infrastructure

infrastructure is a skill for Claude Code, Codex from doancan/mags. It costs 56 tokens per session (2,691 once invoked), scanned A, original, MIT.

A set of infrastructure and DevOps guidelines for deploying and operating software, including CI/CD, containers, cloud systems, monitoring, and scaling. CI/CD means automatically building, testing, and releasing code.

In plain words
What is it for?
Use it to prepare production deployments, configure service health checks, plan container operations, handle migrations, and document rollback procedures.
Why use it?
It provides checks for safer releases, reliable health monitoring, graceful shutdowns, database changes, and tested rollbacks when a deployment goes wrong.

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

infrastructure 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 3d 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.

Infrastructure

Deployment Checklist

Complete every item before deploying to production:

  • Environment parity: Verify that staging mirrors production in configuration, dependency versions, and infrastructure topology. Test the exact artifact (container image, binary) that will be deployed to production.
  • Health checks: Ensure every service exposes a health endpoint (/health or /healthz) that checks database connectivity, cache availability, and critical dependency status. Configure the orchestrator (Kubernetes, ECS) to use this endpoint for readiness and liveness probes.
  • Graceful shutdown: Handle SIGTERM signals properly. Stop accepting new requests, finish in-flight requests (with a timeout of 30 seconds), close database connections, and flush logs before exiting.
  • Rollback plan: Document the exact rollback procedure before deploying. For container deployments, keep the previous image tag available. For database changes, have a tested rollback migration. Verify the rollback procedure works in staging first.
  • Database migrations: Run migrations before deploying new application code. Ensure migrations are backward-compatible with the currently running version (see Database Migrations section). Never run destructive migrations during deployment.
  • Feature flags: Gate new features behind feature flags for critical releases. This allows disabling a feature without a full rollback. Use a feature flag service (LaunchDarkly, Unleash, or a simple config-based system).
  • DNS and SSL: Verify DNS records point to the correct endpoints. Check SSL certificate expiration dates (must be more than 30 days out). Confirm TLS 1.2+ is enforced and older protocols are disabled.
  • Smoke tests: Run automated smoke tests immediately after deployment. Test critical user paths: authentication, core business operations, and external integrations. Automate these in the CI/CD pipeline as a post-deploy step.
  • Monitoring and alerting: Confirm that dashboards are updated for the new version. Verify alert thresholds are set for error rate spikes, latency increases, and resource exhaustion. Assign an on-call engineer for the deployment window.
  • Communication: Notify the team before and after deployment. For user-facing changes, update status pages and changelogs.

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.

infrastructure is a skill published in the GitHub repository doancan/mags (3 stars, last pushed 6mo ago), licensed MIT. It adds 56 tokens to every session and 2,691 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
