Create, debug, and manage CI/CD pipelines with GitHub Actions. Use when the user needs to set up automated testing, deployment, releases, or workflows. Covers workflow syntax, common patterns, secrets management, caching, matrix builds, and troubleshooting.

Debug running Docker containers and Compose services. Use when inspecting container logs, exec-ing into running containers, diagnosing networking issues, checking resource usage, debugging multi-stage builds, troubleshooting health checks, or fixing Compose service dependencies.

Schedule and manage recurring tasks with cron and systemd timers. Use when setting up cron jobs, writing systemd timer units, handling timezone-aware scheduling, monitoring failed jobs, implementing retry patterns, or debugging why a scheduled task didn't run.

Validate data with schemas across languages and formats. Use when defining JSON Schema, using Zod (TypeScript) or Pydantic (Python), validating API request/response shapes, checking CSV/JSON data integrity, or setting up data contracts between services.

Debug DNS resolution and network connectivity. Use when troubleshooting DNS failures, testing port connectivity, diagnosing firewall rules, inspecting HTTP requests with curl verbose mode, configuring /etc/hosts, or debugging proxy and certificate issues.

Create and manage Docker sandboxed VM environments for safe agent execution. Use when running untrusted code, exploring packages, or isolating agent workloads. Supports Claude, Codex, Copilot, Gemini, and Kiro agents with network proxy controls.

Recover from developer disasters. Use when someone force-pushed to main, leaked credentials in git, ran out of disk space, killed the wrong process, corrupted a database, broke a deploy, locked themselves out of SSH, lost commits after a bad rebase, or hit any other "oh no" moment that needs immediate, calm, step-by-step recovery.

Encode, decode, and convert between data formats. Use when working with Base64, URL encoding, hex, Unicode, JWT tokens, hashing, checksums, or converting between serialization formats like JSON, MessagePack, and protobuf wire format.

Advanced git operations beyond add/commit/push. Use when rebasing, bisecting bugs, using worktrees for parallel development, recovering with reflog, managing subtrees/submodules, resolving merge conflicts, cherry-picking across branches, or working with monorepos.
