BYMONTHDAY=15"], "colorId": "11"}'

---

Phase 6: Optimization Recommendations

## 💡 OPTIMIZATION RECOMMENDATIONS

**Priority Actions:**
1. 🔴 **Schedule Security Audit** - Missing this month
2. 🔴 **Decline 2 PM meeting** - Reduces overcommitment 85%→75%
3. 🟡 **Add buffer after standup** - Prevents meeting fatigue

**Strategic Actions:**
4. 🟡 **Block Friday 3-4 PM** for Professional Development
5. 🟢 **Create morning deep work protection** (Mon/Wed/Fri 8-10 AM)

---

### 📊 BEFORE vs AFTER

| Metric | Before | After |
|--------|--------|-------|
| Utilization | 85% | 70% ✅ |
| Deep work | 1 hr | 2.5 hrs ✅ |
| Back-to-back | 3 hrs | <2 hrs ✅ |
| Strategic blocks | 0/3 | 3/3 ✅ |

**Expected Impact:**
- 🎯 Focus time +150%
- ⚡ Reduced meeting fatigue
- 📈 Strategic work scheduled

---

Safety Rules

CRITICAL:

1. NEVER modify existing events - Only create new ones
2. REQUIRE explicit approval before creating ANY event
3. NEVER accept/decline meeting invitations
4. NEVER delete events
5. Use [Focus] or [Strategic] prefix for created events
6. Provide undo instructions for all creations

---

Error Handling

Event Creation Fails

• Report specific error
• Continue with other events
• Provide manual creation instructions
• NEVER retry without user approval

GWS CLI Fails

• Fall back to text-based timeboxing plan
• Suggest user creates events manually
• Suggest checking authentication: gws auth login
• Continue with recommendations

Bottleneck Detection Issues

• Provide basic schedule analysis
• Skip advanced recommendations
• Note: "Advanced analysis unavailable"
