## When to Use This Skill

Use this skill when:
- Planning new features or milestones
- Tracking development progress
- Viewing project roadmap
- Linking sessions to milestones
- Checking what's in progress or planned
- Answering "what should I work on next?"
- Generating progress reports

## Available Tools (MCP + CLI)

### MCP Tools (Programmatic Access)

**Query Tools:**
- `mcp__chronicle__get_milestones(status, milestone_type, limit)` - List milestones
- `mcp__chronicle__get_milestone(milestone_id)` - Get milestone details
- `mcp__chronicle__get_next_steps(completed, milestone_id, limit)` - List next steps
- `mcp__chronicle__get_roadmap(days)` - View project roadmap

**Update Tools:**
- `mcp__chronicle__update_milestone_status(milestone_id, new_status)` - Update status
- `mcp__chronicle__complete_next_step(step_id)` - Mark step complete

### CLI Commands (Portable)

**See "CLI Commands Reference" section below for full list.**

Key commands:
- `chronicle milestones` - List milestones
- `chronicle roadmap` - View roadmap
- `chronicle next-steps` - List next steps
- `chronicle milestone-complete <id>` - Mark complete

## Workflow: Planning a New Feature

When user wants to add a new feature:

1. **Check existing roadmap** to avoid duplicates:
   ```python
   roadmap = mcp__chronicle__get_roadmap(days=30)
   # Review planned milestones
   ```

2. **Create milestone** via CLI (user runs this):
   ```bash
   chronicle milestone "Feature name" \
     --description "What it does" \
     --type feature \
     --priority 1 \
     --tags "phase-5,api,backend"
   ```

3. **Break down into next steps**:
   ```bash
   chronicle next-step "Design API endpoints" --priority 1 --effort medium --milestone <ID>
   chronicle next-step "Write tests" --priority 2 --effort small --milestone <ID>
   chronicle next-step "Document in README" --priority 3 --effort small --milestone <ID>
   ```

4. **Update status when starting work**:
   ```python
   mcp__chronicle__update_milestone_status(milestone_id=1, new_status="in_progress")
   ```

## Workflow: Session Linking

When completing a development session:

1. **Get session ID** from recent sessions:
   ```python
   sessions = mcp__chronicle__get_sessions(limit=5)
   latest_session_id = sessions[0]['id']
   ```

2. **Find active milestone**:
   ```python
   milestones = mcp__chronicle__get_milestones(status="in_progress")
   active_milestone_id = milestones[0]['id']
   ```

3. **Link them** (user runs this):
   ```bash
   chronicle link-session <session_id> --milestone <milestone_id>
   ```

4. **Complete next steps** as work progresses:
   ```python
   mcp__chronicle__complete_next_step(step_id=1)
   ```

## Workflow: Generating Progress Reports

When user asks "what did I accomplish this week?":

1. **Get roadmap**:
   ```python
   roadmap = mcp__chronicle__get_roadmap(days=7)
   ```

2. **Extract info**:
   - `roadmap['recently_completed']` - Milestones completed in last 7 days
   - `roadmap['in_progress']` - Current active work
   - `roadmap['summary']` - Statistics

3. **Get linked sessions** for each completed milestone:
   ```python
   for milestone in roadmap['recently_completed']:
       milestone_details = mcp__chronicle__get_milestone(milestone['id'])
       sessions = milestone_details['linked_sessions']
       # Summarize work done
   ```

4. **Format report** showing:
   - Completed milestones with linked sessions
   - Git commits from those sessions
   - Time spent (from session durations)
   - Key files modified

## Workflow: Viewing Roadmap

When user asks "what's next?" or "show me the roadmap":

```python
# Get full roadmap
roadmap = mcp__chronicle__get_roadmap(days=7)

# Present in organized format:
print("🚧 IN PROGRESS:")
for m in roadmap['in_progress']:
    print(f"  - {m['title']} ({len(m['related_sessions'])} sessions)")

print("\n📋 PLANNED (High Priority):")
for m in roadmap['planned_high_priority']:
    print(f"  - [P{m['priority']}] {m['title']}")

print("\n🔜 NEXT STEPS:")
for step in roadmap['pending_next_steps']:
    effort = f" [{step['estimated_effort']}]" if step['estimated_effort'] else ""
    print(f"  - [P{step['priority']}] {step['description']}{effort}")

print("\n✅ RECENTLY COMPLETED:")
for m in roadmap['recently_completed']:
    print(f"  - {m['title']} ({m['completed_at']})")
```

