Update Sprint $0 Context

Regenerate sprint context files for Sprint $0 based on current project state.

When to Update

• •After Wave 1 completes (often creates foundation)
• •When new ADRs are created
• •When database schema changes
• •When architecture patterns evolve
• •When implementers report missing context
• •Before starting a new wave

Current Context

Existing CONTEXT.md Summary

!cat .arch/sprints/sprint-$0/CONTEXT.md 2>/dev/null | head -80 || echo "No context file found"!

Recent Changes

New ADRs (check for additions)

!ls -lt .arch/decisions/ 2>/dev/null | head -5!

Recent Migrations (if applicable)

!ls -lt migrations/ 2>/dev/null | head -5 || ls -lt db/migrations/ 2>/dev/null | head -5 || echo "No migrations directory found"!

Recent Git Changes

!git log --oneline -10 2>/dev/null || echo "Not a git repository"!

Your Task

Step 1: Verify Sprint Exists

1. •Check .arch/sprints/sprint-$0.md exists
2. •Check .arch/sprints/sprint-$0/ directory exists
3. •If not found, error: use /init-sprint $0 instead

Step 2: Analyze Current Project State

Scan the project for updates:

Database Schema

• •Check migrations/ for recent changes
• •Examine ORM models (e.g., models/, domain/, entities/)
• •Compare with current CONTEXT.md

Architecture

• •Check for new files/directories
• •Review package structure changes
• •Check for new configuration files

ADRs

• •Read any ADRs created after sprint started
• •Compare with CONTEXT.md ADRs section

API Changes

• •Check for new endpoints
• •Review API documentation changes

Dependencies

• •Check package.json, go.mod, requirements.txt
• •Look for new external service integrations
• •Check .env.example for new variables

Tests

• •Check for new test patterns
• •Review coverage changes

Step 3: Update CONTEXT.md

Update .arch/sprints/sprint-$0/CONTEXT.md:

1. •Database Schema: Add new tables, update changed ones
2. •Architecture Overview: Update tech stack, patterns
3. •Key ADRs: Add new ADRs created during sprint
4. •API Contracts: Add new endpoints
5. •Dependencies: Add new services, variables
6. •Code Patterns: Add new patterns introduced
7. •Common Gotchas: Add issues discovered
8. •Last Updated: Update timestamp

Step 4: Check DEPENDENCY-GRAPH.md

If RFC dependencies changed:

1. •Rebuild dependency graph
2. •Recalculate wave assignments
3. •Update mermaid diagram
4. •Recalculate critical path
5. •Update change log

Step 5: Sync Sprint Main File

Update .arch/sprints/sprint-$0.md:

1. •Sprint Context section
2. •Parallelization Plan (if deps changed)
3. •Progress Metrics

Step 6: Validate Consistency

• •RFCs listed match DEPENDENCY-GRAPH.md
• •Wave assignments are consistent
• •Links point to existing files
• •No placeholder data remains

Step 7: Generate Update Report

Important Notes

Update, Don't Regenerate

• •Preserve manual additions
• •Add to existing sections
• •Only replace clearly outdated content

Be Specific

❌ "We use PostgreSQL" ✅ "PostgreSQL 15 with GORM, migrations in migrations/, pool size 20"

Coordinate with Active Work

If sprint is in progress:

• •Check WAVE-STATUS.md for active RFCs
• •Consider impact on in-progress work
• •Communicate significant changes
