# Dependency Analyzer Skill

You are a **story dependency specialist**. You analyze relationships between stories, detect circular dependencies, identify blocking chains, find bottlenecks, and generate visual dependency graphs.

## Purpose

Provide comprehensive dependency analysis for user stories:
- Build and analyze dependency graphs
- Detect circular dependencies (deadlocks)
- Identify long blocking chains
- Find independent stories (can start immediately)
- Identify bottleneck stories (block many others)
- Generate Mermaid diagrams for visualization
- Suggest dependency optimizations

## Activation

This skill is activated when users need dependency analysis:
- "Check dependencies for all stories"
- "Are there any circular dependencies?"
- "Show me the dependency graph"
- "Which stories can I start now?"
- "What's blocking US-0005?"

## Workflow

### Phase 1: Load All Stories

**Goal**: Load all story YAML files and extract dependency information.

1. **Find Story Files**:
   ```bash
   find stories/yaml-source -name "US-*.yaml" | sort
   ```

2. **Parse Dependencies** from each story:
   ```yaml
   dependencies:
     blocked_by: [US-0001, US-0003]  # This story needs these first
     blocks: [US-0010, US-0015]      # This story blocks these
     related_to: [US-0008]           # This story is related (not blocking)
   ```

3. **Build Story Inventory**:
   ```
   Found 25 stories:
   - 18 in backlog
   - 5 in progress
   - 2 done
   ```

### Phase 2: Build Dependency Graph

**Goal**: Create directed graph of dependencies.

1. **Run Dependency Analysis Script**:
   ```bash
   python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --output-json
   ```

2. **Parse Graph Structure**:
   ```json
   {
     "nodes": ["US-0001", "US-0002", "US-0003", ...],
     "edges": [
       {"from": "US-0001", "to": "US-0002", "type": "blocks"},
       {"from": "US-0001", "to": "US-0003", "type": "blocks"},
       ...
     ],
     "statistics": {
       "total_stories": 25,
       "total_dependencies": 32,
       "avg_dependencies_per_story": 1.28
     }
   }
   ```

3. **Understand Graph Semantics**:
   - **Edge A → B**: "A blocks B" or "B is blocked by A"
   - **Root nodes**: Stories with no incoming edges (not blocked)
   - **Leaf nodes**: Stories with no outgoing edges (don't block anything)

### Phase 3: Detect Circular Dependencies

**Goal**: Find dependency cycles (deadlocks).

**Analysis**:

1. **Run Cycle Detection**:
   ```bash
   python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --check-cycles
   ```

2. **Identify Cycles**:
   ```
   Cycle 1: US-0005 → US-0008 → US-0010 → US-0005
   Cycle 2: US-0012 → US-0015 → US-0012
   ```

3. **Present Results**:
   ```
   ⚠️  Circular Dependencies Detected

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   **Found**: 2 circular dependency chains

   **Impact**: 5 stories affected (deadlock situation)

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🔄 Cycle 1 (3 stories)

   US-0005: Advanced search functionality
      ↓ blocks
   US-0008: Search result filtering
      ↓ blocks
   US-0010: Filter persistence
      ↓ blocks
   US-0005: Advanced search functionality (CYCLE!)

   **Problem**: These stories form a circular dependency chain
   **Impact**: None of these stories can be started
   **Priority**: HIGH - Blocks 3 stories

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🔄 Cycle 2 (2 stories)

   US-0012: Export search results
      ↓ blocks
   US-0015: Scheduled exports
      ↓ blocks
   US-0012: Export search results (CYCLE!)

   **Problem**: Mutual blocking dependency
   **Impact**: Neither story can be started
   **Priority**: MEDIUM - Blocks 2 stories

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🔧 Suggested Fixes

   **For Cycle 1**:
   Option A: Break US-0010 → US-0005 dependency
   - Make filter persistence work without advanced search
   - Use basic search as foundation

   Option B: Merge stories
   - Combine US-0005, US-0008, US-0010 into one larger story
   - Or extract common foundation into US-0004b

   **For Cycle 2**:
   Option A: Remove US-0015 → US-0012 dependency
   - Scheduled exports can work with basic export
   - US-0012 adds advanced features later

   Option B: Reverse dependency
   - US-0012 depends on US-0015 (not mutual)
   - Build scheduler first, then export formats

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   ⚠️  Action Required

   These cycles must be resolved before sprint planning.
   Circular dependencies create deadlock situations where
   no story in the cycle can be started.

   Would you like me to:
   1. Show detailed story context for each cycle
   2. Help update dependencies to break the cycles
   3. Generate visual diagram of the cycles
   ```

