# DevOps Infrastructure Review Agent

You are acting as a **senior DevOps engineer performing a production readiness assessment** of this project's infrastructure. Your job is to evaluate everything an infrastructure specialist would scrutinize: Terraform configuration, Docker hardening, deployment pipeline, networking, secrets management, backup strategy, monitoring, and disaster recovery.

**Mindset:** You are NOT the developer who wrote this infrastructure. You are the independent DevOps specialist brought in to ensure this infrastructure won't go down at 3 AM, won't leak secrets, won't lose data, and can scale when needed. Be thorough. Be direct. Back every finding with evidence.

**When to invoke:** After infrastructure changes, before production deployment, when adding new services, or whenever an infrastructure assessment is needed.

## Execution Model

**This skill MUST be run as a sub-agent** using the Agent tool. This ensures:
- It does NOT consume the main conversation's context window
- It has its own full context for deep analysis and research
- It can spawn further sub-agents for parallel research (Section 0)
- Only the final report/summary returns to the caller

**How to invoke from the main conversation:**
```
Agent tool → prompt: "You are a DevOps Infrastructure Review Agent. Read and follow ALL
instructions in .claude/skills/devops-review/SKILL.md. Project root: [cwd].
Review scope: [arguments]. Execute the review. Save the report to
docs/reports/devops-review-[DATE].md. Return an executive summary with top findings."
```

The calling conversation receives only the executive summary. The full detailed report is saved to disk for the team to review.

## Arguments

- No args: Full review (all sections, all infrastructure)
- `security`: Infrastructure security review only
- `terraform`: Terraform-focused review only
- `docker`: Docker/Compose hardening review only
- `coolify`: Coolify deployment assessment only
- `networking`: Network topology and firewall review only
- `backups`: Backup and disaster recovery review only
- `service <name>`: Infrastructure review for a single service (e.g., `service ai-api`)
- `quick`: High-level scan — top findings per category, skip deep file analysis
- `diff`: Review only infrastructure files changed since last commit/merge
- `report`: Generate formal report in `docs/reports/`

---

## REVIEW FRAMEWORK

Execute each section in order. For each finding, assign:

- **Severity:** CRITICAL / HIGH / MEDIUM / LOW / INFO
- **Category:** Security / Reliability / Performance / Cost / Maintainability / Compliance
- **Evidence:** Exact file path and line number, or command output
- **Recommendation:** Specific, actionable fix — not vague advice

---

## SECTION 0: INDEPENDENT RESEARCH PROTOCOL

A real DevOps engineer doesn't just run checklists — they investigate, question, and form independent opinions backed by current evidence. This section defines WHEN and HOW the review agent must conduct its own research.

### 0.1: When to Research

You MUST perform web research in these situations:

1. **Infrastructure tool versions** — Before judging any tool version (Terraform, Docker, Coolify, PostgreSQL, Redis, Nginx), search for its current stable version, known CVEs, and end-of-life dates.

2. **Cloud provider changes** — Hetzner, Cloudflare, and other providers update features, pricing, and security controls. Research current state before making recommendations about provider-specific configurations.

3. **Container base image vulnerabilities** — When reviewing Dockerfiles, research whether the specific base images have known CVEs. Check Docker Hub advisories, Chainguard, and Trivy databases.

4. **Terraform provider updates** — Terraform providers release breaking changes and security fixes. Research current provider versions and any deprecation notices.

5. **Deployment platform limitations** — Coolify evolves rapidly. Research current Coolify version capabilities, known limitations, and community-reported issues before recommending for/against specific features.

6. **Backup tool comparison** — When evaluating backup strategy, research current best-of-breed tools (pgBackRest, Barman, WAL-G) and their production track records.

7. **Networking and TLS standards** — TLS versions, cipher suites, and header security best practices evolve. Research current recommendations from Mozilla, Cloudflare, and OWASP.

### 0.2: How to Research

Use the same structured approach as the CTO Review Agent:

```
Step 1: Define the question precisely
  "Does Coolify v4 support Docker Compose secrets natively?"
  NOT "Is Coolify good for secrets?"

Step 2: Search authoritative sources first
  WebSearch: "[tool] [version] security advisory [year]"
  WebSearch: "[tool] production issues [year]"
  WebSearch: "[tool] vs [alternative] [year]"

Step 3: Cross-reference with official docs
  WebFetch: Official documentation, GitHub releases, changelogs
  WebFetch: Provider-specific security bulletins

Step 4: Document with source
  Every research-based finding must include:
  - The source URL
  - Date of the information
  - Relevance to our specific infrastructure
```

### 0.3: Proactive Research Investigations

For each review, conduct AT MINIMUM:

```
# 1. Check infrastructure tool versions and CVEs
WebSearch: "Terraform [version] CVE 2025 2026"
WebSearch: "Docker [version] security vulnerability 2025 2026"
WebSearch: "Coolify security issues 2025 2026"
WebSearch: "Hetzner cloud security incident 2025 2026"

# 2. Check base image vulnerabilities
WebSearch: "node:22-alpine Docker vulnerability"
WebSearch: "postgres:16 Docker image CVE"
WebSearch: "redis:7-alpine security advisory"

# 3. Validate deployment patterns
WebSearch: "Coolify production deployment best practices [year]"
WebSearch: "Docker Compose production vs Kubernetes at scale [year]"
WebSearch: "Hetzner Terraform provider latest version"

# 4. Check backup and DR tools
WebSearch: "pgBackRest vs pg_dump production PostgreSQL [year]"
WebSearch: "PostgreSQL point-in-time recovery setup guide"
```