## Workflow: Completing a Milestone

When all work for a milestone is done:

1. **Verify all next steps completed**:
   ```python
   steps = mcp__chronicle__get_next_steps(milestone_id=<ID>, completed=False)
   if len(steps['next_steps']) == 0:
       # All done!
   ```

2. **Mark milestone complete** (user runs):
   ```bash
   chronicle milestone-complete <ID>
   ```

3. **Auto-generates documentation** by querying:
   ```python
   milestone = mcp__chronicle__get_milestone(<ID>)
   # Has all linked sessions, commits, duration
   # Can auto-update DEVELOPMENT_HISTORY.md or export to Obsidian
   ```

## Querying Examples

### "What features are in progress?"
```python
milestones = mcp__chronicle__get_milestones(status="in_progress")
for m in milestones['milestones']:
    sessions = len(m['related_sessions'])
    print(f"{m['title']}: {sessions} sessions so far")
```

### "What's the highest priority work?"
```python
roadmap = mcp__chronicle__get_roadmap()
top_planned = roadmap['planned_high_priority'][0]
print(f"Next up: {top_planned['title']} (P{top_planned['priority']})")
```

### "Show me all optimization work"
```python
milestones = mcp__chronicle__get_milestones(milestone_type="optimization")
```

### "What work did session 16 contribute to?"
```python
# Get all milestones
all_milestones = mcp__chronicle__get_milestones(limit=100)
for m in all_milestones['milestones']:
    if 16 in m['related_sessions']:
        print(f"Session 16 worked on: {m['title']}")
```

## Statistics & Reports

### Weekly Progress Report
```python
roadmap = mcp__chronicle__get_roadmap(days=7)

completed_count = len(roadmap['recently_completed'])
in_progress_count = len(roadmap['in_progress'])

print(f"Week of {date}:")
print(f"✅ {completed_count} milestones completed")
print(f"🚧 {in_progress_count} milestones in progress")
print(f"⏰ {roadmap['summary']['total_next_steps'] - roadmap['summary']['completed_next_steps']} pending tasks")
```

### Milestone Velocity
```python
# Get all completed milestones
completed = mcp__chronicle__get_milestones(status="completed", limit=100)

# Calculate average time from creation to completion
durations = []
for m in completed['milestones']:
    created = datetime.fromisoformat(m['created_at'])
    completed_at = datetime.fromisoformat(m['completed_at'])
    durations.append((completed_at - created).days)

avg_days = sum(durations) / len(durations)
print(f"Average milestone completion time: {avg_days:.1f} days")
```

## Auto-Documentation Pattern

Instead of manually updating DEVELOPMENT_HISTORY.md:

```python
# Query completed milestones
completed = mcp__chronicle__get_milestones(status="completed")

# For each milestone, get details
for milestone in completed['milestones']:
    details = mcp__chronicle__get_milestone(milestone['id'])

    # Extract:
    # - Title, description
    # - Related sessions (with summaries)
    # - Related commits (with messages)
    # - Duration (from session data)
    # - Files modified (from commits)

    # Generate markdown section
    md = f"### {details['title']}\n"
    md += f"{details['description']}\n\n"
    md += f"**Status**: {details['status']}\n"
    md += f"**Sessions**: {len(details['linked_sessions'])}\n"
    md += f"**Commits**: {len(details['linked_commits'])}\n"

    # Could write to DEVELOPMENT_HISTORY.md or Obsidian
```

## Integration with Other Skills

### With chronicle-workflow
After completing a session, use this skill to:
- Link session to active milestone
- Mark next steps as complete
- Check roadmap for what to work on next