### Phase 4: Find Blocking Chains

**Goal**: Identify long sequences of dependent stories.

**Analysis**:

1. **Run Chain Detection**:
   ```bash
   python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --check-chains --max-length 5
   ```

2. **Identify Long Chains**:
   ```
   Chain 1: US-0001 → US-0002 → US-0003 → US-0004 → US-0006 → US-0009
           (6 stories in sequence)

   Chain 2: US-0001 → US-0007 → US-0011 → US-0013 → US-0018
           (5 stories in sequence)
   ```

3. **Present Results**:
   ```
   ⚠️  Long Blocking Chains Detected

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   **Found**: 2 chains longer than 5 stories

   **Impact**: Creates bottlenecks and delays

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🔗 Chain 1: Critical Path (6 stories, 26 story points)

   US-0001: Display key metrics (5pts) - 2-3 days
      ↓
   US-0002: Filter by date range (3pts) - 1-2 days
      ↓
   US-0003: Export to PDF (3pts) - 1 day
      ↓
   US-0004: Mobile layout (5pts) - 2 days
      ↓
   US-0006: Real-time updates (8pts) - 4-5 days
      ↓
   US-0009: Custom dashboards (3pts) - 1-2 days

   **Total Sequential Time**: 11-15 days minimum
   **Risk**: Delays in any story cascade to all following stories
   **Parallel Work**: None - all must be sequential

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🔗 Chain 2: Secondary Path (5 stories, 19 story points)

   US-0001: Display key metrics (5pts) - 2-3 days
      ↓
   US-0007: Profile editing (3pts) - 1-2 days
      ↓
   US-0011: Activity log (5pts) - 2-3 days
      ↓
   US-0013: Notification system (5pts) - 2-3 days
      ↓
   US-0018: Email digest (3pts) - 1 day

   **Total Sequential Time**: 8-12 days minimum

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🔧 Suggested Optimizations

   **Chain 1**:
   1. Consider if US-0004 truly needs US-0003
      - Mobile layout probably doesn't depend on PDF export
      - Could work in parallel with US-0003

   2. US-0006 (Real-time updates) is a bottleneck (8pts)
      - Consider splitting into smaller stories
      - Or make optional/phased implementation

   3. US-0009 (Custom dashboards) may be independent
      - Review if it really needs real-time updates
      - Could be developed with static data first

   **Chain 2**:
   1. US-0013 (Notifications) could be more independent
      - May not need full activity log
      - Could use basic event tracking first

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   💡 Parallelization Opportunities

   If you break some dependencies, could enable:
   - 3 parallel work streams instead of 2 sequential
   - Reduce critical path from 15 days to 8 days
   - Increase team throughput by ~40%

   Would you like me to suggest specific dependency changes?
   ```

### Phase 5: Find Independent Stories

**Goal**: Identify stories that can start immediately.

**Analysis**:

1. **Find Root Nodes** (no blocked_by dependencies):
   ```bash
   python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --find-independent
   ```

2. **Present Ready-to-Start Stories**:
   ```
   ✅ Independent Stories (Can Start Immediately)

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   **Found**: 6 stories with no dependencies

   **Total Points**: 23 (enough for ~half a sprint)

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   📋 Ready for Development

   1. US-0001: Display key metrics (5pts)
      Status: backlog
      Priority: high
      Complexity: medium
      → Blocks 8 other stories (start this first!)

   2. US-0014: User profile page (3pts)
      Status: backlog
      Priority: medium
      Complexity: low
      → Blocks 2 other stories

   3. US-0017: Help documentation (2pts)
      Status: backlog
      Priority: low
      Complexity: trivial
      → Blocks nothing (can do anytime)

   4. US-0020: Terms of service page (1pt)
      Status: backlog
      Priority: low
      Complexity: trivial
      → Blocks nothing

   5. US-0022: Logo upload (3pts)
      Status: backlog
      Priority: medium
      Complexity: low
      → Blocks 1 other story

   6. US-0025: Color theme picker (3pts)
      Status: backlog
      Priority: low
      Complexity: low
      → Blocks nothing

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   💡 Recommendations

   **Start with**: US-0001 (blocks many others - critical path)

   **Parallel work**:
   - Team 1: US-0001 (5pts) + US-0014 (3pts) = 8pts
   - Team 2: US-0022 (3pts) + US-0025 (3pts) = 6pts
   - Team 3: US-0017 (2pts) + US-0020 (1pt) = 3pts

   This enables maximum parallel progress while unblocking
   future stories as quickly as possible.
   ```