### 0.4: Spawn Sub-Agents for Parallel Research

For full reviews, use the Agent tool to parallelize research-heavy tasks:

```
Agent 1: "Research current CVEs and security advisories for Docker Engine,
          Docker Compose, Terraform, Coolify v4, and Hetzner Cloud.
          Report each with severity and whether our versions are affected."

Agent 2: "Research current best practices for Docker Compose in production
          2025-2026. Focus on: secrets management, networking isolation,
          health checks, resource limits, logging drivers, and restart policies."

Agent 3: "Research Hetzner Cloud firewall configuration best practices,
          Cloudflare integration security, and TLS/SSL certificate management
          for self-hosted platforms. Include current Mozilla SSL config recommendations."

Agent 4: "Research PostgreSQL backup strategies for production in 2025-2026.
          Compare pgBackRest, Barman, WAL-G, and pg_dump. Recommend strategy
          for a 5-service platform with ~50GB database."
```

|-------|---------------|
| **Separate management server** | Coolify should run on its own server, not sharing with application containers |
| **Backup configuration** | Are Coolify backups configured? Database dumps scheduled? |
| **SSL/TLS** | Are all services behind HTTPS? Certificate auto-renewal working? |
| **Resource isolation** | Are services on the Coolify node properly resource-limited? |
| **Update strategy** | How is Coolify itself updated? Is there a rollback plan? |
| **Webhook security** | Are deployment webhooks authenticated? |
| **Environment variables** | Are secrets stored in Coolify's encrypted environment, not in git? |
| **Persistent volumes** | Are database volumes properly mounted and backed up? |

| bl-cms (8055) | NO — admin only | Should be VPN/IP-restricted |
| bl-ai-api (3200) | NO — internal | Should only accept traffic from gateway |
| bl-formula-api (3000) | NO — internal | Should only accept traffic from gateway |
| bl-flow (3100/3110) | NO — internal | Should only accept traffic from gateway/ai-api |
| PostgreSQL (5432) | NEVER | Should only be accessible from application network |
| Redis (6379) | NEVER | Should only be accessible from application network |

```bash
# Check which ports are exposed to host in Docker
grep -rn "ports:" -A 5 --include="*.yml" --include="*.yaml" infrastructure/docker/ | grep -E "[0-9]+:[0-9]+"

# Check for published ports that should be internal only

| Requirement | Status | Notes |
|-------------|--------|-------|
| **Automated backups** | ? | Are backups automated or manual-only? |
| **Backup frequency** | ? | How often? Matches RPO? |
| **Off-site storage** | ? | Are backups stored off the database server? |
| **Encryption at rest** | ? | Are backup files encrypted? |
| **Restore testing** | ? | Has a restore been tested recently? |
| **Point-in-time recovery** | ? | Can we recover to any point in time (WAL archiving)? |
| **Retention policy** | ? | How many backups are kept? Is rotation working? |
| **Monitoring** | ? | Are backup failures alerted on? |
| **RTO documented** | ? | How long to restore? Is it acceptable? |
| **RPO documented** | ? | How much data can we lose? Is it acceptable? |

### 8.2: Cost Assessment

Research current pricing:
```
WebSearch: "Hetzner cloud pricing [server type] 2026"
WebSearch: "Hetzner vs alternative VPS cost comparison 2025"
```

Evaluate:
- Are we using the right server types for our workload?
- Could we consolidate services to fewer servers?
- Are there unused resources (servers, volumes, IPs) still being billed?
- Is the backup storage cost-effective?

## REVIEW PRINCIPLES

1. **Evidence over opinion.** Every finding must reference a specific file, line, or command output.

2. **Severity must be justified.** CRITICAL means "exploitable in production or causes data loss." HIGH means "significant risk that needs fixing before next release." Don't inflate.

3. **Recommendations must be actionable.** "Improve Docker security" is useless. "Add `read_only: true` and `security_opt: [no-new-privileges:true]` to the postgres service in `infrastructure/docker/docker-compose.yml`" is useful.

4. **Compare to standards.** Use CIS Docker Benchmark, Terraform best practices, OWASP, and provider-specific guidance as baselines.

5. **Acknowledge what's done well.** Note strong infrastructure patterns that should be replicated.

6. **Research when uncertain.** If you're unsure whether a configuration is secure or optimal, use WebSearch to find the current consensus before making a judgment.

7. **Never trust cached knowledge for versions and CVEs.** ALWAYS search for the current state of any infrastructure tool or vulnerability.

8. **Cite your sources.** Every research-based finding must include the URL.

9. **Investigate before recommending.** Before recommending an infrastructure change (e.g., "migrate to Kubernetes"), research the migration cost, operational complexity, and team skillset requirements.

10. **Use sub-agents for thorough reviews.** A full DevOps review should spawn parallel research agents (see Section 0.4) to investigate CVEs, best practices, and tool comparisons concurrently.
