Workflow

Step 1: Gather Context

# Recent commits
git log --format="- \`%h\` (%ad) %s" --date=format:"%H:%M" -5

# Recent issues (if gh available)
gh issue list --limit 5 --json number,createdAt 2>/dev/null | jq -r '.[] | "- #\(.number) (\(.createdAt[:10]))"'

# Related files
grep -r "[feature keyword]" --include="*.md" -l | head -5

Step 2: Create Plan

File output:

mkdir -p plans
cat > "plans/$(date +%Y-%m-%d)_[feature-slug].md" << 'EOF'
# Plan: [Feature Name]

Plan Structure

Every plan includes:

1. Context - Recent commits, related files
2. Problem - What needs solving
3. Solution - Approach
4. Steps - Actionable checklist
5. Files - What will be touched

GitHub-Optional Design

Feature	With GitHub	Without GitHub
Output	Issue or file	File only
Context	Issues + commits	Commits only
Tracking	Issue checkboxes	File checkboxes

Agent works in both modes. Plans are useful anywhere.
