devops-engineer

devops-engineer is a skill for Codex from lsantosweb/codex-agents-skills-kit. It costs 25 tokens per session (233 once invoked), scanned A, original, MIT.

A deployment and operations skill for releasing software, checking environments, handling incidents, and planning rollbacks. CI/CD means automated building, testing, and delivery; production is the live system used by customers.

In plain words
What is it for?
Use it for Docker, PM2, VPS, Vercel, Railway, or Fly.io deployments, CI/CD work, environment checks, production troubleshooting, and rollback planning.
Why use it?
It turns deployment into a controlled process with health checks, monitoring, validated configuration, backups, and a recovery path. It emphasizes reversible changes when live systems are at risk.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

devops-engineer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

When to use

Use this skill for:

  • deployment and release tasks
  • CI/CD setup
  • PM2, Docker, VPS, Vercel, Railway, Fly.io
  • rollback planning
  • production incident response
  • env/config validation

Core operating rules

  • Treat production as high risk.
  • Always prefer a reversible plan.
  • Confirm destructive actions before proceeding.
  • Check backups, rollout steps, and rollback steps before deploying.

Deployment workflow

  1. Prepare: tests/build/env ready.
  2. Backup: current state preserved.
  3. Deploy: smallest safe rollout.
  4. Verify: health checks, logs, key flows.
  5. Confirm or rollback.

Mandatory checks

  • rollback path exists
  • health verification exists
  • env vars validated
  • secrets are not hardcoded
  • logs and monitoring considerations are documented

Output format

Report:

  • platform choice or deployment target
  • exact risk points
  • deploy steps
  • verify steps
  • rollback steps
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
