## Task Details

### Operational Requirements

{OPERATIONAL_REQUIREMENTS}

### Technical Context

**Current Infrastructure:**
{CURRENT_INFRASTRUCTURE}

**Services Involved:**
{SERVICES}

**Dependencies:**
{DEPENDENCIES}

## Documentation & API Research (MANDATORY)

Before implementing infrastructure changes, research the current state:

- [ ] Identified current versions of infrastructure tools/platforms in use
- [ ] Used WebSearch to find current documentation (within last 12 months):
  - Search: "{tool/platform} {version} documentation"
  - Search: "{tool/platform} latest features 2025"
  - Search: "{tool/platform} breaking changes changelog"
  - Search: "{cloud-provider} best practices 2025"
- [ ] Reviewed recent deprecations, security updates, or new capabilities
- [ ] Documented findings to inform infrastructure decisions

**Why this matters:** Model knowledge cutoff is January 2025. Infrastructure platforms evolve rapidly. Implementing based on outdated understanding leads to deprecated configurations, security vulnerabilities, or missed optimization opportunities.

**Query Templates:**
```bash
# For Kubernetes/Docker
WebSearch "Kubernetes 1.31 new features official docs"
WebSearch "Docker Compose v2 vs v3 breaking changes"

# For Cloud Providers
WebSearch "AWS ECS Fargate 2025 best practices"
WebSearch "GitHub Actions runner latest version features"

# For CI/CD Tools
WebSearch "Terraform 1.9 provider updates"
WebSearch "GitHub Actions 2025 security hardening guide"
```

**What to look for:**
- Current recommended versions (not what model remembers)
- Recent security patches (implement latest secure configurations)
- Deprecated APIs/configurations (don't use outdated patterns)
- New features (leverage latest capabilities for efficiency)
- Breaking changes (understand migration requirements)

---

## Git/GitHub Setup (For Infrastructure PRs)

Infrastructure changes (IaC, CI/CD configs, deployment scripts) require careful version control:

**If creating any infrastructure PR, follow these rules:**

1. **Check project conventions FIRST:**
   ```bash
   ls .github/PULL_REQUEST_TEMPLATE.md
   cat CONTRIBUTING.md
   ```

2. **Create feature branch (NEVER commit to main/master/develop):**
   ```bash
   git checkout -b infra/{feature-name}
   # OR
   git checkout -b ci/{pipeline-name}
   # OR
   git checkout -b deploy/{deployment-change}
   ```

3. **Create DRAFT PR at task START (not task end):**
   ```bash
   gh pr create --draft --title "[INFRA] {title}" --body "Infrastructure change in progress"
   # OR
   gh pr create --draft --title "[CI/CD] {title}" --body "Pipeline change in progress"
   ```

4. **Prefer `gh` CLI over `git` commands** for GitHub operations:
   ```bash
   gh pr ready        # Mark PR ready for review
   gh pr checks       # View CI status
   gh pr merge        # Merge after approval
   ```

**Reference:** `wolf-workflows/git-workflow-guide.md` for detailed Git/GitHub workflow

**Infrastructure-Specific PR Naming:**
- `[INFRA]` - Infrastructure as Code changes
- `[CI/CD]` - Pipeline/workflow changes
- `[DEPLOY]` - Deployment configuration changes
- `[MONITOR]` - Monitoring/alerting changes

---

## Incremental Infrastructure Changes (MANDATORY)

Break infrastructure work into small, safe increments to minimize risk:

### Incremental Infrastructure Guidelines

1. **Each change < 1 day of work** (4-8 hours including testing/validation)
2. **Each change is independently deployable** (can apply to production safely)
3. **Each change has clear rollback plan** (tested rollback procedure)

### Infrastructure Change Patterns

**Pattern 1: Blue-Green Deployment**
```markdown
Increment 1: Deploy new "green" environment (no traffic)
Increment 2: Configure health checks on green environment
Increment 3: Route 10% traffic to green (canary testing)
Increment 4: Route 100% traffic to green, keep blue for rollback
Increment 5: Decommission blue environment after 48h stability
```

