DevOps CI/CD Patterns

A collection of patterns for continuous integration and continuous deployment, where automated checks build, test, and release software through services such as GitHub Actions or GitLab CI.

In plain words
What is it for?
Use it to design pipeline files, order checks for quick failure detection, create reproducible builds, run jobs in parallel, and protect deployment credentials.
Why use it?
It helps teams get fast, repeatable feedback and reduces failures caused by manual steps, unpinned dependencies, leaked secrets, or inconsistent environments.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 CI/CD Patterns 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 2d 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.

DevOps CI/CD Patterns

Core Principles

  1. Automate Everything — Every step from linting to deployment should be codified in pipeline configuration. Manual steps introduce drift and human error.
  2. Fast Feedback Loops — Developers should know within minutes whether their change broke something. Prioritize quick checks early in the pipeline.
  3. Reproducibility — Builds must produce identical artifacts given the same inputs. Pin dependency versions, use immutable base images, and avoid relying on ambient state.
  4. Fail Fast, Fail Loud — Place the cheapest and most likely-to-fail checks first. Notify the right people immediately on failure.
  5. Security as a First-Class Concern — Secrets must never appear in logs, artifacts, or version control. Scope credentials to the narrowest permission set possible.

GitHub Actions Fundamentals

Workflows live in .github/workflows/ and are triggered by repository events. Structure jobs to maximize parallelism while respecting dependency ordering.

# .github/workflows/ci.yml
name: CI Pipeline
on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: npm
      - run: npm ci
      - run: npm run lint

  test:
    runs-on: ubuntu-latest
    needs: lint
    strategy:
      matrix:
        node-version: [18, 20, 22]
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node-version }}
          cache: npm
      - run: npm ci
      - run: npm test

See github-actions-patterns for: workflow triggers, matrix builds, reusable workflows, and composite actions.

GitLab CI Patterns

GitLab CI uses a .gitlab-ci.yml file at the repository root. Stages define the execution order, and jobs within the same stage run in parallel by default.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

DevOps CI/CD Patterns is a skill published in the GitHub repository justanesta/claude-code-resources (2 stars, last pushed 4mo ago), licensed MIT. It adds 31 tokens to every session and 2,029 once invoked, about $0.0002 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.