### With chronicle-session-documenter
When documenting a session to Obsidian:
- Include milestone information
- Add wikilinks to related milestones
- Tag with milestone tags

### With chronicle-context-retriever
When searching past work:
- Filter by milestone
- Find all sessions for a feature
- See historical progress on similar work

## CLI Commands Reference

**Milestones:**
```bash
chronicle milestone "Title" --description "Desc" --type feature --priority 1 --tags "tag1,tag2"
chronicle milestones --status in_progress
chronicle milestone-show <ID>
chronicle milestone-status <ID> in_progress

chronicle next-step-complete <ID>
```

**Linking:**
```bash
chronicle link-session <session_id> --milestone <ID>
```

**Roadmap:**
```bash
chronicle roadmap --days 7
```

## Database Tables

### project_milestones
- `id` - Unique ID
- `title` - Milestone name
- `description` - Details
- `status` - planned, in_progress, completed, archived
- `milestone_type` - feature, bugfix, optimization, documentation
- `priority` - 1 (highest) to 5 (lowest)
- `created_at` - Creation timestamp
- `completed_at` - Completion timestamp
- `related_sessions` - JSON array of session IDs
- `related_commits` - JSON array of commit SHAs
- `tags` - JSON array of tags

### next_steps
- `id` - Unique ID
- `description` - What needs to be done
- `priority` - 1 (highest) to 5 (lowest)
- `estimated_effort` - small, medium, large
- `category` - feature, optimization, fix, docs
- `created_by` - session_16, manual, ai-suggestion
- `completed` - 0 or 1
- `created_at` - Creation timestamp
- `completed_at` - Completion timestamp
- `related_milestone_id` - FK to milestone

## Pro Tips

1. **Start milestones early** - Link sessions as you go
2. **Use priority levels** - Helps roadmap show what's important
3. **Tag milestones** - Makes filtering easier (e.g., "phase-5", "api", "frontend")
4. **Break down features** - Create next steps for each milestone
5. **Link sessions retroactively** - After work is done, link to milestone
6. **Query before planning** - Check roadmap to avoid duplicate work
7. **Use milestone types** - Distinguishes features from bugfixes
8. **Complete next steps** - Helps track progress within a milestone
9. **Auto-document** - Query completed milestones to generate reports
10. **Review roadmap weekly** - Stay aligned on priorities

## Benefits Over Manual Documentation

**Before (manual DEVELOPMENT_HISTORY.md):**
- Manual updates required
- Easy to forget to document
- Hard to query programmatically
- No linking between sessions/commits/features
- Becomes stale quickly

**After (database-tracked milestones):**
- Automatic tracking via MCP tools
- Queryable (e.g., "what's in progress?")
- Sessions auto-link to milestones
- Commits auto-link to sessions
- Real-time roadmap view
- Can generate reports on-demand
- Powers AI-driven development insights

## Example: Meta-Development

Chronicle uses Chronicle to track its own development:

```bash
# Milestone #1: Add project tracking to Chronicle
chronicle milestone "Add project tracking to Chronicle" \
  --description "Database-tracked milestones and next steps" \
  --type feature \
  --priority 1 \
  --tags "phase-5,project-tracking,meta"

# Break down work
chronicle next-step "Design database schema" --priority 1 --effort medium --milestone 1
chronicle next-step "Add CLI commands" --priority 1 --effort large --milestone 1
chronicle next-step "Add MCP tools" --priority 1 --effort medium --milestone 1
chronicle next-step "Create Chronicle Skills" --priority 2 --effort medium --milestone 1
chronicle next-step "Write tests" --priority 2 --effort small --milestone 1
chronicle next-step "Update documentation" --priority 3 --effort small --milestone 1

# Mark in progress
chronicle milestone-status 1 in_progress

# As work completes
chronicle next-step-complete 1
chronicle next-step-complete 2
# ... etc

# Link current session
chronicle link-session 18 --milestone 1

# When done
chronicle milestone-complete 1

# Generate report
chronicle milestone-show 1
```

This skill represents Chronicle's dogfooding: using Chronicle to build Chronicle!
