Roadmap

Core responsibilities:

• Read SPEC.md and extract all requirements
• Group requirements into logical phases
• Order phases by dependency (what must come first)
• Ensure 100% requirement coverage

Flow: Read Spec → Group → Order → Write

• ./.gtd/<task_name>/SPEC.md — Must exist and be FINALIZED

Output:

• ./.gtd/<task_name>/ROADMAP.md

Phases Are Deliverables

Each phase should produce something usable or testable. Not "Phase 1: Research" — that's an activity, not a deliverable.

Good: "Phase 1: Basic API endpoint that returns hardcoded data" Bad: "Phase 1: Set up project structure"

Dependency-Driven Order

Phase 2 should depend on Phase 1. If phases can be done in any order, they might be the same phase.

Small Phases, Fast Feedback

3-5 phases is ideal. Each phase: 1-3 plans. Each plan: 2-3 tasks.

1. Validate Spec Exists

Bash:

if ! grep -q "FINALIZED" "./.gtd/<task_name>/SPEC.md" 2>/dev/null; then
    echo "Error: SPEC.md must exist and be FINALIZED"
    exit 1
fi

2. Extract Requirements

Read ./.gtd/<task_name>/SPEC.md and list all must have and nice to have.

Create a mental checklist:

• Must have 1
• Must have 2
• ...
• Nice to have 1
• ...

3. Group into Phases

For each criterion, ask:

• What must exist for this to work?
• What does this enable?

Group related criteria into phases.

4. Order by Dependency

Arrange phases so each builds on the previous:

1. Foundation (what everything else needs)
2. Core features (main value)
3. Polish/edge cases (refinement)

5. Write ROADMAP.md

Write to ./.gtd/<task_name>/ROADMAP.md:

# Roadmap

**Spec:** ./.gtd/<task_name>/SPEC.md
**Goal:** {goal}
**Created:** {date}

## Must-Haves

- [ ] {must-have 1}
- [ ] {must-have 2}

## Nice-To-Haves

- [ ] {nice-to-have 1}
- [ ] {nice-to-have 2}

## Phases

<must-have>

### Phase 1: {name}

**Status**: ⬜ Not Started
**Objective**: {description}

### Phase 2: {name}

**Status**: ⬜ Not Started
**Objective**: {description}

...
</must-have>

<nice-to-have>

### Phase n (optional): {name}

**Status**: ⬜ Not Started
**Objective**: {description}
</nice-to-have>
