## What it does

Configured to run on the `sonnet` model, this subagent focuses on structured infrastructure diagnostics. It relies on telemetry data, correlating traces across Jaeger or OpenTelemetry with logs from ELK and Loki, as well as Prometheus metrics. It gathers facts before forming any diagnostic hypotheses.

The subagent handles outages across containers and cloud networks. It assists with `kubectl` inspection commands, OOMKilled containers, DNS propagation issues via `dig`, and latency capture with `tcpdump`. It also steps in when CI/CD workflows stall, deployments in ArgoCD fail, or Terraform state files drift.

Accurate troubleshooting depends on providing the agent with raw console output, traces, or CLI logs from your AWS, Azure, GCP, or OCI environments.

## Requirements
- Works with: Kubernetes

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install cicd-automation@claude-code-workflows
```

2. **Manually: put the files in place**
- File: `.claude/agents/devops-troubleshooter.md` — For all projects use ~/.claude/agents/. Claude delegates by the description field or an @-mention

### Codex

**Manually: put the files in place**
- File: `.codex/agents/devops-troubleshooter.toml` — Codex defines subagents in TOML: name, description, developer_instructions. Move the Markdown text into developer_instructions by hand. For all projects use ~/.codex/agents/

### Cursor

**Manually: put the files in place**
- File: `.cursor/agents/devops-troubleshooter.md` — Cursor also reads .claude/agents/

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wshobson/agents/tree/HEAD/plugins/cicd-automation/agents/devops-troubleshooter.md

## When to use it
- diagnose OOMKilled containers and pod crashes in Kubernetes
- locate root causes of CI/CD pipeline and build failures
- inspect network latency and DNS resolution bottlenecks
- trace database deadlocks and connection pool exhaustion

## Example prompts
- Analyze these container logs and explain why the pod entered a CrashLoopBackOff state.
- Debug this failed CI/CD pipeline step using the provided console output.
- Check this Terraform drift output and recommend steps to reconcile the state.
