Workflow

Phase 1: Context Discovery & Intent Recognition

Objective: Understand project structure and user's specific milestone intent.

Steps:

Locate project RULE.md and milestones.yaml:

ls RULE.md milestones.yaml

Read both files:

• RULE.md: Project methodology, milestone tracking preferences

• milestones.yaml: Existing milestones and structure

Detect user intent:

• Create milestone: "create milestone", "add milestone", "new milestone"

• Update milestone: "update milestone", "milestone progress", "mark complete"

• Check status: "milestone status", "show milestones", "timeline"

• Manage dependencies: "milestone depends on", "blocking milestone"

Route to appropriate workflow:

• Create → Workflow A

• Update → Workflow B

• Status → Workflow C

• Dependencies → Workflow D

Workflow A: Create Milestone

Objective: Add a new milestone to the project timeline.

Steps:

Gather milestone details:

Name:

Milestone name? Example: "Beta Release", "MVP Launch", "Security Audit Complete"

Description:

Brief description of what this milestone represents?

Target date:

Target completion date? (YYYY-MM-DD or relative like "end of Q2")

Deliverables:

What needs to be delivered for this milestone?

• Deliverable 1
• Deliverable 2

Owner (optional):

Who's responsible for this milestone? (@name or "Team")

Dependencies (optional):

Does this milestone depend on any other milestones? Example: "After Alpha Release" or "After milestones 1 and 2"

Related sprints/phases (optional):

Which sprints/phases contribute to this milestone?

Generate milestone ID:

milestone-{number} or {name-slug} Example: milestone-1 or beta-release

Read current milestones.yaml:

Read milestones.yaml

Add new milestone entry:

milestones:

• id: {milestone-id} name: "{Milestone Name}" description: "{Description}" target_date: YYYY-MM-DD actual_date: null status: planned dependencies: [{dependent-milestone-ids}] deliverables:

  • Deliverable 1
  • Deliverable 2 owner: "@{name}" related_sprints: [{sprint-numbers}] completion_criteria:
  • Criterion 1
  • Criterion 2 notes: ""

Validate dependencies:

• Check that referenced milestones exist

• Detect circular dependencies

• Warn if dependency order seems wrong

Update milestones.yaml using Edit tool:

Edit milestones.yaml Add new milestone entry in appropriate location (sorted by target date)

Update governance:

• Update project README.md (add to timeline section)

• Add "Recent Activity" entry

• Link to related sprints if applicable

Report creation:

✅ Milestone Created!

🎯 {Milestone Name} 📅 Target: {target_date} 📦 Deliverables: {count} 👤 Owner: @{name}

[If dependencies:] 🔗 Dependencies:

• {Dependent milestone names}

[If related sprints:] 🏃 Related Sprints: {sprint numbers}

📄 Added to: milestones.yaml

💡 Track progress with: "Update milestone {name}" "Milestone status"

Workflow B: Update Milestone

Objective: Update milestone status, progress, or completion.

Steps:

Identify target milestone:

• Extract name/ID from user message

• Or ask: "Which milestone?"

Read milestones.yaml:

Read milestones.yaml Find milestone entry

Determine update type:

• Status change: planned → in_progress → completed → delayed

• Progress update: Update notes or deliverables status

• Date change: Update target or actual date

• Completion: Mark as completed with date

Execute update:

For status change:

status: {new_status}

For completion:

status: completed actual_date: {YYYY-MM-DD}

For progress/notes:

notes: "{Updated notes about progress}"

For deliverable tracking:

deliverables:

• Deliverable 1 (completed)

• Deliverable 2 (in progress)

Check impact:

• If milestone completed: Check dependent milestones (can they start?)

• If milestone delayed: Check impacted milestones (cascade delays?)

Update milestones.yaml using Edit tool

Generate milestone report (if completed):

Milestone Completion Report: {Milestone Name}

Completed: {actual_date} Target: {target_date} ({"On Time" | "Early" | "Delayed by X days"})

Deliverables

• Deliverable 1
• Deliverable 2

Contributing Sprints

• Sprint {X}
• Sprint {Y}

Metrics

• Duration: {calculation}
• Team: {involved team members}
• Key Achievements: {summary}

Impact

• Enabled milestones: {dependent milestones}
• Next milestone: {next in timeline}

Lessons Learned

{Notes from milestone execution}

Generated: {YYYY-MM-DD} by ProjectMaster

Save report (if generated):

Write to: reports/milestone-{id}-completion.md

Update governance:

• Update project README.md

• Add Recent Activity entry

• Link report to milestone in yaml

Report update:

✅ Milestone Updated!

🎯 {Milestone Name} 📊 Status: {old_status} → {new_status}

[If completed:] 🎉 Milestone Completed! 📅 Completed: {actual_date} ({on_time_status}) 📦 Deliverables: All {count} delivered 📄 Report: reports/milestone-{id}-completion.md

🔓 Unblocked Milestones:

• {Dependent milestone names}

💡 Next Milestone: {Next in timeline}

[If delayed:] ⚠️ Milestone Delayed 📅 Was: {original_target} → Now: {new_target} ⚠️ Impacted Milestones:

• {Affected milestones}

📄 Updated: milestones.yaml

Workflow C: Status Report

Objective: Show project milestone status and timeline.

Steps:

Read milestones.yaml:

Read milestones.yaml Parse all milestones

Categorize milestones:

• Completed

• In Progress

• Planned

• Delayed/At Risk

Calculate metrics:

• Total milestones

• Completion rate

• On-time rate

• Average delay (if any)

• Next milestone due date

Check dependencies:

• Any blocked milestones?

• Ready to start milestones?