**Pattern 2: Feature Flags for Infrastructure**
```markdown
Increment 1: Deploy new infrastructure with feature flag OFF
Increment 2: Enable for internal/staging environments only
Increment 3: Enable for 10% production traffic (canary)
Increment 4: Enable for 100% production traffic
Increment 5: Remove feature flag after validation period
```

**Pattern 3: Layered Infrastructure Changes**
```markdown
Increment 1: Network layer (VPC, subnets, security groups)
Increment 2: Compute layer (EC2, ECS, Kubernetes nodes)
Increment 3: Application layer (containers, services)
Increment 4: Monitoring layer (metrics, logs, alerts)
```

**Pattern 4: Rolling Updates**
```markdown
Increment 1: Update 1 instance/pod, validate health
Increment 2: Update 25% of fleet, monitor for 1 hour
Increment 3: Update 50% of fleet, monitor for 1 hour
Increment 4: Update remaining 50%, full monitoring
Increment 5: Validate all instances healthy, rollback ready for 24h
```

### Why Small Infrastructure Changes Matter

Large infrastructure changes (>1 day) lead to:
- ❌ High blast radius (single change affects many systems)
- ❌ Difficult rollback (many interdependent changes)
- ❌ Long outage windows (big bang deployments)
- ❌ Hard to troubleshoot (too many variables changed at once)

Small infrastructure increments (4-8 hours) enable:
- ✅ Limited blast radius (one change at a time)
- ✅ Simple rollback (revert single change)
- ✅ Zero-downtime deployments (gradual rollout)
- ✅ Easy troubleshooting (isolate which change caused issue)

**Critical Infrastructure Principle:** Never make multiple infrastructure changes simultaneously. Deploy one, validate, then proceed to next.

**Reference:** `wolf-workflows/incremental-pr-strategy.md` for PR size guidance (applies to infrastructure PRs too)

## Task Type

### CI/CD Pipeline

**If creating/modifying GitHub Actions workflow:**

**Mandatory Standards** (per ADR-072):
1. **Checkout Step** (MUST be first):
   ```yaml
   - uses: actions/checkout@v4
   ```

2. **Explicit Permissions**:
   ```yaml
   permissions:
     contents: read
     pull-requests: write
     issues: write
   ```

3. **Correct API Fields**:
   - Use `closingIssuesReferences` not `closes`
   - Use `labels` not `label`

**Workflow Design:**
```yaml
{WORKFLOW_YAML_STRUCTURE}
```

### Infrastructure as Code

**If managing infrastructure:**

**Technologies:**
{IaC_TECHNOLOGY} (e.g., Terraform, CloudFormation, Docker Compose)

**Resources to Manage:**
- {RESOURCE_1}
- {RESOURCE_2}

**Configuration:**
{CONFIGURATION_DETAILS}

### Monitoring & Alerting

**If setting up observability:**

**Metrics to Track:**
- {METRIC_1}: {DESCRIPTION_AND_THRESHOLD}
- {METRIC_2}: {DESCRIPTION_AND_THRESHOLD}

**Alerting Rules:**
- {ALERT_1}: Trigger when {CONDITION}, notify {CHANNEL}
- {ALERT_2}: Trigger when {CONDITION}, notify {CHANNEL}

**Dashboards:**
{DASHBOARD_REQUIREMENTS}

### Deployment Strategy

**Deployment Type:**
{DEPLOYMENT_TYPE} (e.g., blue-green, canary, rolling update, direct)

**Rollback Plan:**
{ROLLBACK_PROCEDURE}

**Health Checks:**
- {HEALTH_CHECK_1}
- {HEALTH_CHECK_2}

## CI/CD Best Practices

### Workflow Design

**Fast Feedback:**
```yaml
# Run fast tests first
- name: Lint
  run: npm run lint

- name: Unit Tests
  run: npm run test:unit

# Then slower tests
- name: Integration Tests
  run: npm run test:integration
  if: success()  # Only if fast tests pass
```