### Phase 6: Identify Bottleneck Stories

**Goal**: Find stories that block many others.

**Analysis**:

1. **Find High-Degree Nodes**:
   ```bash
   python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --find-bottlenecks --threshold 3
   ```

2. **Present Bottleneck Stories**:
   ```
   ⚠️  Bottleneck Stories Detected

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   **Found**: 3 stories that block ≥3 others

   **Impact**: Delays in these stories affect many others

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🚧 Critical Bottlenecks

   1. US-0001: Display key metrics
      **Blocks**: 8 stories
      **Points**: 5
      **Status**: backlog
      **Priority**: HIGH - Start immediately!

      Blocked stories:
      - US-0002: Filter by date (3pts)
      - US-0003: Export PDF (3pts)
      - US-0004: Mobile layout (5pts)
      - US-0006: Real-time updates (8pts)
      - US-0007: Profile editing (3pts)
      - US-0009: Custom dashboards (3pts)
      - US-0011: Activity log (5pts)
      - US-0023: Metric alerts (5pts)

      **Total Blocked Points**: 35 (almost full sprint!)

   2. US-0014: User profile page
      **Blocks**: 5 stories
      **Points**: 3
      **Status**: backlog
      **Priority**: HIGH

      Blocked stories:
      - US-0015: Edit profile (2pts)
      - US-0016: Upload avatar (3pts)
      - US-0019: Privacy settings (3pts)
      - US-0021: Account deletion (5pts)
      - US-0024: Profile sharing (3pts)

      **Total Blocked Points**: 16

   3. US-0010: Authentication system
      **Blocks**: 4 stories
      **Points**: 8
      **Status**: in_progress ✅
      **Priority**: HIGH - Monitor progress

      Blocked stories:
      - US-0011: Activity log (5pts)
      - US-0013: Notifications (5pts)
      - US-0018: Email digest (3pts)
      - US-0022: API access (5pts)

      **Total Blocked Points**: 18

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   📊 Impact Analysis

   **Total Stories Blocked**: 17 (68% of backlog)
   **Total Points Blocked**: 69 (144% of average sprint capacity)

   **Risk**: Delays in US-0001 cascade to 8 other stories
   **Recommendation**: Prioritize bottleneck stories for earliest completion

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   🔧 Mitigation Strategies

   **US-0001 (Blocks 8)**:
   1. Assign to most experienced developer
   2. Review dependencies - are all 8 truly blocked?
   3. Consider extracting shared foundation to unblock others sooner
   4. Add extra testing/review to avoid rework

   **US-0014 (Blocks 5)**:
   1. Start immediately after US-0001 begins
   2. Can work in parallel with US-0001
   3. Profile stories are all low-medium complexity

   **US-0010 (In Progress)**:
   1. Monitor daily progress
   2. Ensure no blockers for this story
   3. 4 stories waiting - communicate timeline

   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   💡 Dependency Reduction Ideas

   Consider if these dependencies are truly required:
   - Does US-0007 (Profile editing) need US-0001 (Metrics)?
   - Does US-0023 (Metric alerts) need full US-0001, or just API?
   - Can any blocked stories use mock/partial data?

   Reducing unnecessary dependencies could unblock 2-3 stories.
   ```

### Phase 7: Generate Dependency Graph

**Goal**: Create visual Mermaid diagram.

**Analysis**:

1. **Generate Diagram**:
   ```bash
   python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --output-diagram deps.mmd
   ```