Generate status report:

📊 Project Milestone Status

Project: {Project Name} Total Milestones: {count} Completed: {X}/{total} ({percentage}%) On Track: {Y} At Risk: {Z}

🎉 Completed Milestones: ✅ {Milestone 1} - {actual_date} ({"On Time" | "Early" | "Delayed"}) ✅ {Milestone 2} - {actual_date} ...

🔄 In Progress:

• {Milestone Name} - Target: {target_date} ({days_remaining} days) Status: {On Track | At Risk} Progress: {notes or deliverables status}

📅 Upcoming:

• {Milestone Name} - Target: {target_date} ({days_until} days) [If blocked:] ⚠️ Blocked by: {dependency names}

⚠️ Delayed:

• {Milestone Name} - Was: {original} Now: {revised} Delay: {days} days Impact: {affected milestones}

📈 Timeline Health: {Overall Assessment} [If at risk:] ⚠️ {count} milestones at risk of delay

🎯 Next Milestone: {Name} - {target_date} ({days_remaining} days)

📄 Full timeline: milestones.yaml

Include visual timeline (text-based):

📅 Timeline:

Q1 2025 ├── [✅] Alpha Release (2025-02-15) ← Completed └── [🔄] Beta Release (2025-03-31) ← In Progress

Q2 2025 ├── [📅] Public Launch (2025-04-30) └── [⏸️] Feature Freeze (2025-05-15) ← Blocked by Beta

Q3 2025 └── [📅] 1.0 Release (2025-07-31)

Workflow D: Manage Dependencies

Objective: Define or update milestone dependencies.

Steps:

Identify milestones involved:

• Primary milestone

• Dependent milestone(s)

Read milestones.yaml

Update dependency:

Adding dependency:

milestones:

• id: milestone-2 dependencies: [milestone-1] # milestone-2 depends on milestone-1

Removing dependency:

dependencies: [] # or remove the dependency from list

Validate:

• Check for circular dependencies

• Verify dependency exists

• Check timeline logic (dependent milestone should be after dependency)

Update milestones.yaml

Report:

✅ Dependency Updated!

🎯 {Milestone Name} 🔗 Now depends on:

• {Dependency 1}
• {Dependency 2}

⚠️ {Milestone Name} cannot start until dependencies complete.

[If circular dependency detected:] ❌ Error: Circular dependency detected! {Milestone A} → {Milestone B} → {Milestone A} Please review dependencies.

[If timeline conflict:] ⚠️ Warning: {Milestone Name} target ({date1}) is before dependency {Dependency Name} target ({date2}). Consider adjusting dates.

Special Cases

Case 1: Milestone with multiple dependencies

milestones:

• id: public-launch name: "Public Launch" dependencies: [beta-complete, security-audit, marketing-ready] status: planned

Report readiness:

🎯 Public Launch Readiness:

Dependencies: ✅ Beta Complete (2025-03-15) ← Done ✅ Security Audit (2025-03-20) ← Done 🔄 Marketing Ready (2025-04-01) ← In Progress (90%)

Status: Waiting on 1 dependency Can start: After 2025-04-01

Case 2: Milestone delayed - cascade impact

If milestone delayed, check cascade:

⚠️ Milestone Delay Impact Analysis

{Delayed Milestone} delayed from {old_date} to {new_date}

Directly Impacted:

• {Milestone A} (depends on this) - May delay
• {Milestone B} (depends on this) - May delay

Cascade Impact:

• {Milestone C} (depends on Milestone A) - Potential delay
• {Milestone D} (depends on Milestone B) - Potential delay

Recommendation: Review timeline for {count} affected milestones. Consider:

1. Adjusting target dates
2. Removing dependencies if possible
3. Allocating more resources

Case 3: Sprint-to-milestone tracking

Link sprints to milestone progress:

Milestone: Beta Release

Target: 2025-03-31 Status: In Progress (75%)

Contributing Sprints:

• Sprint 3: User Authentication ✅ Complete
• Sprint 4: Profile Management ✅ Complete
• Sprint 5: Settings & Preferences 🔄 In Progress (Day 8/14)
• Sprint 6: Final Polish 📅 Planned

Deliverables Status:

• Core Features (Sprints 3-4)
• [🔄] Additional Features (Sprint 5) - 80% complete
• Bug Fixes & Polish (Sprint 6)

Progress: 75% (3 of 4 sprints complete) On Track: Yes, 2 weeks remaining

Case 4: Milestone-based releases

For release milestones, include version info:

milestones:

• id: v1-0-release name: "Version 1.0 Release" type: release version: "1.0.0" target_date: 2025-07-31 release_notes: "reports/v1.0-release-notes.md" deliverables:
  • All MVP features complete
  • Security audit passed
  • Documentation published
  • Marketing materials ready

Best Practices

1. Define clear deliverables

Each milestone should have specific, measurable deliverables.

2. Set realistic dates

Use team velocity and sprint history to set achievable targets.

3. Track dependencies explicitly

Don't assume implicit dependencies - document them.

4. Review timeline regularly

Monthly or per-sprint review of milestone status keeps project on track.

5. Celebrate completions

Acknowledge milestone achievements with team.

6. Learn from delays

Document reasons for delays to improve future planning.

7. Link to work items

Connect milestones to sprints, stories, and tasks for full traceability.

8. Update proactively

Update milestone status before it becomes "delayed".

Notes

• Milestones provide high-level project visibility for stakeholders.

• Dependency tracking prevents surprises and enables proactive planning.

• Milestone completion reports create valuable project history.

• Integration with sprints connects strategy (milestones) with execution (sprints).

• The milestones.yaml becomes the project timeline source of truth.

Well-managed milestones turn long-term goals into achievable checkpoints. This Skill makes milestone tracking systematic and insightful.
