Instructions for creating and troubleshooting GitLab CI/CD pipelines, which automatically run build, test, and deployment jobs from a `.gitlab-ci.yml` file.

In plain words
What is it for?
Use it to write or repair `.gitlab-ci.yml`, replace legacy `only` and `except` rules, share templates, configure runners, or design branch and merge-request pipelines.
Why use it?
It helps resolve GitLab-specific trigger rules, shared configuration, runner selection, and migration issues that can leave jobs running at the wrong time or stuck.

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

gitlab-cicd-pipeline-design 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 12d 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.

GitLab CI/CD Pipeline Design

Purpose

GitLab CI/CD pipelines are defined entirely in one file, .gitlab-ci.yml, executed by GitLab Runners (shared, group, or project-specific) against a stages:/rules: model that differs in specifics from GitHub Actions or Jenkins even though the underlying pipeline concepts overlap (see ci-cd-pipeline-design for the vendor-neutral version). This skill covers GitLab-specific mechanics: the stages:/rules: trigger model (and why rules: has superseded the legacy only:/except:), include: for sharing pipeline templates across projects, and runner/executor configuration specifics.

When to use

  • A project needs its first .gitlab-ci.yml, or an existing one has a job that isn't running (or runs) when expected.
  • Migrating legacy only:/except: job keywords to the modern rules: syntax.
  • Sharing pipeline logic across multiple projects via include: (local, project, remote, or template includes) rather than duplicating YAML.
  • Diagnosing why a job is stuck pending (no runner picks it up) or fails only on certain runners.
  • Designing merge-request pipelines (merge_request_event) alongside branch/tag pipelines without running both redundantly on the same commit.

Prerequisites & environment

  • GitLab 15+ recommended: the rules: keyword and modern workflow: block are fully mature from GitLab 13+, but 15+ is assumed here for current defaults and deprecation warnings around only:/except:.
  • At least one available GitLab Runner registered against the project, group, or instance, with an executor type understood (shell, docker, docker+machine, kubernetes) — job tags: must match a runner's configured tags or the job stays pending forever.
  • Project or group maintainer access to configure CI/CD variables (Settings → CI/CD → Variables, marked "Protected"/"Masked" as appropriate) and to register runners.
  • For include: of remote/template files: network access from the GitLab instance to the include source (for include: remote:), or access to the referenced project (for include: project:).