**Fail Fast:**
```yaml
# Stop on first failure
strategy:
  fail-fast: true
```

**Caching:**
```yaml
- uses: actions/cache@v3
  with:
    path: ~/.npm
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
```

**Secrets Management:**
```yaml
env:
  API_KEY: ${{ secrets.API_KEY }}  # Use GitHub secrets
  # NEVER: API_KEY: "hardcoded-key"
```

## Infrastructure Best Practices

### Infrastructure as Code

**Version Control:**
- All infrastructure definitions in git
- Use branches for infrastructure changes
- Review infrastructure changes like code

**Modularity:**
```hcl
# Terraform example - reusable modules
module "vpc" {
  source = "./modules/vpc"
  cidr_block = var.vpc_cidr
}
```

**State Management:**
- Use remote state (S3, Terraform Cloud)
- Enable state locking
- Never commit state files

**Security:**
- Principle of least privilege (minimal IAM permissions)
- Encrypt data at rest and in transit
- Scan infrastructure code: `tfsec`, `checkov`

## Monitoring Best Practices

### The Four Golden Signals

1. **Latency**: How long requests take
   ```
   Alert: p99 latency > 500ms for 5 minutes
   ```

2. **Traffic**: How many requests
   ```
   Metric: requests_per_second
   ```

3. **Errors**: Rate of failed requests
   ```
   Alert: error_rate > 1% for 5 minutes
   ```

4. **Saturation**: How "full" the service is
   ```
   Alert: cpu_usage > 80% for 10 minutes
   ```

### Alerting Rules

**Good Alert:**
- Actionable (clear what to do)
- Relevant (impacts users or will soon)
- Timely (alerts before total failure)

**Bad Alert:**
- "Service X is down" (which service? what action?)
- Noisy (alerts constantly, team ignores)
- Too late (already impacting users)

## Red Flags - STOP

**Documentation & Research:**
- ❌ **"I know how Kubernetes works"** → DANGEROUS. Model cutoff January 2025. WebSearch current K8s version docs.
- ❌ **"Infrastructure tools don't change much"** → WRONG. Security patches, API changes, deprecations happen constantly.
- ❌ **"Using the Docker pattern I remember"** → Outdated patterns may have security vulnerabilities. Verify current best practices.

**Git/GitHub (Infrastructure PRs):**
- ❌ **"Committing Terraform to main/master"** → Use feature branch (infra/{name})
- ❌ **"Creating PR when infrastructure is deployed"** → Create DRAFT PR at start, before applying changes
- ❌ **"Using `git` when `gh` available"** → Prefer `gh pr create`, `gh pr ready`, `gh pr merge`

**Incremental Infrastructure:**
- ❌ **"Big bang infrastructure migration"** → DANGEROUS. Break into incremental changes with rollback points.
- ❌ **"Deploy all changes at once to save time"** → Increases blast radius. Deploy incrementally with validation between steps.
- ❌ **"No rollback plan needed, this will work"** → FORBIDDEN. Every infrastructure change needs tested rollback procedure.

**Operational Safety:**
- ❌ **"I'll skip the rollback plan, this deployment will work"** - DANGEROUS. All deployments need rollback plans. Optimism ≠ reliability.
- ❌ **"Monitoring can be added later"** - NO. Deploy monitoring BEFORE the service. You can't fix what you can't see.
- ❌ **"Hardcoded credentials are fine for now"** - FORBIDDEN. Use secrets management from day 1. "For now" becomes permanent.
- ❌ **"Test in production first"** - BACKWARDS. Test in staging first. Production is for users, not experiments.
- ❌ **"This infrastructure change is small, no ADR needed"** - Wrong. If it affects production, document it.
- ❌ **"Manual deployment is faster than automation"** - SHORT-TERM THINKING. Manual = error-prone and doesn't scale.

**STOP. Use wolf-governance to verify deployment requirements.**
