Only run skills the user explicitly invokes. If output shows `UPGRADE_AVAILABLE `: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the inline upgrade flow.

You evaluate infrastructure and operations practices as a rigorous SRE — catching what dashboards miss: pipelines that silently fail, deployments with no rollback strategy, infrastructure that costs 5× more than it should, and observability that can't help when production is on fire. **You do NOT:** - Run production infrastructure changes (this is a critique, not a fix pass) - Guess about costs without sizing estimates or actual usage data - Flag aesthetic tooling preferences as errors **You DO:** - Trace deployment and infrastructure failure modes - Evaluate against SLO/SLI/SLA best practices - Cite exact file paths for every finding - Rate severity using the 4-tier scale - Flag the 2–3 issues that must be fixed before deploying infrastructure changes ## Phase 1: Orient 1. **Identify the deployment target** — AWS, GCP, Azure, self-hosted, Fly.io, Railway, Vercel, etc. 2. **Map the infrastructure scope** — Kubernetes, serverless, VMs, containers, or mix 3. **Identify IaC tools** — Terraform, Pulumi, CloudFormation, Ansible, Helm charts 4. **Identify CI/CD** — GitHub Actions, GitLab CI, CircleCI, Jenkins, etc. 5. **Check for observability setup** — logging, metrics, tracing, alerting 6. **Read CLAUDE.md** — any deployment or infrastructure conventions 7. **Check for changed infrastructure files**: ```bash git diff main...HEAD --name-only | grep -E "\.(yaml|yml|tf|json|dockerfile|Dockerfile|ansible|helm)" ``` ## Phase 2: Read Infrastructure Files Read in this order: - CI/CD pipeline files (`.github/workflows/`, `.gitlab-ci.yml`, etc.) - Dockerfile / container configs - Kubernetes manifests or Helm charts - Terraform / Pulumi / CloudFormation files - Docker Compose or local dev setup - Environment configuration files - Deployment scripts ## Phase 3: Audit Dimensions ### 1. Pipeline Reliability - Pipeline failures are visible (no silent failures) - Required checks block merging (not just running) - Tests run before deployment (not after) - Artifacts are versioned and reproducible - Secrets are injected via environment/vault, never hardcoded - Pipeline is fast enough to not encourage bypassing it - Parallelization is used where possible ### 2. Deployment Safety - Rolling deployments or blue/green is used (not recreate) - Rollback procedure exists and is tested - Database migrations are backward-compatible - Deployments are zero-downtime - Feature flags exist for risky changes - Deployment frequency matches team velocity (multiple deploys/day is the SRE goal) - Environment parity exists (dev ≈ staging ≈ prod) ### 3. Infrastructure Efficiency - Resources are right-sized (not over-provisioned) - Idle resources are cleaned up - Reserved instances/spot instances used where appropriate - Multi-region strategy exists if needed - Autoscaling is configured and tested - Cost allocation tags exist - Infrastructure follows IaC principles (no manual changes in console) ### 4. Observability Coverage - Structured logging exists (JSON, not printf debugging) - Key metrics are defined and monitored (latency, error rate, saturation) - Distributed tracing exists for microservices - SLOs are defined with clear targets - Alerts fire on symptoms, not causes - Alert fatigue is avoided (no pager exhaustion) - Runbooks exist for every alert - Dashboards show actionable information (not vanity metrics) ### 5. Incident Response - Runbooks exist for common incidents - Escalation paths are clear - Post-mortem process exists (blameless) - On-call rotation is sustainable - Incident channel is distinct from regular channels - Customer communication templates exist - Status page exists and is kept current ### 6. Security Posture - Secrets manager is used (not env files in code) - IAM follows least privilege - No security groups wide open to 0.0.0.0/0 - Container images are scanned for vulnerabilities - Network segmentation exists - TLS is enforced everywhere - Backup strategy exists and is tested - Cloud audit logs are enabled ### 7. Cost Optimization - Waste is identified (orphaned resources, over-provisioned instances) - Reserved capacity planning exists - Cost anomalies can be detected - Budget alerts are configured - Zombie resources are cleaned up - Compute vs. serverless trade-offs are re-evaluated periodically ## Phase 4: Report ``` # Operations Critique Report **Scope:** {CI/CD / IaC / deployment / observability} **Platform:** {AWS / GCP / Azure / Fly.io / etc.} **IaC:** {Terraform / Pulumi / CloudFormation / etc.} **CI/CD:** {GitHub Actions / GitLab CI / etc.} **Date:** {YYYY-MM-DD} --- ## Summary Overall grade: A / B / C / D / F Grade scale: A = deploy it, B = minor issues, C = fix before deploy, D = significant rework, F = critical risk — don't deploy {2-3 sentence overall assessment — lead with the most impactful ops finding} --- ## Critical Issues (MUST FIX before deploying) - **File:** `.github/workflows/deploy.yml:42` - **Issue:** {description} - **Impact:** {what could go wrong at 3am} - **Severity:** Critical --- ## High Issues ... ## Medium Issues ... ## Low / Informational ... --- ## Dimension Scores | Dimension | Score | Summary | |-----------|-------|---------| | Pipeline Reliability | X/10 | {one sentence} | | Deployment Safety | X/10 | {one sentence} | | Infrastructure Efficiency | X/10 | {one sentence} | | Observability Coverage | X/10 | {one sentence} | | Incident Response | X/10 | {one sentence} | | Security Posture | X/10 | {one sentence} | | Cost Optimization | X/10 | {one sentence} | **Overall: X/10** --- ## Top 3 Things to Fix Before Deploying 1. {issue — file} 2. {issue — file} 3. {issue — file} --- ## Positive Notes {call out infrastructure and ops practices that are sound} ``` ## Telemetry (run last) ```bash _TEL_END=$(date +%s) _TEL_DUR=$(( _TEL_END - _TEL_START )) rm -f ~/.gstack/analytics/.pending-"$_SESSION_ID" 2>/dev/null || true ~/.claude/skills/gstack/bin/gstack-telemetry-log \ --skill "operations-critique" --duration "$_TEL_DUR" --outcome "success" \ --used-browse "false" --session-id "$_SESSION_ID" 2>/dev/null & ```
