Version control isn't just for code anymore. When implementing Context as Code, version control becomes the nervous system that coordinates context evolution across your entire system. Here's how to do it right.
## Core Integration Patterns
### Git-Native Context Storage
// Repository Structure
repo/
├── .git/
├── src/
│ └── services/
├── .cac/ # Context root
│ ├── schemas/
│ │ └── v1/
│ ├── contexts/
│ │ ├── system.cac.ts
│ │ └── services/
│ └── .cacignore # Context ignore file
└── .github/
└── workflows/
└── context-validation.yml
### Context Change Workflow
// context-change.cac.ts
export const ContextChange = {
type: "update",
component: "PaymentService",
changes: {
before: {
sla: "99.9%",
dependencies: ["UserService"]
},
after: {
sla: "99.99%",
dependencies: ["UserService", "FraudService"]
},
impact_analysis: {
affected_services: ["OrderService", "BillingService"],
required_approvers: ["platform-team", "security-team"]
}
}
}
## Git Hooks Integration
#!/bin/bash
# .git/hooks/pre-commit
# Validate context files
echo "Validating context changes..."
cac validate $(git diff --cached --name-only | grep .cac.ts)
# Generate context dependency graph
echo "Updating context graph..."
cac graph-generate
# Ensure context-code consistency
echo "Checking context-code consistency..."
cac verify-alignment
## Pull Request Automation
# .github/workflows/context-pr.yml
name: Context PR Validation
on:
pull_request:
paths:
- '**.cac.ts'
- '.cac/**'
jobs:
validate-context:
runs-on: ubuntu-latest
steps:
- name: Check Schema Validity
run: cac validate-schema
- name: Generate Impact Report
run: |
cac impact-analysis > impact.md
echo "### Impact Analysis" >> $GITHUB_STEP_SUMMARY
cat impact.md >> $GITHUB_STEP_SUMMARY
- name: Verify Required Approvers
run: cac check-approvers
- name: Update Context Graph
run: cac update-graph
## Branch Protection Rules
// branch-rules.cac.ts
export const ContextBranchRules = {
protected_patterns: [
"main",
"release/*",
"context/*"
],
rules: {
context_files: {
required_reviewers: 2,
required_teams: ["architecture", "tech-leads"],
block_on_validation_failure: true
},
schema_files: {
required_reviewers: 3,
required_teams: ["platform", "architecture"],
prevent_direct_push: true
}
}
}
## Conflict Resolution
// conflict-resolution.cac.ts
export const ContextMergeStrategy = {
resolution_rules: {
sla: "keep_higher",
dependencies: "union",
security_requirements: "most_strict",
custom_resolvers: {
business_rules: (current: Rule[], incoming: Rule[]) => {
// Custom merge logic
return mergedRules;
}
}
}
}
## Change History Tracking
// history-tracking.cac.ts
export const ContextHistory = {
tracking: {
metadata: {
store_with_commit: true,
changelog_format: "conventional-commits",
link_to_issues: true
},
retention: {
keep_versions: "unlimited",
archive_after: "1 year",
archive_storage: "cold-storage"
}
},
audit: {
track_viewers: true,
track_changes: true,
track_queries: true
}
}
## Review Process Integration
// review-process.cac.ts
export const ContextReview = {
automaticChecks: {
schema_validation: true,
impact_analysis: true,
dependency_check: true,
security_implications: true
},
requiredArtifacts: {
impact_report: true,
migration_plan: "if_breaking_change",
rollback_plan: true
},
reviewers: {
technical: {
minimum: 2,
must_include: ["service_owner", "architect"]
},
business: {
minimum: 1,
must_include: ["product_owner"]
}
}
}
## Continuous Integration Workflows
# context-ci.yml
name: Context CI
on: [push, pull_request]
jobs:
context-validation:
runs-on: ubuntu-latest
steps:
- name: Validate Context Changes
uses: cac/validator@v1
with:
rules: .cac/validation-rules.yml
- name: Generate Documentation
if: success()
uses: cac/docs-generator@v1
- name: Update Context Graph
if: success()
uses: cac/graph-updater@v1
- name: Notify Stakeholders
if: failure()
uses: actions/notify@v1
with:
channel: "#context-alerts"
## Version Control Best Practices
1. **Atomic Context Changes**
// Single responsibility principle for context changes
@ContextChange({
scope: "PaymentService.SecurityContext",
reason: "Updated PCI compliance requirements",
atomic: true
})
2. **Change Documentation**
// Conventional commits for context
feat(context): add latency SLO to payment service
fix(context): correct dependency graph for order service
docs(context): clarify authentication requirements
breaking(context): update compliance requirements
3. **Context Branching Strategy**
main
├── context/feature/add-new-service
├── context/fix/update-sla
└── context/refactor/reorganize-domains
4. **Automated Validation**
// pre-merge-validation.cac.ts
export const PreMergeChecks = {
validators: [
"schema-compliance",
"dependency-cycle-check",
"security-requirements",
"sla-validation"
],
approvals: {
technical: 2,
business: 1
},
automated_fixes: {
formatting: true,
reference_updates: true
}
}
## Integration Principles
1. **Consistency First**
- Context changes must be atomic
- Automated validation on every change
- Enforced review processes
2. **Traceability**
- Link context changes to code changes
- Maintain clear change history
- Track context evolution
3. **Automation**
- Automated validation
- Automated impact analysis
- Automated documentation updates
4. **Governance**
- Clear ownership and approval processes
- Strict protection for critical context
- Audit trails for all changesBy Eduarda Ferreira
