Roadmap Skill

Plan project execution by creating milestones and organizing PRDs into an executable queue.

Workspace Mode Note

When running in workspace mode, all paths are relative to .aha-loop/ directory:

•Vision analysis: .aha-loop/project.vision-analysis.md
•Architecture: .aha-loop/project.architecture.md
•Roadmap: .aha-loop/project.roadmap.json
•PRD files: .aha-loop/tasks/

The orchestrator will provide the actual paths in the prompt context.

The Job

•Read project.vision-analysis.md and project.architecture.md
•Decompose project into milestones
•Break each milestone into PRDs
•Order PRDs by dependencies
•Output project.roadmap.json
•Generate initial PRD files in tasks/

Milestone Strategy

Standard Milestone Structure

Milestone	Focus	Goal
M0: Foundation	Project scaffolding, CI/CD, tooling	Development environment ready
M1: MVP	Core features only	Minimal usable product
M2: Essential	Important features	Feature-complete for basic use
M3: Enhanced	Nice-to-have features	Polished product
M4: Optimization	Performance, UX polish	Production-ready

Milestone Sizing

Each milestone should:

•Be completable in a reasonable timeframe
•Have 3-7 PRDs (avoid too many or too few)
•Deliver tangible, testable value
•Build on previous milestones

PRD Decomposition

From Features to PRDs

For each milestone, break down features into PRDs:

code

Milestone: M1 - MVP
├── PRD-001: Project Scaffolding
├── PRD-002: Database Schema
├── PRD-003: Core Data Models
├── PRD-004: Basic API Endpoints
└── PRD-005: Minimal UI

PRD Sizing

Each PRD should:

•Take 1-5 Aha Loop iterations (5-25 stories)
•Focus on one coherent feature area
•Be independently testable
•Not depend on unfinished PRDs

PRD Ordering

Order PRDs by dependencies:

•Infrastructure first - Project setup, database, auth
•Backend before frontend - APIs before UI that uses them
•Core before optional - Must-have before nice-to-have
•Data before presentation - Models before views

Roadmap Creation Process

Step 1: Analyze Requirements

From vision analysis, categorize features:

markdown

## Feature Categories

### M1: MVP (Must ship)
- [Feature 1]
- [Feature 2]

### M2: Essential (Should ship)
- [Feature 3]
- [Feature 4]

### M3: Enhanced (Nice to ship)
- [Feature 5]

Step 2: Create M0 Foundation

Every project starts with M0:

markdown

## M0: Foundation PRDs

### PRD-001: Project Scaffolding
- Initialize project with chosen tech stack
- Set up directory structure
- Configure linting and formatting
- Set up basic CI (if applicable)
- Create initial README

### PRD-002: Development Environment
- Database setup (if applicable)
- Environment configuration
- Development scripts
- Basic testing infrastructure

Step 3: Decompose Milestones into PRDs

For each milestone after M0:

•List all features for this milestone
•Group related features
•Order by dependencies
•Create PRD for each group
•Estimate stories per PRD

Step 4: Generate PRD Files

For each PRD, create a stub file in tasks/:

markdown

# PRD: [Title]

**ID:** PRD-XXX
**Milestone:** M[N]
**Status:** Pending

## Overview

[Brief description from roadmap]

## Context

[How this relates to previous PRDs and the overall project]

## Goals

- [Goal 1]
- [Goal 2]

## User Stories

[To be generated when this PRD becomes active]

## Dependencies

- PRD-XXX: [What it depends on]

## Acceptance Criteria

- [ ] [High-level criterion]
- [ ] [Another criterion]

---

*This PRD will be fully expanded when it becomes the active PRD.*

Dynamic Roadmap Updates

When to Update Roadmap

The roadmap should be updated when:

•PRD Completed - Mark as complete, update timestamps
•New Requirement Discovered - Add new PRD
•Scope Change - Modify or remove PRDs
•Better Approach Found - Restructure PRDs
•Milestone Complete - Update status, move to next

Update Process

json

{
  "changelog": [
    {
      "timestamp": "2026-01-29T12:00:00Z",
      "action": "prd_completed",
      "prdId": "PRD-002",
      "description": "Database schema implemented"
    },
    {
      "timestamp": "2026-01-29T14:00:00Z",
      "action": "prd_added",
      "prdId": "PRD-007",
      "description": "Added caching layer PRD based on performance research"
    }
  ]
}

Automatic Triggers

The orchestrator should trigger roadmap review:

•After each PRD completion
•After each milestone completion
•When significant learnings are recorded
•When errors repeatedly occur

Integration with Orchestrator

Orchestrator Reads

bash

# Get current PRD
jq '.currentPRD' project.roadmap.json

# Get PRD file path
jq -r '.milestones[].prds[] | select(.id == "PRD-002") | .prdFile' project.roadmap.json

Orchestrator Updates

After PRD completion:

bash

# Update PRD status
jq '.milestones[].prds[] |= if .id == "PRD-002" then .status = "completed" else . end' project.roadmap.json

PRD Queue Management

Getting Next PRD

python

# Pseudocode for finding next PRD
def get_next_prd(roadmap):
    for milestone in roadmap.milestones:
        if milestone.status == "completed":
            continue
        for prd in milestone.prds:
            if prd.status == "pending":
                if all_dependencies_complete(prd):
                    return prd
    return None  # All complete or blocked

Handling Blocked PRDs

If a PRD's dependencies aren't met:

•Skip to next available PRD
•If no PRDs available, report blocking issue
•Consider if dependencies need reprioritization
