This skill provides a comprehensive toolkit to validate GitLab CI/CD configurations, catching syntax errors, structure issues, and security risks before they run.

Core Features & Use Cases

Syntax validation for .gitlab-ci.yml files and GitLab CI schema
Best practices checks (cache usage, timeouts, DAG needs, rules)
Security scanning for hardcoded secrets, insecure includes, and risky patterns
Local validation/testing with gitlab-ci-local support (when available)
Automated reporting options and JSON output for integration

Quick Start

Use the validator to verify your GitLab CI config: bash .claude/skills/gitlab-ci-validator/scripts/validate_gitlab_ci.sh .gitlab-ci.yml

FAQPage Schema

How do I validate and lint a .gitlab-ci.yml file locally?▼

You can validate a .gitlab-ci.yml file locally by running the included shell script against your configuration. The validator performs syntax checks, structure analysis, and security auditing on your GitLab CI pipeline configuration before merges.

What does GitLab CI security scanning check for in a pipeline configuration?▼

GitLab CI security scanning checks for hardcoded secrets, insecure includes, and risky patterns in your configuration. It helps secure GitLab CI/CD pipelines by identifying potential vulnerabilities before the pipeline runs.

Do I need Python 3 to run the GitLab CI validator?▼

Yes, you need Python 3 installed to run the GitLab CI validator. The skill uses Python 3 and the pyyaml dependency to execute its included validators and shell scripts for local configuration testing.

Can I check GitLab CI best practices like cache usage and DAG rules in my pipeline?▼

Yes, you can check GitLab CI best practices including cache usage, timeouts, DAG needs, and rules. The validator analyzes your configuration to ensure adherence to these recommended patterns for optimized pipelines.

Does the GitLab CI validator support JSON output for CI/CD integration?▼

Yes, the GitLab CI validator supports automated reporting options including JSON output. This allows you to integrate validation results into your existing CI/CD workflows and automation tools.

Why use a local GitLab CI linter instead of pushing commits to test?▼

Using a local GitLab CI linter catches syntax errors, structure issues, and security risks before they run, preventing failed pushes. It validates configurations quickly across projects without triggering unnecessary pipeline executions.