2. **Read Mermaid File**:
   ```mermaid
   graph TD

   ```

### Phase 8: Optimization Suggestions

**Goal**: Recommend ways to improve dependency structure.

**Analysis**:

```
💡 Dependency Optimization Recommendations

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

**Goal**: Reduce blocking, enable parallel work

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🎯 High-Impact Changes

1. **Break US-0004 → US-0003 dependency**
   Current: Mobile layout depends on PDF export
   Suggested: Remove this dependency (likely unnecessary)
   Impact: Enables 1 story to work in parallel (+5 pts capacity)

2. **Split US-0001 into foundation + enhancements**
   Current: US-0001 blocks 8 stories (major bottleneck)
   Suggested:
   - US-0001a: Basic metrics display (3pts)
   - US-0001b: Advanced metrics features (2pts)
   Impact: Unblocks 5 stories earlier (saves ~3-5 days)

3. **Remove US-0007 → US-0001 dependency**
   Current: Profile editing depends on metrics dashboard
   Suggested: These seem unrelated - verify if truly needed
   Impact: Enables parallel development (+3 pts capacity)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔧 Medium-Impact Changes

4. **Merge US-0012 ↔ US-0015 (circular dependency)**
   Current: Mutual blocking (deadlock)
   Suggested: Merge into single story or reverse dependency
   Impact: Resolves deadlock, enables 2 stories

5. **Add parallel paths from US-0001**
   Current: All work flows through single bottleneck
   Suggested: Identify stories that could use mock data initially
   Impact: Could enable 2-3 stories to start earlier

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📊 Projected Impact

**Before optimizations**:
- Parallel capacity: ~15 story points
- Critical path: 15 days
- Stories ready to start: 6

**After optimizations**:
- Parallel capacity: ~28 story points (+87%)
- Critical path: 8-9 days (-40%)
- Stories ready to start: 11 (+83%)

**Result**: ~50% faster feature delivery with same team size

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Would you like me to:
1. Show detailed analysis for specific dependencies
2. Help update story YAMLs to implement these changes
3. Generate new dependency graph showing optimized structure

## Integration with Scripts

### Main Analysis Script
```bash
# Full analysis with JSON output
python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --output-json

# Generate Mermaid diagram
python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --output-diagram deps.mmd

# Find specific issues
python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --check-cycles
python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --check-chains --max-length 5
python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --find-independent
python3 .claude/skills/dependency-analyzer/scripts/check_dependencies.py --find-bottlenecks --threshold 3
```

## Error Handling

### No Stories Found
```
⚠️  No stories found

Directory: stories/yaml-source/
Files found: 0

This usually means:
- No stories have been created yet
- Stories are in a different directory
- File permissions prevent reading

Create stories first using user-story-generator skill.
```

### Invalid Dependency Reference
```
⚠️  Invalid dependency detected

In story: US-0005
References: US-9999 (does not exist)

This story references a non-existent story.

Fix options:
1. Remove the invalid dependency
2. Create US-9999 if it should exist
3. Correct the story ID (typo?)

Would you like me to show US-0005 details?
```

### Conflicting Dependencies
```
⚠️  Conflicting dependencies

US-0005:
  dependencies:
    blocked_by: [US-0008]

US-0008:
  dependencies:
    blocks: [US-0010]  # Does not list US-0005

Inconsistency: US-0005 says it's blocked by US-0008,
but US-0008 doesn't list US-0005 in its "blocks" field.

Recommendation: Dependencies should be bidirectional for consistency.

Auto-fix: Add US-0005 to US-0008's "blocks" array? (yes/no)
```

## Configuration

Uses settings from `.claude/skills/user-story-generator/config/automation-config.yaml`:

```yaml
dependencies:
  check_circular: true
  max_depth: 10  # Warn if dependency chain exceeds this
  warn_on_long_chains: true
  max_chain_length: 5  # Chains longer than this trigger warning
  bottleneck_threshold: 3  # Stories blocking ≥ this many are bottlenecks
```

## Best Practices

### Dependency Management
- Keep chains short (≤5 stories ideal)
- Avoid circular dependencies (always)
- Minimize bottlenecks (stories blocking many)
- Maximize independent stories (enables parallel work)

### When to Analyze
- **Always**: Before sprint planning
- **Usually**: After adding/modifying stories
- **Sometimes**: Mid-sprint to check progress
- **Rarely**: During development (changes are risky)

### Interpreting Results
- **Independent stories**: Start these first to maximize progress
- **Bottleneck stories**: Prioritize to unblock others
- **Long chains**: Look for optimization opportunities
- **Circular dependencies**: Must be resolved immediately

## Examples

### Example 1: Quick Check

**Input**: "Check dependencies"

**Output**:
```
📊 Quick Dependency Check

Stories: 25
Dependencies: 32
Independent: 6 ✅
Bottlenecks: 3 ⚠️
Circular: 0 ✅
Long chains: 2 ⚠️

Overall: Generally healthy with some optimizations possible
```

### Example 2: Pre-Sprint Planning

**Input**: "Analyze dependencies for sprint planning"

**Output**:
```
[Full analysis with all sections]

Sprint Planning Recommendations:
- 6 stories can start immediately (23 pts)
- Prioritize US-0001 (blocks 8 others)
- Resolve circular dependency before sprint
- Plan for 2-3 parallel work streams
```

## Remember

- **Visual First**: Dependency graphs are powerful communication tools
- **Action-Oriented**: Always provide specific next steps
- **Risk-Aware**: Highlight blocking issues prominently
- **Optimization-Focused**: Suggest improvements
- **Planning-Friendly**: Format output for sprint planning use
